Protection from lycanthropy

Protection from lycanthropy is a sorcerer/wizard spell that grants the target a greater chance to resist contracting lycanthropy when struck by a lycanthrope.

Effects
If already infected, the target has a chance to resist a shapechange. The spell's material component is lycanthrope blood and the chance of this protection increases if the blood is from the same type of lycanthrope as the attacker, and increases yet further if the blood is from the attacker itself.

History
This spell was created by Avan Vatsisen and it is likely that nobody else will have access to it..
