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.
Tried this build for ***** and giggles.
It actually leaves you pretty tanky with decent armor / magic resist and vorpal blade, feint and stand united do some pretty beefy absorbs and damage.
All-in-all just play like regular shen... with Ability Power.
I went 12-4-14 with this build in a ranked match.
