Erupting Filth

Choose a point you can see on the ground within range. This spell’s transformative energies cause a fountain of rotting flesh and vegetable matter to erupt in a 20-foot cube centered on that point. Each creature in that area must make a Dexterity saving throw. A creature takes 3d12 necrotic damage on a failed save, or half as much damage on a successful one. Additionally, a creature which fails the saving throw automatically contracts sewer plague (see chapter 8, Diseases, DMG).

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d12 for each slot level above 3rd.
