Arial mask bug

THIS MASK: a black and white tragi-comedy mask can be referred to as 'black white tragi-comedy mask'. It is worth 0 copper, and is of the 30th level of power. It is armor worn on face. It is made of bone and weighs 2 kg 700 g. When worn, it protects you against piercing for 8, bashing for 8, slashing for 8, magic for 8, and the elements for 8 points each. When worn, it affects your save vs mental by -10 points and your charisma by 3 points. CANNOT BE WORN BY AN ARIAL: That will not fit your avian features. EVEN THOUGH THE GUY IT COMES FROM: Your best guess is that he is an arial. You could kill the tragi-comedy masked Stagemaster with your little finger. The tragi-comedy masked Stagemaster is about the same size you are. He greets you warmly. THANKS!
