When this spell is cast, the wizard can alter his appearance and form - including clothing and equipment - to appear taller or shorter; thin, fat, or in between; human, humanoid, or any other generally man-shaped bipedal creature.
The caster's body can undergo a limited physical alteration and his size can be changed up to 50%. If the form selected has wings, the wizard can actually fly, but at only one-third the speed of a true creature of that type, and with a loss of two maneuverability classes (to a minimum of E).
If the form has gills, the caster can breathe under water as long as the spell lasts. However, the caster does not gain any multiple attack routines or additional damage allowed to an assumed form.
The caster's attack rolls, Armor Class, and saving throws do not change. The spell does not confer spoecial abilities, attack forms, or defenses. Once the new form is chosen, it remains for the duration of the spell.
The caster can change back into his own form at will; this ends the spell immediately.
A caster who is slain automatically returns to his normal form.
