Detailed checks from the original evidence

  • From the Temple of Blue Fireflies Bell, go through the fog in the shrine, which requires collecting all 6 of the Fireflies Memory Flowers to open. — Phantom Blade Zero Village of Lu Collectible Locations(PowerPyx)
  • This enemy apparently drops a Memory Flower, but they didn’t drop it on my playthrough. — Phantom Blade Zero Mandate Encampment Collectible Locations(PowerPyx)
  • Petal x/y reflects the collection progress shown in the recorded pickup sequence for that memory.

  • This story tale is accepted when collecting one of Firefly’s Memory Flowers in the Village of Lu. — Phantom Blade Zero Trophy Guide & Roadmap
  • The northern part is actually the 8th region called “Mirage Estate“, which is counted toward the Pangzhen map progress — Phantom Blade Zero Pangzhen Collectible Locations(PowerPyx)
