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.
How to play.
Make sure to engage the battles but get out alive to regain ur HP for the next fight.
Ur HP regain and high HP is ur greatest wepon but dont get to agressive, he does have a high dmg output but cant take down multible enemys alone. I would say garens great offensive wepon is his ultimate. You will be able to dive people with low HP under turrets cuz of it.
