When your expedition comes to an end, roll the challenge dice and compare to your progress.
On a strong hit, you reach your destination or complete your survey. Mark a reward on your discoveries legacy track per expedition's rank: troublesome=1 tick; dangerous=2 ticks; formidable=1 box; extreme=2 boxes; epic=3 boxes. Any allies who shared this expedition also mark the reward.
On a weak hit, as above, but you face an unforeseen complication at the end of your expedition. Make the legacy reward one rank lower, and envision what you encounter.
On a miss, your destination is lost to you, or you come to understand the true nature or cost of the expedition. Envision what happens and choose one.
- Abandon the expedition: Envision the cost of this setback and Pay the Price.
- Return to the expedition: Roll both challenge dice, take the lowest value, and clear that number of progress boxes. Then, raise the expedition's rank by one (if not already epic).
