When this spell is cast, the shukenja is able to assume the form of any creature – from a small bird up to a great horse. There is no system shock, but the polymorphed shukenja gains only the form and its locomotion, not any special attacks, magical abilities, and so on. The shukenja can change from one form to another (takes half a round) as often as desired during the spell's duration. Damage to the polymorphed form is suffered by the shukenja but, upon return to human form, 1d12 hit points are restored.
Notes: Common for oriental priests; otherwise, very rare.
