Tether

You touch two Tiny or Small non-magical objects that aren’t being worn or carried, and create a visible yet ethereal tether between these two objects. For the spell’s duration, the two objects cannot be moved more than 5 feet away from each other. The tether is dispelled if the objects are ever brought further than 5 feet away from one another. A creature can attempt to sever the tether by making a Strength (Athletics) check against your spell save DC, severing it on a success.
