Dog-Bone Knife

The blade of this +1 striking dagger is made from the thigh bone of a canine that died in the act of protecting its master. A werecreature or other creature willingly under the effects of a non-permanent polymorph effect damaged by a dog-bone knife must succeed at a DC 19 will save or immediately revert to its natural form-this has no effect on a creature unwillingly polymorphed. On a successful save, the creature is temporarily immune to this effect for 1 minute. Kushtakas and other creatures vulnerable to canines take a -2 circumstance penalty to saves against this effect, and this weapon overcomes any resistance such creatures have to physical attacks.
