Veilstrike

You recreate your own fist from the essence of the Astral Plane at a point within range and smash nearby foes to the ground. Each creature within a 20-foot radius, 20ft high cylinder must make a dexterity saving throw. On a failed save, a creature takes 5d10 force damage and is knocked prone. On a successful save, the creature takes half damage and isn’t knocked prone.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d10 for each slot level above 4th.
