Original post (in Chinese) from: http://bbs.colg.cn/thread-4167917-1-2.html
Map and equipment information are based from www.tosbase.com (Thanks Tsuyucchi for Lv 143 map name!)
Note that chest level corresponds to key level (Lv1 chest does not require key), although these chests does not need Scout or Shovel to open. Key will be consumed ones you open the chest.
This is an uncompleted list, some chest locations are not included. Also these are not âhiddenâ chests which require you to be a Scout or purchase item from shop to locate. These chests can be opened by anyone, and everyone have their own chests.
Update: Just found Key drop on ToSbase.com, it will tell you which boss each key drops from: http://www.tosbase.com/database/items/?item_name=treasure+chest+key&search=
Update2: All items are now linked to tosbase, you can check their stats and such. Original item sample pics are removed.
