How to Start The Hidden Isle Quest
To begin The Hidden Isle quest in Octopath Traveler 0, interact with the book lying on the floor in the Skies of Vanity during the Bestower of All: Ch. 8 At Journey’s End quest.
The Hidden Isle Walkthrough
A mysterious voice echoes throughout the Heavens and guides you to the place where the rings were once sealed.
Head to the Isle of Orsa
Next, travel to the Isle of Orsa in The Middlesea. Once there, head to the northeastern corner to reach the Isle of Orsa: Depths. Work your way through the north-central part of this area to arrive at the Isle of Orsa: Altar. Enter the hole underneath the altar to arrive at Isle of Orsa: Underground Altar.
When you arrive, approach the altar a cutscene will trigger and the four maidens will give you one last blessing.
Head to Agapea
To find Agapea, head west of The Isle of Orsa. After you dock, head up the stairs to trigger another cutscene. Once it ends, continue north and speak with the Shrinekeeper Ataraxia.
Afterwards, the quest will complete.
Second Flamebringer’s Trial
If you speak with Shrinekeeper Ataraxia again, she’ll mention that your ring is not at its full potential and that you must return to the Flamebringer’s Shrine. Return to this shrine in the Woodlands Region, then head to the very north and interact with the reflection pool to begin the second round of trials.
For this trial, you will face Aelfric the Flamebringer and the Great Flame. The Great Flame has a ridiculous amount of health and only takes 1 damage each turn. It will also remove any buffs that you put on. Once you kill Aelfric the Flamebringer, the Great Flame will bring him back, beginning the next phase of the fight. This will occur twice, for a total of three phases. Aelfric will use strong magic attacks targeting the whole party or single party members. Among the three phases, he’ll be weak to daggers and dark magic for all three.
Phase 1
| Enemy | Shields | Vulnerabilities |
|---|---|---|
| Aelfric the Flamebringer | 14 | Polearm, Dagger, Bow, Fan, Dark |
Phase 2
| Enemy | Shields | Vulnerabilities |
|---|---|---|
| Aelfric the Flamebringer | 14 | Dagger, Axe, Tome, Wind, Dark |
Phase 3
| Enemy | Shields | Vulnerabilities |
|---|---|---|
| Aelfric the Flamebringer | 18 | Dagger, Fan, Ice, Wind, Dark |
After you face the trial and emerge victorious, the illuminating power of the Flamebringer’s ring will grow stronger.
