## Reactions
Reactions can be used on another creature's turn, so **always be prepared to use your reactions**. Reactions have specific conditions that can occur at any time and you don’t want to let a golden opportunity escape your grasp. Most creatures and characters only have a single reaction per combat round, which resets at the start of its turn.
