Compelled Joke

You channel your wit and comedic genius through your magic to force someone else to tell a joke. As an action, you can choose a creature that you can see within 60 feet of you to make a Charisma saving throw. On a failure, they take 3d6 psychic damage as their mind fails to complete the joke, imposing disadvantage on its next spell or weapon attack they make. On a successful save, the creature takes half the amount of damage and does not gain disadvantage, instead gaining advantage if it makes another creature within 60 feet of it laugh as they somehow manage to finish the joke. A creature with an Intelligence score below 5 is unaffected by this spell.
