Chant of Resurrection

The Chant of Resurrection was an immensely powerful and sinister spell used to temporarily reanimate the dead. Of magick origin, it manifested as a greenish mist channeled from or through a glowing orb/crystalline object and was required to be spoken in a special language. Though powerful, the spell's effects would last only as long as the caster was active; should they cease maintaining it or be killed whilst using the spell, the undead would become immobile corpses once more.
