What It Is

A reaction is a quick response to a trigger, often outside your own turn.

This page is a compact play reference. If a spell, feature, monster, item, or DM ruling gives a more specific instruction, use that specific instruction.

How To Use It

Use your reaction when a rule gives you a trigger, such as an opportunity attack or a readied action.

Limits And Rolls

  • You normally get one reaction per round.
  • After using it, you cannot use another reaction until the start of your next turn.
  • The triggering rule decides whether a roll is needed.
  • You only roll when the rule, DM, spell, item, or feature asks for a roll.
