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.
Welcome to my first build,
First start Blue, then go Krugs, then Red (If u can gank someone in between try it) after that chickens if u dont have enough gold search for a gank or get wolves and grump.
Focus in Teamfight
Your only focus is to kill the squishy carrys so ur team can go and do the other champions. only go in when ur at least 99% sure u can kill them or atleast burn their summoners. Shaco needs timing just keep playing and practice.
