The item is a yellow opal amulet ringed with incredibly tough wood set on a mithral necklace chain. If detect magic is cast on the item it will appear to be magical. When the amulet is worn, the wearer can speak its command word and act as if polymorph had been cast on him, except rolling a d20 and becoming the result from the list below. The effect will last for 24 hours and can only be dispelled prematurely for the first hour, requiring the full spell period to be waited before the spell ends after the first hour. If the amulet is worn without casting the spell for 1 hour or more, the wearer must make a DC 10 Constitution saving throw. On a failed save, roll a d20 and consult the random effects list. When the amulet is removed, the random effects will stop growing on the user, and they will slowly turn back to normal over the course of 1d4+2 days
