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.
I made this build for you and it is for backdooring.
Destroy a turret with full health WITHOUT minion support, simply:
Pop ulti on,
Pop Youmus on,
destroy turret in under 5 seconds,
hide in bush,
teleport to other lane,
If caught, Headbutt enemy flash out and enjoy your 500+ movement speed.
Backdoor Ali FTW.
You should average 7 turrets per game. Enjoy :)
