I added mist. Plasmified wormways do not count as an seperate area and haunted bellhart is a just a previous version of bellhart, so i do not count that.
I know, but I want the areas and subareas to be next to each other because it looks better and in this case exhaust organ can be accesible in act 1, but bilehaven and most of bilewater are not accesible, so I would have to split them.
