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 guy is crazy and this build takes advantage of everything he have and add some stuff that he don't have. The main dangers for him are coming from a heavy cc enemy team, this is the reason i would use Cleanse and Banshee's Veil, besides that he might survive even in a 1 vs 3 battle, with his ulti on.
Other options: it might be a bit to risky to chance with 2 items that are only good when u have stacks on them, may change sword of occult for a Sheen, and later upgrade it to Lich Bane, this also give u 7% movement speed, not 15% like a full stacked Sword of the Occult but you don't need any stacks. :D
If things are good for you and your team, or there are not heavy cc enemies, then Banshee's Veil is not needed, change it for Zhonya's Ring, or if there are casters but not cc's get an Abysall Scepter or a Force of Nature. Change Mercury's Threads with Ninja Tabi if you need armor and dodge, or with Sorcerers's Shoes if you like magic pen. Heavy ad enemy team means also that you may have to change Warmog's with Randuin's Omen, Thornmail or Frozen Heart. I like Randuin's cuz it also beaf you life (and with Atma's also you damage) and give some (not much) life regen.
Please leave comments, what you think of this silly build? :D
