Same thing with the Loot, which would mean that when the Monsters vanish with Xykon's death, you deal out Loot into the dungeon until the current deck runs out, then you're done. This one will need further behind-the-scenes consultation, though.
You do, however, deal Loot from the bottom of the dungeon up when it collapses, to prevent people from hanging around the Entrance to grab free Loot while someone kills Xykon, then grabbing the bonus for being the first to exit, too.
