Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
A simple Jax build for maxing damage and efficiency
the idea of this build is to use the AP and AD bonus on skills and not just maxing ASPD/CRIT
in the fight you should be skirmishing the first lvls, whitout risk too much
if you are in a 5v5 fight you should team up whit someone who can weaken the enemies so you can finish them up
the item's order can be changed to the player's way
the values that appear on this page are different than the ones on the game, this build has more hp and other stuffs
other option is to change the lich bane for a bloodthirster or something with more AD
also is very recommended that you start with Guinsoo's Rageblade than Hextech because of the stacked ability of the weapon, once you have this 2 items you can make a good fight against the other team
other advice is recommended to start with 1 or 2 hp potions and 1 mana potions so you can stand longer in lane.
