Dull

You mutter arcane words and drop the pearl into the vial of mercury, as you do so choose one creature within range. This creature must make a wisdom saving throw. If they should fail, the creature suffers agonizing pain in their head as mercury consumes the pearl, their Intelligence, Wisdom and Charisma are reduced to 1. They no longer recognize friend or foe, cannot communicate and cannot defend themselves. Effectively becoming husks of their former self. They can follow simple commands as well as eat and maintain themselves on a basic level but have no semblance of a personality or will. If a spell or magical effect would cause a creature to be charmed, they automatically fail any saving throws required.

This spell may be ended by greater restoration if it has been under 24 hours since the spell was first cast. Afterward only a Wish may restore the creature to their former self.
