Bloodthirst

Bloodthirst is a passive skill in Diablo III, unlocked at level 24.

In-game
This effect stacks with the respective stat from items. Health Glove bonus is added to the amount regained per 1 Fury, not to the total healing per cast.

Development
Before the pre-expansion patch of Reaper of Souls, this skill was granting the Barbarian 3% Life Steal, empowering their ability to heal from damage even further. However, even with the massive 80% debuff in the Inferno difficulty setting, the sheer power of Life Steal in the hands of very powerful heroes, let alone Barbarians, proved too powerful for balancing reasons. As a result of this, Bloodthirst was reworked in the above-mentioned patch to offer Life for expending Fury, and it has remained this way since.
