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.
How to use this build
Look for picks. 1v1 is your specialty. The on-hit items synergize with your passive and W. Use E to engage and then exhaust to stick to your target. Try to get Glimpse of the Void. It is extremely powerful on this build because of the magic damage it deals and the 1v1ing damage modifier. You will absolutely DESTROY turrets. Go for turrets any chance you get. Hope this guide works for you and I will see you on the rift!
