'''Dice rolls''' are an important mechanic in [[Baldur's Gate 3]] which determine the outcome of many different situations. For example, determining whether a character will succeed or not at using a particular skill, or if an attack will land and how much damage it will do. | |||
'''Dice rolls''' are | |||
== Overview == | |||
== | Whenever a creature attempts something that requires them to roll dice, the game automatically rolls either a single 20-sided die or one or multiple four, six, eight, ten or twelve-sided dice, each die notated with a ''d'' followed by the number of sides on that specific die: {{hlist| | ||
* {{DieIcon|d4|Force}} d4 | * {{DieIcon|d4|Force}} d4 | ||
* {{DieIcon|d6|Radiant}} d6 | * {{DieIcon|d6|Radiant}} d6 | ||
Line 13: | Line 13: | ||
* {{DieIcon|d10|Poison}} d10 | * {{DieIcon|d10|Poison}} d10 | ||
* {{DieIcon|d12|Psychic}} d12 | * {{DieIcon|d12|Psychic}} d12 | ||
* {{D20}}} | * {{D20}}} | ||
The number of dice rolled is notated by with a number placed immediately before the ''d'' – when a single twenty sided die (d20) is rolled with no modifiers, it is abbreviated as {{InfoBlob|1d20}}, when two six-sided dice (d6) are rolled with a modifier of +2, the roll is abbreviated as {{InfoBlob|2d6+2}}. | |||
Any applicable modifiers are then added to the final sum and results of the roll: | |||
* Most rolls have an associated ability, and add a creature's respective [[ability score modifier]] to the result of the roll. | |||
* Some rolls allow a creature to add its [[proficiency bonus]] to the results of the roll. | |||
* Some equipment, [[spells]], [[conditions]], [[potions]] and [[class]] features can add a modifier to specific types of rolls. | |||
* Certain environmental effects or circumstances add a modifier to specific types of rolls. | |||
Modifiers may be negative, in which case they may be referred to as penalties. | |||
The range of results is usually given in parentheses. For example, a single dart from a {{SAI|Magic Missile|h=20px}} spell does 1d4+1 (2-5) Force damage, meaning it rolls 1d4 and adds 1 to the result, giving a possible total of between 2 and 5 points of damage. | |||
=== d20 rolls === | |||
d20 rolls are generally rolled against a number – ypically an [[Armour Class]] (A) or [[Difficulty Class]] (DC) – to determine success. If the final result of the roll, after any applicable modifiers are added, is equal to or exceeds the number it is rolled against, the attempt was successful. | |||
=== Unique mechanics === | |||
A number of gameplay mechanics apply only to d20 rolls. | |||
A | |||
=== Natural 1s and 20s === | === Natural 1s and 20s === | ||
Rolling a 1 or 20 on a d20 roll is referred to as a ''natural 1'' or ''natural 20''. When making an attack roll or ability check, rolling a natural | Rolling a 1 or 20 on a d20 roll is referred to as a ''natural 1'' or ''natural 20''. When making an attack roll or ability check, rolling a natural one is always an automatic failure, while a natural twenty is always an automatic success, regardless of the the final result after modifiers are applied. Saving throws attempted during dialogue and death saving throws can also roll roll natural 1s and 20s. | ||
=== Advantage and disadvantage === | === Advantage and disadvantage === | ||
A creature may have [File:Advantage Icon|20px]] or [File:Disadvantage Icon|20px]] a d20 roll. A creature with either rolls twice (depicted in the game as two dice rolled simultaneously) and uses the higher result if they have advantage, or the lower result for disadvantage. | |||
Advantage and disadvantage do not stack. If multiple instances of advantage or disadvantage apply to a roll, a creature still only rolls twice. | |||
A creature with both advantage and disadvantage on a roll only rolls a single die, even if it has multiple instances of either. | |||
=== | === | ||
=== Attack rolls === | |||
When a creature attacks another, they usually make an attack roll. Attack rolls are made against the target's [[Armour Class]] (AC). If the final result of the attack roll is equal to or exceeds the target's AC, the outcome is a ''hit''. Otherwise, it is considered a ''miss''. | |||
{{ | Attack rolls are always required for [[weapons]] and [[Unarmed Strike|unarmed strikes]], and some spells, such as {{SAI|Fire Bolt}} and {{SAI|Eldritch Blast}}, also rely on attack rolls. | ||
Melee attacks generally use the creature's Strength modifier, and ranged attacks use Dexterity, or Strength for thrown weapons. Weapons with the Finesse property use whichever of those two modifiers is highest. Spellcasters use their [[Spells#Spellcasting_Ability_and_Proficiency|spellcasting ability modifier]] for attacks made with spells. Some magical effects, like the spell {{SAI|Shillelagh}} or a Warlock's {{SAI|Pact of the Blade}}, allow spellcasters to use their spellcasting modifier for weapon attack and damage rolls. | |||
A creature's proficiency bonus is added to attack rolls made with weapons they are proficient with. Classes capable of spellcasting add their proficiency bonus to the attack rolls of spells they cast. | |||
When an Attack is determined to be a hit, the creature rolls for damage. | |||
==== | ==== Critical hits ==== | ||
[[File: | [[File:critical hit.png|right|thumb|Example of a Critical Hit with a 1d6 Shortsword. The damage dice are doubled, but the Dexterity modifier is not.]] | ||
A natural 20 on an attack roll is a [[Critical hit|critical hit]]. In addition to being an automatic hit, the creature rolls twice the normal number of dice to determine damage, including additional dice such as those from smites or combat manoeuvres. "Flat" damage bonuses that add a fixed number are not doubled by a critical hit; this includes ability score modifiers, weapon enhancement bonuses and features and abilities like {{SAI|Great Weapon Master: All In}}. | |||
Some equipment, feats and class features (notably the {{class|Champion}}'s {{SAI|Improved Critical Hit}}) allow a creature to score a critical hit on natural rolls of 19 or 20, or even 18 to 20. The benefits are the same as for a regular critical hit. | |||
=== Saving throws === | |||
Traps, spells, conditions and other sources of harm may allow a creature a chance to avoid or reduce their effect, known as a [[saving throw]] or ''save''. This is a d20 roll, with the relevant Ability and Difficulty Class (DC) determined by the source of the effect. If the final result of the roll equals or exceeds the DC, the save is successful. | |||
A creature can be proficient in saving throws on a per-ability basis. Player characters are proficient in two saving throws, based on their class. Proficency adds a creature's [[proficiency bonus]] to the saving throw. | |||
Traps, dialogue events and other sources of danger controlled by the game have a DC defined by the game, depending on how serious the danger is. Spells and [[Weapon Actions|weapon actions]] use specific formulas to determine the DC: | |||
* Spell saves have a DC determined by the creature's spellcasting Ability modifier: | |||
<div style="text-align: center;">Difficulty Class = {{InfoBlob|8 + [[Proficiency|Proficiency Bonus]] + [[#Spellcasting Ability and Proficiency|Spellcasting Ability Modifier]]}}</div> | |||
* Weapon actions saves have a DC determined by the higher of a creature's Dexterity or Strength, plus an inherent bonus for that specific action: | |||
<div style="text-align: center;">Difficulty Class = {{InfoBlob|10 + [[Strength|Strength]] or [[Dexterity|Dexterity]] + [[Weapon Actions#Melee Weapons|Inherent Weapon Action Bonus DC]]}}</div> | |||
Unlike attacks, saving throws are not guaranteed to fail or succeed when the d20 result is either a natural 1 or 20 respectively, however when saving throws are used during dialogue they will guarantee failure or success when a 1 or 20 is rolled. | |||
Saving | ==== Effect of success ==== | ||
A successful save can mean completely avoiding negative effects, reducing the damage received (usually by half), or both. For example, successfully saving against a spike trap could mean that a creature takes no damage at all, because it successfully evaded the spikes. On the other hand, if it's caught in the area of effect of a {{SAI|Fireball}}, then a successful save will merely halve the damage. Saving against {{SAI|Thunderwave}} both halves the damage taken, and prevents a creature from being pushed by the spell. | |||
Some effects don't allow a saving throw, for example the spell {{SAI|Sleep}}. | |||
=== | ==== Death saves ==== | ||
When a player character is {{cond|Downed}}, they make a special [[Death Saving Throw]] each turn to determine if they slip closer to death. Death saves are not associated with an Ability Score and so don't add any modifiers or the proficiency bonus. They only benefit from bonuses that apply to all saving throws (such as {{SAI|Bless}}) or specifically to death saves. | |||
Death saves are a success on a result of 10 or higher, and otherwise a failure. A character dies when three failures are accumulated, or becomes Stable (they no longer make death saves) when three successes are accumulated, whichever happens first. | |||
=== | === Ability checks === | ||
{{hatnote|See also [[Abilities#Ability checks|Ability checks]] in the [[Abilities]] article}} | |||
An ability check is an attempt to succeed at a specific task, and is rolled against a Difficulty Class (DC) set by the game for that task. If the final result of the roll equals or exceeds the DC, the attempt is successful. | |||
Ability checks can be triggered by player actions or dialogue choices, or they may be automatic, rolled by the game in the background in response to a trigger in the environment. | |||
Most ability checks have an associated [[Skills|skill]]. These rolls are often referred to as "skill checks" by the community, although they are not referred to as such in-game. If a creature is proficient with an ability check's associated skill, they may add their proficiency bonus to the results of the roll, in addition to the relevant ability score modifier. Characters with [[Expertise]] in a skill add double their proficiency bonus (shown in the interface as separate Proficiency and Expertise bonuses). | |||
Some ability checks are based only on the base Ability Score. A common example is exerting willpower to use the Tadpole's influence on other characters during dialogue. Checks like this have no applicable proficiency, and never add a proficiency bonus. | |||
=== Other d20 rolls === | |||
When a {{class|Wild Magic Sorcerer}} casts a leveled spell, a d20 is rolled to determine if they will trigger a [[Wild Magic (passive feature)|Wild Magic]] Surge. A surge is triggered only when the outcome is 20. The resulting effect, and {{Class|Wild Magic Barbarian}} surge effects for [[Rage: Wild Magic]], are also determined with dice rolls. | |||
== Damage rolls == | |||
{{hatnote|See also: [[Damage mechanics]].}} | |||
[[Damage rolls]] are used in the calculation of damage dealt by [[weapons]], [[spells]] and certain special abilities. They use one or more {{DieIcon|d4|Force}} d4s, {{DieIcon|d6|Radiant}} d6s, {{DieIcon|d8|Cold}} d8s, {{DieIcon|d10|Poison}} d10s or {{DieIcon|d12|Psychic}} d12s, adding any relevant modifiers to the result. | |||
== | |||
{{ | |||
Damage rolls always have an associated [[damage type]]. For example, a [[Daggers|dagger]] typically deals {{DamageText|1d4|Piercing}} damage. | |||
Damage rolled after a successful attack with a weapon typically adds the same ability score modifier as the attack roll, but some equipment, spells and class features bypass this. | |||
Damage rolled after a successful attack with a spell generally does not add a modifier, but might depending on the spell, the caster's class, and certain class features. For example, the {{class|Warlock}}'s {{SAI|Agonising Blast}} invocation allows the warlock to add its Charisma modifier to the damage rolls of the {{SAI|Eldritch Blast}} [[cantrip]]. | |||
Magic items, especially weapons, frequently add bonuses to damage, either as additional dice or flat modifiers. Many class features, feats and other effects can increase damage as well, and some (such as {{SAI|Ray of Enfeeblement}}) can reduce damage as well. | |||
=== | === Healing rolls === | ||
[[ | [[Healing]] restores a target's [[hit points]] but otherwise works similarly to damage rolls. Healing rolls may also add modifiers, but there's no general rule for this; any bonuses are determined by the source of the healing. For example, a [[Potion of Healing]] restores {{DamageText|2d4+2|Healing}}. There are many magic items, class features and other effects which also provide bonuses to healing, for example the {{Class|Life Domain}}'s {{SAI|Disciple of Life}} feature. | ||
== Rolling for initiative == | |||
When combat starts, all combatants roll for [[Initiative|initiative]] to determine the turn order. This is a d4 roll ([[D&D 5e rule changes|a significant departure from the tabletop rules]]), and adds a creature's Dexterity modifier. Proficiency does not apply, but some items, class features and other special abilities may provide bonuses. | |||
Creatures with the highest rolls act first. Allied player-controlled characters next to each other in the Initiative order effectively act simultaneously; the player can switch between them to coordinate their actions, and the game waits until all such characters have ended their turns to move on to the next non-player creature. | |||
