Persona 6 shadows should have a kidney stone spell

You know how in persona games shadows use spells that mess you and your buddies up, like confusion spells or spells that make you scared, angry, sleepy, etc. They should give shadows a kidney stone spell. Think of how effective that would be for the shadows, healing spells wouldn't work on it too well because technically a kidney stone isn't wound or injury. It would be like hella painful or at least uncomfortable enough to mess up teammates in battle. Imagine the navi dialogue that could come from that kind of a spell!  COMEDY. FUCKING. GOLD.
