Void Wave

From the palm of your hand you create a wave of damage that can knock creatures of your choosing back up to 10 ft. On a failed save they are knocked back 10 ft and take 2d8 force damage. On successful save only take half damage and they aren’t knocked back.

At Higher Levels: when spell is cast using a second level spell slot or above, damage is increased by 1d8 and knock back is increased by 5 feet per level above first.
