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.
Simply with this build expect to get alot of kills with your poisons when enemies run as well as random kills from your shrooms that absolutely nuke anyone who steps on them in the jungle. Make sure to put shrooms in the bushes around you so you can always see in the bushes. If the bush is not in the jungle but against an outside wall, put the mushroom as far from the wall as you can while still being in the bush. When trapping in the jungle don't simply put mushrooms in the middle of an opening unless you just want to see who passes that opening, but to hit them you need to put it against a corner so their auto run takes them rite into it. (you can also line them up about 100 spaces apart, and if an enemy is stupid enough they will kill themselves in 2-3 hits from max health)
