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.
i think this build rapes so try it. the key item is manamune, it allows you to harass effectively with spear shot without needing to go back for mana. i dont always do phantom dancer and infinity edge. if i am playing against players with lots of armor then i switch phantom dancer and infinity edge with last whisper and black cleaver for armor penetration. If playing against lots of mages i buy wit's end and youmuus ghostblade mostly for the movement speed to catch up after stuns. im gonna stop now cause this probably wont even get looked at, im just really bored in class.
