Vacuum Vortex

You reach a grasping hand towards a space of your choice within range. The moment you close your grasp you cause the designated space to collapse onto a point. Each creature in a 20-foot-radius sphere centered on that point must make a Strenght saving throw. A target takes 8d6 force damage on a failed save, or half as much damage on a successful one.

Creatures that fail the saving throw are drawn to the center of the vortex and are knocked prove when the spell ends. 

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
