Stormborn

You have learned to tap into The Storm itself, gaining the ability to strike down foes with all the force and fury of a tempest.

Lightning Edge

As a bonus action you can sheath your weapons in lightning. Each attack deals an additional 1d4 lightning damage. This effect lasts until you finish a short or long rest, or if you aren’t holding the weapon at the end of your turn.

At level 10 Lightning Edge is improved and each attack deals an additional 2d4 lightning damage.

Harness Lightning

You gain the ability to harness the storm within yourself and direct it outward as lightning bolt.

As an action, a stroke of lightning forming a line 100 feet long and 5 feet wide blasts out from you in a direction you choose. Each creature in the line must make a Dexterity saving throw. A creature takes 8d6 lightning damage on a failed save, or half as much damage on a successful one.
The lightning ignites flammable objects in the area that aren't being worn or carried.

This ability can only be used one time per short rest.

Jump Start

At level 10 you can add your proficiency bonus to your initiative roll, and you gain advantage on attack rolls against any creature that hasn’t taken a turn in the combat yet.

Electrocute

On a critical hit you can discharge the electricity coursing through your body into your opponent Stunning them until the end of your next turn.

Eye of the Storm

As an action you can create and command a storm. 

A storm cloud appears in the shape of a cylinder that is 10 feet tall with a 60-foot radius, centered on a point you can see within range directly above you. The spell fails if you can't see a point in the air where the storm cloud could appear.

When you cast the spell, choose a point you can see under the cloud. A bolt of lightning flashes down from the cloud to that point. Each creature within 5 feet of that point must make a Dexterity saving throw. A creature takes 5d10 lightning damage on a failed save, or half as much damage on a successful one. On each of your turns until the spell ends, you can use your action to call down lightning in this way again, targeting the same point or a different one.
If you are outdoors in stormy conditions when you cast this spell, the spell gives you control over the existing storm instead of creating a new one. Under such conditions, the spell's damage increases by 1d10.

You can only use this feature once per long rest.
