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.
I usually use Master Yi as my main champion and ALWAYS use this built which works pretty good with me. Wuju Style is very helpful and you can get very early First Blood with it. Once you have the built done until Frozen Mallet, you're pretty much OP and no enemy will be able to escape with this super fast, strong Master.
