Trait Inversion

When you use this spell the victim has to succeed a DC 13 charisma save and it the save succeeds the nothing happens to the targed but if they fail the saving throw it cause’s there best & worst traits to flip. Let’s say you use this spell on a wizard who has a 16 in intelligence and an 8 in strength. Well, after this spell is used on that wizard they now have a 8 in intelligence and a strength score of 16. This could be really funny to use on the main villain of the game. You can use this spell on the person again to switch them back to normal.
