Claw of the Bear
This minor magical item consists of a set of supple gauntlets which, upon mental command, extrude sharp, enchanted bear claws (the gauntlets save vs. attacks as soft metal).
Effect: While in humanoid form, a druid wearing these gauntlets has two attacks per round in melee combat. The gloves are +1 weapons, and each inflicts ld3+2 points of damage per strike. Additionally, a druid using these claws may climb trees with no chance of falling and may climb irregular stone surfaces such as mountains and mortared walls as a thief with a base 75% success rate, modified by race and dexterity.
