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.
When playing as Jhin you must play like a sniper. Jhin is really Op long range champion these items are tested and its really broken. Trust me you don't need boots for Jhin the Ghost Blade will help you from escaping plus your passive for the movement speed.
Also add me for more secret guides about Jhin.
Just remember these builds really works so well
