When setting up the scenario, are the blank tiles adjoining the rooms treated as doors that need to be opened to be revealed? Or is the entire level open from the start that you populate the entire dungeon during setup?
My group attempted with an almost full reveal in Scenario 93, but there are not enough standees to populate this dungeon.
I don't remember where I read it, but the fog tiles work like doors. One side it fog, the other is open passage.
