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.
Hey, guys. This is my first build and I believe this is one of the greatest Teemo builds you can use. :D
Feel free to switch around anything, but I'm usually able to build my Deathcap fairly quickly. If you'd like, build your Lich Bane first, or your Malady, since it's cheaper.
I use teleport just to move around the map more quickly to help my teammates and such. You could change it to flash, I suppose, to catch up more, even though you have ghost. It's all personal preference, imo.
