Here is a good build for jax, (most likely even when dodge is taken out). Nashor's tooth is a valuable item for its attack speed to stack jaxes relentless assault ability fast then deliver high damage ability power at a very high attack rate. The runes of focus are important to jax can be great at chasing for his stuns and leaps. When dodge is taken out resistance/defense runes will be handy. I hope they change jax for the better ^^

The Glyph portion is the nine glyphs of force solely for ability power damage which is included in all of Jax skills. Nine Marks of alacrity mainly for Jax's E stun skill and makes Jax great at chasing with his Q leap skill as well. 9 seals of evasion of course for Jax's E. and last quintessence of Potency for good ability power for beginning game gank.

The masteries for this hybrid build are mostly offensive for a good AP/AS boost, and a couple of defensive boosts.

Malidy and Nashor's Tooth are very important as this builds main items and should be purchased right after boots. There attack speed boosts will allow jax to stack his ult very fast and gain an unreal attack speed to follow up on his powerful third strike ability power damage which will be unreal as well especially with Rabadons Death Cap.

Have OP Fun!
