borrowing and modifying from the doppelganger:
Change Shape (Su): Yash'Mortis can assume the shape of any humanoid. In humanoid form, Yash'Mortis loses his natural attacks. Yash'Mortis can remain in a humanoid form until he chooses to assume a new one. A change in form cannot be dispelled, nor does Yash'Mortis revert to his natural form when killed. A true seeing spell or ability reveals his natural form.
