The ground beneath you starts to spiral into a hole that you begin to sink into. After you are enveloped into the earth, you are launched out of the ground 100 ft. in the direction that you were facing before you were submerged. You must make a Strength saving throw. On a failed save, you take 1d8 bludgeoning from the landing. 

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the amount of targets you can bring with you increases by 1 per spell level.
