Edge island

samatron, since December, I've only been playing SoD! So, both Catherine's secondary skills – the initial ones (if you don't change them, they remain as they are), and the artillery in the hut (67, 51) are set by default – if not by you, then by whom? Check it out yourself! Now, about something sad. After the last battle with the turquoise faction, I saved the game (Merist attacked during the turn transition), but when I loaded this save and continued the game, after some time, it crashed with an application error for an unknown reason. I checked both in SoD and in the Complete Collection – the same thing happens. I'm afraid I won't be able to continue, although I could try replaying from the previous save. For now, I've put it aside.

The Dimension Door is disabled; it can only be obtained with the Grail (I will disable the building option in cities), I think in a way you are familiar with.

Besides installing it in the Conflux, perhaps it could be given to a Seer in exchange for that spell? Now I know for sure: it's on a scroll! But: 1. Enemies can take the scroll. 2. You are unlikely to stumble upon it by chance; you didn't provide any clues for a targeted search, and searching the entire map for it is tedious. Regarding the buried Grail, I'll add: it's bad that it's in the Underworld! As I'm starting to understand, the computer has a significant advantage over the human player when searching for the Grail: it only needs to reveal a small part of the puzzle map to dig up the Grail – a human usually needs to reveal all or almost all of the pieces, and even then, it's sometimes unclear where the place is. In my case, on this map, although many obelisks were definitely not visited by the computer players, the Blues dug up the Grail, and I only saw 2 pits in that place!
