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.
Once again this is just my Morgana build, it is nothing special but i have had great success with it and wanted to have it somewhere that i could refer to or make changes as i decide i need them. I do not proclaim to be a pro at this i just enjoy the game very much for what it is, a FREE game that can keep me entertained for hours.
