The main appeal of the dungeon is the interactivity of it all. You get to make many different meaningfull choices which actually change stuff. You can side with one of the 3 mini bosses giving you diferent npc to recruit later to your wayfort. There are Idk how many different bad ends if your into that. You can corrupt an npc. All that stuff.
Try to look around. Try different things.
Yep this was my bad, I missed the side routes and just went straight to the main boss. I didn't realize you could go left or right.
Is there any content post dungeon? They say they are now under my control but I don't see the corrupted lupines?
