'''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 are notated with a ''d'' followed by the number of sides on that specific die: {{DieIcon|d4|Force}} d4, {{DieIcon|d6|Radiant}} d6, {{DieIcon|d8|Cold}} d8, {{DieIcon|d10|Poison}} d10, {{DieIcon|d12|Psychic}} d12 and {{D20}}.
== 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|d6|Radiant}} d6
* {{DieIcon|d8|Cold}} d8
* {{DieIcon|d10|Poison}} d10
* {{DieIcon|d12|Psychic}} d12
* {{D20}}}


== Mechanics ==
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}}.
Dice rolls are abbreviated by specifying the number of dice rolled, followed by the size of the dice (how many sides it has), and finally, any applicable modifiers.


When a a single twenty sided die (d20) is rolled with no modifiers, it is abbreviated as {{InfoBlob|1d20}}.
Any applicable modifiers are then added to the final sum and results of the roll:
 
When two six-sided dice (d6) are rolled with a modifier of +2, the roll is abbreviated as {{InfoBlob|2d6+2}}.
 
The final result of a dice roll is determined by adding together the results of all the dice rolled, plus any applicable modifiers:
* Most rolls have an associated ability, and add a creature's respective [[ability score modifier]] to the result 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 rolls allow a creature to add its [[proficiency bonus]] to the results of the roll.

The range of results is usually given in parentheses. For example, a single dart from a {{SAI|Magic Missile}} 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.
 
=== 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 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 {{advantage}} or {{disadvantage}} on 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.
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.

Line 32: Line 43:
A creature with both advantage and disadvantage on a roll only rolls a single die, even if it has multiple instances of either.

== Rolls using d20 ==
===  
When a creature rolls dice to determine success, they roll a twenty-sided die ({{D20}}) and add the associated ability score modifier to the result of the roll. If applicable, they also add their proficiency bonus and appropriate modifiers from other sources. If the final result equals or exceeds a threshold value, it is considered a success.
