Shape of the Beast (3.5e Maneuver)

''This form is not the only one you own. Inside you're a monster, let them see the truth.''

This maneuver duplicates the effects of polymorph, except you can only take on the forms of creatures of the Animal and Magical Beast types. You may continue to use maneuvers, but may be limited due to inability to speak, lack of hands, or other gross changes. You do not regain hit points as if you had rested for the night when changing form, nor does your own type change.

This maneuver is a supernatural ability. It requires access to natural or magical shapeshifting.
