Unending Penis Barrage

Each creature in a 10-foot radius, 70-foot-high cylinder centered on a point within range must make a Dexterity saving throw. A creature takes 3d4 bludgeoning and 3d4 piercing damage on a failed save, or half as much damage on a successful one. On each of your turns until the spell ends, you can use your action to call move the cylinder 30ft. If you do not use your action to move the cylinder in this way, the spell ends leaving a yogurt like substance on the floor of the last place it covered. That area is difficult terrain for 1 round, the substance then disappears.

At Higher Levels. When you cast this spell using a spell slot of 4th or higher level, the damage increases by 1d4 bludgeoning and 1d4 piercing for each slot level above 3rd.
