This is my first guide,im not good at english so dont mind me at mistakes ;).I decided to write this guide becasue i've seen a lot of different builds on Jax,and i wanted to put mine build and style of playing.

For masteries,i take dodge and nimbleness in defense,exhaust and dmg in offense.There is nothing to talk about masteries,if you want to see how i set masteries,there is setup in guide.

Well,runes for Jax..There are a lot of different types of runes for jax,it depends how you play him.I go:
Marks-Pure dmg,because of little hp boost on beginning and added dmg to leap strike.
Seals-Dodge,its a little boost,noticable in late game if AD carrys focus you,or in early game if you go in wawe of minions.
Glyphs-Pure AP,it will increase your burst in early game,and boost HP aswell.
Quints-Dodge,same as seals.

I start with doran's blade,to boost my hp.When i first go back i buy ninja tabi and vampiric scepter.2nd back i buy bilgewater cutlass.Than i farm for my hextech gunblade.If i finish this item on time,i can go in 1v1 battles with someone who farm on lane without tower.This is my core build.I buy hextech gunblade becasue after that item you are unbeatable 1v1 cuz of lifesteal,spell vamp and hp from ad and ap from that item.
Other items:-Atmas impaler-armor,crit chance and 2% hp to dmg.That sounds beautifull becasue of your passive.
-Frozen mallet-hp,dmg,slow with normal attacks.Jax isnt so fast until he dodges normal attack,but more hp and dmg sounds great,btw another reason i buy frozen is that slow.Example:jax isnt so fast,he can jump onto someone and normal attack it and slow it,and if he passes throught minions wawe he will dodge some of minion attacks and become faster and automatic become chasing machine.
-Infinity edge-dmg,crit chance and more crit dmg.It compares great with atmas impaler and later trinity force.When you turn on W ability it will turn on trinity passive and if you crit you will deal ton of dmg with one hit.
-Trinity force-all that jax needs.Great passive,great stats.That explains alot :D

I will post video later,but now i will explain gameplay in short.
Early game-Duo lane-harras them with Q+W then run back.If there is opportunity,go to fight,but jax dont shines in early game battles on duo lane.
-Solo lane-FARM,FARM,FARM,FARM!Dont answer on harrasment just kill those fcking minions.When you get farmed,harrasers will regret.You will jump on them,4 shot them and they will QQ.Key to be good jax is easy farm and get Hextech as faster you can.Than you can gank and beat the **** uot of them.
Mid game-If there is battle,NEVER INITIATE WITH JAX UNLESS YOU ARE FED LIKE A PIG!Wait tank to initiate and than go up and kick squishys ***es,than focus on badasses like nasus,trynd or others.
Late game-They will probbably surrender by then cuz you are pro xD,but in late games jax shines.With full build 1v3 is easy one,1v4-at least tougher but you will probably win,1v5-if you are god and they just run from you.In other cases don't.Just don't.

Well if you are happy with my guide,comment and rate it.If you are unhappy,dont qq in comments and write bad things.I will upload few videos later.By then enjoy ;)

P.S:GUIDE WILL BE UPDATED.DONT QQ ABOUT HIS SHORTNESS.
