to start. you need cloth armor and 5 health potions. once that is accomplished start at blue. make sure you get a good leash or else your jungleing speed dramatically decreases. You dont need a strong leash. but its recommended. after that get wolfs. then ghosts. then red. do golems after. feel free to kite the buff until your stun's cd is done.

When you gank as jax make sure to pop your stun in mid flight of your jump. this gives the enemy your ganking about 1/2 of a second to respond and flash. If you have red is a 88.6 % chance of them dieing . Jax is a strong tanky jungler who closes gaps and makes the team want him to be nerfed!. If your ganking is succesfull feel free to just wonder the map for kills . but make sure you have buffs to back them up. it increases the chance of getting a kill by 43.73%.

Once lane phase is over. you should have wriggles full boots and a hexdrinker. hexdrinker is an amazing item on jax. it makes him able to be tanky and do high damage. so with those items you NEED to close the enemy mid lane DOWN! whether its relentlessly killing them or knocking their turret out in 5 minutes. jax can solo dragon at level 7 , so make sure you take advantage of that.

Jax end game closes off a little bit if you arent fed. but you are the tank and engager. make sure you pop your ultimate once your stun / dodge has worn off. that will make you have roughly 200 armor and 187 MR . this makes you and extreme problem and forces the enemy team to focus you for your such high dmg from the atmas impailer hextech gunblade and maw of molimortis. Too bad they cant kill you due to the 3600 hp and the high amount of armor and MR you recieve from your ultimate. Once you get your hextech gunblade you can easily solo barron within 1 minute. But its always good to have a team mate help you demolish that ugly beast.

BE WERE the enemy will talk consistant trash with you being so tanky and having high dmg output. Have fun! And remember. HAX ARE FOR JAX!!!
