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.
Just try it
My friend asked me to make him a jax build so this is what I could come up with. You are all welcome to try it I've only played Jax a hand full of times so I don't have 100+ games with em. I did well with em when I did use him. Please leave a comment about this build and any suggestions that would be helpful. Thank you for taking the time to look at my build.
