This is the order, but the progress depends of your luck with the objects, the altars and the potions table chance.
If you dont have good stats in the 10 Room wou will be easily killed, this is the weakest werewolf of the dungeon e.e
The sacrifice altar is so usefull but if you have the chance to heal yourself later, the demon altar can give you good stats but will lose some of other one.
If you dont get objects will be hard to stan, the objects is the priority to give you more chances in battle.
This are some tips so you can complete it x3, i dont remember the life of many characters, but remember the life of the dragon, 2500 xp, but if you reach it with good defences you is passable e.e XD
