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.
so first off, people will probably say that picking wither first off is a bad plan, but with early ganks, it is god. mixed with exhaust, you will most likely kill two, maybe three people in 3v3. this build is for 3v3, so i don't know how in 5v5 it will run. the trinity force is the best item in game for him, and that is indisputable. mixed with his siphoning strike, which you will want to last hit with a lot early, so that he will be doing max damage, he is god. ive gotten three kills in a row with this not even half of this build. anyways, i hope this build works for you, and HF and GL playing nasus, the curator of sands!
