Manacles of Stasis

The Manacles of Stasis shackles that allow a spellcaster to expend a spell slot to cast a variant of Sleep on the wearer. Multiple sets were used by the Iron Shepherds to keep Fjord, Jester Lavorre, Yasha Nydoorin, and other abductees in captivity. After their rescue, the Mighty Nein kept at least one set, which Caleb Widogast used against Essek Thelyss and Trent Ikithon.

Description
The Manacles of Stasis are a pair of metal wrist shackles intended to restrain behind the back connected by a chain to a pair of ankle shackles. Altogether, they weigh fifteen to twenty pounds. They have a lock that can be picked.

They allow any spellcaster to expend one of their spell slots to cast a variant of Sleep on the wearer. As with the version of the Sleep spell described in the Player's Handbook, the caster rolls 5d8 with an additional 2d8 for each level of spell slot above 1st-level, and if it totals above the target's current hit points, the target falls asleep; unlike as described in the Player's Handbook, the spell targets only the wearer of the manacles and, if successful, renders them unconscious for 24 hours. The spell may be cast from an unspecified but short distance away and does not require touching the manacles. It is unclear if a sleeping creature may be roused.

History

 * : Creatures in the Victory Pit wore manacles their handlers used to put them to sleep.
 * : Fjord, Jester Lavorre, and Yasha Nydoorin were kidnapped by the Iron Shepherds and restrained by these manacles, though without being put under its Sleep spell.
 * : The Nein rescued the three and release them from the manacles, though Yasha was still under the effects of its Sleep. Jester explained all abductees wore the manacles, which Ruzza used to put them to sleep, and Fjord discovered Lorenzo carried four sets inside his Bag of Holding. After casting Identify and describing the manacles' properties, Caleb Widogast offered it to Jester and, when she expressed pointed disinterest, kept it himself.
 * : While preparing for an interception at the Overcrow Apothecary, the manacles were first named as the Manacles of Stasis.
 * : The manacles were briefly placed on Halas' body, though without casting Sleep, to preemptively prevent him from spellcasting should his soul return to it. Jester described the manacles as having prevented Fjord and herself from casting. However, the manacles do not display specific anti-magic properties, so either Laura was mistaken, was referring to binding a caster's hands to render them unable to perform somatic components, or was referring to the Sleep effect.
 * : When the Nein corner Essek Thelyss to confront him for the theft of the Luxon beacons, Caleb used the manacles to cast Sleep at 6th-level. The spell failed to put Essek to sleep, and he escaped the restraints using Misty Step.
 * : After Trent Ikithon was subdued at the Blooming Grove, Caleb used the manacles to cast Sleep at 5th-level to successfully put Trent to sleep. They were used repeatedly on Trent for the days the Nein kept him captive before turning him over to the Cobalt Soul.
