Map of Inferno Zone.
Good leveling up room :Edit
Flame of Fire Devil-1 (murians)
Flame of Fire Devil-5 (mutans)
Secret cave: (Rock cutting sword is not required)Edit
Entrances: Flame of Hell-3; Flame of Hell-4
One of the few places where green minerals can be found reliably!
Notes: Flame of hell-3 entrance in bottom right of area, rock cutting sword required. Flame of Hell-4 entrance is impossible to reach without using skill after doubble jump, but is do able, though not quite as easy as Flame of Hell-3.
