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.
at start you should buy the boots so that you can harase the enemy players and run away quickly you should then buy hextex gunblade it will help u a lot it's very efficient with your ulti because of it's spell vamp u should buy lichbane because of when you use shunpo you can quickly get some bonus damage on that I usually then buy only rabatron deathcap since its only ap and gives you lots of it. end game depending on the enemies team I take out hextex gunblade and put another rabatron. As you can see this is a full damage build you will not have much health . you'd need a good tank to get out with this
