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.
Shaco is a great hero. But now because of the nerf on him he is much harder to play. There is a whole bunch of noobs running around dying and this ending with you losing the game.
Well for starter thanks to the nerf Bloodrazors has never been so important. This is because if you have a **** team and have lost exp from failed ganks you are still able to walk into jungle tearing the creaps apart lvling you at a fast pace.
Although Shaco can farm and push lanes like crazy still he is more like an assassin now eg. Twitch or Eve so ganking from early on has become very important.
At the start of the game go for the Lizard buff. This is because if you kill the lizard with your boxes and the two little lizard you get to lvl 2 and the red buff. Now you can simply jump into a lane to the unsuspecting champion and get a nice first blood for yourself or a team mate.
