Not Updated For Current Season
After alot of trys with alot of build and masteries with jax , i came with this OP build
This build is one of the best [ LEEERRROOOYYY ] builds for jax , empower and leap , and if you are in the middle of the fight , all you would do , is spam click W and E , easy kills , great tower nuker , you can replace rylai's Crystal Scepter with frozen mallet .
Ofc we start with guinsoo's rageblade to acompany the Ulti , and Phanton dancer afterwards for the dodge to add up on the boots , so when you leap on a target , better to be some enemy minions around to hit you , and give you free dodge , if he wanted to run even , at this point you may hate Jax , he kills fast and he dies faster , you need the Spell Vamp+ Life Steal combo , now you have the damage - the speed - the avoidance - the movement speed , you are missing the last piece , that give you slow+AD+AP+next attack , and ofc [AD&AP = HP] , and at last Rylai's or Frozen mallet , for the slow and the HP , HP from the aD or AP as I said .
If you have any questions or anything to add , and I'd be more than happy to welcome any opinions for a more OP build .
Best wishes NnLOL
