Hellfire Chasm is one of the new Soul of Chaos dungeons added in the Dawn of Souls release of Final Fantasy I. It is an optional dungeon, located among the various Dragon Caves. Access is granted once players have defeated the Fiend of Fire, Marilith.
It is highly recommended that you save your game before entering Hellfire Chasm! It is also highly recommended that you do not save inside Hellfire Chasm, as once you enter, there is no way out except for defeating a boss.
Entrance Area
A lone elf keeps watch over the entrance area and notes that few adventurers will brave the dangers beyond the doorway. If you haven't defeated Marilith yet, you can't continue beyond this point. WARNING: Once you enter the nearby door, you will be unable to return to this area. Also, the White Magic spell Exit and Black magic spell Teleport will not function further inside! Enter the door when ready.
Bosses
Astute Final Fantasy fans might recognize the bosses contained in Hellfire Chasm, as they all previously appeared in Final Fantasy IV (not to be confused with Final Fantasy II). Remember, you may only fight one boss before being forced to exit the Chasm, so choose wisely!
