I sat down in the throne room and looked at the stats of the Dungeon through the Dungeon Menu.
I can safely say that I can ignore Strength, Mystic, and Movement for now. Those sound more like stats you improve at the mid-game rather than the start, or stats you take advantage of if they're greater than the rest due to the start bonus... which I didn't get! In any case, I have no reason to improve them until I get outta the "beginner phase", which is making this Dungeon start to turn even by a little.
Knowledge is also postponed for later. I've already got tons of stuff to figure out, so getting a list of more stuff this place is capable of, which I may even not be able to do because of the Dungeon's low stats, ain't worth it in the beginning.
What I can focus on now at the start is the three creation-related stats: Facility, Subordinates, and Treasure.
