This wand has 5 charges. While holding it, you can use an action to expend 1 of its charges to cast the polymorph spell (save DC 15) from it.
The wand regains 1d4 + 1 expended charges daily at dawn. If you expend the wand's last charge, roll a d20. On a 1, the wand crumbles into ashes and is destroyed. Immediately after you cast a spell using this wand or use a charge you have to roll a d20, If you roll a 1, roll on the Wild Magic Surge table to create a magical effect. If you succeed the number goes up by one each time you succeed.
