Mask of Wind
A skilled shugenja can petition the kami to create incredibly elaborate illusions to obscure one's identity and appearance. You may use this spell to adopt the appearance of any humanoid creature of approximately the same size, up to one foot taller or shorter than you. You could use this spell to assume the guise of a kenku, for example, because they roughly the same size as humans. A goblin or an ogre would be impossible, however, because they are too short and too large, respectively.
