i choose this iteams beacause jax should have life steal vamp steal and have as equal as much posible ability power and atack damage beace of his pasive (at 18 lvl u will have 3k health) and as for the rest iteams is about atack speed movment speed coldown reducion if u take this iteams u will be able to kill 3 guys vs u realy easly . the spels are chosen for 3v3 but for 5v5 i recomend to take heal
as about the runes i recomend those ones because you will have and advantage on erly game you will have around 100-200 health more than all players and more damage and dodge so it wont be difoult for you to take first blood . as you reach 10-12 lvl and you have sheen and vampiric scepter u will be able to take all mini bosses prety easly and equal easy the dragon( 3v3)
to be honest i just wanted to show my opinion about my build with jax and i think he isnt soo hard to play after u play 4-5 game you will easily learn him well


i am not sure if i can make a post of 5k word but i made my best to let u know why to get jax and why to select those iteams i hope u like my build and u will follow it on game:) i belive that 5.000 word's are too much but i did my best to let you know about this special characher
