You can use an action to place these shackles on an incapacitated creature. The shackles adjust to fit a creature of Small to Large size. In addition to serving as mundane manacles, the shackles prevent a creature bound by them from using any method of arcane magic. They don't prevent the creature from passing through an inter-dimensional portal or being affected by outside arcane forces.
You and any creature you designate when you use the shackles can use an action to remove them. Once every 30 days, the bound creature can make a DC 30 Strength (Athletics) check. On a success, the creature breaks free and destroys the shackles. Once every 30 days, any creature can make a DC 32 Strength (Athletics) Check to break the shackles.
Notes: Restrained, Control, Utility
