This build is good for quick kills and to carry your team , but make sure you don't just run in and die o.O" lol well.. start off with Leap Strike and then at lv.2 get Counter Strike but keep in mind that you'll be maxing Leap Strike 1st.

Leap Strike and Counter Strike are the 2 main keys to this build when it comes to kills due to if your enemy is running you can use Leap Strike then Counter Strike to stun , by the time there out of stun you'll have Leap Strike again as well as Counter Strike so you'll have a sure kill.

Empower and Relentless Assault will come in handy when you dont have CS and LS (Counter Strike and Leap Strike) due to the mass dmg Empower does once its maxed and you have phantom dancer and Guinsoo's Rageblade. also keep in mind dont use Empower or Relentless Assault until you must.

and now since i cbf typing anymore ima post some Trivia on Jax cyaa's and i hope my 1st build helps you as much as it does for me ^^, LOL ok now for the Trivia.

* It seems Jax's character design could have been inspired by the Teenage Mutant Ninja Turtles, due to his three fingers and his two toes.
* His traditional weapon, the lamp post, may have also been inspired by the TMNT. It bears much resemblance to the lamp post used by the TMNT to travel back in time in their motion picture "TMNT III: The Turtles are Back... In Time".
* With the two notes from above in mind, while keeping true to lamp post's lore from the TMNT movie cited, it's open to speculation that it may be possible one of the turtles traveled to the LoL universe using their lamp post to compete, or perhaps by accident.
