Final Fantasy IV: The After Years/Challenge Dungeon

Challenge dungeons are a new addition to provide additional, higher-level gameplay for each chapter. After completing a chapter and reloading your save data, you may scour the Blue Planet for Namingway (now calling himself Challengingway) to gain access to special challenge dungeons with more powerful monsters. After clearing the dungeon, you will have a chance to get everything from simple monster item drops to very rare items, armor, and weapons. These dungeons can be played through multiple times, each with a different item distribution and another chance to net more rare items.
