It's all black to me
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.
It is scientifically proven that this build is up to 267% stronger on Lucian and Karma for unknown reasons, and about 169% more efficient on Nocturne. Other champions are viable with this build too, even though it is not optimal.
The Black Cleaver is essential for this type of playstyle, because it is black (even though it is white).
