Blade Bombard

You punch a creature you can see within you reach. You momentarily disappear, and the target must make a dexterity saving throw. On a failed save, the target takes 10d8 force damage and is knocked prone as spectral slashes rend the air around it. On a successful save, the target takes half as much damage and isn't knocked prone. You reappear directly after the spell ends.

At Higher Levels: When you cast this spell using a spell slot of 6th level or higher, the damage increases by 2d8, and the target is knocked back 5 feet for each spell level above 5th.
