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.
This is a basic guide, remember to get items according to their team, if there team is balanced with ability power and attack damage, get this guide, you will own and win, depending on how well you are (if you are doing godly which I normally am), max out leap strike first, just get one level of empower, and the rest of counter strike. Please try the build before you rate it. Only get Doran's Deathcap if you are experienced, and know that you will be able to survive out of stick situations.
