This Numen allows the spirit to Claim a dead body as other spirits would Claim a living being. The body’s Soul is not Claimed, however, meaning that a contested roll is not necessary, the spirit simply spends three Essence points and Claims the body automatically during the course of a single hour. The host’s attributes increase as normal, but at a drastically accelerated rate: the Claimed gains points at a rate of one per hour instead of one per week, This power comes at a price, however; while most Claimed can last for years, if not centuries, the corpse is not so lucky — once it achieves full synthesis with its Riding spirit, the corpse begins to deteriorate, losing one Attribute point every three days as the spirit power consumes the body. Once any of its Physical Attributes reach 0, the body disintegrates, shunting the spirit and the body’s soul (if present) into the Shadow Realm. Fortunately, this fate is typically a theoretical one; most such spirits have completed their business long before such a fate becomes an issue.
