Blood Magic

Blood Magic (often referred to as BM) is a keystone passive skill that allows the character to spend life instead of mana to use skills. It also sets maximum mana to zero.

Mechanics
If taken with Eldritch Battery, your energy shield will continue to protect mana but will not be spent.

Skills that reserve mana will reserve life. The cost of skills is calculated normally, so reduced mana cost or reduced mana reservation modifiers will reduce the amount of life used. It is not possible to commit suicide through Blood Magic.

While you have Blood Magic, you are neither at full mana, nor low mana.

Location
Blood Magic is located in the bottom left corner of the tree. Taking Blood Magic is required to reach the two 10% life nodes and the keystone passive skill, Mortal Conviction.

Related unique items
These unique items have the modifier, which provides the same effect as this keystone. Taking the keystone in addition to equipping one of these items will impart no additional benefit.
