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.
Here is my first guide on Mobafire :D
It's about Shaco as you can see.
About the items:
Sheen is good for your boxes..and your knife.
For the beginning it's enough AP.
Lifesteal, attack Damage and critcal Hit is the sense of the build.
You play it like this:
Jump behind the enemy, attack first time, throw knife and jump (if ready) before him and attack again from behind, throw knife and so on.
I don't use the runes (not enough influencepoints :( ) but it also works fantastic.
Now have fun with the guide :D
