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.
Yeah, this is more an item-build for Shaco not a guide. I take this build when I am jungling.You can customize the items to your opponents. If you need some vampire or Life, you should buy Frozen Mallet or Bloodthirster before your infinity edge. By the way at level 16 you can do solo Nashor, if you have Wriggles, Madreds and Beserker´s ;). So try it and have fun.
