With the exception of Larissa Neathal, all Lords of Waterdeep give a bonus for completed quests if they are of a certain type. These points are scored at the end of the game - in part because your Lord is hidden.
There's also several Plot Quests that reward you with a bonus for completing certain types of quests. For instance:
Quell Mercenary Uprising
Reward: 8 VP
Whenever you complete a Warfare quest, you score 2 VP
Is this bonus added at the end, also applying to each Warfare quest you've completed before? Or is this quest popped up open next to your tavern to provide the bonus for every Warfare quest completed from then on? And, if the second interpretation is the right one, would this quest qualify for its own bonus?
