3. Walkthrough
Sections In This Chapter
Section 1 — Docks Under the Icy Moon
The chapter opens at the docks under a full icy moon. Visibility is high; combat encounters are denser than usual.
The icy moon gives all Genma a +10% buff. Equip the Stormbreaker Talisman (Chapter 20) to counter the moon-buff's damage bonus.
Section 2 — Frozen Canal District
Tracking Rashō-gan through the frozen canals: 6 Genma Brutes + 4 Byakue officers + 1 Rashō-gan lieutenant.
Follow the moon-shadow on the canal ice to track Rashō-gan's footsteps. The lieutenant is a quarter HP and drops the Icy Moon talisman on death.
Section 3 — Snow-Covered Shrine — Rashō-gan Remake
The shrine at the canal's edge. Rashō-gan returns, now wielding a snow-shrouded twin-blade.
Same 3-phase fight as Chapter 15, but with snow-boosted combos. Use the Aquifer talisman to negate the frost slow-debuff.
Section 4 — Dock Rooftop Pursuit
Pursue Dokyo across the dock rooftops. The rooftops are unstable; fall to a lower level and lose 60 seconds.
Wall-Run Issen (Chapter 9) and Aerial Issen (Chapter 15) are essential for the rooftop pursuit. The pursuit is 90 seconds; falling twice forces a chase-fight in the alley below.
Section 5 — Dokyo Final Showdown
Dokyo awaits at the dock-master's tower. The final showdown is a 4-phase fight against the Genma-onmyoji.
Phase 1 (HP 100–70%): talisman-chain cast. Deflect each talisman. Phase 2 (HP 70–40%): Dokyo summons a Rashō-gan echo. Defeat the echo first. Phase 3 (HP 40–10%): Dokyo enters Genma-form. Lightning + combo attacks. Phase 4 (HP 10–0%): Dokyo's last stand — he casts a doomed-storm AoE. Chain-deflect all hits to break his posture and end the fight.
Section 6 — Hozuki Pouch Ultimate Form
Assemble all 7 Enma Pages at the dock-master's altar to upgrade the Hozuki Pouch to its ultimate form.
The ultimate Hozuki Pouch has 20 slots and a 5-second cooldown on use. It is the most powerful healing tool in the game and effectively trivializes Episode Igniter's difficulty.
4. Key Items & Collectibles
| Item | Location | Effect |
|---|---|---|
| Dokyo Soul Core (Chapter 21 variant) | Final showdown drop | Talisman-chain gauntlet ability |
| Icy Moon Talisman | Rasho-gan lieutenant drop | +15% deflect vs Genma under moonlight |
| Hozuki Pouch ULTIMATE form | Assemble all 7 Enma Pages | 20 slots, 5-second cooldown |
| Hozuki Pouch token #18 | Hidden in frozen canal #3 | +1 pouch slot |
| Episode Igniter unlock | After Dokyo | New game-plus ultimate chapter |
| Sun-Dried Hozuki x22 | Docks reward | Crafting material |
5. Missables
- Hozuki Pouch ULTIMATE form — requires ALL 7 Enma Pages. If you missed any earlier chapter's Enma Page the ULTIMATE form is locked out (the chapters cannot be replayed retroactively for Enma Pages until NG+).
- Dokyo Soul Core variant — killing Dokyo in under 8 minutes grants the variant Soul Core. Take longer and the Soul Core is the standard version.
- Hozuki Pouch token #18 — hidden in frozen canal #3. The canal freezes completely after Rashō-gan's defeat, locking the token.
- Icy Moon Talisman — the Rashō-gan lieutenant must die before he reaches the dock rooftops. If he escapes, the talisman is gone.
