Damage/Effect: Bludgeoning
A dozen giant, spectral fists appear and pummel creatures, structures, and objects in a 10-foot cube centered on a point you can see within range. Each creature in the area must make a Strength saving throw, taking 10d6 bludgeoning damage on a failed save, or half as much damage on a successful one. A creature made of inorganic material such as stone, crystal, or metal has disadvantage on this saving throw.
Any nonmagical structure and any nonmagical object that isn’t being worn or carried also takes the damage if it’s in the spell’s area.
At higher levels: When you cast this spell using a spell slot of 6th level or higher, the size of the cube increases by 5 feet for each slot level above 5th.
