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 Shen is a little more dps than a tank but still a decent tank. Guardian Angel for those team fights that you will live through. Warmogs for the nice HP regen and health. Frozen Mallet for the extra damage and more health. Ninja Tabi for the dodge chance and the armor. Randuins Omen for a bunch of things.. armor, HP regen, health, cooldown reduction, and a nice passive. Atmas Impaler so you can do some good damage with all the health you will have by then.
