Reactions

Free Reactions: In addition to a Reaction, every creature also has a Free Reaction they can use.

The free object interaction each character has once per turn may be used as a Free Reaction instead, if there is a trigger that plausibly allows for such a reaction, at the DMs mercy. For example, you can use your Free Reaction to shut a door as soon as someone has walked through it on their turn.

When you have the Incapacitated condition, you can no longer use your Free Reaction.

Every feature that uses a Free Reaction can also use a Reaction instead.

Reserving Actions: At the end of your turn, you gain 1 additional Reaction per Action you did not use. If you were unable to use these Actions because you were Incapacitated, this conversion does not happen.

Ready Action: When using the Ready Action, you also gain 1 additional Reaction.

Reserving Bonus Actions: At the end of your turn, you gain 1 additional Reaction per Bonus Action you did not use. If you were unable to use these Bonus Actions because you were Incapacitated, this conversion does not happen.

Reserving Reactions: At the start your turn, you gain 1 Surge Die per Reaction you did not use. If you were unable to use these Reactions because you were Incapacitated, this conversion does not happen.

Reactive Defence: There are now options to reactively defend against incoming attacks and other effects. These include Dodging, Blocking and Parrying, as detailed within the Rules Glossary. For spellcasters, some of the new and reworked spells provide options for reactive defence.
