Dioga Gravidon

You summon multicolored vacuum sickles swirling in a spiraling torrent of crushing gravitational force and launch them in a 60-foot line that is 10 feet wide. Each creature in the line must make a Dexterity saving throw. On a failed save, a creature takes 8d10 force damage and is knocked prone as the sickles slice through and slam them into the ground. On a successful save, the creature takes half damage and isn’t knocked prone. Unsecured objects in the line are shredded or pulled violently along with the sickles. At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d10 for each slot level above 5th.
