It's 30 that makes it rise. Technically, a garrison and > 29
troops, but there are only whole fief troops, i.e. 30.
Shadow Institute is a key building. It has several functions to help manage obedience and morale.
Aah, thanks for the correction.
I have all buildings in every fief, but have never used the Shadow Institute through necessity, other than for the quest to prove your worth to a captured monarch, or to satisfy curiosity when it was 1st introduced.
I guess I'm lucky to have been playing this since it 1st arrived on this site a few years back, so I have been kinda forced to be patient & that has led me to spend a few in-game days\weeks allowing Obedience to build up, as well as Gold, so have fortunately not had any problems with maintaining either.
But I can certainly see how someone who's newer to the game might, particularly if they rush to take the next fiefdom & reach the next lewd content, too quickly.
