Testicular Torsion

You reach out as if grabbing a soft small object in your palm, and twist your hand.

On a successful Constitution saving throw nothing happens except the target feels a something caress their balls. On an unsuccessful Constitution saving throw the creature targeted goes prone for 5 minutes also dealing 2d6 + your spellcasting modifier, and on a 1 loses their balls.

(The creature targeted must have male genitalia)
