Arcane Barrage

You create two large glowing bursts of violent force, sending them to a single enemy target within the range. The two intertwine, striking the target and creating an explosion of force, dealing 8d4+8 force damage to the target. All creatures within a 10-foot radius sphere of the target must succeed on a Strength saving throw or be pushed away from the center of the blast 5 feet.

At higher levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d4 for each slot level above 4th.
