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's my original (I think) build, never seen anyone more to use alike, so wanted to place it somewhere for other people.
Item selection my vary in case of how much You're killing in early game or against whom You play.
Basicaly it's build for anyone who wants to quickly jump/splash/kill enemies, not for survivors or supporters. But I think it's why we like Kassa ;).
Hope You enyoj my Champ,
