Transmutation [Judicial Curse]
For a sorcerer, the loss of her natural powers can be a fate worse than death. As a result, this ritual is not undertaken lightly. It involves a lengthy incantation and the creation of a complex mystical seal around the victim, so she must be unconscious, restrained, or a willing participant in the ritual. In addition to the materials required by the spell, you must have the cooperation of at least two assistants; as they are a required part of the spell, these first two assistants do not provide you with a point of ceremonial force.
The spell takes an hour; at the end of this time you must spend 500 XP and your target must make a Will save. If she’s successful, the spell fails. If she fails to make her save, she loses the ability to cast any form of arcane magic for as long as the spell remains in effect. You have the power to restore her abilities at any time; otherwise, she can only regain her mystical abilities as a result of a limited wish, miracle, or wish.
Material Component: The gemstone powder and mystic oils used to create the seal cost 500 gp. These are used up in the casting; if the target saves against the effect and you wish to try again, you must use new components.
XP Cost: 500 XP
