Arcane Explosion

Unleash a wave of raw arcane energy in a 10 foot radius sphere with you as the point of origin. Every creature wholly within the sphere’s radius(except you) makes a Strength saving throw. On a failed save they take 1d8 Force damage and are pushed back 10 feet. On a successful save they take half damage, rounded down, and are pushed back 5 feet.

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.

At Higher Levels: When you cast this spell using a spell slot of 2nd level or higher, add an additional 1d8 per level above 1st.
