You summon a melon-sized orb of pitch-black gravity in an unoccupied space you can see within range that lasts for the duration. The area within 100 feet of the orb is difficult terrain, and the area within 30 feet of the orb is difficult terrain that costs 3 feet of speed for every 1 foot of movement. The area spreads around corners. At the start of each of your turns, each creature within 100 feet of the orb must succeed on a Strength saving throw or else take 3d10 bludgeoning damage and be pulled 20 feet toward the orb. Creatures within 40 feet of the orb make the saving throw with disadvantage.

The orb can pull creatures off the ground and into the air unless they can grab onto something which is firmly rooted to the ground. When a creature that cannot fly is pulled into the air by this spell, it remains suspended there until it can make it back to the ground, escape the area of the spell, or the spell ends, at which point the creature falls if it can't fly. A suspended creature has disadvantage on Dexterity saving throws and weapon attacks, attacks against it have advantage, and it can move only by pushing or pulling against a fixed object or surface within reach (such as a wall or a ceiling), which allows it to move as if it were climbing.

A creature that enters the orb's space or ends its turn there takes 30d6 bludgeoning damage. This damage ignores resistance, and any creature or object that is reduced to 0 hit points by this damage is obliterated entirely, leaving no physical traces remaining. While it remains in the orb's space, it suffers the effects of being suspended in the air, and its speed is reduced to 0 feet.

When you cast this spell, you may designate up to 6 other creatures that you can see within range as being protected from it. They automatically succeed on saving throws against the spell. You are totally immune to the spell's effects, except that you still take damage if you enter the orb's space or start your turn there.

The spell also affects and damages objects in the area that aren't being worn or carried.
