Procedure

Quest Step	Destination	Notes
-	Mark of Man's Tomb	Make your way to the Lower Level. Walking over a pitfall trap will drop you down a level (but not to where you can get to the next level) and also make your team take some damage. There's a room at the top of the lowest level map where you get a cutscene. After cutscene, 3 exclaimation marks will appear on the lower level map as monsters to defeat. One of them holds a key you need to get to the Sealed Room for boss fight against Demon Lord Genshin.
-	Mark of Beast's Tomb	Make your way to the Upper Level. There will be places where you need to flip a switch to make barriers disappear. Boss fight against Demon Empress Garneli.
