Garb of Hades
Similar in some ways to Daemonic Possession, Garb of Hades allows the necromancer to inhabit a recently dead body, leaving her own form in a torpor-like state. The body may have been dead for no longer than 30 minutes before the ritual begins. The caster dresses herself in the clothes the subject wore at the time of death (the ritual must be performed nude if the subject died that way). The caster spends two blood points and symbolically "breathes" into the corpse's mouth. At that point, the caster inhabits the corpse and reanimates it. While in the corpse, the caster has access to the subject's memories, though only those from the past several days and nights are clear. The caster may even access the subject's Abilities, though only one dot of each, regardless of the subject's original level of mastery. The magician does not gain access to the subject's supernatural abilities, if any (such as Disciplines, shapeshifting or other powers). The ritual lasts a number of scenes equal to the caster's successes when casting; after this time, the body rapidly decays and the caster returns to her own body.
