Noh Mask of the Shapech anger

Wondrous item, uncommon (requires attunement)

Each of the hundreds of kinds of noh masks of the shapechanger is keyed to a specific transmutation spell and the mask itself is carved from cypress wood in the shape of a specific creature whose form can be assumed by the mask’s keyed spell. The spell and creature are chosen by the mask’s creator and cannot be changed. While the mask is worn, the wearer can transform into the specific creature depicted by the mask for up to 5 minutes per day, functioning as the mask’s keyed spell. These minutes don’t need to be consecutive, but they must be spent in 1-minute increments.

When transforming into a creature using a noh mask of the shapechanger, the wearer transforms into a generic creature of the mask’s kind with the exact features depicted by the mask. If the mask has particularly outlandish features, it allows the wearer to add their proficiency bonus as if it were a disguise kit to any ability checks made to impersonate a specific creature of that kind. If the wearer possesses the Wild Shape ability, she can use Wild Shape to transform into the specific creature depicted by the mask instead of one of her usual Wild Shape choices.

The creator of a noh mask of the shapechanger can spend an additional 1,250 gp in special pigments mixed with a piece of an individual creature’s body in order to paint the mask with a perfect recreation of that individual creature’s face; this requires a DC 20 Dexterity check. If the check is successful, the mask perfectly resembles that individual creature, allowing the wearer to use the noh mask to transform into that individual creature instead of a generic creature of the mask’s kind. This choice must be made when the noh mask of the shapechanger is first created.
