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 done to a high speed cutting crits every hit. and run faster then anyone on the map rofl.
START: I get the gloves critr. then buy a boots of speed to give you easier to move. Try and stay on track as long as possible. When you finally get back to heal and buy, buy your boots (I like ninja, but mercenaries are sick, if you're facing a lot of stun or spell).
MID: You should now be ending phantom and may start fighting with your team. try to stay behind the team and turn to fight and guide the weakest champion. After fighting a couple of the team or a little more agriculture begin building your ghosts (twin). These will help you farm like crazy and crit like crazy.
END: that way you can help your team to protect his lane, and kill the other champions .... Sorry for the wrong edit ... I'm new here and did not know yet cmo change things .... I hope you enjoy the build, good game everyone!
