Coming prepared to mission briefings gives you extra time to ask questions and research a topic relevant to your next adventure. You are trained in Mission Lore, a special Lore skill that can be used only to
Recall Knowledge, but on any topic related to an assignment, mission, or quest performed on behalf of another individual or organization. If you fail a check to Recall Knowledge with Mission Lore, you get the effects of the
Dubious Knowledge skill feat unless the question was already answered during a mission briefing. If you have legendary proficiency in
Society, you gain expert proficiency in Mission Lore, but you can't increase your proficiency rank in Mission Lore by any other means.
