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.
Now I've played Shen now a lot and very often and out of all the build this one is the most fun and brings a lot of extra DPS most tanks don't bring.
Boots 3x Health potions is the best start for Shen in ANY build in my opinion
It is geared way more towards physical DPS enemies though I did add the Warmongers and Spirit Visage at the end if you make enough money or the game last long enough to get them.
The 3 Sunfire capes total vs most Magic Defence about 90 dps and in team fights that's a lot of AoE in one Taunt ~2 seconds vs 3-5 people that's 540-900 damage in 2 seconds! If they have roughly low Magic Res
But like I said this build focus on Anti physical DPS So Ashe, Jax, AD Teemo, AD Sion. Those are some of the ones that come to mind
But take this as one players opinion to another Shen is one of my favorite tanks to play and his items can go many ways this way just plays against physical DPS as they tend to be glass cannons and the extra DPS help bring an entire team down while your Allies Dps them down to dead
I would also like to add if 2 capes is working the 3 is not needed and you can move on to your Warmongers and so on
I've also tried multiply Warmongers it all just depends on what your fighting so take this guide and learn what works for you!!
