This is my second build ive come up with and its what ive been using recently to have more fun with shaco. Its for experienced shaco players though. Near the end of the game ive had below 100hp and got a quad kill because i had 75% life steal, 96% crit chance, and my attack damage was 399. (All after the bloodthirster buffs) I literally was almost completely full health after ONE attack on the first champ! So if that kind of domination is the kind you want then USE THIS BUILD!:)

Early game it is good to play conservativly and to kill as many creeps as possibly to make as much money as you can to buy your first blood thirster after bersearker greives.

Mid game you should have your berz greives and blood thirster and at least half of the first phantom dancer. At this point you should kill as many mins as possible to get the most out of your blood thirster buff. Youll notice that your doing way more crit hits.

End game you should have at least 2 blood thirsters and 2 phantom dancers along with your boots. Saving up for your last blood thirster is easy here. Around this time youll notice that shacos skills are barely used for kills. I use deceive to ambush the enemy, immediatly use my shiv to slow the target, immediatly drop a box in the direction the enemy might run so that they are feared back to me, and possibly use my ult. Within 3-5 normal physical hits should kill ANY target late-to-end game.
