Notes

Glossary

Labyrinths and Liontaurs includes a large and specialized vocabulary, in whcih certain words have specific game meanings that have mechanical consequences when encountered. This page attempts to describe the most important ones, under these topics:

Game Terms

Things in the game

Creature: A creature is an active participant in the story or world. Creatures have hit points and stat blocks that describe them. Sometimes in the rules, the word "character" is used to refer to a creature. Creatures controlled by players are player characters, or PCs. Those controlled by the game master are non-player characters, or NPCs. Persons, monsters, PCs, and NPCs are all creatures.

Object: Objects are everything in the story or world that are not creatures. Generally they are weapons, doors, magic items, castles, carts, spoons, and so on. They have hit points but no stat block. It may seem counterintuitive, but mundane trees and plants, living things smaller than fine in size, and some hazards such as green slime are objects in the game, not creatures, since they do not have stat blocks.

Monster: Monsters are creatures that rely on racial hit dice instead of class levels for their powers and abilities. Monsters cannot gain classes or levels. They usually do not cast spells. Player characters cannot be monsters, except perhaps through house rules adopted outside this core rules system.

Person: Persons are creatures that can gain classes and advance in class levels. They are inherently magical and gain caster levels, and can usually cast spells. All player characters are persons. Another word for "persons" in these rules is "people."

Player character (PC): These are the persons portrayed by the players.

Nonplayer character (NPC): These are creatures controlled by the game master. They may be persons or monsters.


All the levels

Level: The fundamental concept of the game is advancement and growth in power. An advancement in power is indicated by a higher level. The term "level" refers to a varieties of measurements of power. Only persons can have levels.

Class level: Class level is the measure of advancement in a class, that is, in an occupation, like fighter or wizard. A person who started the game with one class level of fighter and then advanced ("leveled up") four times has a fighter class level of 5. If the same person then decides to try wizardry, they would have a fighter class level of 5 and a wizard class level of 1.

Character level: A person's character level represents overall ability and power. Character level is the sum of all of the person's class levels. A fighter 5 / wizard 1 has a character level of 6. In general, you gain a level the first time you sleep (or rest, if you do not sleep), after gaining enough experience points. In a dreamlike state, you select the class, class ability, and non-class ability that you gain with the level from among the choices offered by the Universal System.

Caster level: Caster level represents a creature's power and ability when casting spells. When a creature casts a spell, it often contains a number of variables, such as range or damage, that are based on caster level. Caster level also determines spell slots available per day. With a few notable exceptions — like dragons — only persons have caster levels that allow the actual casting of spells. Monsters with spell-like abilities or cantrips have a caster level to determine variable effects, but not to gain spell slots.

Spell level: Spells have a level associated with them numbered from 1 to 20. There are also minor spells called cantrips that have no spell level. Spell level indicates the general power of the spell. As spellcasters gain caster levels, they learn to cast spells of a higher spell level.


Other Key Game Terms

Ability Score: Each creature has six ability scores: Strength, Intelligence, Wisdom, Dexterity, Constitution, and Charisma. These scores represent a creature's most basic attributes. The higher the score, the more raw potential and talent your character possesses.

Action: An action is a discrete measurement of time during a round of combat. Using abilities, casting spells, and making attacks all require actions to perform. There are a number of different kinds of actions, such as a standard action, move action, swift action, free action, and full-round action (see Combat).

Alignment: Alignment represents a creature's basic moral and ethical attitude. Alignment has two components: one describing whether a creature is lawful, neutral, or chaotic, followed by another that describes whether a character is good, neutral, or evil. Alignments are usually abbreviated using the first letter of each alignment component, such as LN for lawful neutral or CE for chaotic evil. Creatures that are neutral in both components are denoted by a single “N.”

Armor Class (AC): All creatures in the game have an Armor Class. This score represents how hard it is to hit a creature in combat. As with other scores, higher is better.

Base Attack Bonus (BAB): Each creature has a base attack bonus and it represents its skill in combat. As a character gains levels or Hit Dice, his base attack bonus improves. When a creature's base attack bonus reaches +6, +11, or +16, he receives an additional attack in combat when he takes a full-attack action (which is one type of full-round action; see Combat).

Bonus: Bonuses are numerical values that are added to checks and statistical scores. Most bonuses have a type, and as a general rule, bonuses of the same type are not cumulative (do not “stack”); only the greater bonus granted applies.

Check: A check is a d20 roll which may or may not be modified by another value. The most common types are attack rolls, skill checks, and saving throws.

Class: Classes represent chosen professions taken by characters and some other creatures. Classes give a host of bonuses and allow characters to take actions that they otherwise could not, such as casting spells or changing shape. As a creature gains levels in a given class, it gains new, more powerful abilities. Most PCs gain levels in the core classes or prestige classes, since these are the most powerful. Most NPCs gain levels in secondary classes, which are less powerful.

Combat Maneuver: This is an action taken in combat that does not directly cause harm to your opponent, such as attempting to trip him, disarm him, or grapple with him (see Combat).

Combat Maneuver Bonus (CMB): This value represents how skilled a creature is at performing a combat maneuver. When attempting to perform a combat maneuver, this value is added to the character's d20 roll.

Combat Maneuver Defense (CMD): This score represents how hard it is to perform a combat maneuver against this creature. A creature's CMD is used as the difficulty class when performing a maneuver against that creature.

Concentration Check: When a creature is casting a spell, but is disrupted during the casting, he must make a concentration check or fail to cast the spell (see Magic).

Damage Reduction (DR): Creatures that are resistant to harm typically have damage reduction. This amount is subtracted from any damage dealt to them from a physical source. Most types of DR can be bypassed by certain types of weapons. This is denoted by a “/” followed by the type, such as “10/cold iron.” Some types of DR apply to all physical attacks. Such DR is denoted by the “—” symbol. See Special Abilities / Damage Reduction for more information.

Difficulty Class (DC): Whenever a creature attempts to perform an action whose success is not guaranteed, he must make some sort of check (usually a skill check). The result of that check must meet or exceed the Difficulty Class of the action that the creature is attempting to perform in order for the action to be successful.

Extraordinary Abilities (Ex): Extraordinary abilities are unusual abilities that do not rely on magic to function.

Experience Points (XP): As a character overcomes challenges, defeats monsters, and completes quests, he gains experience points. These points accumulate over time, and when they reach or surpass a specific value, the character gains a level.

Feat: A feat is an ability a creature has mastered. Feats often allow creatures to circumvent rules or restrictions. Creatures receive a number of feats based off their Hit Dice, but some classes and other abilities grant bonus feats.

Game Master (GM): A Game Master is the person who adjudicates the rules and controls all of the elements of the story and world that the players explore. A GM's duty is to provide a fair and fun game.

Hit Dice (HD): Hit Dice represent a creature's general level of power and skill. As a creature gains levels, it gains additional Hit Dice. Monsters, on the other hand, gain racial Hit Dice, which represent the monster's general prowess and ability. Hit Dice are represented by the number the creature possesses followed by a type of die, such as “3d8.” This value is used to determine a creature's total hit points. In this example, the creature has 3 Hit Dice. When rolling for this creature's hit points, you would roll a d8 three times and add the results together, along with other modifiers.

Hit Points (hp): Hit points are an abstraction signifying how robust and healthy a creature is at the current moment. To determine a creature's hit points, roll the dice indicated by its Hit Dice. A creature gains maximum hit points if its first Hit Die roll is for a character class level. Creatures whose first Hit Die comes from an NPC class or from his race roll their first Hit Die normally. Wounds subtract hit points, while healing (both natural and magical) restores hit points. Some abilities and spells grant temporary hit points that disappear after a specific duration. When a creature's hit points drop below 0, it becomes unconscious. When a creature's hit points reach a negative total equal to its Constitution score, it dies.

Initiative: Whenever combat begins, all creatures involved in the battle must make an initiative check to determine the order in which creatures act during combat. The higher the result of the check, the earlier a creature gets to act.

Multiplying: When you are asked to apply more than one multiplier to a roll, the multipliers are not multiplied by one another. Instead, you combine them into a single multiplier, with each extra multiple adding 1 less than its value to the first multiple. For example, if you are asked to apply a ×2 multiplier twice, the result would be ×3, not ×4.

Penalty: Penalties are numerical values that are subtracted from a check or statistical score. Penalties do not have a type and most penalties stack with one another.

Round: Combat is measured in rounds. During an individual round, all creatures have a chance to take a turn to act, in order of initiative. A round represents 6 seconds in the game world, so there are 10 rounds in a minute.

Rounding: Occasionally the rules ask you to round a result or value. Unless otherwise stated, always round down. For example, if you are asked to take half of 7, the result would be 3.

Saving Throw: When a creature is the subject of a dangerous spell or effect, it often receives a saving throw to mitigate the damage or result. Saving throws are passive, meaning that a creature does not need to take an action to make a saving throw — they are made automatically. There are three types of saving throws: Fortitude (used to resist poisons, diseases, and other bodily ailments), Reflex (used to avoid effects that target an entire area, such as fireball), and Will (used to resist mental attacks and spells).

Skill: A skill represents a creature's ability to perform an ordinary task, such as climb a wall, sneak down a hallway, or spot an intruder. The number of ranks possessed by a creature in a given skill represents its proficiency in that skill. As a creature gains Hit Dice, it also gains additional skill ranks that can be added to its skills.

Spell: Spells can perform a wide variety of tasks, from harming enemies to bringing the dead back to life. Spells specify what they can target, what their effects are, and how they can be resisted or negated.

Spell-Like Abilities (Sp): Spell-like abilities function just like spells, but are granted through a special racial ability or by a specific class ability (as opposed to spells, which are gained by spellcasting classes as a character gains levels).

Spell Resistance (SR): Some creatures are resistant to magic and gain spell resistance. When a creature with spell resistance is targeted by a spell, the caster of the spell must make a caster level check to see if the spell affects the target. The DC of this check is equal to the target creature's SR (some spells do not allow SR checks).

Stacking: Stacking refers to the act of adding together bonuses or penalties that apply to one particular check or statistic. Generally speaking, most bonuses of the same type do not stack. Instead, only the highest bonus applies. Most penalties do stack, meaning that their values are added together. Penalties and bonuses generally stack with one another, meaning that the penalties might negate or exceed part or all of the bonuses, and vice versa.

Supernatural Abilities (Su): Supernatural abilities are magical attacks, defenses, and qualities. These abilities can be always active or they can require a specific action to utilize. The supernatural ability's description includes information on how it is used and its effects.

Turn: In a round, a creature receives one turn, during which it can perform a wide variety of actions. Generally in the course of one turn, a character can perform one standard action, one move action, one swift action, and a number of free actions. Less-common combinations of actions are permissible as well, see Combat for more details.

Special Abilities

The following special abilities include rules commonly used by a number of creatures, spells, and traps.

Table: Special Ability Types
ExtraordinarySpell-LikeSupernatural
DispelNoYesNo
Spell resistanceNoYesNo
Antimagic fieldNoYesYes
Attack of opportunityNoYesNo
Dispel: Can dispel magic and similar spells dispel the effects of abilities of that type?
Spell Resistance: Does spell resistance protect a creature from these abilities?
Antimagic Field: Does an antimagic field or similar magic suppress the ability?
Attack of Opportunity: Does using the ability provoke attacks of opportunity the way that casting a spell does?

Extraordinary Abilities (Ex): Extraordinary abilities are nonmagical. They are, however, not something that just anyone can do or even learn to do without extensive training. Effects or areas that suppress or negate magic have no effect on extraordinary abilities.

Spell-Like Abilities (Sp): Spell-like abilities, as the name implies, are magical abilities that are very much like spells. Spell-like abilities are subject to spell resistance and dispel magic. They do not function in areas where magic is suppressed or negated (such as an antimagic field). Spell-like abilities can be dispelled and counterspelled as normal. You can cast or activate only one spell or spell-like ability per round.

Supernatural Abilities (Su): Supernatural abilities are magical but not spell-like. Supernatural abilities are not subject to spell resistance and do not function in areas where magic is suppressed or negated (such as an antimagic field). A supernatural ability's effect cannot be dispelled and is not subject to counterspells. See Table: Special Ability Types for a summary of the types of special abilities.

A note on spell-like and supernatural abilities, caster level, and spell level. In general, Sp and Su abilities use your caster level to calculate variable effects such as duration and range. Sometimes, your character level or class level is used for this purpose, as listed in the effect description; in these cases, your character level or class level is your effective caster level, and is modified by effects that alter caster level (such as the sorcerer's class bonus to caster level for cantrips and spell-like abilities). Use this effective caster level for all purposes requiring a caster level, such to resist the dispel magic spell or to penetrate spell resistance. If you need to know the spell level of a spell-like ability, for example, to calculate concentration check DCs, then ...

Ability Score Bonuses

Some spells and abilities increase your ability scores. Ability score increases with a duration of 1 day or less give only temporary bonuses. For every two points of increase to a single ability, apply a +1 bonus to the skills and statistics listed with the relevant ability.

Strength: Temporary increases to your Strength score give you a bonus on Strength-based skill checks, melee attack rolls, and weapon damage rolls (if they rely on Strength). The bonus also applies to your Combat Maneuver Bonus (if you are Small or larger) and to your Combat Maneuver Defense.

Dexterity: Temporary increases to your Dexterity score give you a bonus on Dexterity-based skill checks, ranged attack rolls, initiative checks, and Reflex saving throws. The bonus also applies to your Armor Class, your Combat Maneuver Bonus (if you are Tiny or smaller), and your Combat Maneuver Defense.

Constitution: Temporary increases to your Constitution score give you a bonus on your Fortitude saving throws. In addition, multiply your total Hit Dice by this bonus and add that amount to your current and total hit points. When the bonus ends, remove this total from your current and total hit points.

Intelligence: Temporary increases to your Intelligence score give you a bonus on Intelligence-based skill checks. This bonus also applies to any spell DCs based on Intelligence.

Wisdom: Temporary increases to your Wisdom score give you a bonus on Wisdom-based skill checks and Will saving throws. This bonus also applies to any spell DCs based on Wisdom.

Charisma: Temporary increases to your Charisma score give you a bonus on Charisma-based skill checks. This bonus also applies to any spell DCs based on Charisma and the DC to resist your channeled energy.

Permanent Bonuses: Ability bonuses with a duration greater than 1 day actually increase the relevant ability score after 24 hours. Modify all skills and statistics related to that ability. This might cause you to gain skill points, hit points, and other bonuses. These bonuses should be noted separately in case they are removed.

Ability Score Damage, Penalty, and Drain

Some diseases, spells, and other abilities deal damage directly to your ability scores. This damage does not actually reduce an ability, but it does apply a penalty to the skills and statistics that are based on that ability.

For every 2 points of damage you take to a single ability, apply a -1 penalty to skills and statistics listed with the relevant ability. If the amount of ability damage you have taken equals or exceeds your ability score, you immediately fall unconscious until the damage is less than your ability score. The only exception to this is your Constitution score. If the damage to your Constitution is equal to or greater than your Constitution score, you die. Unless otherwise noted, damage to your ability scores is healed at the rate of 1 per day to each ability score that has been damaged. Ability damage can be healed through the use of spells, such as lesser restoration.

Some spells and abilities cause you to take an ability penalty for a limited amount of time. While in effect, these penalties function just like ability damage, but they cannot cause you to fall unconscious or die. In essence, penalties cannot decrease your ability score to less than 1.

Strength: Damage to your Strength score causes you to take penalties on Strength-based skill checks, melee attack rolls, and weapon damage rolls (if they rely on Strength). The penalty also applies to your Combat Maneuver Bonus (if you are Small or larger) and your Combat Maneuver Defense.

Dexterity: Damage to your Dexterity score causes you to take penalties on Dexterity-based skill checks, ranged attack rolls, initiative checks, and Reflex saving throws. The penalty also applies to your Armor Class, your Combat Maneuver Bonus (if you are Tiny or smaller), and to your Combat Maneuver Defense.

Constitution: Damage to your Constitution score causes you to take penalties on your Fortitude saving throws. In addition, multiply your total Hit Dice by this penalty and subtract that amount from your current and total hit points. Lost hit points are restored when the damage to your Constitution is healed.

Intelligence: Damage to your Intelligence score causes you to take penalties on Intelligence-based skill checks. This penalty also applies to any spell DCs based on Intelligence.

Wisdom: Damage to your Wisdom score causes you to take penalties on Wisdom-based skill checks and Will saving throws. This penalty also applies to any spell DCs based on Wisdom.

Charisma: Damage to your Charisma score causes you to take penalties on Charisma-based skill checks. This penalty also applies to any spell DCs based off Charisma and the DC to resist your channeled energy.

Ability Drain: Ability drain actually reduces the relevant ability score. Modify all skills and statistics related to that ability. This might cause you to lose skill points, hit points, and other bonuses. Ability drain can be healed through the use of spells such as restoration.

Blindsight and Blindsense

Some creatures possess blindsight, the extraordinary ability to use a nonvisual sense (or a combination senses) to operate effectively without vision. Such senses may include sensitivity to vibrations, acute scent, keen hearing, or echolocation. This makes invisibility and concealment (even magical darkness) irrelevant to the creature (though it still can't see ethereal creatures). This ability operates out to a range specified in the creature description.

Blindsense: Other creatures have blindsense, a lesser ability that lets the creature notice things it cannot see, but without the precision of blindsight. The creature with blindsense usually does not need to make Search or Spot checks to notice and locate creatures within range of its blindsense ability, provided that it has line of effect to that creature. Any opponent that cannot be seen has total concealment (50% miss chance) against a creature with blindsense, and the blindsensing creature still has the normal miss chance when attacking foes that have concealment. Visibility still affects the movement of a creature with blindsense. A creature with blindsense is still denied its Dexterity bonus to Armor Class against attacks from creatures it cannot see.

Channel Resistance

Creatures with channel resistance gain a bonus on Will saves made against channeled energy. They add their bonus to any Will saves made to halve the damage and resist the effect.

Charm and Compulsion

Many abilities and spells can cloud the minds of characters and monsters, leaving them unable to tell friend from foe—or worse yet, deceiving them into thinking that their former friends are now their worst enemies. Two general types of enchantments affect characters and creatures: charms and compulsions.

Charming another creature gives the charming character the ability to befriend and suggest courses of action to his minion, but the servitude is not absolute or mindless. Charms of this type include the various charm spells and some monster abilities. Essentially, a charmed character retains free will but makes choices according to a skewed view of the world.

Compulsion is a different matter altogether. A compulsion overrides the subject's free will in some way or simply changes the way the subject's mind works. A charm makes the subject a friend of the caster; a compulsion makes the subject obey the caster.

Regardless of whether a character is charmed or compelled, he does not volunteer information or tactics that his master doesn't ask for.

Damage Reduction

Some magic creatures have the supernatural ability to instantly heal damage from weapons or ignore blows altogether as though they were invulnerable.

The numerical part of a creature's damage reduction (or DR) is the amount of damage the creature ignores from normal attacks. Usually, a certain type of weapon can overcome this reduction (see Overcoming DR). This information is separated from the damage reduction number by a slash. For example, DR 5/magic means that a creature takes 5 less points of damage from all weapons that are not magic. If a dash follows the slash, then the damage reduction is effective against any attack that does not ignore damage reduction.

Whenever damage reduction completely negates the damage from an attack, it also negates most special effects that accompany the attack, such as injury poison, a monk's stunning, and injury-based disease. Damage reduction does not negate touch attacks, energy damage dealt along with an attack, or energy drains. Nor does it affect poisons or diseases delivered by inhalation, ingestion, or contact.

Attacks that deal no damage because of the target's damage reduction do not disrupt spells.

Spells, spell-like abilities, and energy attacks (even nonmagical fire) ignore damage reduction.

Sometimes damage reduction represents instant healing. Sometimes it represents the creature's tough hide or body. In either case, other characters can see that conventional attacks won't work.

If a creature has damage reduction from more than one source, the two forms of damage reduction do not stack. Instead, the creature gets the benefit of the best damage reduction in a given situation.

Overcoming DR: Damage reduction may be overcome by special materials, magic weapons (any weapon with a +1 or higher enhancement bonus, not counting the enhancement from masterwork quality), certain types of weapons (such as slashing or bludgeoning), and weapons imbued with an alignment.

Ammunition fired from a projectile weapon with an enhancement bonus of +1 or higher is treated as a magic weapon for the purpose of overcoming damage reduction. Similarly, ammunition fired from a projectile weapon with an alignment gains the alignment of that projectile weapon (in addition to any alignment it may already have).

Weapons with an enhancement bonus of +3 or greater can ignore some types of damage reduction, regardless of their actual material or alignment. The following table shows what type of enhancement bonus is needed to overcome some common types of damage reduction.

DR TypeWeapon Enhancement Bonus Equivalent
cold iron/silver+3
adamantine*+4
alignment-based+5
* Note that this does not give the ability to ignore hardness, like an actual adamantine weapon does

Darkvision

Darkvision is the extraordinary ability to see with no light source at all, out to a range specified for the creature. Darkvision is black-and-white only (colors cannot be discerned). It does not allow characters to see anything that they could not see otherwise; invisible objects are still invisible, and illusions are still visible as what they seem to be. Darkvision does not pierce magical darkness. Likewise, darkvision subjects a creature to gaze attacks normally. However, creatures using the stealth skill based on concealment granted by nonmagical dim or dark light are easily seen by those using darkvision (those using stealth based on cover or on concealment from other sources, such as foliage or mist, are not revealed by darkvision). The presence of light does not spoil darkvision.

Death Attacks

In most cases, a death attack allows the victim a Fortitude save to avoid the effect, but if the save fails, the character dies instantly.

Energy Drain and Negative Levels

Some spells and a number of undead creatures have the ability to drain away life and energy; this dreadful attack results in “negative levels.” These cause a character to take a number of penalties.

For each negative level a creature has, it takes a cumulative -1 penalty on all ability checks, attack rolls, combat maneuver checks, Combat Maneuver Defense, saving throws, and skill checks. In addition, the creature reduces its current and total hit points by 5 for each negative level it possesses. The creature is also treated as one level lower for the purpose of level-dependent variables (such as spellcasting) for each negative level possessed. Spellcasters do not lose any prepared spells or slots as a result of negative levels. If a creature's negative levels equal or exceed its total Hit Dice, it dies.

A creature with temporary negative levels receives a new saving throw to remove the negative level each day. The DC of this save is the same as the effect that caused the negative levels.

Some abilities and spells (such as raise dead) bestow permanent level drain on a creature. These are treated just like temporary negative levels, but they do not allow a new save each day to remove them. Level drain can be removed through spells like restoration. Permanent negative levels remain after a dead creature is restored to life. A creature whose permanent negative levels equal its Hit Dice cannot be brought back to life through spells like raise dead and resurrection without also receiving a restoration spell, cast the round after it is restored to life.

Energy Immunity and Vulnerability

A creature with energy immunity never takes damage from that energy type. If a creature has fire immunity, it also has vulnerability to cold. If a creature has cold immunity, it also has vulnerability to fire. Vulnerability means the creature takes half again as much (+50%) damage as normal from that energy type, regardless of whether a saving throw is allowed or if the save is a success or failure.

Energy Resistance

A creature with resistance to energy has the ability (usually extraordinary) to ignore some damage of a certain type per attack, but it does not have total immunity.

Each resistance ability is defined by what energy type it resists and how many points of damage are resisted. It doesn't matter whether the damage has a mundane or magical source.

When resistance completely negates the damage from an energy attack, the attack does not disrupt a spell. This resistance does not stack with the resistance that a spell might provide.

Fear

Spells, magic items, and certain monsters can affect characters with fear. In most cases, the character makes a Will saving throw to resist this effect, and a failed roll means that the character is shaken, frightened, or panicked.

Shaken: Characters who are shaken take a -2 penalty on attack rolls, saving throws, skill checks, and ability checks.

Frightened: Characters who are frightened are shaken, and in addition they flee from the source of their fear as quickly as they can. They can choose the paths of their flight. Other than that stipulation, once they are out of sight (or hearing) of the source of their fear, they can act as they want. If the duration of their fear continues, however, characters can be forced to flee if the source of their fear presents itself again. Characters unable to flee can fight (though they are still shaken).

Panicked: Characters who are panicked are shaken, and they run away from the source of their fear as quickly as they can, dropping whatever they are holding. Other than running away from the source, their paths are random. They flee from all other dangers that confront them rather than facing those dangers. Once they are out of sight (or hearing) of any source of danger, they can act as they want. Panicked characters cower if they are prevented from fleeing.

Becoming Even More Fearful: Fear effects are cumulative. A shaken character who is made shaken again becomes frightened, and a shaken character who is made frightened becomes panicked instead. A frightened character who is made shaken or frightened becomes panicked instead.

Invisibility

The ability to move about unseen is not foolproof. While they can't be seen, invisible creatures can be heard, smelled, or felt.

Invisibility makes a creature undetectable by vision, including darkvision.

Invisibility does not, by itself, make a creature immune to critical hits, but it does make the creature immune to extra damage from being a ranger's favored enemy and from sneak attacks.

A creature can generally notice the presence of an active invisible creature within 30 feet with a DC 20 Search or Spot check. The observer gains a hunch that “something's there” but can't see it or target it accurately with an attack. It's practically impossible (+20 DC) to pinpoint an invisible creature's location with a Search or Spot check. Even once a character has pinpointed the square that contains an invisible creature, the creature still benefits from total concealment (50% miss chance). There are a number of modifiers that can be applied to this DC if the invisible creature is moving or engaged in a noisy activity.

Invisible creature is... Search or Spot
In combat or speaking-20
Moving at half speed-5
Moving at full speed-10
Running or charging-20
Not moving-40
Using StealthStealth check +20
Some distance away+1 per 10 feet
Behind an obstacle (door)+5
Behind an obstacle (stone wall)+15

A creature can grope about to find an invisible creature. A character can make a touch attack with his hands or a weapon into two adjacent 5-foot squares using a standard action. If an invisible target is in the designated area, there is a 50% miss chance on the touch attack. If successful, the groping character deals no damage but has successfully pinpointed the invisible creature's current location. If the invisible creature moves, its location, obviously, is once again unknown.

If an invisible creature strikes a character, the character struck knows the location of the creature that struck him (until, of course, the invisible creature moves). The only exception is if the invisible creature has a reach greater than 5 feet. In this case, the struck character knows the general location of the creature but has not pinpointed the exact location.

If a character tries to attack an invisible creature whose location he has pinpointed, he attacks normally, but the invisible creature still benefits from full concealment (and thus a 50% miss chance). A particularly large and slow invisible creature might get a smaller miss chance.

If a character tries to attack an invisible creature whose location he has not pinpointed, have the player choose the space where the character will direct the attack. If the invisible creature is there, conduct the attack normally. If the enemy's not there, roll the miss chance as if it were there and tell him that the character has missed, regardless of the result. That way the player doesn't know whether the attack missed because the enemy's not there or because you successfully rolled the miss chance.

If an invisible character picks up a visible object, the object remains visible. An invisible creature can pick up a small visible item and hide it on his person (tucked in a pocket or behind a cloak) and render it effectively invisible. One could coat an invisible object with flour to at least keep track of its position (until the flour falls off or blows away).

Invisible creatures leave tracks. They can be tracked normally. Footprints in sand, mud, or other soft surfaces can give enemies clues to an invisible creature's location.

An invisible creature in the water displaces water, revealing its location. The invisible creature, however, is still hard to see and benefits from concealment.

A creature with the scent ability can detect an invisible creature as it would a visible one.

A creature with the Blind-Fight feat has a better chance to hit an invisible creature. Roll the miss chance twice, and he misses only if both rolls indicate a miss. (Alternatively, make one 25% miss chance roll rather than two 50% miss chance rolls.)

A creature with blindsight can attack (and otherwise interact with) creatures regardless of invisibility.

An invisible burning torch still gives off light, as does an invisible object with a light or similar spell cast upon it.

Ethereal creatures are invisible. Since ethereal creatures are not materially present, Search or Spot checks, scent, Blind-Fight, and blindsight don't help locate them. Incorporeal creatures are often invisible. Scent, Blind-Fight, and blindsight don't help creatures find or attack invisible, incorporeal creatures, but Search or Spot checks can help.

Invisible creatures cannot use gaze attacks.

Invisibility does not thwart divination spells.

Since some creatures can detect or even see invisible creatures, it is helpful to be able to hide even when invisible.

Low-Light Vision

Characters with low-light vision have eyes that are so sensitive to light that they can see twice as far as normal in dim light. Low-light vision is color vision. A spellcaster with low-light vision can read a scroll as long as even the tiniest candle flame is next to him as a source of light.

Characters with low-light vision can see outdoors on a moonlit night as well as they can during the day.

Paralysis

Some monsters and spells have the supernatural or spell-like ability to paralyze their victims, immobilizing them through magical means. Paralysis from poison is discussed in the Afflictions section.

A paralyzed character cannot move, speak, or take any physical action. He is rooted to the spot, frozen and helpless. Not even friends can move his limbs. He may take purely mental actions, such as casting a spell with no components.

A winged creature flying in the air at the time that it becomes paralyzed cannot flap its wings and falls. A swimmer can't swim and may drown.

Scent

This extraordinary ability lets a creature detect approaching enemies, sniff out hidden foes, and track by sense of smell.

A creature with the scent ability can detect opponents by sense of smell, generally within 30 feet. If the opponent is upwind, the range is 60 feet. If it is downwind, the range is 15 feet. Strong scents, such as smoke or rotting garbage, can be detected at twice the ranges noted above. Overpowering scents, such as skunk musk or troglodyte stench, can be detected at three times these ranges.

The creature detects another creature's presence but not its specific location. Noting the direction of the scent is a move action. If the creature moves within 5 feet (1 square) of the scent's source, the creature can pinpoint the area that the source occupies, even if it cannot be seen.

A creature with the Survival skill and the scent ability can follow tracks by smell, making a Survival check to find or follow a track. A creature with the scent ability can attempt to follow tracks using Survival untrained. The typical DC for a fresh trail is 10. The DC increases or decreases depending on how strong the quarry's odor is, the number of creatures, and the age of the trail. For each hour that the trail is cold, the DC increases by 2. The ability otherwise follows the rules for the Survival skill in regards to tracking. Creatures tracking by scent ignore the effects of surface conditions and poor visibility.

Creatures with the scent ability can identify familiar odors just as humans do familiar sights.

Water, particularly running water, ruins a trail for air-breathing creatures. Water-breathing creatures that have the scent ability, however, can use it in the water easily.

False, powerful odors can easily mask other scents. The presence of such an odor completely spoils the ability to properly detect or identify creatures, and the base Survival DC to track becomes 20 rather than 10.

Spell Resistance

Spell resistance is the extraordinary ability to avoid being affected by spells. Some spells also grant spell resistance.

To affect a creature that has spell resistance, a spellcaster must make a caster level check (1d20 + caster level) at least equal to the creature's spell resistance. The defender's spell resistance is like an Armor Class against magical attacks. If the caster fails the check, the spell doesn't affect the creature. The possessor does not have to do anything special to use spell resistance. The creature need not even be aware of the threat for its spell resistance to operate.

Only spells and spell-like abilities are subject to spell resistance. Extraordinary and supernatural abilities (including enhancement bonuses on magic weapons) are not. A creature can have some abilities that are subject to spell resistance and some that are not. Even some spells ignore spell resistance; see When Spell Resistance Applies, below.

A creature can voluntarily lower its spell resistance. Doing so is a standard action that does not provoke an attack of opportunity. Once a creature lowers its resistance, it remains down until the creature's next turn. At the beginning of the creature's next turn, the creature's spell resistance automatically returns unless the creature intentionally keeps it down (also a standard action that does not provoke an attack of opportunity).

A creature's spell resistance never interferes with its own spells, items, or abilities.

A creature with spell resistance cannot impart this power to others by touching them or standing in their midst. Only the rarest of creatures and a few magic items have the ability to bestow spell resistance upon another.

Spell resistance does not stack, but rather overlaps.

When Spell Resistance Applies

Each spell includes an entry that indicates whether spell resistance applies to the spell. In general, whether spell resistance applies depends on what the spell does.

Targeted Spells: Spell resistance applies if the spell is targeted at the creature. Some individually targeted spells can be directed at several creatures simultaneously. In such cases, a creature's spell resistance applies only to the portion of the spell actually targeted at that creature. If several different resistant creatures are subjected to such a spell, each checks its spell resistance separately.

Area Spells: Spell resistance applies if the resistant creature is within the spell's area. It protects the resistant creature without affecting the spell itself.

Effect Spells: Most effect spells summon or create something and are not subject to spell resistance. Sometimes, however, spell resistance applies to effect spells, usually to those that act upon a creature more or less directly, such as web.

Spell resistance can protect a creature from a spell that's already been cast. Check spell resistance when the creature is first affected by the spell.

Check spell resistance only once for any particular casting of a spell or use of a spell-like ability. If spell resistance fails the first time, it fails each time the creature encounters that same casting of the spell. Likewise, if the spell resistance succeeds the first time, it always succeeds. If the creature has voluntarily lowered its spell resistance and is then subjected to a spell, the creature still has a single chance to resist that spell later, when its spell resistance is back up.

Spell resistance has no effect unless the energy created or released by the spell actually goes to work on the resistant creature's mind or body. If the spell acts on anything else and the creature is affected as a consequence, no roll is required. Spell-resistant creatures can be harmed by a spell when they are not being directly affected.

Spell resistance does not apply if an effect fools the creature's senses or reveals something about the creature.

Magic actually has to be working for spell resistance to apply. Spells that have instantaneous durations but lasting results aren't subject to spell resistance unless the resistant creature is exposed to the spell the instant it is cast.

Successful Spell Resistance

Spell resistance prevents a spell or a spell-like ability from affecting or harming the resistant creature, but it never removes a magical effect from another creature or negates a spell's effect on another creature. Spell resistance prevents a spell from disrupting another spell.

Against an ongoing spell that has already been cast, a failed check against spell resistance allows the resistant creature to ignore any effect the spell might have. The magic continues to affect others normally.

Afflictions

From curses to poisons to diseases, there are a number of afflictions that can affect a creature. While each of these afflictions has a different effect, they all function using the same basic system. All afflictions grant a saving throw when they are contracted. If successful, the creature does not suffer from the affliction and does not need to make any further rolls. If the saving throw is a failure, the creature falls victim to the affliction and must deal with its effects.

Afflictions require a creature to make a saving throw after a period of time to avoid taking certain penalties. With most afflictions, if a number of saving throws are made consecutively, the affliction is removed and no further saves are necessary. Some afflictions, usually supernatural ones, cannot be cured through saving throws alone and require the aid of powerful magic to remove. Each affliction is presented as a short block of information to help you better adjudicate its results.

Name: This is the name of the affliction.

Type: This is the type of the affliction, such as curse, disease, or poison. It might also include the means by which it is contracted, such as contact, ingestion, inhalation, injury, spell, or trap.

Save: This gives the type of save necessary to avoid contracting the affliction, as well as the DC of that save. Unless otherwise noted, this is also the save to avoid the affliction's effects once it is contracted, as well as the DC of any caster level checks needed to end the affliction through magic, such as remove curse or neutralize poison.

Onset: Some afflictions have a variable amount of time before they set in. Creatures that come in contact with an affliction with an onset time must make a saving throw immediately. Success means that the affliction is avoided and no further saving throws must be made. Failure means that the creature has contracted the affliction and must begin making additional saves after the onset period has elapsed. The affliction's effect does not occur until after the onset period has elapsed and then only if further saving throws are failed.

Frequency: This is how often the periodic saving throw must be attempted after the affliction has been contracted (after the onset time, if the affliction has any). While some afflictions last until they are cured, others end prematurely, even if the character is not cured through other means. If an affliction ends after a set amount of time, it will be noted in the frequency. For example, a disease with a frequency of “1/day” lasts until cured, but a poison with a frequency of “1/round for 6 rounds” ends after 6 rounds have passed. Afflictions without a frequency occur only once, immediately upon contraction (or after the onset time if one is listed).

Effect: This is the effect that the character suffers each time if he fails his saving throw against the affliction. Most afflictions cause ability damage or hit point damage. These effects are cumulative, and affliction damage cannot be cured unless the underlying affliction is cured first. Other afflictions cause the creature to take penalties or other effects. These effects are sometimes cumulative, with the rest only affecting the creature if it failed its most recent save. Some afflictions have different effects after the first save is failed. These afflictions have an initial effect, which occurs when the first save is failed, and a secondary effect, when additional saves are failed, as noted in the text. Hit point and ability score damage caused by an affliction cannot be healed magically or naturally while the affliction persists.

Cure: This tells you how the affliction is cured. Commonly, this is a number of saving throws that must be made consecutively. Even if the affliction has a limited frequency, it might be cured prematurely if enough saving throws are made. Hit point damage and ability score damage is not removed when an affliction is cured. Such damage must be healed normally. Afflictions without a cure entry can only be cured through powerful spells, such as neutralize poison and remove curse. No matter how many saving throws are made, these afflictions continue to affect the target.

Curses

Careless rogues plundering a tomb, drunken heroes insulting a powerful wizard, and foolhardy adventurers who pick up ancient swords all might suffer from curses. These magic afflictions can have a wide variety of effects, from a simple penalty to certain checks to transforming the victim into a toad. Some even cause the afflicted to slowly rot away, leaving nothing behind but dust. Unlike other afflictions, most curses cannot be cured through a number of successful saving throws. Curses can be cured through magic, however, usually via spells such as remove curse and break enchantment. While some curses cause a progressive deterioration, others inflict a static penalty from the moment they are contracted, neither fading over time nor growing worse. In addition, there are a number of magic items that act like curses. See Magic Items for a description of these cursed items.

The following samples present just some of the possibilities when creating curses.

  • Diseases

    From a widespread plague to the bite of a dire rat, disease is a serious threat to common folk and adventurers alike. Diseases rarely have a limited frequency, but most have a lengthy onset time. This onset time can also be variable. Most diseases can be cured by a number of consecutive saving throws or by spells such as remove disease.

  • Poison

    No other affliction is so prevalent as poison. From the fangs of a viper to the ichor-stained assassin's blade, poison is a constant threat. Poisons can be resisted by successful saving throws and cured by powers and spells such as neutralize poison. There are four types of poison:

    Poison comes in three strengths:

    Unlike other afflictions, conditions inflicted by multiple doses of the same poison stack. Note that if additional failed poison saves stack any condition with nauseated, the result is death.

    Applying poison to a weapon or single piece of ammunition is a standard action. Whenever a character applies or readies a poison for use there is a 5% chance that he exposes himself to the poison and must save against the poison as normal. This does not consume the dose of poison. Whenever a character attacks with a poisoned weapon, if the attack roll results in a natural 1, he exposes himself to the poison. This consumes the poison on the weapon. Characters with the poison use class feature do not risk accidentally poisoning themselves.

    Poisons can be made using Craft (Alchemy). The DC to make a poison is equal to its Fortitude save DC. Rolling a natural 1 on a Craft skill check while making a poison exposes the crafter to the poison. Crafters with the poison use class feature do not risk poisoning themselves when using Craft to make poison. Using natural poison salvaged from a defeated venomous creature generally raises the default poison DCs listed above.

    Conditions

    If more than one condition affects a character, apply them all, unless otherwise noted in the descriptions below. If effects can't combine, apply the most severe effect.

    Bleed: A creature that is taking bleed damage takes the listed amount of damage at the beginning of its turn. Bleeding can be stopped by a DC 15 Heal check or through the application of any spell that cures hit point damage (even if the bleed is ability damage). Some bleed effects cause ability damage or even ability drain. Bleed effects do not stack with each other unless they deal different kinds of damage. When two or more bleed effects deal the same kind of damage, take the worse effect. In this case, ability drain is worse than ability damage.

    Blinded: The creature cannot see. It takes a -2 penalty to Armor Class, loses its Dexterity bonus to AC (if any), and takes a -4 penalty on most Strength- and Dexterity-based skill checks and on opposed Search or Spot skill checks. All checks and activities that rely on vision (such as reading and Search or Spot checks based on sight) automatically fail. All opponents are considered to have total concealment (50% miss chance) against the blinded character. Blind creatures must make a DC 10 Acrobatics skill check to move faster than half speed. Creatures that fail this check fall prone. Characters who remain blinded for a long time grow accustomed to these drawbacks and can overcome some of them.

    Broken: Items that have taken damage in excess of half their total hit points gain the broken condition, meaning they are less effective at their designated task. The broken condition has the following effects, depending upon the item.

    Confused: A confused creature is mentally befuddled and cannot act normally. A confused creature cannot tell the difference between ally and foe, treating all creatures as enemies. Allies wishing to cast a beneficial spell that requires a touch on a confused creature must succeed on a melee touch attack. If a confused creature is attacked, it attacks the creature that last attacked it until that creature is dead or out of sight.

    Roll on the following table at the beginning of each confused subject's turn each round to see what the subject does in that round.

    d%Behavior
    01-25Act normally.
    26-50Do nothing but babble incoherently.
    51-75Deal 1d8 points of damage + Str modifier to self with item in hand.
    76-100Attack nearest creature (for this purpose, a familiar counts as part of the subject's self).

    A confused creature who can't carry out the indicated action does nothing but babble incoherently. Attackers are not at any special advantage when attacking a confused creature. Any confused creature who is attacked automatically attacks its attackers on its next turn, as long as it is still confused when its turn comes. Note that a confused creature will not make attacks of opportunity against anything that it is not already devoted to attacking (either because of its most recent action or because it has just been attacked).

    Cowering: The character is frozen in fear and can take no actions. A cowering character takes a -2 penalty to Armor Class and loses his Dexterity bonus (if any).

    Dazed: The creature is unable to act normally. A dazed creature can take no actions, but has no penalty to AC.

    A dazed condition typically lasts 1 round.

    Dazzled: The creature is unable to see well because of overstimulation of the eyes. A dazzled creature takes a -1 penalty on attack rolls and sight-based Search or Spot checks. A dazzled creature treats all other creatures as concealed, including the usual 20% miss chance.

    Dead: The character's hit points are reduced to a negative amount equal to his Constitution score, his Constitution drops to 0, or he is killed outright by a spell or effect. The character's soul leaves his body. Dead characters cannot benefit from normal or magical healing, but they can be restored to life via magic. A dead body decays normally unless magically preserved, but magic that restores a dead character to life also restores the body either to full health or to its condition at the time of death (depending on the spell or device). Either way, resurrected characters need not worry about rigor mortis, decomposition, and other conditions that affect dead bodies.

    Deafened: A deafened character cannot hear. He takes a -4 penalty on initiative checks, automatically fails Search or Spot checks based on sound, takes a -4 penalty on opposed Search or Spot checks, and has a 20% chance of spell failure when casting spells with verbal components. Characters who remain deafened for a long time grow accustomed to these drawbacks and can overcome some of them.

    Disabled: A character with 0 hit points, or one who has negative hit points but has become stable and conscious, is disabled. A disabled character may take a single move action or standard action each round (but not both, nor can he take full-round actions, but he can still take swift, immediate, and free actions). He moves at half speed. Taking move actions doesn't risk further injury, but performing any standard action (or any other action the GM deems strenuous) deals 1 point of damage after the completion of the act. Unless the action increased the disabled character's hit points, he is now in negative hit points and dying.

    A disabled character with negative hit points recovers hit points naturally if he is being helped. Otherwise, each day he can attempt a DC 10 Constitution check after resting for 8 hours, to begin recovering hit points naturally. The character takes a penalty on this roll equal to his negative hit point total. Failing this check causes the character to lose 1 hit point, but this does not cause the character to become unconscious. Once a character makes this check, he continues to heal naturally and is no longer in danger of losing hit points naturally.

    Dying: A dying creature is unconscious and near death. Creatures that have negative hit points and have not stabilized are dying. A dying creature can take no actions. On the character's next turn, after being reduced to negative hit points (but not dead), and on all subsequent turns, the character must make a DC 10 Constitution check to become stable. The character takes a penalty on this roll equal to his negative hit point total. A character that is stable does not need to make this check. A natural 20 on this check is an automatic success. If the character fails this check, he loses 1 hit point. If a dying creature has an amount of negative hit points equal to its Constitution score, it dies.

    Energy Drained: The character gains one or more negative levels, which might become permanent. If the subject has at least as many negative levels as Hit Dice, he dies. See Energy Drain and Negative levels for more information.

    Entangled: The character is ensnared. Being entangled impedes movement, but does not entirely prevent it unless the bonds are anchored to an immobile object or tethered by an opposing force. An entangled creature moves at half speed, cannot run or charge, and takes a -2 penalty on all attack rolls and a -4 penalty to Dexterity. An entangled character who attempts to cast a spell must make a concentration check (DC 15 + spell level) or lose the spell.

    Exhausted: An exhausted character moves at half speed, and it cannot run or charge. It takes a -2 penalty on attacks, damage, and armor class. In addition, an exhausted creature has a -6 penalty on Spot checks as well as a -3 penalty on all other skill checks and on saves vs sleep effects. After three hours of complete rest, exhausted characters are fatigued. Exhausted is a more extreme state of weariness than fatigued, which is a more extreme state than tired.

    Fascinated: A fascinated creature is entranced by a supernatural or spell effect. The creature stands or sits quietly, taking no actions other than to pay attention to the fascinating effect, for as long as the effect lasts. A fascinated creature takes a -2 penalty on saves vs charm and compulsion, but only if it does not perceive that a spell or magical effect is being cast; a fascinated creature also takes a -4 penalty on all skill checks made as reactions, such as Spot checks. Any potential threat, such as a hostile creature approaching, allows the fascinated creature a new saving throw against the fascinating effect. Any obvious threat, such as someone drawing a weapon, casting a spell, or aiming a ranged weapon at the fascinated creature, automatically breaks the effect. A fascinated creature's ally may shake it free of the spell as a standard action.

    Fatigued: A fatigued character can neither run nor charge and takes a -1 penalty on attacks, damage, and armor class. In addition, a fatigued creature has a -4 penalty on Spot checks as well as a -2 penalty on all other skill checks and on saves vs sleep effects. After three hours of complete rest, fatigued characters are tired. Fatigued is a more extreme state of weariness than tired. Exhausted is a more extreme state of weariness.

    Flat-Footed: A character who has not yet acted during a combat, or who is for some reason startled or engrossed, is flat-footed, unable to react normally to the situation. A flat-footed character loses his Dexterity bonus to AC (if any) and cannot make attacks of opportunity.

    Frightened: A frightened creature flees from the source of its fear as best it can. If unable to flee, it may fight. A frightened creature takes a -2 penalty on all attack rolls, saving throws, skill checks, and ability checks. A frightened creature can use special abilities, including spells, to flee; indeed, the creature must use such means if they are the only way to escape. Frightened is like shaken, except that the creature must flee if possible. Panicked is a more extreme state of fear.

    Grappled: A grappled creature is restrained by a creature, trap, or effect. Grappled creatures cannot move and take a -4 penalty to Dexterity. A grappled creature takes a -2 penalty on all attack rolls and combat maneuver checks, except those made to grapple or escape a grapple. In addition, grappled creatures can take no action that requires two hands to perform. A grappled character who attempts to cast a spell must make a concentration check (DC 10 + grappler's CMB + spell level), or lose the spell. Grappled creatures cannot make attacks of opportunity.

    A grappled creature cannot use Stealth to hide from the creature grappling it, even if a special ability, such as hide in plain sight, would normally allow it to do so. If a grappled creature becomes invisible, through a spell or other ability, it gains a +2 circumstance bonus on its CMD to avoid being grappled, but receives no other benefit.

    Helpless: A helpless character is paralyzed, held, bound, sleeping, unconscious, or otherwise completely at an opponent's mercy. A helpless target is treated as having a Dexterity of 0 (-5 modifier). Melee attacks against a helpless target get a +4 bonus (equivalent to attacking a prone target). Ranged attacks get no special bonus against helpless targets. Rogues can sneak attack helpless targets.

    As a full-round action, an enemy can use a melee weapon to deliver a coup de grace to a helpless foe. An enemy can also use a bow or crossbow, provided he is adjacent to the target. The attacker automatically hits and scores a critical hit. (A rogue also gets his sneak attack damage bonus against a helpless foe when delivering a coup de grace.) If the defender survives, he must make a Fortitude save (DC 10 + damage dealt) or die. Delivering a coup de grace provokes attacks of opportunity.

    Creatures that are immune to critical hits do not take critical damage, nor do they need to make Fortitude saves to avoid being killed by a coup de grace.

    Incorporeal: Creatures with the incorporeal condition do not have a physical body. Incorporeal creatures are immune to all nonmagical attack forms. Incorporeal creatures take half damage (50%) from magic weapons, spells, spell-like effects, and supernatural effects. Incorporeal creatures take full damage from other incorporeal creatures and effects, as well as all force effects.

    Invisible: Invisible creatures are visually undetectable. An invisible creature gains a +2 bonus on attack rolls against sighted opponents, and ignores its opponents' Dexterity bonuses to AC (if any). See Invisibility, under Special Abilities.

    Nauseated: Creatures with the nauseated condition experience stomach distress. Nauseated creatures are unable to attack, cast spells, concentrate on spells, or do anything else requiring attention. The only action such a character can take is a single move action per turn. Nauseated is a more extreme state of illness than queasy or sickened.

    Panicked: A panicked creature must drop anything it holds and flee at top speed from the source of its fear, as well as any other dangers it encounters, along a random path. It can't take any other actions. In addition, the creature takes a -2 penalty on all saving throws, skill checks, and ability checks. If cornered, a panicked creature cowers and does not attack, typically using the total defense action in combat. A panicked creature can use special abilities, including spells, to flee; indeed, the creature must use such means if they are the only way to escape. Panicked is a more extreme state of fear than shaken or frightened.

    Paralyzed: A paralyzed character is frozen in place and unable to move or act. A paralyzed character has effective Dexterity and Strength scores of 0 and is helpless, but can take purely mental actions. A winged creature flying in the air at the time that it becomes paralyzed cannot flap its wings and falls. A paralyzed swimmer can't swim and may drown. A creature can move through a space occupied by a paralyzed creature—ally or not. Each square occupied by a paralyzed creature, however, counts as 2 squares to move through.

    Petrified: A petrified character has been turned to stone and is considered unconscious. If a petrified character cracks or breaks, but the broken pieces are joined with the body as he returns to flesh, he is unharmed. If the character's petrified body is incomplete when it returns to flesh, the body is likewise incomplete and there is some amount of permanent hit point loss and/or debilitation.

    Pinned: A pinned creature is tightly bound and can take few actions. A pinned creature cannot move and is flat-footed. A pinned character also takes an additional -4 penalty to his Armor Class. A pinned creature is limited in the actions that it can take. A pinned creature can always attempt to free itself, usually through a combat maneuver check or Escape Artist check. A pinned creature can take verbal and mental actions, but cannot cast any spells that require a somatic or material component. A pinned character who attempts to cast a spell must make a concentration check (DC 10 + grappler's CMB + spell level) or lose the spell. Pinned is a more severe version of grappled, and their effects do not stack.

    Prone: The character is lying on the ground. A prone attacker has a -4 penalty on melee attack rolls and cannot use a ranged weapon (except for a crossbow). A prone defender gains a +4 bonus to Armor Class against ranged attacks, but takes a -4 penalty to AC against melee attacks. Standing up is a move-equivalent action that provokes an attack of opportunity.

    Queasy: The character takes a -1 penalty on all attack rolls, saving throws, skill checks, and ability checks. Queasy is a less severe state of illness than sickened or nauseated.

    Shaken: A shaken character takes a -2 penalty on attack rolls, saving throws, skill checks, and ability checks. Shaken is a less severe state of fear than frightened or panicked.

    Sickened: The character takes a -2 penalty on all attack rolls, weapon damage rolls, saving throws, skill checks, and ability checks. Sickened is a more severe state of illness than queasy; it is less severe than nauseated.

    Stable: A character who was dying but who has stopped losing hit points each round and still has negative hit points is stable. The character is no longer dying, but is still unconscious. If the character has become stable because of aid from another character (such as a Heal check or magical healing), then the character no longer loses hit points. The character can make a DC 10 Constitution check each hour to become conscious and disabled (even though his hit points are still negative). The character takes a penalty on this roll equal to his negative hit point total.

    If a character has become stable on his own and hasn't had help, he is still at risk of losing hit points. Each hour he can make a Constitution check to become stable (as a character that has received aid), but each failed check causes him to lose 1 hit point.

    Staggered: A staggered creature may take a single move action or standard action each round (but not both, nor can he take full-round actions). A staggered creature can still take swift and immediate actions. A creature with nonlethal damage exactly equal to its current hit points gains the staggered condition.

    Stunned: A stunned creature drops everything held, can't take actions, takes a -2 penalty to AC, and loses its Dexterity bonus to AC (if any).

    Tired: A tired creature is drowsy and weary, suffering a -2 on Spot checks and a -1 on other skill checks and on saving throws vs sleep effects. Two hours of complete rest removes the tired condition. Tired is a less extreme state of weariness than fatigued or exhausted.

    Unconscious: Unconscious creatures are knocked out and helpless. Unconsciousness can result from having negative hit points (but not more than the creature's Constitution score), or from nonlethal damage in excess of current hit points.
