A post for the completionists among us: Are there more than the five EX episodes that I discovered (Adenia, Kinshicho, 2x Nirvana [Mido and Hemera] and lastly - after completing the game once - Tartarus)? Also, I managed to obtain 62 Phantom Cores, which means I'm confident I didn't miss too much of them (a lot of them are permanently missable).
There are a few loose ends, though - in particular:
- Adenia Robotics, weapon development factory: One NPC here mentions a gunsmith at Mt. Azure, whom I didn't manage to find.
- In Adenia (main area, western part), the NPC in the building on the second floor refused to acknowledge my demon slayer achievements until the very end.
- Hemera (Nirvana) mentions that a powerful Phantom Core can be obtained in the Demon Cave. Does she mean Fafnir, whom I had already beaten when I talked to Hemera, or is there another one (which I couldn't find despite scouring the whole Demon Cave once again)?
- There's a tombstone on the Seven Lords Island (previously encountered tombstones all contained optional boss monsters), but it seems the player doesn't get an opportunity to fight this one.
- A demon can be encountered in the Witches' Den (easternmost house, basement), but there's no way to interact with it.
- Even after having completed everything else, the player still isn't allowed to enter the mountains west of the Deep Woods.
- Some locations on the world map, especially the two fortresses near Shirakawa-go, can't be entered.
I would appreciate any information about whether I've missed something in this regard.
