100 floors of pure fun. Out of all of those locked dungeons that one and the Daurell one were the worst in my opinion. Steyliff took me 4 hours to do and the Daurell one had a ton of those crab enemies that could one-shot you. :/
I started at 6 and it's now just gone 10, so it's taken me about 4 hours as well. I heard some of them got long but I didn't expect that long, lol. Was it really only 100 floors? At one point I was beginning to question if I'd walked into a procedurally generated infinite dungeon v_v
