Playing the Game

While playing the Pathfinder RPG, the Game Master describes the events that occur in the game world, and the players take turns describing what their characters do in response to those events. Unlike storytelling, however, the actions of the players and the characters controlled by the Game Master (frequently called non-player characters, or NPCs) are not certain. Most actions require dice rolls to determine success, with some tasks being more difficult than others. Each character is better at some things than he is at other things, granting him bonuses based on his skills and abilities.

Whenever a roll is required, the roll is noted as “d#,” with the “#” representing the number of sides on the die. If you need to roll multiple dice of the same type, there will be a number before the “d.” For example, if you are required to roll 4d6, you should roll four six-sided dice and add the results together. Sometimes there will be a + or – after the notation, meaning that you add that number to, or subtract it from, the total results of the dice (not to each individual die rolled). Most die rolls in the game use a d20 with a number of modifiers based on the character's skills, his or her abilities, and the situation. Generally speaking, rolling high is better than rolling low. Percentile rolls are a special case, indicated as rolling d%. You can generate a random number in this range by rolling two differently colored ten-sided dice (2d10). Pick one color to represent the tens digit, then roll both dice. If the die chosen to be the tens digit rolls a “4” and the other d10 rolls a “2,” then you've generated a 42. A zero on the tens digit die indicates a result from 1 to 9, or 100 if both dice result in a zero. Some d10s are printed with “10,” “20,” “30,” and so on in order to make reading d% rolls easier. Unless otherwise noted, whenever you are must round a number, always round down.

As your character goes on adventures, he earns gold, magic items, and experience points. Gold can be used to purchase better equipment, while magic items possess powerful abilities that enhance your character. Experience points are awarded for overcoming challenges and completing major storylines. When your character has earned enough experience points, he increases his character level by one, granting him new powers and abilities that allow him to take on even greater challenges.

The Most Important Rule

The rules presented are here to help you breathe life into your characters and the world they explore. While they are designed to make your game easy and exciting, you might find that some of them do not suit the style of play that your gaming group enjoys. Remember that these rules are yours. You can change them to fit your needs. Most Game Masters have a number of “house rules” that they use in their games. The Game Master and players should always discuss any rules changes to make sure that everyone understands how the game will be played. Although the Game Master is the final arbiter of the rules, the Pathfinder RPG is a shared experience, and all of the players should contribute their thoughts when the rules are in doubt.

Common Terms

The Pathfinder RPG uses a number of terms, abbreviations, and definitions in presenting the rules of the game. The following are among the most common.

Ability Score: Each creature has six ability scores: Strength, Dexterity, Constitution, Intelligence, Wisdom, 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.

Caster Level (CL): 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 the caster's level.

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 NPC classes, which are less powerful (see Creating NPCs).

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

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).

Creature: A creature is an active participant in the story or world. This includes PCs, NPCs, and monsters.

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 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.

Level: A character's level represents his overall ability and power. There are three types of levels. Class level is the number of levels of a specific class possessed by a character. Character level is the sum of all of the levels possessed by a character in all of his classes. In addition, spells have a level associated with them numbered from 0 to 9. This level indicates the general power of the spell. As a spellcaster gains levels, he learns to cast spells of a higher level.

Monster: Monsters are creatures that rely on racial Hit Dice instead of class levels for their powers and abilities (although some possess class levels as well). PCs are usually not monsters.

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.

Nonplayer Character (NPC): These are characters controlled by the GM.

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.

Player Character (Character, PC): These are the characters portrayed by the players.

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.

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 character 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.

Generating a Character

From the sly rogue to the stalwart paladin, the Pathfinder RPG allows you to make the character you want to play. When generating a character, start with your character's concept. Do you want a character who goes toe-to-toe with terrible monsters, matching sword and shield against claws and fangs? Or do you want a mystical seer who draws his powers from the great beyond to further his own ends? Nearly anything is possible.

Once you have a general concept worked out, use the following steps to bring your idea to life, recording the resulting information and statistics on your Pathfinder RPG character sheet, which can be found at the back of this book and photocopied for your convenience.

Step 1—Determine Ability Scores: Start by generating your character's ability scores. These six scores determine your character's most basic attributes and are used to decide a wide variety of details and statistics. Some class selections require you to have better than average scores for some of your abilities.

Step 2—Pick Your Race: Next, pick your character's race, noting any modifiers to your ability scores and any other racial traits (see Races). There are seven basic races to choose from, although your GM might have others to add to the list. Each race lists the languages your character automatically knows, as well as a number of bonus languages. A character knows a number of additional bonus languages equal to his or her Intelligence modifier.

Step 3—Pick Your Class: A character's class represents a profession, such as fighter or wizard. If this is a new character, he starts at 1st level in his chosen class. As he gains experience points (XP) for defeating monsters, he goes up in level, granting him new powers and abilities.

Step 4—Pick Skills and Select Feats: Determine the number of skill ranks possessed by your character, based on his class and Intelligence modifier (and any other bonuses, such as the bonus received by humans). Then spend these ranks on skills, but remember that you cannot have more ranks than your level in any one skill (for a starting character, this is usually one). After skills, determine how many feats your character receives, based on his class and level, and select them from those presented in Feats.

Step 5—Buy Equipment: Each new character begins the game with an amount of gold, based on his class, that can be spent on a wide range of equipment and gear, from chainmail armor to leather backpacks. This gear helps your character survive while adventuring. Generally speaking, you cannot use this starting money to buy magic items without the consent of your GM.

Step 6—Finishing Details: Finally, you need to determine all of a character's details, including his starting hit points (hp), Armor Class (AC), saving throws, initiative modifier, and attack values. All of these numbers are determined by the decisions made in previous steps. Aside from these, you need to decide on your character's name, alignment, and physical appearance. It is best to jot down a few personality traits as well, to help you play the character during the game. Additional rules (like age and alignment) are described in Additional Rules.

Ability Scores

Each character has six ability scores that represent his character's most basic attributes. They are his raw talent and prowess. While a character rarely rolls an ability check (using just an ability score), these scores, and the modifiers they create, affect nearly every aspect of a character's skills and abilities. Each ability score generally ranges from 3 to 18, although racial bonuses and penalties can alter this; an average ability score is 10.

Generating Ability Scores

There are a number of different methods used to generate ability scores. Each of these methods gives a different level of flexibility and randomness to character generation.

Racial modifiers (adjustments made to your ability scores due to your character's race—see Races) are applied after the scores are generated.

Standard: Roll 4d6, discard the lowest die result, and add the three remaining results together. Record this total and repeat the process until six numbers are generated. Assign these totals to your ability scores as you see fit. This method is less random than Classic and tends to create characters with above-average ability scores.

Classic: Roll 3d6 and add the dice together. Record this total and repeat the process until you generate six numbers. Assign these results to your ability scores as you see fit. This method is quite random, and some characters will have clearly superior abilities. This randomness can be taken one step further, with the totals applied to specific ability scores in the order they are rolled. Characters generated using this method are difficult to fit to predetermined concepts, as their scores might not support given classes or personalities, and instead are best designed around their ability scores.

Heroic: Roll 2d6 and add 6 to the sum of the dice. Record this total and repeat the process until six numbers are generated. Assign these totals to your ability scores as you see fit. This is less random than the Standard method and generates characters with mostly above-average scores.

Dice Pool: Each character has a pool of 24d6 to assign to his statistics. Before the dice are rolled, the player selects the number of dice to roll for each score, with a minimum of 3d6 for each ability. Once the dice have been assigned, the player rolls each group and totals the result of the three highest dice. For more high-powered games, the GM should increase the total number of dice to 28. This method generates characters of a similar power to the Standard method.

Purchase: Each character receives a number of points to spend on increasing his basic attributes. In this method, all attributes start at a base of 10. A character can increase an individual score by spending some of his points. Likewise, he can gain more points to spend on other scores by decreasing one or more of his ability scores. No score can be reduced below 7 or raised above 18 using this method. See Table: Ability Score Costs for the costs of each score. After all the points are spent, apply any racial modifiers the character might have.

The number of points you have to spend using the purchase method depends on the type of campaign you are playing. The standard value for a character is 15 points. Average nonplayer characters (NPCs) are typically built using as few as 3 points. See Table: Ability Score Points for a number of possible point values depending on the style of campaign. The purchase method emphasizes player choice and creates equally balanced characters. This system is typically used for organized play events, such as the Pathfinder Society (visit paizo.com/pathfinderSociety for more details on this exciting campaign).

Determine Bonuses

Each ability, after changes made because of race, has a modifier ranging from –5 to +5. Table: Ability Modifiers and Bonus Spells shows the modifier for each score. The modifier is the number you apply to the die roll when your character tries to do something related to that ability. You also use the modifier with some numbers that aren't die rolls. A positive modifier is called a bonus, and a negative modifier is called a penalty. The table also shows bonus spells, which you'll need to know about if your character is a spellcaster.

Abilities and Spellcasters

The ability that governs bonus spells depends on what type of spellcaster your character is: Intelligence for wizards; Wisdom for clerics, druids, and rangers; and Charisma for bards, paladins, and sorcerers. In addition to having a high ability score, a spellcaster must be of a high enough class level to be able to cast spells of a given spell level. See the class descriptions in Classes for details.

The Abilities

Each ability partially describes your character and affects some of his actions.

Strength (Str)

Strength measures muscle and physical power. This ability is important for those who engage in hand-to-hand (or “melee”) combat, such as fighters, monks, paladins, and some rangers. Strength also sets the maximum amount of weight your character can carry. A character with a Strength score of 0 is too weak to move in any way and is unconscious. Some creatures do not possess a Strength score and have no modifier at all to Strength-based skills or checks.

You apply your character's Strength modifier to:

Dexterity (Dex)

Dexterity measures agility, reflexes, and balance. This ability is the most important one for rogues, but it's also useful for characters who wear light or medium armor or no armor at all. This ability is vital for characters seeking to excel with ranged weapons, such as the bow or sling. A character with a Dexterity score of 0 is incapable of moving and is effectively immobile (but not unconscious).

You apply your character's Dexterity modifier to:

Constitution (Con)

Constitution represents your character's health and stamina. A Constitution bonus increases a character's hit points, so the ability is important for all classes. Some creatures, such as undead and constructs, do not have a Constitution score. Their modifier is +0 for any Constitution-based checks. A character with a Constitution score of 0 is dead.

You apply your character's Constitution modifier to:

If a character's Constitution score changes enough to alter his or her Constitution modifier, the character's hit points also increase or decrease accordingly.

Intelligence (Int)

Intelligence determines how well your character learns and reasons. This ability is important for wizards because it affects their spellcasting ability in many ways. Creatures of animal-level instinct have Intelligence scores of 1 or 2. Any creature capable of understanding speech has a score of at least 3. A character with an Intelligence score of 0 is comatose. Some creatures do not possess an Intelligence score. Their modifier is +0 for any Intelligence-based skills or checks.

You apply your character's Intelligence modifier to:

A wizard gains bonus spells based on his Intelligence score. The minimum Intelligence score needed to cast a wizard spell is 10 + the spell's level.

Wisdom (Wis)

Wisdom describes a character's willpower, common sense, awareness, and intuition. Wisdom is the most important ability for clerics and druids, and it is also important for paladins and rangers. If you want your character to have acute senses, put a high score in Wisdom. Every creature has a Wisdom score. A character with a Wisdom score of 0 is incapable of rational thought and is unconscious.

You apply your character's Wisdom modifier to:

Clerics, druids, and rangers get bonus spells based on their Wisdom scores. The minimum Wisdom score needed to cast a cleric, druid, or ranger spell is 10 + the spell's level.

Charisma (Cha)

Charisma measures a character's personality, personal magnetism, ability to lead, and appearance. It is the most important ability for paladins, sorcerers, and bards. It is also important for clerics, since it affects their ability to channel energy. For undead creatures, Charisma is a measure of their unnatural “lifeforce.” Every creature has a Charisma score. A character with a Charisma score of 0 is not able to exert himself in any way and is unconscious.

You apply your character's Charisma modifier to:

Bards, paladins, and sorcerers gain a number of bonus spells based on their Charisma scores. The minimum Charisma score needed to cast a bard, paladin, or sorcerer spell is 10 + the spell's level.
