Overpower

Overpower is a Might skill.

In-game
When invoked, the Barbarian instantly calls forth a bolt from above to strike at his/her location, dealing Physical damage to all nearby enemies.

Overpower is an instantaneous cast, and can be used on the move, in the middle of another attack, or even in certain situations where normally attacking is not possible.

As of patch 2.4.3, it is one of the seven skills in game (along with Sentry, Dashing Strike,, Blood Rush with Metabolism rune, Avalanche with Tectonic Rift rune and Furious Charge with Dreadnought rune) that uses Charge system, allowing multiple casts to be performed at once using accumulated charges. The charge replenishment time is reduced by cooldown reduction.
