One of the six basic character qualities: Strength (Str), Dexterity (Dex), Constitution (Con), Intelligence (Int), Wisdom (Wis), and Charisma (Cha).

A check of 1d20 + the appropriate ability modifier.

A temporary loss of 1 or more ability score points. Lost points return at a rate of 1 point per day unless noted otherwise by the condition dealing the damage. A character with Strength 0 falls to the ground and is helpless. A character with Dexterity 0 is paralyzed. A character with Constitution 0 is dead. A character with Intelligence, Wisdom, or Charisma 0 is unconscious.

The character has temporarily lost 1 or more ability score points. Lost points return at a rate of 1 per day unless noted otherwise by the condition dealing the damage. A character with Strength 0 falls to the ground and is helpless. A character with Dexterity 0 is paralyzed. A character with Constitution 0 is dead. A character with Intelligence, Wisdom, or Charisma 0 is unconscious.

A decrease in an ability score that ends when the condition causing it does.

A permanent loss of 1 or more ability score points. The character can regain these points only through magical means. A character with Strength 0 falls to the ground and is helpless. A character with Dexterity 0 is paralyzed. A character with Constitution 0 is dead. A character with Intelligence, Wisdom, or Charisma 0 is unconscious.

The character has permanently lost 1 or more ability score points. The character can regain these points only through magical means. A character with Strength 0 falls to the ground and is helpless. A character with Dexterity 0 is paralyzed. A character with Constitution 0 is dead. A character with Intelligence, Wisdom, or Charisma 0 is unconscious.

The bonus or penalty associated with a particular ability score. Ability modifiers apply to die rolls for character actions involving the corresponding abilities.

The numeric rating of one of the six character abilities. Some creatures lack certain ability scores; others cannot be rated in particular abilities.

Some attacks reduce the opponent's score in one or more abilities. This loss can be temporary (ability damage) or permanent (ability drain). Points lost to ability damage return at the rate of 1 point per day (or double that if the character gets complete bed rest) to each damaged ability, and the spells lesser restoration and restoration offset ability damage as well. Ability drain, however, is permanent, though restoration can restore even those lost ability score points.

A character activity. Actions are divided into the following categories, according to the time required to perform them (from most time required to least): full-round actions, standard actions, move actions, and free actions.

In a square that shares a border or a corner with a designated square. Each square is adjacent to eight other squares on the board.

A group of characters who adventure together. An adventuring party is composed of player characters plus any followers, familiars, animal companions, associates, cohorts, or hirelings they might have.

This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane of Air. Air creatures always have fly speeds and usually have perfect maneuverability.

One of the nine descriptors of morality for intelligent creatures: lawful good (LG), neutral good (NG), chaotic good (CG), lawful neutral (LN), neutral (N), chaotic neutral (CN), lawful evil (LE), neutral evil (NE), and chaotic evil (CE).

A creature friendly to you. In most cases, references to "allies" include yourself.

A creature with this special quality has the ability to assume one or more specific alternate forms. This ability works much like the polymorph spell, except that the creature is limited to the forms specified, and it does not regain any hit points for changing its form. Assuming an alternate form results in the following changes to the creature:

Angels are a race of celestials, or good outsiders, native to the good-aligned Outer Planes. In the D&D cosmology, these planes are the Seven Mounting Heavens of Celestia, the Twin Paradises of Bytopia, the Olympian Glades of Arborea, the Blessed Fields of Elysium, and the Wilderness of the Beastlands.

An animal is a living, nonhuman creature, usually a vertebrate with no magical abilities and no innate capacity for language or culture.

An antimagic field spell or the main eye ray of a beholder cancels magic altogether. This spell-like effect is extremely powerful -- the ultimate defense against magic. An antimagic effect has the following powers and characteristics.

Creatures with the aquatic subtype always have swim speeds and thus can move in water without making Swim checks. An aquatic creature can breathe underwater. It cannot also breathe air unless it has the amphibious special quality.

Arcane spells involve the direct manipulation of mystic energies. Bards, sorcerers, and wizards cast arcane spells.

The chance that a spell fails and is cast to no effect because the caster's ability to use a somatic component was hampered by armor. Bards can ignore the arcane spell failure chance for light armor when casting bard spells.

Archons are a race of celestials, or good outsiders, native to the Seven Mounting Heavens of Celestia.

A bonus to Armor Class granted by armor or by a spell or magical effect that mimics armor. Armor bonuses stack with all other bonuses to Armor Class (even with natural armor bonuses) except other armor bonuses. Magic armor typically grants an enhancement bonus to the armor's armor bonus, which has the effect of increasing the armor's overall bonus. An armor bonus granted by a spell or magic item typically takes the form of an invisible, tangible field of force around the recipient. An armor bonus doesn't apply against touch attacks, except for armor bonuses granted by force effects (such as the mage armor spell) which apply against incorporeal touch attacks, such as that of a shadow.

A number representing a creature's ability to avoid being hit in combat. An opponent's attack roll must equal or exceed the target creature's Armor Class (AC) to hit it. Armor Class = 10 + all modifiers that apply (typically armor bonus, shield bonus, Dexterity modifier, and size modifier).

A magic item of incredible power. Some spells do not function when targeted on an artifact.

An open, weightless plane that connects with all other planes of existence and is used for transportation among them (and is thus described as a transitive plane, like the Ethereal Plane and the Plane of Shadow). Certain spells (such as astral projection) allow access to this plane.

Any of numerous actions intended to harm, disable, or neutralize an opponent. The outcome of an attack is determined by an attack roll.

A single extra melee attack per round that a combatant can make when an opponent within reach takes an action that provokes attacks of opportunity. Cover prevents attacks of opportunity.

A roll to determine whether an attack hits. To make an attack roll, roll 1d20 and add the appropriate modifiers for the attack type, as follows: melee attack roll = 1d20 + base attack bonus + Strength modifier + size modifier; ranged attack roll = 1d20 + base attack bonus + Dexterity modifier + size modifier + range penalty. In either case, the attack hits if the result is at least as high as the target's Armor Class.

A creature receives this subtype whenever something happens to change its original type. Some creatures (those with an inherited template) are born with this subtype; others acquire it when they take on an acquired template. The augmented subtype is always paired with the creature's original type. For example, a wizard's raven familiar is a magical beast (augmented animal). A creature with the augmented subtype usually has the traits of its current type, but the features of its original type. For example, a wizard's raven familiar has an animal's features and the traits of a magical beast.

An attack that hits regardless of target AC. Automatic hits occur on an attack roll of natural 20 or as a result of certain spells. A natural 20 attack roll is also a threat -- a possible critical hit.

An attack that misses regardless of target AC. Automatic misses occur on an attack roll of natural 1.

Many devils belong to the race of evil outsiders known as the baatezu.

A class made up of ferocious warriors who use inborn fury and instinct to bring down foes.

A class made up of performers whose music and poetics produce magical effects.

An attack roll bonus derived from character class and level. Base attack bonuses increase at different rates for different character classes. A character gains a second attack when his or her base attack bonus reaches +6, a third with a base attack bonus of +11 or higher, and a fourth with a base attack bonus of +16 or higher. Base attack bonuses gained from different classes, such as when a character is a multiclass character, stack.

The speed a character can move while unarmored. Base land speed is derived from character race.

A saving throw modifier derived from character class and level. Base save bonuses increase at different rates for different character classes. Base save bonuses gained from different classes, such as when a character is a multiclass character, stack.

A play surface marked off in 1-inch squares, which is used to keep track of the locations of creatures and characters (represented by miniature figures) during combat and other tactical situations.

Unable to see. A blinded character takes a -2 penalty to Armor Class, loses his Dexterity bonus to AC (if any), moves at half speed, and takes a -4 penalty on Search checks and on most Strength- and Dexterity-based skill checks. All checks and activities that rely on vision (such as reading and Spot checks) automatically fail. All opponents are considered to have total concealment (50% miss chance) relative to the blinded character. Characters who remain blinded for a long time grow accustomed to these drawbacks and can overcome some of them (DM's discretion).

Using nonvisual senses, such as acute smell or hearing, a creature with the blindsense extraordinary ability notices things it cannot see. The creature usually does not need to make Spot or Listen checks to pinpoint the location of a creature within range of its blindsense ability, provided that it has line of effect to that creature. Any opponent the creature cannot see still has total concealment against the creature with blindsense, and the 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.

Some creatures have blindsight, the extraordinary ability to use a nonvisual sense (or a combination of such senses) to operate effectively without vision. Such sense may include sensitivity to vibrations, acute scent, keen hearing, or echolocation. This ability makes invisibility and concealment (even magical darkness) irrelevant to the creature (though it still can't see ethereal creatures and the creature must have line of effect to a creature or object to discern that creature or object). The creature usually does not need to make Spot or Listen checks to notice creatures within range of its blindsight ability. This ability operates out to a range specified in the creature description.

Depending on its size, a creature can be blown away by winds of high velocity (see Table 3-24 in the Dungeon Master's Guide, page 95). A creature on the ground that is blown away is knocked down and rolls 1d4x10 feet, taking 1d4 points of nonlethal damage per 10 feet. A flying creature that is blown away is blown back 2d6x10 feet and takes 2d6 points of nonlethal damage due to battering and buffering.

A supernatural ability of evil clerics (and some neutral ones). Bolstering undead increases the resistance of those undead creatures to turning attempts.

A positive modifier to a die roll. In most cases, multiple bonuses from the same source or of the same type in effect on the same character or object do not stack; only the highest bonus of that type applies. Bonuses that don't have a specific type always stack with all bonuses.

A breath weapon attack usually deals damage and is often based on some type of energy (such as fire). Such breath weapons allow a Reflex save for half damage (DC 10 + 1/2 breathing creature's racial HD + breathing creature's Con modifier; the exact DC is given in the creature's descriptive text). A creature is immune to its own breath weapon unless otherwise noted. Some breath weapons allow a Fortitude save or a Will save instead of a Reflex save. Most creatures with breath weapons are limited to a number of uses per day or by a minimum length of time that must pass between uses. Such creatures are usually smart enough to save their breath weapon until they really need it.

An arcane 0-level spell.

Trigger the magical or divine energy of a spell by means of words, gestures, focuses, and/or special materials. Spellcasting requires the uninterrupted concentration of the caster during the requisite casting time. Disruption of this concentration forces the caster to make a successful Concentration check or lose the spell. Successful casting brings about the spell's listed effect or effects.

A measure of the power with which a spellcaster casts a spell. Generally, a spell's caster level is the spellcaster's class level.

A roll of 1d20 + the caster level (in the relevant class). If the result equals or exceeds the DC (or the spell resistance, in the case of caster level checks made for spell resistance), the check succeeds.

The time required to cast a spell, usually either 1 standard action, 1 round, or 1 free action. Spells with casting times longer than 1 round require full-round actions for all the rounds encompassed in the casting time.

A creature with this special quality (supernatural) has the ability to assume the appearance of a specific creature or type of creature (usually a humanoid), but retains most of its own physical qualities. A creature cannot change shape to a form more than one size category smaller or larger than its original form. Changing shape results in the following changes to the creature:

A subtype usually applied only to outsiders native to the chaotic-aligned Outer Planes. Most creatures that have this subtype also have chaotic alignments; however, if their alignments change they still retain the subtype. Any effect that depends on alignment affects a creature with this subtype as if the creature has a chaotic alignment, no matter what its alignment actually is. The creature also suffers effects according to its actual alignment. A creature with the chaotic subtype overcomes damage reduction as if its natural weapons and any weapons it wields were chaotic-aligned.

A fictional individual within the confines of a fantasy game setting. The words "character" and "creature" are often used synonymously within these rules, since almost any creature could be a character within the game, and every character is a creature (as opposed to an object).

One of the eleven player character types -- barbarian, bard, cleric, druid, fighter, monk, paladin, ranger, rogue, sorcerer, or wizard. Class defines a character's predominant talents and general function within an adventuring party. Character class may also refer to a nonplayer character class or a prestige class.

A character's total level. For a character with levels in only one class, class level and character level are the same thing.

The ability that measures a character's force of personality, persuasiveness, personal magnetism, ability to lead, and physical attractiveness.

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.

A method of determining the result when a character attempts an action (other than an attack or a saving throw) that has a chance of failure. Checks are based on a relevant character ability, skill, or other characteristic. Most checks are either ability checks or skill checks, though special types such as turning checks, caster level checks, dispel checks, and initiative checks also exist. The specific name of the check usually corresponds to the skill or ability used. To make a check, roll 1d20 and add any relevant modifiers. (Higher results are always better.) If this check result equals or exceeds the Difficulty Class number assigned by the DM (or the opponent's check, if the action is opposed), the check succeeds.

Prevented from achieving forward motion by an applied force, such as wind. Checked creatures on the ground merely stop. Checked flying creatures move back a distance specified in the description of the effect.

A bonus granted because of specific conditional factors favorable to the success of the task at hand. Circumstance bonuses stack with all other bonuses, including other circumstance bonuses, unless they arise from essentially the same benefit. For instance, a magnifying glass gives a +2 circumstance bonus on Appraise checks involving any item that is small or highly detailed, such as a gem. If you had a second tool that also granted a circumstance bonus from improved visual acuity (such as a jeweler's loupe), the circumstance bonuses wouldn't stack.

See character class.

Any special characteristic derived from a character class.

A character's level in a single class. Class features generally depend on class level rather than character level.

A skill to which characters of a particular class have easier access than characters of other classes. Characters may buy class skills at a rate of 1 rank per skill point, as opposed to 1/2 rank per skill point for cross-class skills. The maximum rank for a class skill is 3 + character level.

A class made up of characters who cast divine spells and are also capable in combat.

A creature with cold immunity, such as a frost giant, never takes cold damage. It has vulnerability to fire, which means it takes half again as much (+50%) damage as normal from fire, regardless of whether a saving throw is allowed, or if the save is a success or failure.

A creature with the cold subtype has immunity to cold. It has vulnerability to fire, which means it takes half again as much (+50%) damage as normal from fire, regardless of whether a saving throw is allowed, or if the save is a success or failure.

A Colossal creature is typically 64 feet or more in height or length and weighs 250,000 pounds or more.

Effectively in a state of suspended animation. A comatose creature is helpless.

The supernatural ability of evil clerics and some neutral clerics to control undead creatures by channeling negative energy.

A magic item that activates when the user speaks a particular word or phrase. Activating a command word item does not require concentration and does not provoke attacks of opportunity.

A bonus that improves a character's performance of a particular task, such as from the bardic ability to inspire competence. Such a bonus may apply on attack rolls, saving throws, skill checks, caster level checks, or any other checks to which a bonus relating to level or skill ranks would normally apply. It does not apply on ability checks, damage rolls, initiative checks, or other rolls that aren't related to a character's level or skill ranks. Multiple competence bonuses don't stack; only the highest bonus applies.

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.

Something that prevents an attacker from clearly seeing his or her target. Concealment creates a chance that an otherwise successful attack misses (a miss chance).

Concentrate to maintain an active spell's effect. Concentrating on a spell is a standard action and provokes an attack of opportunity.

Befuddled and unable to determine a course of action due to a spell or magical effect. A confused character's actions are determined by rolling d% at the beginning of his turn: 01-10, attack caster with melee or ranged weapons (or close with caster if attacking is not possible); 11-20, act normally; 21-50, do nothing but babble incoherently; 51-70, flee away from caster at top possible speed; 71-100, attack nearest creature (for this purpose, a familiar counts as part of the subject's self). A confused character who can't carry out the indicated action does nothing but babble incoherently. Attackers are not at any special advantage when attacking a confused character. Any confused character who is attacked automatically attacks its attackers on its next turn, as long as it is still confused when its turn comes. A confused character does not make attacks of opportunity against any creature that it is not already devoted to attacking (either because of its most recent action or because it has just been attacked).

The ability that represents a character's health and stamina.

A creature with this extraordinary special attack can crush an opponent, dealing bludgeoning damage, after making a successful grapple check. The amount of damage is given in the creature's entry. If the creature also has the improved grab ability, it deals constriction damage in addition to damage dealt by the weapon used to grab.

A construct is an animated object or artificially constructed creature.

Damage from a single attack that continues to deal damage every round without the need for additional attack rolls.

The most prevalent form of currency among beggars and laborers. Ten copper pieces are equivalent to 1 silver piece.

A full-round action that allows an attacker to attempt a killing blow against a helpless opponent. A coup de grace can be administered with a melee weapon, or with a bow or crossbow if the attacker is adjacent to the opponent. An attacker delivering a coup de grace automatically scores a critical hit, after which the defender must make a Fortitude save (DC 10 + damage dealt) or die. Rogues also gain their extra sneak attack damage for this attack. Delivering a coup de grace provokes attacks of opportunity from threatening foes. A coup de grace is not possible against a creature immune to critical hits.

Any barrier between an attacker and defender. Such a barrier can be an object, a creature, or a magical force. Cover grants the defender a bonus to Armor Class.

Frozen in fear and unable to take actions. A cowering character takes a -2 penalty to Armor Class and loses her Dexterity bonus (if any).

A living or otherwise active being, not an object. The terms "creature" and "character" are sometimes used interchangeably.

One of several broad categories of creatures. The creature types are aberration, animal, construct, dragon, elemental, fey, giant, humanoid, magical beast, monstrous humanoid, ooze, outsider, plant, undead, and vermin.

A hit that strikes a vital area and therefore deals double damage or more. To score a critical hit (crit), an attacker must first score a threat (usually a natural 20 on an attack roll) and then succeed on a critical roll (just like another attack roll). Critical hit damage is usually double damage, which means rolling damage twice, just as if the attacker had actually hit the defender two times. (Any extra damage dice, such as from a rogue's sneak attack, are not rolled multiple times, but are added to the total at the end of the calculation.)

A special second attack roll made in the event of a threat to determine whether a critical hit has been scored. If the critical roll is a hit against the target creature's AC, then the original attack is a critical hit. Otherwise, the original attack is a regular hit.

A skill that is not a class skill for a character. Characters may buy cross-class skills at the rate of a half rank per skill point, as opposed to 1 rank per skill point for class skills. The most ranks a character can have in a cross-class skill is one-half of the class skill maximum (3 + the character's level), rounded neither up nor down.

Any spell with the word "cure" in its name, such as cure minor wounds, cure light wounds, or mass cure critical wounds.

A character's hit points at a given moment in the game. Current hit points go down when the character takes damage and go back up upon recovery.

A decrease in hit points, an ability score, or other aspects of a character caused by an injury, illness, or magical effect. The three main categories of damage are lethal damage, nonlethal damage, and ability damage. In addition, wherever it is relevant, the type of damage an attack deals is specified, since natural abilities, magic items, or spell effects may grant immunity to certain types of damage. Damage types include weapon damage (subdivided into bludgeoning, slashing, and piercing) and energy damage (positive, negative, acid, cold, electricity, fire, and sonic). Modifiers to melee damage rolls apply to both subcategories of weapon damage (melee and unarmed). Some modifiers apply to both weapon and spell damage, but only if so stated. Damage points are deducted from whatever character attribute has been harmed -- lethal and nonlethal damage from current hit points, and ability damage from the relevant ability score). Damage heals naturally over time, but can also be negated wholly or partially by curative magic.

A creature with this special quality (extraordinary or supernatural) ignores damage from most weapons and natural attacks. Wounds heal immediately, or the weapon bounces off harmlessly (in either case, the opponent knows the attack was ineffective). The creature takes normal damage from energy attacks (even nonmagical ones), spells, spell-like abilities, and supernatural abilities. A certain kind of weapon can sometimes damage the creature normally, as noted below.

Darkvision is the extraordinary ability to see with no light source at all, out to a range specified for the creature.

Unable to act normally. A dazed character can take no actions, but has no penalty to AC. A dazed condition typically lasts 1 round.

Unable to see well because of overstimulation of the eyes. A dazzled creature takes a -1 penalty on attack rolls, Spot checks, and Search checks.

A character dies when his or her hit points drop to -10 or lower. A character also dies when his or her Constitution drops to 0, and certain spells or effects (such as failing a Fortitude save against massive damage) can also kill a character outright. Death causes the character's soul to leave the body and journey to an Outer Plane. 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.

Unable to hear. A deafened character takes a -4 penalty on initiative checks, automatically fails Listen 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 (DM's discretion).

Cause damage to a target with a successful attack. How much damage is dealt is usually expressed in terms of dice (for example, 2d6+4) and may have a situational modifier as well. However, damage dealt by a weapon or spell does not necessarily equal damage taken by the target, because the target may have special defenses that negate some or all of the damage.

A spell or special ability that instantly slays the target, such as finger of death. Neither raise dead nor reincarnation can grant life to a creature slain by a death attack, though resurrection and more powerful effects can. In most cases, a death attack allows the victim a Fortitude save to avoid the affect, but if the save fails, the character dies instantly. A victim cannot be made stable and thereby kept alive. In case it matters, a dead character, no matter how she died, has -10 hit points. The spell death ward protects a character against these attacks.

A bonus to Armor Class granted by a spell or magic effect that makes attacks veer off harmlessly. Deflection bonuses stack with all other bonuses to AC except other deflection bonuses. A deflection bonus applies against touch attacks.

The ability that measures a character's hand-eye coordination, agility, reflexes, and balance.

An area containing one or more features (such as rubble or undergrowth) that costs 2 squares instead of 1 square to move through.

The target number that a player must meet or beat for a check or saving throw to succeed. Difficulty Classes other than those given in specific spell or item descriptions are set by the DM using the skill rules as a guideline.

A Diminutive creature is typically between 6 inches and 1 foot in height or length and weighs between 1/8 pound and 1 pound.

Direct an active spell's effect at a specific target or targets. Directing a spell is a move action and does not provoke an attack of opportunity.

At exactly 0 current hit points, or in negative hit points but stable and conscious. A disabled character may take a single move action or standard action each round (but not both, nor can she take full-round actions). She moves at half speed. Taking move actions doesn't risk further injury, but performing any standard action (or any other action the DM deems strenuous, including some free actions such as casting a quickened spell) deals 1 point of damage after the completion of the act. Unless the action increased the disabled character's hit points, she is now in negative hit points and dying.

When a character is injured by a contaminated attack (such as a mummy's slam attack, which can transmit mummy rot), touches an item smeared with diseased matter, or consumes disease-tainted food or drink, he must make an immediate Fortitude saving throw. If he succeeds, the disease has no effect -- his immune system fought off the infection. If he fails, he takes damage after an incubation period. Once per day afterward, he must make a successful Fortitude saving throw to avoid repeated damage. Two successful saving throws in a row indicate that he has fought off the disease and recovers, taking no more damage.

Negate, suppress, or remove one or more existing spells or other effects on a creature, item, or area. Dispel usually refers to a dispel magic spell, though other forms of dispelling are possible. Certain spells cannot be dispelled, as noted in the individual spell descriptions.

A roll of 1d20 + caster level of the character making the attempt to dispel (usually used with dispel magic). The DC is 11 plus the level of the spellcaster who initiated the effect being dispelled.

Channel negative energy to negate a successful turning undead attempt by a good cleric or a paladin.

Spells of religious origin powered by faith or by a deity. Clerics, druids, paladins, and rangers cast divine spells.

A bonus to Armor Class (and sometimes Reflex saves) resulting from physical skill at avoiding blows and other ill effects. Dodge bonuses are never granted by spells or magic items. Any situation or effect (except wearing armor) that negates a character's Dexterity bonus also negates any dodge bonuses the character may have (for instance, you lose any dodge bonuses to AC when you're flat-footed). Dodge bonuses stack with all other bonuses to AC, even other dodge bonuses. Dodge bonuses apply against touch attacks.

A granted power and a set of nine divine spells (one each of 1st through 9th level) themed around a particular concept and associated with one or more deities. The available domains are: Air, Animal, Chaos, Death, Destruction, Earth, Evil, Fire, Good, Healing, Knowledge, Law, Luck, Magic, Plant, Protection, Strength, Sun, Travel, Trickery, War, and Water.

A divine spell belonging to a domain. Each domain offers one spell of each spell level. In addition to their normal daily complement of spells, clerics can cast one domain spell per day for each spell level that their caster levels allow. This spell may be from either of their domains. Domain spells cannot be exchanged for cure or inflict spells.

A weapon with two ends, blades, or heads that are both intended for use in combat. Any weapon for which two damage ranges are listed is a double weapon. Double weapons can be used to make an extra attack as if the wielder were fighting with two weapons (light weapon in the off hand).

A dragon is a reptilelike creature, usually winged, with magical or unusual abilities.

A class made up of characters who draw energy from the natural world to cast divine spells and gain special magical powers.

The player who portrays nonplayer characters, makes up the story setting for the other players, and serves as a referee. Also called DM.

Unconscious and near death. A dying character has -1 to -9 current hit points, can take no actions, and is unconscious. Each round on her turn, a dying character rolls d% to see whether she becomes stable. She has a 10% chance of becoming stable. If she does not, she loses 1 hit point. If a dying character reaches -10 hit points, she is dead.

This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane of Earth. Earth creatures usually have burrow speeds, and most earth creatures can burrow through solid rock.

This number represents a creature's overall power relative to that of a character from the Player's Handbook. A creature with an effective character level (ECL) of 10 is roughly equivalent to a 10th-level character. A creature's ECL is the sum of its Hit Dice (including class levels) and level adjustment. For instance, a splinterwaif has 2 HD and a +4 level adjustment. It is the equivalent of a 6th-level character.

Hit points gained through temporary increases in Constitution score. Unlike temporary hit points, points gained in this manner are not lost first, and must be subtracted from the character's current hit points at the time the Constitution increase ends.

Eladrins are a race of celestials, or good outsiders, native to the the Olympian Glades of Arborea.

A naturally occurring alloy of gold and silver.

One of the Inner Planes consisting almost entirely of one type of element: air, earth, fire, or water.

An elemental is a being composed of one of the four classical elements: air, earth, fire, or water.

The point in a combat round when all the participants have completed all their allowed actions. End of round occurs when no one else involved in the combat has an action pending for that round.

A creature unfriendly to you.

This supernatural ability bestows vital energy at a touch, and happens automatically when a melee or ranged attack hits. Each successful energy charge bestows one or more positive levels (the creature's description specifies how many) on living creatures. Unless otherwise specified in the creature's description, a draining creature loses 5 hit points for each positive level it bestows. A creature may not have more positive levels than its Constitution bonus (minimum 1).

Damage caused by one of five types of energy (not counting positive and negative energy): acid, cold, electricity, fire, and sonic.

This supernatural attack saps a living opponent's vital energy and happens automatically when a melee or ranged attack hits. Each successful energy drain bestows one or more negative levels (the creature's description specifies how many). If an attack that includes an energy drain scores a critical hit, it drains twice the given amount. Unless otherwise specified in the creature's description, a draining creature gains 5 temporary hit points (10 on a critical hit) for each negative level it bestows on an opponent. These temporary hit points last for a maximum of 1 hour.

The character gains one or more negative levels, which might permanently drain the character's levels.

An Inner Plane, either the Positive Energy Plane or the Negative Energy Plane.

Threatening or being threatened by an enemy. (Unconscious or otherwise immobilized characters are not considered engaged unless they are actually being attacked.)

A bonus that represents an increase in the sturdiness and/or effectiveness of armor or natural armor, or the effectiveness of a weapon, or a general bonus to an ability score. Multiple enhancement bonuses on the same object (in the case of armor and weapons), creature (in the case of natural armor), or ability score do not stack. Only the highest enhancement bonus applies. Since enhancement bonuses to armor or natural armor effectively increase the armor or natural armor's bonus to AC, they don't apply against touch attacks.

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 attack rolls and a -4 penalty to its effective Dexterity score. An entangled character who attempts to cast a spell must make a Concentration check (DC 15 + the spell's level) or lose the spell.

This entry in a statistics block describes the type of climate and terrain where the creature is typically found. This is a preference, but is not exclusionary. Note that these environments can also exist in portions of dungeons due to magical effects or other supernatural interference, or as features in dungeons or other environment areas.

On the Ethereal Plane. An ethereal creature is invisible, inaudible, insubstantial, and scentless to creatures on the Material Plane, but visible and corporeal to creatures on the Ethereal Plane. As such, such a creature is capable of moving through solid objects on the Material Plane and in any direction (even up or down), though all movement is at half speed. Most magical attacks have no effect on them. See invisibility and true seeing reveal ethereal creatures.

A gray, foggy plane parallel to the Material Plane at all points. Creatures within the Ethereal Plane can see and hear into the Material Plane to a distance of 60 feet, though the reverse is not usually true. Force effects originating on the Material Plane can affect items and creatures on the Ethereal Plane, but the reverse is not true. Because the Ethereal Plane is often used for travel, it is also considered a transitive plane (like the Astral Plane and the Plane of Shadow).

The evasion extraordinary ability allows the target of an area attack to leap or twist out of the way. Rogues and monks have evasion and improved evasion as class features, but certain other creatures have these abilities, too.

A subtype usually applied only to outsiders native to the evil-aligned Outer Planes. Evil outsiders are also called fiends. Most creatures that have this subtype also have evil alignments; however, if their alignments change, they still retain the subtype. Any effect that depends on alignment affects a creature with this subtype as if the creature has an evil alignment, no matter what its alignment actually is. The creature also suffers effects according to its actual alignment. A creature with the evil subtype overcomes damage reduction as if its natural weapons and any weapons it wields were evil-aligned.

Tired to the point of significant impairment. An exhausted character moves at half speed and takes a -6 penalty to Strength and Dexterity. After 1 hour of complete rest, an exhausted character becomes fatigued. A fatigued character becomes exhausted by doing something else that would normally cause fatigue.
