Testicular (Or Other Gender And Monstrous Means Of Reproduction) Torsion

One creature of your choice that you can see within reach feels a tightening in its nether region. The target makes a Constitution saving throw. On a failed save, it takes 3d6 Force damage and has the Incapacitated condition until the end of its next turn. On a successful save, the target takes half as much damage and is mildly discomforted but otherwise unaffected.

Targets with no known organs of reproduction are immune to this spell.

Using a Higher-Level Spell Slot. The damage increases by 1d6 for each spell slot level above 1.
