Stormheart

Be still. The wind screams more than howls. Rain falls as stones. The trees bend and moan in wrath enough to scare the Gods, branches torn like paper limbs. This storm more wicked than any in living memory, is watched through debris that tumbles, heavy like bullets, destroying anything and everything, avenging the forgotten.

Stormheart's are rogues trained in the highest of secrecy. Elite warriors of the tribes they serve, they bend lightning and use it relentlessly to pursue opponents. Hard to pin down they present as formidable foes in the tides of war.

Lightning Conduit

At level 3, you are swift as the lightning, your walking speed increases by 5 feet, and another additional 5 feet at level 8 and level 16.

In addition, when you use your Sneak Attack, you can choose to turn your Sneak Attack damage into lightning damage. If you do so the target cannot use reasons until the start of your next turn. You can use this feature a number of times equal too 1+constitution modifier per long rest.

Storms Reprisal

Starting at 3rd level you learned to create bolts of lightning from your body. Immediately after you use your Cunning Action, you can make a ranged spell attack against a creature within 30 feet of you, provided you used the Attack Action and haven't used your Sneak Attack this turn. You are proficient with it, and you add your Dexterity to its attack roll and damage rolls.

A creature hit by this attack takes lightning damage equal to half your Sneak Attack damage (roll divide by 2). This uses your Sneak Attack for the turn. This ability can be used with the Lightning Conduit feature

Prophetic Tempest

At 9th level, you can commune with the destructive element that is the Storm, learning about the path ahead. When you do so, you cast the divination spell, without using a spell slot or material components. Constitution is your spell casting ability for this spell.

Communing in this way invigorates you. When the spell ends you gain temporary Hit Points equal to double your Constitution modifier.

After you cast the spell with this feature, you can't do so again until you complete a short or long rest.

Cloudburst

At 13th level, right after damaging a creature with your Sneak Attack feature, you can teleport up to 30 feet.

In addition when you kill a creature of CR 1 or higher, you regain 1 use of Lightning Conduit feature.

Stormborn

Lightning envelops your body. At 17th level, you have a flying speed equal to your current walking speed whenever you are not underground or indoors
