Taran's Terrible Tossup

Choose one target creature you can see within range. Roll a d6. On a one, the target must make a Strength saving throw, on a two a Dexterity saving throw, on a three a Constitution saving throw, on a four an Intelligence saving throw, on a five a Wisdom saving throw, and on a six a Charisma saving throw. On a failure, the target must use the corresponding stat for their weapon attack rolls or spell attack rolls and saves, replacing the stat they usually use. At the end of their turn, the target may roll a d6 and try to make a save against your spell save dc using the corresponding stat, ending the effects of the spell on a success.
