Chaining

Effect: You create a magical restraint to hold a creature that you can see within range. The target must succeed on a Wisdom saving throw or be bound by the spell; if it succeeds, it is immune to this spell if you cast it again. While affected by this spell, the creature doesn't need to breathe, eat, or drink, and it doesn't age. Divination spells can't locate or perceive the target.

Heavy chains, firmly rooted in the ground, hold the target in place. The target is restrained until the spell ends, and it can't move or be moved by any means until then.

Ending the Spell. During the casting of the spell, in any of its versions, you can specify a condition that will cause the spell to end and release the target. The condition can be as specific or as elaborate as you choose, but the GM must agree that the condition is reasonable and has a likelihood of coming to pass. The conditions can be based on a creature's name, identity, or deity but otherwise must be based on observable actions or qualities and not based on intangibles such as level, class, or hit points.

A dispel magic spell can end the spell only if it is cast as a 5th-level spell, targeting either the prisoner or the Orb of Chaining. The Orb itself is unable to be dispelled, but the current prisoner will be freed.
