This spell allows the caster to change and modify the target's body with minute and skilled precision. The caster can change just about anything about them; add/remove wings, add new appendages, body armor, or even a complete gender change! The spell works even better than a skilled xixchil surgeon could ever hope to do. This spell is not fullproof, however, as it has a 50% minus 2% per level of the caster chance of backlashing on the caster. The victim gets a saving throw vs. spells to avoid the effect. The victim also, if the save is failed, must save vs. death magic or go insane. The DM may judge if this is necessary. If the recipient willingly underwent the change, he gains a +3 bonus to the insanity roll and gets no save to avoid the change.

The changes are limited by the imagination of the caster and the opinion at the DM. The change can only be reversed with a Wish or this spell again. The material component is a piece of chameleon skin and the brain of a mimic.
