Not to be confused with Buried Treasure, the Mysterious Midnights expansion.

A module designed to make underwater more interesting, this will allow fortune tools to dig up buried goodies from in the sand: some common, some rare, including blocks, messages-in-bottles, seaweed, and squid. There's a variety of items you can find! Only sand in deep water will uncover treasure.


Treasure drops can only be obtained by mining sand blocks when the following conditions are met:

  • The sand block is broken with a tool enchanted with Fortune I, Fortune II or Fortune III
  • There is a water source block at the player's feet, head and four blocks above the player's feet.

Practically this means treasure can only be found in sand if the player is in at least 5 blocks deep of water and submerged.

The chance of a sand block dropping treasure increases with the level of fortune on the tool used:

Enchantment Chance of a treasure drop
No Fortune Enchant 0%
Fortune 1 5%
Fortune 2 17%
Fortune 3 25%

Items Found[]

If a sand block is randomly chosen to become a treasure item, it may spawn a squid, a guardian or one of 12 items (one of those items is a message-in-a-bottle item; there are 20 possible messages to find).
