Arc Jumpers

While wearing these boots, you can use a bonus action to spend a charge to teleport to a location that you can see up to 60 feet away. Upon teleporting, any creature within 5 feet of where you teleported to and from must make a Dexterity saving throw (DC 15) or take 2d8 lightning damage on a failed save, or half as much on a success. 

These boots have 5 charges. They regain 1d4+1 charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the boots lose this property and become non-magical boots.
