Pay close attention to the following:
- any domain that participate HAS to spend one diplomacy action
- any regent that took a very personal interest in the S&C/was very active, MUST pick a supportive adventure (I think most of you figured out this already)
Example: SM; was quite involved, got engaged in a duel, got grievously injured and needed time to recover, AND is getting married. That ISN'T covered by a diplo action!!! So it requires a supportive adventure action.
