## 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. | Reaction | Source<br>(Who can do this?) | Trigger | Notes | | --------------------------------------------------- | ------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------- | | [[03-Mechanics/9-Combat Maneuvers/Unending Wheel/Expert Sidestep (2 points)]] | Unending Wheel combat tradition | Creature makes a weapon attack against you | AC bonus equal to your [[Proficiency Bonus]] | | [Fall Back](https://a5e.tools/rules/actions-combat) | Anyone | Foe uses [Press the Attack](https://a5e.tools/rules/actions-combat) bonus action against you, and you're not raging | Move back 5', removes expertise from Press The Attack | | [[03-Mechanics/9-Combat Maneuvers/Razor's Edge/Iron Will (1 point)]] | Razor's Edge combat tradition | You make a [saving throw](https://a5e.tools/rules/saving-throw "Click to view a local node.") to resist being [charmed](https://a5e.tools/rules/conditions "Click to view a local node.") or [frightened](https://a5e.tools/rules/conditions "Click to view a local node.") | Gain [advantage](https://a5e.tools/node/130 "Click to view a local node.") on the saving throw. | | [[Opportunity Attacks]] | Anyone | Creature leaves a space you threaten | Make a melee weapon attack against it | | [[Sacrifice Shield]] | Anyone using a shield | When you take a critical hit | Block the crit and take a regular hit:<br> - Lose magic bonuses to shield<br> - Non-magical shields become [broken](https://a5e.tools/rules/maintenance) | | [[01-A5E/3 Classes/Marshal/Marshal#Spur Ally\|Spur Ally]] | Marshals | **Once daily:** An ally you can see who can hear or see you fails fails an [[Ability Scores, Skills, Checks, Saving Throws\|ability check]] **(does not include attack rolls)** or *saving throw* | **Ally can reroll** the check |
