Arcane Sunder

You thrust arcane energy out from your hands to a distance of 30 feet in a 5 foot wide line. All creatures in the line must succeed on a Dexterity saving throw or take 2d8 force damage and are pushed to the side of your choice adjacent to the line. On a successful save, the creature takes half damage and is not pushed.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
