Trials of Piety tutorial videos.
Had to split this tutorial into multiple video files because I was waiting for a monster chest to unlock and didn’t want to waste flags. Links to the first two levels are below but the only level with real difficulty is the last one, which I embedded into this page. Like I noted above, this challenge is very difficult if all you have are 4-star classic heroes. The main strategy of killing Joon with riposte works. However it turns out that Wu Kong and Boril are must have heroes for the quest. Otherwise you will not have enough damage dealing capability to take down the bosses.
