Wolf Hair Shirt

Wondrous item, uncommon (requires attunement)

When you don this shirt you cannot be perceived by wolves, dogs, or other canine animals; they treat you as if you did not exist. If you touch a wolf, dog, or other canine or attacks any creature, the protection of the wolf-hair shirt is lost for 1 hour. Werewolves and canine monstrosities must succeed on a DC 12 Wisdom saving throw to notice you. In addition to the above, any spell or innate spell you use to assume the form of a canine animal or magical beast grants one additional hit die to your form.
