Crumple

You compress an object or creature within range into a space five times smaller than what it took up before. Any creature being compressed must make a strength saving throw, taking 1d8 force damage on a success or 1d12 force damage on a failure. 

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 (success) or 1d12 (failure) for each slot level above 5th.
