The end of the Burnt Offering the reward is a specific card: Sihedron Medallion. Of which there is only one in the set. So the end reward is one character gets one reward and everyone else gets nothing.
Side Note: Is that the only Loot card in the entire box set?
Also the theory of the Adventure Deck boxes fitting in the main box is pretty cool; but with no center divide in the deck boxes, cards are just shifting around ramming into each other and getting damaged.
