Terran Quake

You cause a large tremor in the ground within range. Each creature other than you in that area must make a Strength saving throw. On a failed save, a creature takes 1d10 bludgeoning damage and is prone until the tremor ends. If the ground in that area is loose earth or stone, it becomes difficult terrain until cleared, with each 5-foot-diameter portion requiring at least 2 minutes to clear by hand.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for each slot level above 5th.
