Nightmare Dungeon

The Nightmare is a campaign comprised of advanced Records in Final Fantasy Record Keeper. Players wishing to take on the Records within the Nightmare will find battles of exceptionally high difficulty as well as ultra-rare Rank 6 refinement items and other prizes not available in the standard game. This feature was first activated in the global release of the game on March 26, 2016 (UTC).

Status
The Nightmare arena is CLOSED in the global release. 2/12 cycles complete.

Layout
The Nightmare is presented as a ring of twelve dungeon groups, with each dungeon group offering four supercharged boss battles. Each contains one or more items necessary to craft a Rank 6 ability, as well as tickets to the Hall of Rites upon mastery.

However, the nature of the Nightmare is cyclical; it will only remain open for fixed periods of time. If the player should miss any window, s/he will have another opportunity to clear prior dungeons when the Nightmare opens for a new Ability Record. It is currently unknown whether the campaign will reset after the twelfth event, or simply end.

Record Synergies are dependent upon the Record entered, rather than being neutral across the Nightmare. Thus, it may be prudent to develop as many units as needed to maximize Synergy.

Musical themes
The theme for the Nightmare hall is "The Stone's Secret" from Final Fantasy XII. The theme for each Record Room is "Nalbina Fortress", also from Final Fantasy XII.
