The calm before the Storm. Following this ancient wisdom you have trained your body and mind to harness the power of Wind and Storm. 

Windfury

At 3rd level you gain the power of the wind. Windfury grants you a chance to create echos of your successfull unarmed attacks. 

If you roll a 18 or higher on the d20 you roll to hit, you trigger Windfury. 

Windfury creates an echo of your attack, dealing the same damage as the attack triggering it as lightning damage. 

Lightning Shield

You gain the ability to cast Lightning shield on yourself. 

Use your Bonus Action to spend 1 Ki-Point to cast lightning shield on yourself. 

You gain 10 temporary Hitpoints, and 3 charges of Lightning Shield. Getting attacked or touched uses one charge to deal 1d6 lightning damage in return. 

You can spend up to 5 Ki.Points on this, every 2 additional Ki Points grant you 10 additional temporary Hitpoints, 3 additional Charges and an additional 1d6 lightning damage.

Throw Lightning

At level 11 your mastery over the storm grants you the ability to cast Chain Lightning. 

You can cast it on a target you can see within 150 ft. Additional bolts of Lightning strike to targets within 30 ft of the first one. Targets hit have to succeed on a DEX save or take 10d8 lightning damage. Deals halve as much damage on a successfull save. 

You have to spend 1 Ki-Point for every target hit up to a maximum of 5. 

Conduct Lightning

Electricity flows through your body, empowering your unarmed attacks.

The range of your unarmed attacks increases by additional 5 ft and dealing extra lightning damage equal to your WIS-Modifier.

Windfury doesn't echo this damage, instead a target has to succeed on a CON save against your spell save DC or lose it's reaction until the end of it's nex turn.
