Action Economy
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.
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 Reactions: At the start of 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 below. The Dodge Action has been adjusted accordingly, and a more general Defence Action has been introduced to focus on reactive defence. For spellcasters, some of the new and reworked spells provide options for reactive defence.
