Jarvan IV Build
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.
This build heavily relies on you getting fed early and snowballing the game. Coming from the jungle, jarvan has a really easy time ganking lanes and you should abuse that to help your team get fed or get yourself fed. You will notice a huge damage spike once you have completed black cleaver since you would have 35% cdr allowing you to use your ultimate to your hearts content
