Beastmask

The caster or one willing creature they touch is made to look, feel, sound, and smell exactly like a particular species of aberration, beast, dragon, or monstrosity that has an Intelligence of 4 or lower - but only to members of that species. These will treat the target as they would normally treat another member of their species.

Members of closely related species are also fooled, provided those creature have an Intelligence of 4 or less. For instance, a dog mask will also fool wolves and death-hounds, while a bear mask will fool dire bears and owlbears.
