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.
I will include a more detailed build later, but until then:
My build is a Hybrid build that increases your survivability with Life Steal, and Spell Vamp, while also giving you higher damage output with all ability not only because of the high damage and ability power, but also with your crit strikes. I soloed baron on this build easily, not even having to worry about my health.
At the beginning of the game, try to harrass a little bit, but not enough to get you murdered by the other champ/champs. This build is expensive, so don't let the other team zone you out of exp and gold. If you can stay off the turret, do it, because otherwise, its stealin you gold. If you feel you can help gank mid before you hit six, do it, it will help you later. Do not try to do anything heroic at this point yet though, because you do not have the survivability that you will have late game.
When you hit lvl 6, go out and start ganking. You should at least have your Hextech Revolver by now, if not your BF Sword. To gank, you're going to want to hit Empower before you enter combat, Leapstrike, and then if you can, Stun them. By this point they shouldn't have too much hp and you can just smack em down as they try to run from you. You should at least have your Hextech Revolver by now, if not your BF Sword. Gank, and jungle inbetween, to keep up your gold intake, and push towers when they need pushin.
In late game, your gonna want to wait for the tank to initiate without the other team seeing you, to surprise the **** out of them. Once they initiate, kill to your hearts content and push, push, push. Now, as for tower diving, with full build, you can kill most everyone, but unless your hitting someone, your boned. If you don't see yourself living, run for your ******* life, you don't wanna be that guy that dies cause they are too greedy all the time.
Since I really can't think of much else to right at this point in time, My Build description is complete
