AWESOME BUILD! I went 20/7 with it!

Well i'm not really fond of spirit items, but golem is the only i see as viable. But instead of Hextech Gunblade i'd take something with MS/Att speed/AD with HP or def in it, something off tankish or a Zeal/ Stinger variant. Probably Wit's End due to its MR and att speed.

I guess you know that jax with CDR and a Sheen item is hell of a threat, so i would build that Iceborn Gauntlet (or Trinity Force) earlier. Frozen Mallet is not as necessary in the jungle, armor helps more than HP there, not to mention slowing jungle camps won't help at all.

If you take Iceborn Gauntlet before Frozen Mallet you will get some more potential becouse of the AOE damage, and still maintain your ganking potential becouse of iceborn AOE slow.

Just some thoughts i had

Hey, Thanks for the advice. I am fixing the grammer as we speak. Ill work on the formatting when i get the time. I changed the marks to flat Attack damage. Aspd is nice as well i put those as optional in my rune section. What items are you not sure about and do you reccomend anything?

Correct again man. Thanks a lot you really helped me out with the mark runes. ^.^

Well, I picked this spirit item because of the defensive attributes Armor, HP, Tenacity. Mainly becuase the tenacity. This build is a tanky dps Jax. Besides, late game the wriggles won't be as effective as any of the spirit items late. A ward is always good but thats why we have supports. Thanks though ^.^

That's not always seat in stone, just most of the time its wriggle's

Jax is a Wriggles jungler. Spirit items are wrong.

Even flat ArPen wont help too much in the jungle, flat AD or att speed helps much more

Thanks I changed the hybrid marks. Your right there no need for magic pen in the jungle so i went flat armor pen. What items do you think should be changed or aren't needed. I'll explain why i choose them. Thx again.

Thx for your ideas so far I'll make some change tonight

Looks decent. A bit short and the build could has some items I wouldn't get, but still meh. I wouldn't bring hybrid pen marks in the jungle though.

Add more formatting, it's kind of hard to read. You have lots of grammar mistakes too, some work on chapter order would be nice too. But lacks information, not going in-depth.

Your items seem decent, not sure about some but they are decent enough.
However your masteries just dont fit Jax, you barely get any of the good ones in offensive tree, but you go to full depth, thats not goo.
For runes i recommend changing the hybrid penetration for attack speed ones. You should focus more on a champion's basic stat instead of something that won't make big difference.
