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.
Ok so here's your strategy, keep farming until you're lvl 18 and have 5 zeals and boots of mobility then go up to there base. Then really quick hit ghost and power ball and charge into there Nexus as fast as you can. Make sure your over 1200 speed or it wont work. Then hit there nexus and watch the fireworks.
Now you can laugh as the other team is QQing about your OPness.
