Very thick, and fine wolf pelts that don't seem to wear out.   Built so the head fits over a helm, or head allowing the wearer to look thru the eyes of the pelt.    Upon wearing, wrapping themselves in, lying on, or lying under pelt transforms around player to turn them into a werewolf.   Use Werewolf from monster manual for game play.   If character was wearing armor the pelt fits over it, and is added to the werewolf character abilities.   Shields, treasures, and weapons ( other than spears ) are dropped to be left where they lay.     

Notes: Advantage: Ability Checks, Grappled, Charmed
