Diablo and the others were heading to the dungeon to obtain the hidden treasure that can cure the Death Knell Disease when Laminitus and her army surrounds them and attacks. Their party manages to reach the entrance to the dungeon, but there are now six marks on Lumachina's body, and it's said the victims of the Death Knell Disease will die once there are nine marks...
and once you clear it, the stairs 
to the next floor appear.
Si on la réussit,
l’escalier suivant apparaît.
una volta risolti, appaiono le scale
 per il piano successivo.
e, ao superá-los, aparece
a escada pro próximo piso.
Пройдёте — и появится
 лестница на следующий этаж.
