Unmask

This spell creates a stationary area in which the caster can see all creatures as they truly are. The spell affects all those within a 30-foot cube, except the caster. The spell overcomes disguises, including the effects of polymorph spells, change self, illusions, and appearances caused by items such as a hat of difference. Only the caster sees the target creatures' true appearances. Others see the creatures as their illusions or spells show them to be. (However, certain magics creating a lasting and permanent change are not subject to this effect.)

The caster can center the unmask spell up to 10 feet away for each level of experience (for example, a 5th-level caster can center the spell up to 50 feet away):

The material component of the spell is a black piece of cloth with two eyeholes cut in it.

Notes: Rare spell (WoG). Believed to have originated in the Valley of the Mage.
