Blood Magic

Blood Magic is a magic-based mod made by WayofTime. Blood Magic adds an expansive life-based magic system which spans rituals, sacrifices, summoning, alchemy and spell creation. In Blood Magic, you collect Life Essence by sacrificing your own health or the health of mobs that can be used to power your Blood Magic creations on your quest to become an Archmage. Blood Magic has even more capabilities if Technomancy or Thaumcraft 4 are installed.
