Wondrous Item, uncommon
These shackles were designed by arcanists of the Azure Court to prevent the casting of magic by arrested and imprisoned people. While these shackles are affixed to a creature, the creature is under the effects of an Antimagic Field. Additionally, any attunements the creature has are considered to be unattuned while bound by these shackles.
However, these shackles do not prevent magic from affecting the captured target. For example, someone not bound by these cuffs could telepathically communicate with someone who is.
