Arcane Blast

A burst of arcane force sweeps out from you. Each creature in a 20-foot sphere originating from you must make a Constitution saving throw. On a failed save, a creature takes 1d8 thunder damage, 1d8 fire damage, 1d8 cold damage, 1d8 force damage, and is knocked prone. On a successful save, the creature takes half as much damage and isn't knocked prone.

In addition, unsecured objects that are completely within the area of effect are automatically pushed 10 feet away from you by the spell's effect, and the spell emits bright light for 300 feet.

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