Ministers
From Crusaderkings
You have five minister positions:
The first four characters are tied to a specific statistic, and will add their score in that ability to your ruler's. Example: Duke Gustav has a Diplomacy score of 7. His Chancellor has a Diplomacy score of 12. Duke Gustav's effective diplomacy score is 19, and would be reported on his character screen as Diplomacy 7 (19).
Of the five ministers, the Marshal and Diocese Bishop must be male, while the Chancellor, Steward, and Spy Master can be either male or female.
