Nightmare Dungeon

Nightmare Dungeons are a series of dungeons in Final Fantasy Record Keeper. The Nightmare Dungeons are a series of twelve groups of four bosses that must be defeated to challenge a Nightmare boss, which when defeated drop a Record crystal that allows the crafting of a powerful 6★ ability.
The Nightmare Dungeons were released one at a time, starting in Japan on September 25, 2015, and globally March 26, 2016.
With the addition of Magicite Dungeons, the player must complete all Nightmare Dungeons to access the Magicite Dungeons.
== Story ==
== Rules ==
The Nightmare Dungeons are presented as a ring of twelve crystals representing the special 6★ ability they seal. Upon selecting a crystal the player sees four portraits of the bosses of the dungeon, with a fifth portrait in shadows behind them. Defeating the four bosses will cause the fifth portrait to come forward and light up, revealing the Nightmare boss to be challenged. The initial four bosses grant Record Synergy for their home realms, while the Nightmare Boss grants it to characters able to use 5★ abilities of the same type as ability it guards. For instance, Reraise is a 6★ White Magic ability, so when challenging the Nightmare boss guarding the Reraise crystal, any character able to use 5★ White Magic will receive Synergy.
Defeating a Nightmare boss rewards a Record crystal needed to craft a 6★ ability. These crystals are unique items, so only one each of these abilities can be crafted; shattering them will return to the crystal, so it can be recreated later. Additionally, characters able to use 5★ abilities of the same type of ability that was won, will be upgraded to be able to equip up to 6★ abilities. 
Completion of all cycles will grant access to Magicite dungeons.
== Musical themes ==
The theme for the Nightmare hall is "The Stone's Secret". The theme for each Record Room is "Infiltration". The theme for each Nightmare boss is "The Barbarians". All these unique themes are originally from Final Fantasy XII.
