So hello there!

First of all, i would like to apologize to all of you, beacuse of my english. I will try my best to be clear and understandable, but you understand english is not my native language.

So after we've discussed my perfect english, let's see the guide.

If you look at my runes and my list of item purchase, you'll see that this guide's disadvantage is the early game, beacuse basicly your runes just simply be worthy above lvl 6 or 7, and for early game, you dont really own any kind of doran's item.

AND THIS IS THE POINT OF MY GUIDE. WE ARE BULDING A LATE GAME JAX. WHY? BEACUSE JAX'S ITEMS ARE SO EXPENSIVE, WE CANT AFFORD USELESS ITEMS IN LATE GAME SUCH AS DORAN'S RING/SHIELD/BLADE.

Pros:
- if there is a rightclicker in the enemy team, like rammus, you are gonna eat it :)
- your Q spell is a great assassin spell, also a great escape spell, beacuse you can jump to a friendly target :)
- if there is minion wave focusing you, while you are fightin with somebody, the win is nearly always garantueed beacuse of the stun :)
- Jax ultimate gives you durability and great power if you can hit targets countinuesly

Cons:
- beacuse we are building a late game jax, you are gonna s*ck in early game, sometimes in midgame too ( usually when you get gunblade it is going to be much easier :))
- if the enemy team is more like a caster AP team, and there is no carry (rightclicker) you are probably gonna have hard times
- These items are really, really expensive :(

So i think the structure of my runes is simple.

DOGDE ftw. beacuse if you can doge, you can stun. if you can stun, you can CC. if you can CC, you are a good member of the team:)

ability/lvl. this is a late game build, this is why these are not instant runes. More ability power means more BURST DAMAGE and more HP.

attackdmg/lvl. as i mentioned, late game. But if you prefer to magic penetration, you can also have it. I think ad is more useful beacuse it increases our health, also it is a hybrid build :).

The thing about Jax, in late game as far as i experienced it, s*cks in lane. It is possible to jungle with him, but i do not really suggest it. As a jungler, it means, that you would poissibly max your E first. Which is a good thing when you are fighting against minions and monsters, but definitely not against players. Give it a point in the beginning and max it by lvl 18.

But there is a good thing being in a lane. About lvl 8-9 you will probably have some items, and you can engage enemies while their minions live. Attacking an enemy champion means their minions are going to attack you, which eventually will give you dodge. DODGE.What did i say in runes chap? DOGE MEANS STUN. STUN MEANS CC. CC MEANS WIN.

Masteries are petty simple too. Exhaust against heavy targets, or 1v2 or even 1v3 in LATE or LATEMID GAME. Cause you can rape them. Cause you are a híbrid JAX. Also your target's magic resistance and armor will be reduced. Its simply that good.

Archatic knowledge is for biggest burst obviously. Defensive tree is beacuse of the dogde and attack speed and ability power buff.

DO NOT START WITH DORAN'S ITEM. It will be harder in the beginning, but you are a tough guy, you can handle it.

ninja tabi - you can guess why.

rageblade - this and you ultimate passive is just ridiculous. You can destroy turrets in no time

sheen - the reason beacuse you purchase it before trinity is that it is just easier to rape somebody.

gunblade - must have híbrid item. Also instead of crystal scepter, you can purchase another one. The stats are just ridiculous.

trinity - excpet for the crit, everything is needed for jax.

scepter - lol, it gives hp, ability which give MORE HP, and SLOOOOOOW.

lich - imagine the bonus damage from your lich and trinity after you pressed Q and W. INSTANT KILL.

Basicly, when you use this guide, you must be awere of the other enemy early game champs. Again, as i mentioned a lot of time, from my point of view, this guide only weakness is the early game. But that's it. After 10-15 minutes you are fine. Really. You will be a great harasser, also a great ganker. Farming will be a lot easier, beacuse of the effects of you ulti and your rageblade :).

So playstyle:
You always want to focus the squishy ones and the carrys. Literally, in the beginning of the battle, you always want to focus these hostiles. After you are done with them, you probably have some attack speed/ability power stack on you, so can turn to tougher targets like offtanks. On the other hand, i don't really suggest focusing tanks, beacuse in this guide you have literally no armor penetration. So you are not a tank eater. Keep that in mind.
