Wailing Woods is in the NE side of the map:
- Only the chests in the central area of Wailing Woods count. There are some chests on the outskirts of the woods, but those don't count for this challenge.
- Wailing Woods is very crowded during the first days of Week 2 because of everyone else trying to do the challenge. It may be a good idea to complete this challenge at a later time if you are having issues. You can even complete it in week 3 or week 4 when Wailing Woods will once again be deserted and you'll have all the chests to yourself. Weekly challenges DO NOT EXPIRE when the week ends!
