Cerebral Cauterisation

Believed by many fanatics to be the only cure for madness, you reach into the target's psyche, blasting it with merciful fire. Make a melee spell attack against the target. On hit, the target takes 2d6 fire damage and 2d6 phychic damage. If the target is under the effects of any spell from the enchantment or illusion schools, or other mind-controlling effects, it can immediately make any relevant saving throw against that spell. If the target is maintaining concentration on a spell, any Concentration check it makes due to damage from this spell is made with disadvantage.
