Champion Overview:
Jax is a Mobile sustained burst assassin. Jax excels at farming into late game and can carry his team like a Riven or an Irelia. Jax is the only champion in the game that is capable of "Dodge". Meaning basic attacks will not be able to hit him when his E is on. Jax deals hybrid damage and is thus very hard to itemize against. Jax can also build to counter his opponents with his ultimate, meaning if the enemy team has a lot of magic damage he should build Ap, and if they have alot of physical damage he should build AD.

Skills Overview:

Passive: Relentless Assault- Jax's consecutive basic attacks continuously increase his Attack Speed. (4-10% attk speed per stack depending on his level.)

Ok passive, is ok for getting last hits and it gets to be a decently sizable amount late game.

Q: Leap Strike- Jax leaps towards a target. If it's an enemy, he attacks it and deals an additional 70/110/150/190/230 (+100% of Bonus attack damage) (+70% of ability power) magic damage. Cooldown 10/9/8/7/6 seconds. Cost 65 mana. Range 700.

Your Gap closer AND escape move as you can use on enemies or allies.
Note: You can hop to a ward with this move.

W: Empower- Jax charges his weapon with energy, causing his next attack to deal 40/85/130/175/220 (+60% ap) bonus magic damage. Cooldown 7/6/5/4/3 seconds. Cost 30 mana.

A very nice damaging move, its on a low CD and it resets the auto attk timer.

E: Counter Strike- Jax enters a defensive stance, dodging all incoming basic attacks for 2.0 seconds, and reducing the damage of AoE attacks by 25%. At the end of the effect, Jax deals 50/75/100/125/150 (+0.5 bonus attack damage) physical damage and stuns nearby enemies for 1 second. This spell deals an additional 20% damage (up to 100%) for each attack dodged. This attack can now be ended early to deal the instant stun. Cooldown 18/16/14/12/10. Cost 100 mana. Range 400

The Original Esports titl.... Oh wait Jax's counter strike. This move gives you auto attack immunity for a set period of time AND after a few seconds or when you cancel it, this skill will stun nearby enemies.
Note: Your E dodges all moves that would apply on hit effects while spinning such as Fiora or Warwicks ultimates.

R: Grandmaster-At-Arms- Passive: Every third consecutive attack deals an additional 100/160/220 (+0.7 ability power) magic damage.
Active: Jax Strengthens his Resolve, Gaining 25/35/45 Armor (+30% of your AD) and 25/35/45 Magic Resist(+20% of your Ability Power) For 8 seconds. Cooldown 80 seconds. Cost 80 mana. Range 100

The passive of this skill makes your auto attacks deal a good amount of damage, this will be a good part of your damage output do not underestimate this passive. The active component of this skill makes you very durable while it is on, so remember to use it when you go into a fight.
Passive Note: When your passive attack speed stacks wear off, your consecutive attack count resets.

Combos/Skillorder:

Skillorder:

Max R>W>Q>E

Combos:

E-Q-Auto-(Keep E on if they try and fight, E instantly if they try and run)-W-(R if a full fight starts)

Matchups:

Easy:

Tryndamere (all autos, hes gonna miss them all and die), Fiora (Same as tryndamere AND you dodge her ultimate and stun her after lol), Irelia (The majority of her damage is autos and you out trade her), Renekton (Dodge his stun damage component, which is a big portion of his damage), Riven (She needs to auto to deal a good portion of her damage), Gangplank(Dodge his pistol hop to trade back stun and DPS- Profit.), Master Yi (See tryndamere and Fiora), Jarvan IV dodge his auto harass and once you get your skills you will be able to out trade him.

Hard:

Lee Sin (Sustain all Day HUEHUEHUE), Yorick (Your Death Will only be the beginning), Warwick (Yea, Try hurting him its not fun.), Mordekaiser (Numero Uno, beg for ganks), Teemo (He will blind you making you miss your autos, and he will lay a mushroom for if you want to fight him).


Playing As/Vs:

As:
-Count your ultimate passive. When its at 2 you can be aggressive with your Hop-Auto-E Which will deal ALOT of quick burst damage.
-Time your dodge use so it will be up when their skills are down and they want to auto you.'
- Remember to use W as an Auto attack reset.
-Having a ward at all times in essence gives you another flash resource.

Vs:
-Avoid fighting Jax until his dodge time is over
-Do not underestimate a Jax's burst damage he can wreck you very fast.
-DO NOT DIVE A JAX IF HIS STUN IS UP, HE WILL DODGE YOUR ATTACKS AND STUN YOU UNDER TOWER.

Big Item Choices:

Trinity Force- All the stats help you, and this item makes you a carry monster

Hextech Gunblade- Sustain, Damage (In both types to benefit your ultimate), and a slow damaging active effect.

Wit's End- Strong item for dmg(Magic which they probably wont itemize against, this plus your true damage means a good bit of your damage is almost unaffected by resistance), Atkspeed, and Mr.

Ionic Spark- Good for split pushing.

Maw of Malmortius- Gives you durability against mages and warriors at the same time.

Guinsoo's Rageblade- Good gold value item, use it if the enemy team has an up close fighting comp that will allow you to auto.

Gametypes:

SoloQ:
Who wants a piece of the champ? In soloQ you can use Jax's snowbally nature very well, he snowballs and can effect games in the exact same way as a riven. He has very good matchups and on top of that can transition very well into late game, making him a VERY strong pick to carry people in SoloQ.

Ranked 5s:
Hes been in the tournament scene alot recently, His ability to get one good gank and be a very beneficial carry for his game is amazing. He also has the ability to recover from a bad laning phase if your team helps you by letting you farm, trading, or ganking form you when your down.

Conclusion:
Jax is currently a very strong champion in all regards. He is someone worth learning that can be a very powerful pick for your team or your just general gaming. He has a decent skillcap in the timing on his skills but once you get that down you should be fine, as always have a good day and good luck on the fields of justice summoners! =)

SERIES UPDATE:
I plan on releasing these every day/other day until I get all of the top lane picks in the league ( about 50-60 of them) if there are any requests leave in the comments below and ill work on them. I want to make this series for others to better understand the champions of top lane. Once I am done (Or once I have a few top facts out) I will release some Facts about top lane mechanics, eventually I will probably put everything into one generic top lane guide, however until I do that I will continue to watch and update my blogs as needed. Tips and tricks I missed under my Top Facts would be helpful if you put anything I don't have in the comments I will be sure to add it. I will be forming a guide called The complete guide to Top lane or something in that nature. The intention of this series is not as a "Build guide" or a "play guide", these are more like facts you should know about the champion. These are to inspire people to think of new champion possibilities they might not have thought of or to help a new player with the champion. I do not list runes masteries or a set build ( I give a kind of recommended items) in here due to the fact I want people to think of that for themselves and try new things. This series is an attempt for the LOL community to try new things and have fun in a fun game. Thank you for reading and have a nice day:P
