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.
Teemo - Reaper
This is the build I use for Teemo and I felt like I should share it with all of you out there who use Teemo either in 3x3 or 5x5. This build lets you be kind of okay early game and going for more power at midgame. In the end when you have all necesary items you will find yourself hitting so fast and so strong that noone can escape you cause you will have amazing moving speed, attack speed and criticals.
Enjoy your games!
