I see what you did there Kartik 😅😅.
But unfortunately, I cannot answer his question because I haven't reached the end of that stage. I'm only at level 68.
Cuervo the level of dark dungeon advances or become in a stand-still depending on how you finish the recent levels. The game adjust by itself so don't worry about it. If you want it to change in level, play continuously and don't die.
And about how many levels are there in dark dungeon, I have to ask another expert friend besides Kartik... if he's available. But in the meantime, you can still ask Master Kartik for some of your questions in the game. His knowledge is very valuable :-)
