Rod of Planar Travel

Rod, very rare (requires attunement)

This ornate rod has a crystal button halfway along its length. You can use an action to push the button and then make a DC 15 Intelligence check. On a successful check, the rod opens a gate (as per the gate spell) to another plane of your choice. On a failure, you and each creature and object within 15 feet of you are pulled into a random plane.
