When the dark arts call for flesh, you can only trust your own.

Life Tap is a signature warlock spell that allows them to trade their health for mana - the primary resource consumed to use their abilities. Hearthstone's version of Life Tap is very similar, in this case trading health in exchange for the most vital resource of all - cards.

Life Tap is a signature warlock spell that converts health into mana. The mana restored is equal to 15% of the warlock's health.

Life Tap epitomises the character of the warlock, sacrificing a chunk of their own life in exchange for a rapid injection of power. This tradeoff can allow warlocks to produce an endless stream of damage and death - while their health holds.
