You catch foes off guard when changing your shape.
Benefit(s): Whenever you use your change shape ability to assume a new form or to return to your true form, you can attempt a Bluff check as a swift action to feint one opponent within 30 feet who witnessed your transformation. You take a –4 penalty on Bluff checks to feint an opponent who is aware that you are a shapechanger. You don’t take the usual penalties for feinting a creature of a different type or a creature with an Intelligence score of 1 or 2 when feinting in this manner.
Special: A character with the wild shape class feature counts as having the change shape ability and shapechanger subtype for the purpose of meeting this feat’s prerequisites. A character with wild shape can use this feat’s benefit whenever she uses wild shape to assume a new form or return to her true form.
