Stoneburst (5e Spell)
From D&D Wiki
|Casting time:||1 action|
Choose a mass of stone or earth you can see within range. You displace the chosen earth or stone in an area up to a 10-foot cube, the displaced fountain of churned earth or stone erupting in a direction of your choice, filling an adjacent 10-foot cube with rubble.
Each creature in either area must make a Dexterity saving throw. A creature takes 10d6 bludgeoning damage on a failed save, or half as much damage on a successful one. Any creature in the first cube that fails its saving throw is also flung into the area of the second cube.
Additionally, the ground in that area becomes difficult terrain until cleared away. Each 5-foot-square portion of the area requires at least 1 minute to clear by hand.
At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the area of both cubes increases by 10 feet for each slot level above 4th.
