Final 2 Items (Read Notes)
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.
You shouldn't need a guide on how to play Shen or LoL as a whole and too many guide writers do that but I'm just going to stress one thing, my build path and strategy below:
In short, after getting Sated Dev, CDR Boots and Sheen at least your combo looks like this:
(AA twice before fighting), then E -> Q -> AA -> AA -> Pause for Sheen/Tri CD -> W -> AA
Essentially you're stacking damage and all your item passives for a large burst of damage. (With Thunderlord's, just do the same combo, you'll trigger it on the first Q AA and last as well)
That final AA will be a Sated Devourer, Sheen/Tri Spellblade procced empowered Q AA.
Credit to TheDirtyGuvnah for the build in his duellist Shen guide, he should take credit for everything I've written here. I just wanted to bring my personal item build path choices and the little duelling mechanic thingy to light for more people to try out.
