We already know that dungeon atleast has 70 floors confirmed. And there are 4 confirmed monster rex so far Goliath (lvl 4) on floor 17, Amphisbaena (Lv5) on floor 27, Udaeus (Lv6) on floor 37, Balor (Lv7) on floor 49. So following the pattern there should be a lvl 8 monster rex on floor 60. So what are your thoughts on it?
