Bloodthirst is a simple skill, if you were to look at it through the [[WarCraft 3II]] (or [http://starcraft.incgamers.com/wiki/DotA DotA]) perspective, you would understand this skill as a 30% [[lifesteal]] for 10 seconds. In Diablo 2 most skills didn't give life per hit, but there were health [[leech]]ing prefixes on weapons, which could make any class gain health on hits. This skill is aimed to make the Barbarian less worried about health during battles, and should probably be taken as soon as possible if the player wishing to make tanking a breeze. It can be assumed that other skills which deal damage will also bring in health.
