I already understand that with a couple of subfolders for most castles, some need a larger number.
Necromancy - minimum 3 (two with expert necromancy, one warrior with expert tactics)?
Demonology - 3 (an additional subfolder for optimizing demonology)?
Should the number of subfolders be approximately twice as small as the main folder?
Need the opinion of experts.
