Flailing Maelstrom

A wave of heavy braided chains whirl out around you. Each creature in a 15-foot cube originating from you must make a Strength saving throw. On a failed save, a creature takes 2d8 magical bludgeoning damage and is pushed 10 ft away from you. On a successful save, the creature takes half as much damage and isn't pushed.

In addition, unsecured objects that are completely within the area of effect are automatically pushed 10 ft 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, the damage increases by 1d8 for each slot level above 1st
