Return for the statue chest
After the second-floor Liquid Flame/Iron Giant encounter, solve the chest’s three-statue sequence for Tyr’s Armor. Read the route by floor. This optional chest is separate from the story’s Tome and Psyche return gates.

Main route checkpoints
- Follow Lid’s story detector to locate Mysidia. Hidden-treasure radar upgrades are not required for this initial search.
- Get the special medicine from northern Mysidia, beat Wind-weak Slagworm and deliver to Sunioo.
- Clear both Nameless Ruins guardians: Lightning magic for Iron Giant, Water/Ice with Reflect awareness for Liquid Flame. Let the introductory Tellus event conclude.
- In Arcane Library, open and defeat all five haunted books. Use the restored teleporter and obtain the separate tome beyond Byblos.
- Explore the first Psyche visit, inspect the required gate/cliff scenes and leave through the book. Complete Tower of Mysidia’s summit memory event.
- Return for the second visit with recovery on an available actor. Finish forest/camp conversations and flowers, then Dark Fina and Tellus; return to Sakura’s house.
If progression seems stuck
The first memory visit deliberately cannot open the whole route. A missing tower-memory condition is not a hidden physical key.
