This rusty iron sphere measures 3 inches in diameter and weighs 1 pound. You can take a Magic action to throw the sphere at a Huge or smaller creature you can see within 60 feet of yourself. As the sphere moves through the air, it opens into a tangle of metal bands.
Make a ranged attack roll with an attack bonus equal to your Dexterity modifier plus your Proficiency Bonus. On a hit, the target has the Restrained condition until you take a Bonus Action to issue a command that releases it. Doing so or missing with the attack causes the bands to contract and become a sphere once more.

A creature that can touch the bands, including the one Restrained, can take an action to make a DC 20 Strength (Athletics) check to break the iron bands. On a successful check, the item is destroyed, and the Restrained creature is freed. On a failed check, any further attempts made by that creature automatically fail until 24 hours have elapsed.
Once the bands are used, they can’t be used again until the next dawn.
