Bone Club

A wizard can use this spell to enchant a bone, causing it to become a magical club. This magical weapon acts as a club +4 against undead, inflicting 5-10 (1d6 +4) hit points of damage, and a club +1 against all other opponents, inflicting 2-7 (1d6 + 1) hit points of damage. The bone can be from any animal, providing the bone normally could be wielded as a club; for instance, a human femur could be enchanted by this spell, but a skull could not. At the end of the spell's duration, the bone club reverts to a normal bone.   Characters with a weapon proficiency with a club also have a proficiency with a bone club. Those wielding a bone club without the club proficiency suffer attack penalties.
