Wand of Frowns

This wand has 3 charges. While holding it, you can use an action to expend one of its charges and target a humanoid you can see within 30 feet. The target must succeed on a DC10 Charisma saving throw or be forced to scowl for one minute. The wand regains all expended charges daily at dawn. If you expend the wand's last charge, roll a d20. On a 1, it transforms into a Wand of Smiles.
