A 10-foot radius sphere of black void tears a hole in reality at a point you can see within range, and massive, squirming, ebony tentacles burst forth from it, wailing wildly in all directions. Each creature within 20 feet of the sphere takes 4d8 cold damage and must succeed in a Strength saving throw or be restrained and knocked prone. A restrained creature can use an action on its turn to make a Strength (Athletics) or Dexterity (Acrobatics) check against your spell save DC, ending the restrained condition on itself on a successful check. A Huge or larger creature automatically succeeds the saving throw.
When a creature enters the affected area for the first time on a turn or starts its turn there, the creature takes 4d8 cold damage and must also make the Strength saving throw.
On each of your turns, you can use an action to pull a creature restrained by this spell up to 10 feet towards the hole. If a creature is pulled into the hole, the target disappears to a plane of the DM’s discretion.
