You cause the forces of gravity in an area centered around a point you choose to become particularly intense. All creatures in this area must make a strength saving throw. On a failed save, a creature takes 5d4 force damage and is knocked prone while a creature takes half damage on a successful save and isn't knocked prone. If a creature's strength score is lower than your spell save DC, then they are unable to fly or use the dash action while they are in the area. Structures take twice as much damage from this spell, and if this would cause them to collapse the GM can decide the mechanics of how it would work.
