I had made this build on a whim after looking up a few different builds for Jax. I hadn't played him in a long while and was looking for a reason to start up again. Imagine my surprise when the build worked. After building only one of his core items completely, I had become the scourge of the opposing teams nightmares. This Build is meant to bolster every aspect of Jax rather than just one, so be ready to reap some serious havoc as the purple berserker. I give you, Jax.

Your main core items for each build style are going to be Berserker's, then Hextech, then Guinsoo's, the Trinity. The BG work well with the passive from Jax R. Hex and Guin damage output extremely high, especially if you can accumulate that much gold early. Guins Passives will stack with Jax Innate causing his AS to sky rocket after a few hits. Once you have Tri, Jax will be a huge threat to all who oppose him, And will be enough damage to carry your team well into late game by itself.

Choosing Defensive: style will increase your survivability in late game.

Choosing Offensive: will make Jax a full blown Carry, but takes more to keep from dying if ganked. Most of what will keep you alive is life steal and spell vamp at that point.

Hybrid: is a bit of both O and D.

Experimental: Gives durability with GA, but then is meant to optimize JaXs passive. with a High Attack speed Item

Pros: Mobile, Has own stun, Very hard to kill, supper strong early mid to Late

Cons: Reliance on Mana, hard to achieve a kill before level 6.
