Black Hole

You create a 1 foot  black sphere within range that sucks any living creature into it (including undead and constructs). Each creature except you that is within the radius must make a STR saving throw. on a failed save the targets are sucked all the way to sphere, take 35 (10d6) force damage and be knocked prone or be sucked only half way to the sphere, take half that damage and not be knocked prone on a successful one. If more than 1 target is being sucked all the way to the sphere, you add non-magical bludgeoning damage in addition to the force damage due to a collision between them. The bludgeoning damage added to the total is determined by the creature's size. This spell has no effect on creatures with immunity to magical force damage.

Tiny: 2 (1d4) Small: 3 (1d6) Medium: 6 (1d12) Large: 14 (4d6) Huge: 19 (3d12) Gargantuan: 28 (8d6)

 If the target is a fiend, celestial, elemental or fey and failed the saving throw, it must make a CHA saving throw in addition to the STR saving throw or be teleported to a random point in the astral plane for 1d4 days on a failed save and by the end of this time come back to the point where the black sphere was.

At Higher Levels. When you cast this spell using a spell slot of 8th level or higher, the force damage increases by 1d6 for each slot level above 7th.
