Later, she found that any kind of rotten cheese and sour wine would suffice as spell components. The caster must break the jar, releasing a sickening vapour that quickly wafts through the area of effect. All creatures within the area, who fail a saving throw vs. polymorph, are then transformed into ugly mockeries of themselves. Facial features become warped and bestial. Limbs become gnarled, stunted or ungainly.
Skin grows slimy scales or disgusting boils.
Even clothing becomes faded, moth-eaten, and garish. Other physical traits, attack and defence forms, special abilities, or mental attributes are otherwise unaffected, but the psychological shock of the transformation is often damage enough. The caster can end the spell before its duration, and the spell can also be dispelled normally. Natural shapeshifters are affected only for one round, and can then resume their normal form.
