Vile Visage

You pull on the base instincts of a creature you can see within range to twist their features into what they revile most. The target must make a Charisma saving throw (the target can choose to fail this saving throw). On a failure, an illusion is applied to the target's face that reflects what the target considers ugly. The illusion does not change the creature's intrinsic characteristic such as race, but rather twists their own existing features into shapes that the target would deem ugly. For the duration, the target has -10 to all Charisma skill checks. A creature with an Intelligence score lower than 4 or a creature that lacks a concept of beauty or ugliness is immune to the effects of this spell.
