Abilites are representations of a creature's physical and mental attributes. There are six abilities in Baldur's Gate 3, and every creature has a set of six ability scores, numerical values which repdesent how well they perform at each ability.

Each ability score translate directly into an ability score modifier – modifiers which function as bonuses or penalties that are added to most dice rolls in the game.

Overview

The six abilities each represent an aspect of a creature' capabilities:

Ability scores are bought with points during character creation. The minimum ability score during character creation is 8, and the maximum is 15, before any of the ability score increases are applied.

Ability score modifiers

Each ability has an ability score modifier, which is derived from its ability score, that add their ability score modifiers to any ability checks, saving throws and attack rolls they make associated with that ability, as well as to the Difficulty Class (DC) of any spells that they cast.

Creatures also add an ability score modifier to initiative rolls and some damage rolls they make, and some features allow creatures to add additional or alternative ability score modifiers to specific rolls.

An ability's modifier is decreased by 1 for every odd score below 10, and is increased by 1 for every even score above 10.[note 1]

Ability checks

Ability checks are dice rolls made to determine whether a creature succeeds or fails at a task. When attempting an ability check, a creature rolls a d20, and then adds the relevant ability score modifier and, if applicable, proficiency bonus to the results of the roll. If the final results equal or exceeds a target Difficulty Class (DC), specific to that task, it is considered as success.

Formula: D20.png d20 + Ability Score Modifier + (when applicable) proficiency Bonus

Skills

Ability checks are usually made using a specified skill. Skills are specific areas of expertise, each associated with an ability, that characters can be proficient in.[note 2]

Character add their proficiency bonus to any ability checks they make using skills they are proficient in.

All characters gain proficiency in two skills based on their chosen background during character creation, and can choose 2-4 more skills to be proficient in from a list of skills determined by their class.

Additionally, some races, subclasses and feats also give proficiency in specific skills, and bards receive the class feature Jack of All Trades Jack of All Trades at level 2, allowing them to add half their proficiency bonus to ability checks they make using skills they are not proficient in.

Expertise

Characters can also have expertise in a skill, which allows them to add double their proficiency bonus:

  • Rogues gain expertise in two skills they are proficient in at both level 1 and level 6.
  • Bards gain expertise in two skills they are proficient in at both level 3 and level 10
  • Knowledge Domain clerics gain expertise in two skills, from a choice of Arcana, History, Nature and Religion, at level 1.
  • The Actor feat gives expertise in Deception and Performance.
  • Gnome#Rock gnomes have both expertise in History.

Multiple sources of skill proficiency

Neither proficiency nor expertise stack: there is no special benefit to having multiple sources of proficiency on a single character, nor is there any benefit to having both proficiency and expertise at the same time. Some sources of expertise do, however, require the character to already be proficient in a skill in order to gain expertise in it.

Common scenarios

Automatic rolls

Some ability checks are automatic. For example, when a creature approaches an unactivated trap, the game rolls a Perception ability check to determine whether the creation notices the trap. Perception is a Wisdom Skill, so the character adds their Wisdom modifier and, if proficient in Perception, their proficiency bonus to the ability check. Once the trap is discovered, the character can interact with it to attempt to Disarm it, which requires a successful Sleight of Hand check, a Dexterity Skill.

During dialogue

Ability checks are also common during dialogue, where some responses require a ability check to determine the outcome. Examples include using Charisma-based skills like Persuasion, Deception or Intimidation to influence others, or Intelligence-based Skills like Investigation, History or Religion to determine or remember facts.

Contests

A contest is a special type of ability check in which two creatures both roll an ability check to oppose each other, and one wins over the other. The creatures don't necessarily roll the same type of check.

An example of this is the Shove Shove action. The creature attempting the Shove rolls Athletics, and the defending creature rolls either Athletics or Acrobatics (the game chooses the Skill with the highest bonus) to contest the Shove. If the attacker's roll is higher than the defender's, the Shove succeeds; otherwise it fails.

Saving throws

See also: Saving throws

Each saving throw has an associated ability, and creatures can have proficiency with or advantage on saves that use a specific ability, usually granted by class and race, respectively.

  • Dexterity is a common ability used for saves against spells that deal area of effect damage, often halving the damage rolls of those spells.
  • Constitution saves are used is used to maintain concentration on long-duration spells, and are used when saving against poisons or spells that test a target's endurance or resilience.
  • Intelligence saves are used against psionic spells and features, such as those used by illithids.
  • Wisdom is a commonly used ability for saves against spells that test a creature's composure, willpower or self control.

Interactions with classes

Each class has designated primary and secondary abilities. While these have no particular mechanical significance, they are mentioned in the character creator, and serve as recommendations for players unfamiliar with the rules of the game.

Classes do however frequently have features that rely on abilities.

Spellcasting ability

For more information, see Spellcasting ability and proficiency.

Every class has an spellcasting ability whose modifier they add to the attack rolls and save DCs of their known spells.[note 3][note 4]

Intelligence
Fighter, Rogue, Wizard.
Wisdom
Cleric, Druid, Monk, Ranger.
Charisma
Barbarian, Bard, Paladin, Sorcerer, Warlock.

Spells from sources other than class instead use the spellcasting ability of the class the caster most recently took a first level in.

Ability score reduction

Some supernatural or magical effects (like Devour Intellect) can temporarily drain abilities, reducing one or more of the target's ability scores, potentially to zero. If any score is reduced to zero, the target dies instantly.

Footnotes

  1. Ability score modifiera cannot be increased beyond +10, even if their respective ability scores are increased further.
  2. Ability checks made using skills are often referred to as skill checks by the community, although they are not referred to as such in-game.
  3. The primary ability of casters classes always corresponds to their spellcasting ability, with the exception of rangers and classes that gain spellcasting via a subclass class feature.
  4. Racial spells may use their own designated ability. For example, the cantrip granted during character creation by the elf or half-elf race always uses Intelligence, regardless of the creature's class.
  5. 5.0 5.1 The Mirror of Loss can both permanently improve and temporarily reduce ability scores.
