Tenser's Swipe

You cause a massive spectral blade to appear in your hand and you swipe outwards in a massive arc. Make a melee spell attack against each creature of your choice in a 15 foot cone, dealing 4d6 force damage on hit.

 At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, you deal an additional 1d6 force damage per spell level above 2nd.
