I was playing with jax and then my build became weak and i get ****ed easily but with this build ... for more than 3 games inrow 25+ kills and about 8 death .. Thank you :D

outdated :s

Its outdated, might want to update it or delete it? The build is fine, but remember it isn't a chat room, it's a guide. Telling people what to do. Delete those smilies. Even though they're fine in the introduction. Cheers!

Nice build i just went 30-6-6

Masteries are a bit wrong IMHO,so take a look a this:

The rule of thumb in these cases is to sell your doran's item when you need the room and health from it is no longer crucial. In this case, you sell your Doran's Ring to make room for your lich bane and deathcap. When reaching late game item purchases, you often won't be able to buy more than one component of an item before you run out of room. When this is the case, you simply will have to save enough gold to complete the item in one shot.

As a side note on the topic of item slots, Selling your Doran's item before it obstructs your 6th slot is usually good since it will open up a slot to continue carrying wards while building your 4th or 5th items. Warding is a critical part of all stages of the game and should not be neglected by any player on a team, regardless of their role. This is especially true for Jax, since he can use wards as an escape mechanism with his leap strike, and he will be moving around the map quite a bit anyways to either gank or push/backdoor towers. This means you won't be going out of your way when placing wards, and they could just be the difference between killing a tower and getting away safely, and dying to a 4 man gank.

One more note about buying items. The builds listed in guides are just that: guides. They are not rules set in stone. If you find you have enough sustain with just the hextech revolver, but you are getting bursted down in a teamfight, it might be good to get a giant's belt before finishing other items. Or the opposite could be the case, where you are doing so well and go back and have a large pool of gold to spend, it might be worth it to grab a needlessly large rod much earlier for a big boost to your damage, making it that much harder for your opponents to put a stop to your out-of-control rampage.
I hope this answers your question, as well as being helpful in general.

Feel free to +rep me if anyone reading this found it good or helpful. Happy hunting. :)

Great build. Havent played Jax in awhile and went 23/4/19 using your build. Even got a triple kill. Great job. :D
