There are many secretive places in the wild of God’s Domain. Most of these places housed Treasure Chests, waiting to be discovered by players. The items within Treasure Chests varied considerably, ranging from Copper Coins to Legendary Equipment.
Treasure Chests can be categorized into Common, Bronze, Mysterious-Iron, Secret-Silver, Fine-Gold, Dark-Gold, Epic, Inferior Legendary, and Legendary.  For most Treasure Chests, they can be directly opened, but for those chests of Epic-rank and above, they have their own requirements, such as for the Inferior Legendary where 3,000 players have to enter the chest and complete a trial.
There are other ranks of chests that are outside the scope of regular treasure chests, such as the Ancient Treasure Chest, Completely Random Treasure Chest, Magic Crystal Treasure Chest, and the Seven Luminaries Treasure Chest. 
When a Dark-Gold Treasure Chest is open, it illuminates a 400-yard radius and causes a commotion that affects a 3,000 or 4,000 yard radius.
