You target a creature and speak to them. Your arcane words befuddle them, causing their words to fall short as they begin to babble.
The target can't cast spells that require verbal components. Creatures that are immune to charm are not effected.
You lock eyes, arcane glyphs glowing around your mouth as you speak. A shadowy mist envelops the target, their tongue twists unnaturally, words falter into incoherent babble, disrupting their ability to cast verbal spells.
