Master Yi Build
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 builds is decent armor pen with max armor reduction. While still keeping the raw AS/crit needs of Yi. build also works with Irelia,jarvin, and more ADs that i haven't tryed yet.
IF you want to drop towers instead of people swap out Phantom dancers for last whisper(with final his AS is pretty much capped without Phantom dancers
