Blood Magic
Keystone Passive Skill

  • Removes all mana.
  • Spend Life instead of Mana for Skills
Lay open your veins, and draw power from your own spilled life.

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

Skills that reserve mana will reserve life when linked with this gem. 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.


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 notable passive skill, Mortal Conviction.

Item modifiers

These unique items have the Blood Magic 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.
