Void Grenade

Wondrous item, very rare

This glass orb is seemingly filled with a tiny cosmos. When you take the Attack action, you can replace one of your attacks with throwing the orb at a target you can see within 30 feet of you; the target can be a creature, an object, or a point on a solid surface. The orb shatters on impact, destroying it and unleashing an instantaneous pocket of the Astral Plane. Any creature or loose object within 15 feet of the point of impact must make a DC 16 Strength saving throw. On a failed save, a target takes 10d10 force damage, is pulled to the unoccupied space that's closest to the point of impact, and is knocked prone. On a successful save, a target takes half as much damage and isn't pulled or knocked prone. A target that fails the save is briefly lifted into the air before being pulled in this way.

Creatures within 5 feet of the point of impact make the saving throw with disadvantage. A creature that rolls a 1 on the saving throw is pulled into the instantaneous void created by the orb and transported to a random location on the Astral Plane.

The cold silence, worsened yet by the unyielding pull of forces beyond our ken. There are many reasons to be grateful to be firmly on the Material Plane.
