Ethereal Dagger Storm

Ethereal daggers fall from the sky in a 20-foot-radius, 40-foot-high cylinder centered on a point within range. Each creature in the cylinder must make a Dexterity saving throw. A creature takes 2d8 piercing damage and 4d6 force 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 5th level or higher, the piercing damage increases by 1d8 for each slot level above 4th.
