Take the Body
This spell is, to the best of anyone’s knowledge, known only to two people : Iuchiban and Yajinden. They have guarded its secrets carefully and so far no other maho-tsukai has ever exhibited its power. The spell allows the caster to literally "leap" his soul into the body of another person within range, instantly and permanently taking their body as his own. The caster must succeed in a Contested Willpower roll against the victim, and if the victim wins, the caster is hurled back into his current body.
