Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Activate your empower before using leap on someone.
With this build, your leap is deadly while being useful to your team
rageblade is a good item, but it isn't the best if you want to make some kills fast! and your ap ratio on your leap isn't 100% your AD is!
Jax is my main.
wait for someone from your team to iniate.
Jax MUST NOT initiate.
Also, Jax is good with ANY build.
You can go TANK jax , AP, AD, Hybrid.
But this build is the deadly one!
