This is a good setup if u wanna be the best damage dealer on the track , and also be a little bit tanky .

Here u have some good runes for heal , attack speed , critical damage and damage .

Here u have some attack masteries with a little bit armor and magic resistance .

Here u have some good attack damage items , but if u wanna go a little bit more tanky u can buy a frozne mallet instead of the one bloodthirster .

With this upgrade of skills ur w i will take a lot of damage in the begging .

Often with jax u almost get kills , therfore i took a ignite so u can get every kill instead of letting the enemy escape and have huge luck . I also took flash , because if u are the tank in teamfight , u can easily escape with flash .

Here i think u have the best build to get some good damage with jax , but u also can be a little bit tanky .

If u wanna get a good farm , u could last hit the minions with your w .
