Attack rolls

Core rule

Attack rolls

An attack roll decides whether an attack hits. The total must meet or exceed the target’s Armour Class.

Stage 1 · Combat basicsAttacks and dice

Roll a d20 and add the applicable ability modifier, proficiency bonus, and other attack bonuses. The weapon or spell determines which ability applies.

Damage is calculated after the hit is decided. A larger attack-roll total does not itself deal more damage.

A d20 has twenty possible results, from 1 to 20. It is used to resolve attacks and many uncertain actions.

Add the relevant ability modifier, proficiency, and other bonuses to the die. Meeting the target number is enough to succeed.

Attack rolls, saving throws, and ability checks use different bonuses. A bonus to one does not automatically apply to the others.
