Godgraft (Curses, Cost, Per Scenario, Corrupting): The caster rolls INT/Clever +2 to graft one or more divine organs, tissue, or body parts onto a willing subject. The subject must lose some of their own substance and essence to create space(s) for the graft(s) to fit, so amputations, flensing, and organ removal usually occurs prior to to casting. The recipient crosses off an existing Aspect and creates a new one representing the graft.
The recipient typically agrees to the casting because of the prospect of acquiring divine powers or abilities. The recipient rolls 1DF. On a positive roll, the GM determines what beneficial power has been acquired; on negative roll, some deleterious change occurs in the recipient as a result of the graft; on a zero (0) result, the limb, organ, or tissue is simply a functional replacement for the organ that was removed.
For the caster, this is a Major or Severe Infraction, depending on the deity and organs involved.
This spell is inspired by Michael Moorcock's Corum series.
