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.

For this build you will have almost capped out attack speed and very high critical hit which means the more you hit the more chance you have at critical hitting which means more damage which means more kills which means more fed yi which means more awesome :D which means more master rightclick
