Force Nova (5e Spell)
From D&D Wiki
You stamp the ground beneath your feet and a burst of energy expands outwards. Each creature within range must make a Strength saving throw. On a failed save, a creature takes 6d6 force damage and is pushed up to 10 feet away from you and is knocked prone. On a successful save, a creature takes half as much damage and isn't pushed away from you or knocked prone.
If a creature is flying when you cast this spell they automatically fail the saving throw and they take an additional 1d6 force damage. A large creature that fails its save is only pushed half as far.
In addition, any unsecured objects within range when the spell is cast are pushed up to 10 feet away from you.
At Higher Levels. When you cast this spell using a spell slot of 4th Level or higher, the damage is increased by 1d6 for each spell slot above 3rd. When you cast this spell using a spell slot of 6th level or higher the distance a creature is pushed increases to 30 feet.
