The Dankest Shen
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.
Early game is just farm time. You don't have much kill potential unless they take tower shots, ao just try to trade evenly and stay behind your minions. After you pick up your level 6 you should constantly be watching bot lane and ult on your ADC then taunt their ADC and try to give the kill over to your bot laners. Late game you should be split pushing, and ulting into teamfights when they occur. This is why I highly recommend going the offensive route with Sterak's, Titanic, and Dead Man's, as it gives you the best waveclear and dueling.
