This item is a type of treasure box available from the Mystery Boxes Merchant in Meridian.
It costs 1 Desert Glass, obtainable from humans.
This box is a potential alternative source of some ammo crafting resources.
Note that since this box can contain rocks, and the player can only hold 10 rocks at a time, this box allows the player to temporarily keep more rocks on-hand than normal.
This box contains one of the following chosen at random:
- 2 Rock Bundles (~42% chance; each bundle contains 5 rocks)
- 2 Metal Vessels (~29% chance)
- 2 Echo Shells (~17% chance)
- 2 Metalburn (~8% chance)
- 2 Metalburn + 8 Metal Vessels (~4% chance)
