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.
Thats how I did 11 0 20 on ranked game :)
Also don't forget Brand's combos.. Use E-Q-W and if you are sure that you will get the kill use your ulti. But ulti is more usefull when enemy ablazed and have some another units around him. You can also carry with your ulti. If your ally tries to escape go there and ablaze enemy with W than use your ulti. There is a probabilty that you can get some kills.
I also did Penta with this build. Please vote and comment
