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.
The best things to do.
Start off with a doran's shield, and get berserker grieves. keep those until u need the spot. first of sell the dorans shield and get the second bloodthirster Then sell ur shoes. for the black cleaver.
I Highly reccomend to first kill minions to stack ur "Bloodthirsters" for demage, and life steal.
This build, is great for top or bottom laning, it doesnt matter what kind of champ you have next to you. Caster,Ranged,dps,tank or support it doesnt matter.
