Shifting Faces

FEAT 5

Prerequisites tailless alternate form

Frequency once per day

You wear many faces, even those that don't belong to you. When you Change Shape into your tailless form, you gain the effects of 3rd-rank Illusory Disguise for 1 hour or until you shift back, except it's a transmutation effect rather than an illusion.
