Jax is the best champion for me,u can kill everybody very easy.He is the char i play most cause he is just a killing machine.

I used to use offensive masteries but it is not worth when in team battle.So i chose 9/21/0 in order to increase jax's defense but still i cant neglect the offensive site of jax.Thats why i put 9 points in the most important offensive masteries.

First we have Lesser Mark of Desolation which gives jax armor penetration.It is very important cause it makes u able to kill enemies mostly in the early stages.Ok its obvious tha i chose Seal of Evasion cause it provides jax dodge chance.In addition Greater Glyph of Potency to provide jax some ability power from the beginning.Trust me,it will be very usefull.

1)For the beggining i take cloth armor an 1 or 2 red potions.After that i take ninja tabi in order to have some good armor and increase jax's dodge chance.

2)Pickaxe,it will give jax attack damage and some health(cause of jax's passive).Pickaxe will open your way to Billgewater Cutlass and after that to Hextech Gunblade.

3)Last whisper!!!:is jax's bread and butter.It gives attack damage(+some life,jax's passive) and the most important armor penetration.After u take this item u will be able to kill everybody in 1vs1 battles

4)Zeal,it gives some movement speed which is really usefull.In addition it provides critical damage and attack speed(+20%)

5)Abyssal scepter gives nice A.P in order to kill enemies quite more easy.It provides 57 magic resistance which is also significant.

6)Now comes rylai scepter,which will give u another 80 AP and 500 health.

7)Your zeal has opened the way to take an Phantom dancer,THE LAST item to finish his build.+55% attack speed will make it easy to slain everybody very fast.It also gives critical damage and 15% movement speed(very important)

1)Exhaust:the most important,it will make imposible to be killed in one vs one battles and could be usefull to catch enemies before they escape.

2)Flash will make it able to go fast somewhere when there is need.
