Demonic Icicle

You select a creature you can see and form a volley of demonic icicles above the target. The icicles come crashing down to strike the foe and everything around it in a 5-foot cube. The creatures within the square must make a Dexterity saving throw. A target takes 3d4 cold 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 3th level or higher, the damage increases by 1d4 and the range by 5 feet for each slot level above 3rd.
