Mordenkainen's Defense Against Lycanthropes

This spell will aid a creature in surviving attacks made by lycanthropes. Any attack made upon the creature by a lycanthrope has a -2 penalty to hit. No matter how much damage a lycanthrope inflicts, the wounded creature will not contract lycanthropy as long as the spell is in effect. The spell will not protect the creature from contracting lycanthropy if injuries occur before the spell is cast or after it expires.

The material component is crushed moonstone worth at least 30 gp.

Notes: Uncommon or rare spell (WoG).
