Wand of Smiles

The Saving Throw DC for your Enchantment
school spells is increased by 1.
This wand also has 3 charges. You can expend 1
of its charges and target a humanoid you can see
within 30ft. The target must succeed on a DC10
Charisma Saving Throw or be forced to smile for
1 minute.
The wand regains all expended charges at dawn.
When you spend the last charge, roll a d20. On a
1, inform the DM.
