The Queen's Domain bosses in order run Shrine Guardian, the three Royal Orbewa Guards, Dagoom the Sea King, the Necronomicon, Poenir and Duenir, Josami Lord Saijha, the Gigantic Serf, the Herald of Okbujo, the Blood Angel Lords, Usunha and Wujomiod, and finally Queen Siraatsu. The first four are strictly gated, and after the Mausoleum the map opens up so that five of the remaining fights can be done in different orders.

The Queen's Domain bosses in order

  1. Shrine Guardian, in the Endu Shrine on the starting island. Beating it gives you the Holy Sword Endu and the first Wind Gem.

  2. Royal Orbewa Guards Yepo, Erda and Wami, in Obmuer Temple. All three have to die before the boss door opens.

  3. Dagoom the Sea King, behind that door in Obmuer Temple.

  4. The Necronomicon, at the top of the Tower of Knowledge.

  5. Poenir and Duenir, deep in Deimpo Mausoleum.

  6. Josami Lord Saijha, in the Ancient World, guarding the road to Siraatsu Castle.

  7. The Gigantic Serf, in the Rotting Cavern.

  8. Herald of Okbujo, in the Record of Sin.

  9. Blood Angel Lords Yuumed and Woyeki, in the Forgotten Dungeon behind the big red door.

  10. Usunha and Wujomiod, in the temple in Verdant Hollow.

  11. Queen Siraatsu, in Siraatsu Castle, after the three interior bosses are cleared.

The boss guide has the tactics for each one.

Which order is actually forced

The first four fights are hard gated: the Shrine Guardian opens the rest of the island, the three Royal Guards open Dagoom's door, Dagoom opens the way to the Tower of Knowledge, and the Necronomicon opens the road out to Deimpo Mausoleum.

Past the Mausoleum nothing is forced. Josami Lord Saijha, the Gigantic Serf, the Herald of Okbujo, the Blood Angel Lords and Usunha and Wujomiod can all be taken in a different order depending on which areas you have unlocked, and Queen Siraatsu is last in every route.

The opening walkthrough shows the route that forces the order.

How far along each fight sits

Eight of these bosses have their own achievement, and the share of players holding it shows how late each one sits:

BossAchievementShare of players
Dagoom the Sea KingTreacherous Baleen47.0%
The NecronomiconHell Transcribed34.3%
Poenir and DuenirDemonic Servitude21.3%
Josami Lord SaijhaSworn Protector12.0%
The Gigantic SerfBeneath Rotten Waters10.4%
Herald of OkbujoDread Silver9.5%
Blood Angel Lords Yuumed and WoyekiFallen Angels6.8%
Usunha and WujomiodWake From Dreams6.0%

The Shrine Guardian and the Royal Guards have no achievement of their own, but the Holy Sword Endu that the Guardian gives is held by 74% of players, which makes it a better early progress marker than the first boss itself.

The area unlock achievements

The same order shows up in the achievement names that mark each area opening, and those are the cleanest way to read your own progress:

  • Obmuer Temple: Ocean Walk
  • Tower of Knowledge: Endless Pages
  • Deimpo Mausoleum: Unsealed Tomb
  • Ancient World: Genesis
  • Siraatsu Castle: Halls of Hatred
  • Forgotten Dungeon: Dark Silence
  • Verdant Hollow: Sacred Groves
  • Rotting Cavern: Deep Swamp

The Tower of Knowledge walkthrough covers the third of those areas.
