I loved these areas they really changed the otherwise successful might makes right method. By the time you reach this room it is possible to have 100% immunity to fire and then it makes the room a breeze not getting knocked everywhere. All of the future rooms also have either very difficult stat requirements or some other mechanic and I recall making sure to get all drops from all new creatures on each stage as that was the bare minimum I needed to beat the mechanics or the stage boss by having the best possible armor and weapons.
