Overview of Wailing Woods you can see a small maze park and 4 big tree in each corner and small hut in the middle. In this place player rarely drop here because of there are less chest and they don't wanna get stuck in a battle of very close range. But if you like to play as a chill mode in the beginning of the game this place is very good for you, you can get well material out of it and also a very good items out of this area as well.
1. Each Corner of the maze
These chest are alway spawn there at the same exact corner of the area. And if there is no other player drop here you sure already get yourself 4 chest. Without Fighting.
