Testicular Torsion

Necromantic energy washes over a creature of your choice that you can see within range, rotating one of his testicles. The target must make a Constitution saving throw. The target takes 8d8 necrotic damage on a failed save, or half as much damage on a successful one. This spell has no effect on undead, constructs or female creatures.

If you target a creature that already failed the saving throw against this spell in the last 24 hours, it makes the saving throw with disadvantage, and the spell deals maximum damage to it.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d8 for each slot level above 4th.
