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.
this build focuses on stealth kills, that means that in order to kill someone easily you stealth then ravage, then start hate spiking him, when he is killed you must stealth again before you proceed to killing another target, exhaust can be used so that enemies do not escape! make sure that every time you are out of mana you go back to base and restore it or use pots!
