The Reapers will teleport themselves to the Hall of Judgment after a short dialogue when you reach them. The area around each Reaper will be free of enemies, giving you as much time as you need to rest before moving on to the next area. The most efficient order in which to contact the Reapers is in a mostly counterclockwise fashion: Reapers 4–6 could be visited in either order (4-5-6 or 6-5-4) without losing efficiency. Overall, the quest takes around 20–30 minutes to complete.
