Storm's Disciple

At 3rd level, you know the lightning lure and thunderclap cantrips.

Constitution is your spellcasting ability for these spells and you can cast them even while raging.

Storm's Fury

Beginning at 3rd level, the fury of the storm accompanies your attacks. Your bonus rage damage is considered thunder damage.

In addition, once per turn while raging, you may deal an additional 1d6 lightning damage on a successful weapon attack.

Tempest Shield

At 6th level, the power of the storm protects you from its elements. You gain resistance to lightning damage and thunder damage.

Ride the Lightning

At 10th level, you can harness the storms energies to travel short distances as fast as lightning strikes.

You can cast the thunder step spell as a 3rd-level spell without expending a spell slot.

Once you use this feature, you can't use it again until you finish a short or long rest.

Constitution is your spellcasting ability for this spell and you can cast it even while raging.

Lightning Strike

At 14th level, you can call down the might of the storm onto your enemies.

In addition, when you hit a target with a weapon attack, you can use your bonus action to call down a lighting strike on it.

Choose one of the spaces occupied by your target. The target and each creature other than you within 5 feet of that space must make a Dexterity saving throw (DC equal to 8 + your proficiency bonus + your Constitution modifier).

A creature takes 2d10 lightning damage and 2d10 thunder damage on a failed save, or half as much damage on a successful one.

You can use this ability a number of times equal to your Constitution modifier (minimum 1). You regain all expended uses after you finish a long rest.
