This is a guide for the newest champion, Yasuo
The build is based in atk speed, critics, and damage (i will explain later in the guide why i chose those items)
My mother language is not english so excuse me if i make some grammar mistakes, if you have any doubt you can leave a comment or send me a PM
Note: Check the note in the skill section to learn about the "hidden" skills of Yasuo Play Video This is the Champion spotlight, i highly reccomend you to watch it before playing to get a general idea about his playing style and how to use him

I will be adding more chapters like matchups or farming advices

Pros:
- Yasua doesn't use any source for his skills, he doesn't use health or energy or mana
- Way of the Wandereris a life saver
- Last Breath can turn normal cc into hard cc (will explain this later)
- Wind Wall can be used to block strong missiles, like Jinx's Super Mega Death Rocket!
- Steel Tempest reduces its cooldown with Yasuo's atk speed
- Way of the Wanderer allows him to get a high amount of crit chance

Cons:
- Squishy if you dont build heavy health items
- Last Breath needs the target to be airborne, so if you miss your tornado your ultimate will be useless
- If stunned while he tosses an enemy into the air, he will lose the chance to use his ultimate
- Needs to build some items to start dealing some damage

In this section i will explain how each skill works and how to get the most out of it This passive acts in many different ways. It doubles your critical hit chances (it reduces its damage 10%, but with Infinity Edge that's not so bad), Since your Q applies critics it's a good idea to build critic chance on Yasuo. Plus, while you move you will build Flow, which when reaching its maximum amount will transform into a shield when an enemy champion attacks you. In many cases, this can save your life if you get ignited but manage tu run and get the shield on time
The only bad thing is that the shield is triggered by any source of damage, even a basic attack from a mage (deals aprox 80 damage, but will cancel your shield which can be arround 600 in late game) This is your main source of damage and the only way to activate your ultimate. Yasuo strikes towards the place you are aiming (it has no arrow showing were it will go). This skill gets cd when yasuo gets more atk speed, so at 40% attack speed it will reach its minimun cd time which is arround 1,3s.
If you land this skill two times (10 seconds or less after landing the other) the third strike will release a whirlwind which tosses the enemy in the air and allows you to use your ultimate. This skill applies on-hit effects, and you should use it to farm or poke your enemy This skill will create a wind wall a little distance from you, which will stop any proyectile during the time it remains active, including ultimates or even basic ranged attacks.
This item works perfect if you want to stop an adc from dealing damage, or get a turret before it attacking you, as well as blocking many skills during the lane phase This ability has almost 0 cooldown, but it cannot be used in the same enemy during the time it remains marked. This skill can deal up to 100% more damage, increasing 25% each time you hit an enemy minion or champion, so you should farm it up before going for the enemy champion. It is also a good last hit tool and escape tool, or can be used to chase, since its cd is so low and you can keep jumping from one minion to another (like lee sin, but without cd) This skill needs an enemy nearby to be in the air in order to be activated. It's important to know that any skill who tosses enemies into the air will work, so being in the same team of Janna or Malphite is a great idea. When you activate the skill you move towards the airborne enemy, which stays in the air for another second. Afterwards you will damage him and get 50% armor penetration (of the armor they get from items) so you should definitely initiate a teamfight with this skill
If you dont have any champions in your team who can toss enemies into air, you should be careful about missing your Q because you wont be able to use your ultimate in a while if you do

NOTE: Yasuo has some "hidden" skills. If you use E on an enemy and then you inmediately use Q, it will damage enemies arround you (just like katarina does). This works also with the wirlwind, reducing its lenght but applying it to a zone nearby you

I get armor penetration because i dont get it in the items i use (since your ultimate gives you a strong armor pen). Still, you will need a little penetration during the phase lane
My other runes are armor and magic resistance, since in mid lane you can face AD and AP enemies is good to have both of them as runes
My Quintessence is Attack damage to deal a higher amount of damage in early game and also make it easier to farm
