Citadel of the Fallen Daeva walkthrough

The guide's lines in the Exploration run, in the game's own order (NpcTalk rows PD_DaevaCitadel_…_NPC_<n>).

How it's counted

Bosses are listed above in the order this route first names them.

  1. 1

    Bind with the Kibelisk, kru. A mighty foe awaits!

  2. 2

    I see Turgen below, kru. Go on, glide down!

  3. 3

    An Updraft appeared! Hop in and fly up, kru.

  4. 4

    Those blades look nasty, kru! Move carefully!

  5. 5

    Let's deal with the beast outside first, kru: the forbidden hexbeast Griosa.

    But first, bind with the Kibeli—oh? You know the drill? *Ahem* Then bind with it, kru.

  6. 6
  7. 7

    Nice one! Now let's head back and open the gate, kru!

  8. 8

    No path? No problem! Trust me, just jump down, kru!

  9. 9

    A bridge appeared, but it looks like it's about to collapse, kru!

    Get across before that happens, kru! And watch the blades!

  10. 10

    You need to get to the bridge up there. Use the Updraft, kru.

  11. 11

    You know the drill! Run across before it collapses, kru!

  12. 12

    Whew, looks like it's just about over, kru. Let's head inside.

  13. 13

    The final foe stands before you, kru. Let's go bind to that Kibelisk.

  14. 14

    Look! An Odyle Energy Cube, kru!

The guide's briefing (8 lines)

Oh, is that you? I've been waiting. Been admiring the scenery of this citadel in the meantime.

I'd heard there was a natural fortress standing in a mountainous area somewhere, kru. You can definitely feel the strength of the Daeva that faced the Balaur here.

But there's also a more ominous energy lingering, kru... Maybe it's because of the fallen Daeva.

At the time of the invasion, Balaur swarmed with no end in sight, kru. The Daeva were cornered and fell back on their last resort.

Indeed. Dark magic. They managed to fend off the Balaur, but paid a heavy price, kru.

It cost them their honor and their souls, kru. A rather cruel fate, I'd say.

And so here they are, waiting for an honorable death. Seems we might be their only hope, kru.

Right then, let's set them free, kru. Let's take this expedition on!

How this page is made

Game files (client 2026.10.21 (Steam build 26077854, 2026-10-21)): the lines the game shows when a boss casts or uses a skill, gets a buff, starts or dies (NpcBehaviorCase → NpcTalk: “Guide” = the Shugo guide's hint in the Exploration run, “Boss” = the boss's own shout), the skill's name, cast time, cooldown and range (Skill), the buffs and debuffs it applies with the game's text (SkillEffect → SkillAbnormal), the Frenzy timer (NpcData.BossBerserkInvokeTime) and the stagger. Many boss skills are only called “Attack” in the files; those cards are named by their effect or by the action they ask for. HP thresholds are not in the client.

The action label on each card is our reading of the guide's line, by its words: the first that matches of “Big alone, small together”, “Stagger it”, “Stop attacking”, “Break free”, “Climb up”, “Jump”, “Take cover”, “Block it”, “Lure the boss”, “Colours”, “Kill it first”, “Stack up”, “Spread out”, “Find the gap”, “Get in”, “Move out”, “Burn it down”. The line itself is the game's.
