Polymorph Self

This spell allows the caster to change into a different form of living creature. The form assumed may not have more hit dice than the caster has levels, nor be incorporeal or gaseous. The caster assumes the physical nature of the assumed form while retaining their mental and spiritual characteristics. They gain the Armor Class and all physical attacks possessed by the form but do not gain any special, supernatural or spell-like abilities. Dragon breath is a special ability, for instance, so were the caster to assume the form of a dragon they could use the dragon's normal claw, bite, and tail swipe attacks, but not the dragon's breath. If the form assumed is capable of speaking and making appropriate gestures (as determined by the GM) the caster may use their own spells in the assumed form. Equipment worn or carried will be dropped if the new form is unable to wear or carry the items. If any such item would be constricting or physically harmful to the new form, the transformation slows and alters such that the item is dropped without damage to the items nor harm to the target creature. If the GM decides that any such item cannot be removed in this way, the spell fails. The caster can remain transformed up to one hour per level of ability, or may choose to end the spell before that point if they wish.
