Hit point

Hit points are an abstraction for the amount of damage a monster or player can take before dying. When an attack succeeds, some number of hit points (determined by the type of attack and a random number) are deducted from the target's remaining supply. Losing hit points has little effect (other than on the player's face in the status bar) until a target reaches zero hit points, at which point it dies.

Barrels also have hit points, exploding when they reach zero.
