A destructive wave of force sweeps out from you. Each creature within a 15-foot cube aside from the caster must make a Constitution saving throw. On a failed save, a creature takes 2d8 force damage and is thrown 10 feet away from you. On a successful save, the creature takes half as much damage and isn't thrown. 

In addition, unsecured objects that are entirely within the blast radius are thrown 10 feet away from you. This spell emits a loud boom akin to an explosion that is audible up to 300 feet away from you.

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