Bamboo muzzle

This is a small piece of bamboo that can be tied around someone's mouth by using one action. When worn this muzzle gives the wearer a base 20 strength and speed count but only allows the use of one attack. While wearing the muzzle a being can extend and sharpen their fingernails (if the creature already has them) and scratch entities in a five foot radius. Scratching a creature deals 5d 10 slashing damage. while wearing the muzzle a creature cannot use any means of communication ( unless the communication does not require speech) and automatically fails all intimidation, persuasion, and other verbal checks.
