The best combo to work on: Shadow Dash, Twilight Assault, and then auto attack.
Shen can quickly turn an enemy gank on an ally into a counter attack with his Ultimate, Stand United. This is a global; use it on a strong carry to shield him and then TP to him for support.
Q: How should you use Shen in League of Legends?
A: Shen is a great tank with good damage potential. He's also one of the best supporting champions in the game. Your Shen build should augment his ability to protect his carries. Shen should Ult to protect carries or Q enemies trying to engage them. If you can outlast your enemies or protect your carries better, you will do better as Shen.
LoL Shen players will find him to be a challenging champ to build out properly. You'll notice that his build changes when he is playing against either generic or highly focused team compositions, showing you shouldn't select the same Shen build every single round of League of Legends
The best items to include in your champ's build include: Sunfire Aegis, Titanic Hydra, and Demonic Embrace. Players who added these items in their kits had a higher winrate than those who went for other item builds for Shen. Likewise, if you are facing a well-mixed enemy team composition, you should really consider grabbing Shen the Resolve, and Domination runes. In recent games, he won the largest percentage of his rounds when built with these runes.
