Warning: The information on this page might be inaccurate due to a game update. If you know any information on this page to be in error, please fix it by clicking the edit link above.   If you can verify that all the information on this page has been updated correctly, please edit this page and remove this template. Reason: Several enhancements and Epic Destiny trees have been changed through game updates. However, not all the information on each Action Boost in this page has been updated accordingly.

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.
