A focus bar begins at full with one hundred points and begins to deplete as focus-consuming moves are performed. Some hunter abilities restore focus, such as and . A hunter's focus regenerates at a rate of six focus per second and a pet's focus regenerates at a rate of five focus per second. This rate is not effected by being in or out of combat or other features like gear or player level. Focus is increased by 10/20/30% for each talent point spent on the talent.
Hunters played with focus during the early stages of the development of World of Warcraft. At that point, Focus only regenerated when standing still. This distinguishing feature of hunters was dropped before launch, and the developers had hunters use mana instead(like always). Focus was reintroduced with the release of Cataclysm.
