Stormbringer's Boots

This pair of boots has been masterfully crafted using the skin of a nose-horned viper, and then enchanted with Evocation magics that cause them to constantly crackle with electricity. While attuned to this boots, you gain the following benefits:

Crackling Conduit. You have Resistance to Lightning damage.

Lightning Discharge. By taking a Magic Action, you can turn into a flash of light and teleport in a straight line to an unoccupied space within 100 feet that you can see. Each creature in the line is affected by the Lightning Bolt spell.

Once this property is used, it can't be used again until the next dawn, or until you take at least 10 points of Lightning damage in a single instance, as the electrical currents recharge the boots' magic.
