Action Boost

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

Action boosts are available for Heroic character levels 1-20 as class enhancements for Artificers, Barbarians, Bards, Fighters, Paladins, Rangers and Rogues. Boosts are also available as race-restricted options for Humans, Half-Orcs, and Half-elves, as well as characters with Epic levels through an Epic Destiny, such as Legendary Dreadnought. These come in a variety of flavors each improving a different character stat including, but not limited to, attack speed, damage, saving throws, skill checks, and armor class. Characters can 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.


 * Action boosts can be used five times per rest (which is normally a shared pool for groups of action boosts). Some items (e.g. Action Boost Enhancement), classes, races and Epic Destinies have access to enhancements or Epic abilities that increase the number of uses per rest.

List of action boosts
The following list contains Action Boosts that are possessed by various classes, races, or Epic Destinies. Note that Type is not intended to reflect any in-game categorization of action boosts. Instead, it says if the action boost can be obtained by spending action points on a Class, a Racial, or a Universal enhancement tree, or spending destiny points on a Epic Destiny.

Abilities similar to action boosts
Some classes have abilities similar to action boosts, but they don't count as such. For example, effects that decrease the cooldown or increase the number of uses of action boosts are not applied to them.

Reaper Memento abilities
Reaper enhancements available for completing quests on Reaper difficulty offer a mechanic similar to Action Boosts, called Memento abilities. Mementos last for 30 seconds, they are on a 40-second cooldown, and they can be used simultaneously to Action Boost.

All Memento abilities share a single cooldown and a single shared pool of Reaper Charges. Each Memento you have at least one rank in grants an extra Reaper Charge.
