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 is the build I use with cho this is my second attempt at makeing a build for him and this one works much better. You should be able to keep your more squishy teamates safe while you soak up most of the damage. I usually just use feast on minions unless I can get a easy kill. If you have any ways I can improve this plz tell me. Thank you.
