Bridge of the World of the Living and the Dead

creates an intense connection between the material plane and the astral plane, reviving all dead that have remaining corpses, and preventing death in the material plane. Those with very small amounts of a corpse instead come back as ghosts. The spell stays active as long as held, up to a maximum of one minute. At the end of the spell, all undead return to the astral plane unless they are under the effect of "Turn Undead", and death can once more occur on the material plane. As an added effect, spellcasters marked with the blood used to cast the spell learn "Turn Undead" as a cantrip and do not need to roll to successfully turn an undead.
