Surgemaster

As a surgemaster of the Order of the Storm, you control the forces of lightning. There is power all around you, just waiting to be harnessed, focused to a purpose. Electricity flows through every inch of your body, making you feel alive. 

Charging Up

Starting at 3rd level, your mastery of electricity begins to supercharge your weapon's strikes. For every attack you make with a weapon made of metal that hits, you gain 1 Charge Point. You can expend any number of Charge Points to gain 1 point of bonus lightning damage per Charge Point expended that you can choose to add to any damage roll. These Charge Points expire at the end of combat.

Power Surge

Beginning at 3rd level, whenever you score a critical hit with a weapon made of metal, you gain 3 Charge Points and you have advantage on your next attack roll.

Conductive Travel

At 7th level, you can cause your body to become pure electrical energy for a time, allowing you to pass through certain conductive materials. As a bonus action, you and any equipment you are carrying can enter and move through purely metal objects at your walking speed. Emerging requires no action. You can remain inside a metal object for a number of rounds equal to your constitution modifier, after which you take 2d8 force damage at the start of each of your turns until you emerge.

Arcing Strike

At 10th level,  When you attack with a weapon made of metal and expend 1 or more charge points, the range for that attack increases by 5 feet.

Also, you gain resistance to lightning damage.

Rising Storm

Starting at 15th level, your skill has made you a whirling maelstrom of danger. Whenever you use your Action Surge, you gain 20 feet of flight on this and your next turn. While flying,  your attacks made with a metal weapon deal an additional 1d8 lightning damage and opportunity attacks deal half damage to you.

Electrified Armor

At 18th level, while wearing armor made of metal, you gain a +1 bonus to AC and half of the damage you take from any melee attack is reflected back onto the attacker. In addition, when you are using Conductive Travel, the object you are travelling through gains this effect and your speed is doubled.
