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.
Okay here's one of about a million Jarvan IV builds. it's what I've been using as of late and I'm going to be modifying this as I go along. As it stands right now I am currently 16-0-17 and 10-9-19 (We had to deal with a feeder on our team and a adventitious rat on their team). That being said. I am not going into Items or why I selected what I did as of just yet. All I can say about this build is:
It requires a TEAM. you will do horrible on your own.
