Spirit is a resource used by the Monk in Diablo III.

To defeat the inhuman evils they pit themselves against, monks draw upon inner reserves of Spirit, a resource that reflects their personal mastery and training.

Spirit replenishes slowly. It is generated in two ways – by specific skills and attacks, and by the completion of combos. Monks who chain their attacks carefully can continue a near-endless barrage of Spirit-fueled strikes.

Spirit is a valuable resource, but massive expenditures of this force allow a monk to call upon potent dodges and defensive moves, as well as monster-slaying finishing strikes. Thanks to monks' physical perfection and martial talent, they are free to deliver as many empowered strikes as their Spirit pools will allow – without waiting for ability 'cooldowns'.
