UwU-ify

You blow glitter at a single creature within 10 feet, that you can see. The target must make a Charisma saving throw. On a failure, the target speaks in UwU-speak for the next 10 minutes and cannot preform the verbal component of any spell, as the UwU-speak makes this component impossible. The target may repeat this saving throw each time it takes damage. If the target does not speak any languages the spell fails automatically.  Whether or not the spell succeeds, the target knows you tried to cast the spell on them.
