An elaborate and ornate cage of white light appears around you, blackness filling indistinct holes in the cage, before the entire cage collapses into a small, rapidly swirling sphere of light and black energy. You then release the energy, which attempts to absorb any number of creatures or objects you choose in a 40-foot cone originating from you. Each unwilling creature must succeed on a Strength saving throw or be pulled into the sphere. Each creature and object in the sphere is considered to be incapacitated on a harmless demiplane inaccessible and inescapable short of a wish. The sphere then becomes a weightless adamantine metal sphere three inches in diameter. The sphere has immunity to poison and psychic damage, 1 hit point, and AC equal to your spell save DC.

When you activate the sphere as an action, when the sphere is successfully targeted by a dispel magic spell, or when the sphere drops to zero hit points, all creatures and objects trapped in the sphere are released in a 40-foot cone originating from the sphere, in the same arrangement as when the sphere absorbed them. A creature or object that exits the sphere in an occupied space takes 4d10 force damage and reappears in the nearest unoccupied space.

Casting this spell while a sphere created by this spell cast by you exists causes that sphere to be destroyed.
