Your regular set of dimensional shackles let you down? Acquisitions Inc. introduces these anti-transmutation dimensional shackles.

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 extradimensional movement, including teleportation or travel to a different plane of existence. They don't prevent the creature from passing through an interdimensional portal. The shackles also prevent the creature from shapechanging, polymorphing, or altering its form in any way. Even a creature's Shapechanger racial trait is shut down. These shackles are that good.

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.
