Custom Blood Magic: Ritual

Made similarly to a blasphemy shrine, this shrine holds a victim to distill the Ab (soul) of the target into a series of Milks of Set.  This shrine is created with a living or torpid body.  If used on a torpid body, the ritual holds the victim in torpor until its Ab is distilled, at which point the ritual ends and the body is reduced to ash.  This ritual fails if the victim has undergone religious burial rites of any culture.  Milks of Set distilled from Imprisonment Shrines have a normal shelf life, but bodies in Imprisonment Shrines are preserved until their Abs are completely distilled. The caster may only have one Imprisonment Shrine in existence at a time.  Each Milk of Set distilled permanently strips at least one Willpower Trait from the victim.  When the body has lost the last of its Willpower Traits, it is reduced to ash and becomes useless for any further magical purposes. The imprisonment shrine only works vampires and mortals (and ghouls). Other supernatural creatures cannot be utilized.
