A 20 foot-radius sphere of crushing force forms at a point you can see within range and tugs at the creatures there. Each creature in the sphere must make a Constitution saving throw. On a failed save, the creature takes 5*D10 force damage and is pulled in a straight line toward the center of the sphere, ending in an unoccupied space as close to the center as possible (even if that space is in the air). On a successful save, the creature takes half as much damage and is not pulled.
This is a Dunamancy spell and it should be discussed beforehand with your DM.
