Awful Joke

Awful Joke
Cantrip Enchantment (All Classes)
Casting time: 1 action
Range: Self
Components: Vocal
Duration: Instantaneous

You tell an awful, horrible joke that's so bad it causes pain. Any living creature that can hear and understand you in a 20-foot sphere around you must make an Intelligence saving throw, if they succeed, they take 1d8 psychic damage and are unable to take reactions until the end of their next turn while they question their meaning in life. If they fail the saving throw, they didn't catch the joke and nothing happens to them.
The damage increases by 1d8 at level 5, 11, and 17.

(You can still make 'normal' awful jokes, but in order for them to do that much damage, you must first tell everyone that you are going to cast Awful Joke. The only difference is that a 'normal' awful joke only causes 1 hit point of psychic damage)
