Derpy Teeth

This spell has the Hex tag. Choose a creature within range. The creature must make a Constitution saving throw against your spell save DC (a willing creature can choose to automatically fail). On a failed save, they grow either enormous buck teeth or have their teeth become blunt and derpy, and for the next 6d10 hours, any bite attacks made by that creature deal 1d6 bludgeoning damage (if they have a bite attack that normally does more, it is reduced to 1d6 and changed to bludgeoning. If the creature doesn’t normally deal more than improvised damage, it increases to 1d6).
