Wondrous Item, rare
A set of manacles and chains that attach to a creature's shins, wrists, and neck. The chains extend to an uncomfortable iron and lead helmet which covers the creature's head. They are designed to prevent dangerous imprisoned spellcasters from casting magic or escaping.
The chains restrain the creature, and are imbued with an Antimagic spell. While the creature is retrained by the chains, it cannot cast spells, use telepathy or psionics, or perform other similar effects like magical teleporting. The chains are heavy, and make loud noises when moving. The chains can only be removed with 4 different specific keys, one for each set of restraints.
