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.
Hey, this is not my build, I copied it from this link: http://leaguecraft.com/strategies/guide/233-twitch-for-to-better-of-make-team-winning.xhtml
I just thought that it was a great build so I decided to put it on mobafire.com so that you could use it, I did change one thing:
I thought that I would go with malady instead of Last whisper and I personally like that better most of the time but if you are facing a hero such as poppy or anyone else with alot of armor it would be better to get whisper, but it is a personal choice!
I really hope you like this build and comment on it on this page but also on the link I got it from.
