Hello! This is a Jax build for 3v3 . Please try it before u rate /comment. Thx.

For masteries i chose 9/21/0 cuz the defense mastery can help u to take the first blood and survive untill u reach level 6.

For items i use a mix between ability power and atack speed because Atack speed makes your ultimate faster to reach and ability power for more damage.if another jax is on the enemy team u MUST buy Sword of Divine for it's active cuz it makes your atacks UNDOGEABLE ( that means , the enemy jax cant dodge your atacks and he cant use conter strike).Sell Doran's shield when u need 1 more item slot to complete ypur build.

Jax it's the ,,Right click to win" champion so u just need to use empower( W ) and Counter Strike ( E ) when are ready .

In 3v3 matches u should ALWAYS get the solo lane just because you are a CARRY champion and when u reach level 6 u CAN 1v1 every champion in LoL.
Try to make your minions to atack you for a few seconds, dodge an atack then Empower+leap then conter strike.After that get back.

For summoner's spells i use Ignite and Exaust .
Alternative Spells :
-Ghost : if u are a ganker in a premade match u can use Ghost for a Rapid Lane-change and gank your enemys.
-Flash : U can use flash to : catch an escaping enemy ( Flash + Leap) or escaping . But best use of flash is ,, Flash over wall trick.U can flash over dragon's wall ,nexus wall , lizard wall, etc.
Do NOT use:
-clarity : Jax is NOT a mana eater
-clayvorance: maybe let a support to take it .
-rally: fail spell for everyone
- fortify: for tanks
-Smite : u are a very good jungler and u dont need smite.

1-5 levels: U can use Empower for last litting minions but be carefull! dont waste your mana .
6-18:Ultimate is just perfect. from 3 atacks u can kill a caster minions without any ability power item.

PROS:
-Tanky
-Tons of Damage
-Best 1v1 in game
-OP if u know how to play him
-Excelent harraser
-AoE Stunner
-easy escape with ,,Leap on minion " trick
-tower killer
CONS:
-Focused first in team fight
-sucks till level 6.

U can steal kills very easy with EMPOWER + lEAP .
example : if u and kayle are ganking an enemy , u must take the kill .
Remember 1: 3-4 Kill steals in early game can make your team to win the game.
Remember 2: a fedded jax = game won
A ks jax may make your team-mates to rage a little but remember that they will be happy when they will win the match ;).
