Action Boost

Action boosts increase some aspect of a character's abilities for a short period of time.

Action boosts are available for Heroic character levels 1-20 as class enhancements for Artificers, Barbarians, Fighters, Paladins, Rangers and Rogues. Boosts are also available as race-restricted options for Humans and Half-elves, as well as characters with Epic levels through an Epic Destiny, such as Legendary Dreadnought.

Action boosts come in a variety of flavors each improving a different character ability including, but not limited to, attack speed, damage, saving throws, skill checks, and armor class.

Characters gain access to action boosts by spending action points on enhancements or destiny points in Epic Destinies.

Limitations
Action boosts typically last 20 seconds with a 30-second shared cooldown between uses. There are a few exceptions, such as Kensei's Power Surge. Racial action boosts used to be on a separate cooldown; this anomaly was removed in Update 34.

Action boosts can be used five times per rest. Some items, classes, races and Epic Destinies have access to enhancements or Epic abilities that increase the number of uses per rest.
