Hybrid Form Feat 5Kitsune Source Ancestry Guide pg. 124 2.0PFS Note Characters with hybrid form can retain elements of their kitsune form when they use Change Shape, but they do not have to (they can still change fully into their alternative form).
When you
Change Shape, you retain elements of your kitsune form, allowing you to speak in a fox form, use kitsune unarmed attacks in a tailless form, or gain a tail in your tailless form to use abilities that require one. You can Change Shape to alter the details of your hybrid form without fully changing into your true form or your alternate form. While in hybrid form, your foxlike features make it obvious that you aren't a normal humanoid.
Traits
