you can use the crystal to see what floor you are (take various directions the crystal will appears when you go up to the 10 floor)
I mean the crystal said I was on floor 8, I interacted with every piece of walls i can. Yet, idk how to unlock the room
I first thought walking behind the book shelf was it (idk if that is a bug or not), but interacting there wasnt it ether
And even did combat for a while too, didnt give me her dna ether like how umbra did
So is it a bug that something ment to spawn in this floor but didnt?
Ps: She the last 1 left so getting the rest was fine
