Blood Magic

Keystone

Removes all mana
10% more maximum Life
Skills Cost Life instead of Mana
Skills Reserve Life instead of Mana [1]

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 converts all mana cost and reservation to use life instead. It also gives you more maximum life and removes your mana.

Mechanics

Skills that reserve mana will reserve life and skills that cost mana will cost life instead. Mods that affect mana cost and mana reservation such as X% increased/reduced Mana Cost of Skills, + X to Total Mana Cost of Skills and X% increased/reduced Mana Reservation Efficiency of Skills have no effect on the life cost and life reservation of skills. It is not possible to commit suicide through Blood Magic.

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

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

Taking this keystone along with Sanguimancy from Warlock of the Mists will provide the 50% increased Life Reservation Efficiency of Skills stat, but otherwise impart no additional benefit.

Location

Blood Magic is located in the bottom left corner of the tree.
