Delubrum Reginae is a large-scale duty in Final Fantasy XIV: Shadowbringers, released in patch 5.45. Part of the Save the Queen Save the Queen storyline, it is a variation on open dungeons and has no role restrictions, and once inside players can freely leave and join parties as they choose. 24 players can challenge the normal mode, and it is the first such duty to feature a higher difficulty Savage mode, which can be challenged by 48 players.

Unlike prior open dungeons, Delubrum Reginae is not contained within a larger open-world instance, and once unlocked can be queued for freely, though it uses the same Resistance Rank and lost actions system as The Bozjan Southern Front The Bozjan Southern Front.


Misija has retreated into the heart of the Bozjan ruins─Delubrum Reginae. Once a shrine to Queen Gunnhildr, brimming with light and life, its halls now play host to creatures of the dark, warded by foul traps and snares. And it is there, with Save the Queen in hand, that Misija would see her plans to fruition. Now it falls to you to brave its depths and at last put an end to her misbegotten schemes.

Duty description

Thanks to a vision of the future, Mikoto and the Warrior of Light are able to track down Misija, who has taken a detatchment of soldiers within the ruins of the Last Trace. However, this is revealed to be a trap, thanks to Misija's Resonant abilities, and she leaves the Resistance group to fight against IVth legion soldiers while taking her tempered Blades deeper within. Mikoto and the Warrior are able to break free from the struggle, and pursue her.

Savage Preparation[]

After clearing the normal version of Delubrum Reginae and the story quests, players will be able to unlock the more difficult Savage version by obtaining Resistance Rank 15 and possesing 2 million mettle then speaking with the Troubled Gentleman NPC in Gangos. The Savage version of Delubrum Reginae hosts extra encounters and more difficult versions of the bosses from the normal version. It also follows similar rules to the baldesion Arsenal, preventing normal revives on K.O'd players unless done through the use of specific Lost Actions or Healer Limit Break level 3. Savage also allows for a maximum of 48 players to join, though the health of bosses scales accordingly for lower numbers. Upon full raid K.O. all players will be forced to leave the instance and re-enter to start from the beginning.

Musical themes[]

"The Sochen Cave Palace (Zodiac Age Version)" plays throughout most the duty. "Giving Chase (Zodiac Age Version)" plays during the battles with the Trinity Seeker, the Queen's Guard, and the Trinity Avowed, while "The Queen Awakens" plays during the battle against the Queen.


Chests throughout the duty will reward players with Bozjan silver coins, and have a chance of dropping field records. The final gold chest also has a chance to give a hairstyle and a mount. After completing the duty for the first time, players can speak with the Resistance Supplier in Gangos to rade Bozjan silver coins for gold coins, which in turn can be used to purchase item level 510 Law's Order gear.

Behind the scenes[]

Delubrum Reginae is Latin for "Queen's Sanctum".

The entrance to the dungeon is hidden in a chamber within the Last Trace in the Southern Bozjan Front. This chamber can only be accessed once as part of the story.
