Bafflement

2-level Enchantment

You must make eye contact with a target creature that you can see within range. As you speak to the creature, it must make a Wisdom saving throw. This spell is considered to have a charm effect for the purposes of how it affects creatures. On a failed save, the target can’t speak coherently for the duration, nor can it cast spells with verbal components.   An affected creature can make a new saving throw at the end of each of its turns, ending the spell on a success.
