Ability Score Modifier
An Ability Score Modifier is a Die Roll modifier based on an Ability Score of a creature. It can affect every type of roll. Depending on the Ability Score in question, it can be shortened to Strength Modifier, Dexterity Modifier, Constitution Modifier, and so on.
When it's applied[edit | edit source]
Attack Roll[edit | edit source]
For a spell that uses an Attack Roll, the Ability Score to be used depends on the Class of the creature casting the spell. For example, a Wizard uses Intelligence, a Cleric uses Wisdom, and a Sorcerer uses Charisma. See the Attack Roll page for details.
Damage Roll[edit | edit source]
For spells, the Ability Score Modifier is normally not used, though there are exceptions. For example, the class feature Agonising Blast allows a Warlock to add their Charisma Modifier to the damage of Eldritch Blast; and the spell Shillelagh imbues a weapon with magic, such that it benefits from the wielder's Wisdom Modifier.
Saving Throw[edit | edit source]
Each Saving Throw is tied to a certain Ability Score, which determines its type, such as Strength Saving Throw, Dexterity Saving Throw, and so on, which determines the Ability Score Modifier that will be used.
Ability Check[edit | edit source]
A special type of Ability Check is the Skill Check, where a specific skill like Athletics, Perception, Sleight of Hand, etc. is used, but each Skill maps to a corresponding Ability Score, so the Ability Score Modifier still applies. For example, Athletics is based on Strength, whereas Sleight of Hand is based on Dexterity.
Value[edit | edit source]
Following is the table for the Ability Score Modifier value based on how high the corresponding Ability Score of a creature is:
