A skilled warrior who is able to use the wind to increase his fighting abilitys in the field. His proficiency with air slashing and fast movements mave him allow to fight enemys in close combat., you can use the wind as your weapon, infuse his power on your attacks and manipulate it to your own profit.

Recomended stats: Strenght or Dexterity and Wisdom.

Its a melee subclass, you dont need any specific weapon to use your mechanics 

This Subclass is highly inspired in Yasuo the League of Legends champion as you can see. The point i tried to make in thi subclass is an agressive fighter with some new fighting mechanics.

This Class is based in your tornado skill, Steel tempest, a skill that scales with you level, another mechanic that you will explode is the Prone statatus what is missapreciated in 5e in my opinion.

When you reach high levels in this subclass the amount of damage you can make its really dangerous even for a big boss.

I hope people enjoy this Subclass and try it, i know my english is not perfect and i hope you dont care about it.

I would like to read your comments and suggestions!!

Steel Tempest

At level 3 you are able to infuse wind in your weapon, In your next attack action you use one of your wind infusion  to transform the melee attack into a 20 feet range attack without melee disadventage  launching a 5 feet tornado in a 20 feet straight lane making 1d8 of Slashing damage. The first creature hit by this attack receive the weapon damage and the tornado damage, the others only receive the 1d8 damage.
