Arcane Explosion

As an Action, you may expend a 2nd-level spell slot to release an explosion of pure arcane energy. Each creature of your choice in a 3m radius centered around you must make a Dexterity Saving Throw. A creature takes 2d8 Force damage on a failed save and is pushed 3m away from you. On a successful save, the creature takes half as much damage and isn't pushed. In addition, unsecured objects that are within the area of effect are automatically pushed 3m away from you by the spell's effect.

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.
