Unholy Storm

Spell created by M.T. Black of DMs Guild.

Until the spell ends, globs of solid shadow fall in a 20-foot-tall cylinder with a 40-foot radius centered on a point you choose within range. The area becomes lightly obscured, and all ranged attacks made by creatures within the spell’s area or made against those creatures, are made with disadvantage.

Each creature that starts its turn in the cylinder must make a Dexterity saving throw. A creature takes 2d6 bludgeoning damage and 2d6 necrotic damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the amount of necrotic damage increases by 1d6 for each slot level above 3rd.
