This forbidden form of magic allows the users to revive the souls of the dead within the bodies of the living. This magic also requires a large amount of mana and a sacrifice. Red tattoos appear on the faces of those who are possessed when the reincarnated souls are in control, and the designs change as the reincarnated souls' holds on their bodies become more solidified. These tattoos do not always disappear when the spell is removed.
Reincarnated souls are afflicted by wicked hearts 「邪心 jashin」, which magnify negative emotions, like hatred and despair. In elves, this increases the likelihood of them turning into dark elves.
If a soul has undergone two reincarnation spells, it will retain possession of a soulless body when the Reincarnation Magic is dispelled.
