Hello,
This build is going to be something kind a hard damage hard to kill and pretty offensive Jax. The main thing is the confuse in the enemy about your build. You are goind to kill evreything and to can tank turrets.

In the laning phase you need to farm, The main thing is if you farm more you will get the items faster. Try to not use your mana a lot, couse Jax is pretty OOM champ. Kill on EQW combo you need 2 or 3 combos just haras the enemy with your auto atack. If you want to do more damage with E you need to hit an auto atack on the enemy and then the minions will start hitting you, then you will get more damage.

In the mid game you need to fight and to go back and spilit push in lane. You need to start feedling when is the best moment to split push, couse you can do a big mistake and your team to lose a lot. This is the hardest phase. You need to controll almost evrey lane.

Here you are just a beast, you dont need a lot. When you have 4/5 full items you are a beast. Just start killing and getting some objectives (Dragon, Ace, Inhibs, Ase, Baron, END)
