Ocean ruins are underwater structures primarily composed of stone bricks or sandstone. They are found in ocean biomes and rarely on beaches, and are inhabited by drowned and sometimes zombie nautiluses alongside them. They contain chests, suspicious sand, and suspicious gravel that contain a variety of loot, notably the buried treasure map and the sniffer egg. Ocean ruins have cold and warm underwater variants that vary from single huts to large villages.

Generation

[edit | edit source]

Cold ocean ruins generate in normal, cold, and frozen ocean biomes or in their deep variants. They are composed of stone materials and contain some suspicious gravel blocks that can be excavated using a brush.

Warm ocean ruins generate in warm, lukewarm, and deep lukewarm ocean biomes, and are composed of sandstone and stone materials as well as having some blocks of suspicious sand within them.

Ocean ruins may at times be at least partially buried, including with their airspaces. During generation, all air blocks and structure blocks act as structure voids. This means that their associated suspicious blocks are also located under layers of usual sand, gravel, and even stone.

Suspicious sand and gravel randomly replace sand and gravel respectively during generation, and are not part of the structure definition.

Although most ocean ruins generate underwater, they sometimes generate on land, bordering a beach or another seaside biome.

30% of ocean ruins generate as large ocean ruins; the other 70% generate as small ruins. If the ocean ruin is large, there is a 90% chance for 4-8 (inclusive) small ocean ruins to generate around it in a cluster. If the ocean ruin is warm, large ocean ruins generate with a structure integrity of 0.9 and small ocean ruins generate with a structure integrity of 0.8. If the ocean ruin is cold, the "brick" variant of the chosen structure type generates with a structure integrity of 0.9 if large and 0.8 if small. The "cracked" variant generates with a structure integrity of 0.7 and the "mossy" variant generates with a structure integrity of 0.5, both regardless of size. Reduced structure integrity may also remove drowned and zombie nautiluses from the structures.

Structure

[edit | edit source]
Main article: /Structure
This section is missing information about: Specific chance of zombie nautilus spawning
 
Please expand the section to include this information. Further details may exist on the talk page.

The shape and size of ocean ruins varies greatly, and they often generate together in groups to create ruined villages.

All but two of the structures contain a loot chest with loot inside. The chest contains loot for specifically either a small or large sized ocean ruin structure and may be buried under blocks such as gravel and sand.

Cold ocean ruins are primarily composed of stone bricks, gravel, and suspicious gravel, and they also contain prismarine, sand, magma blocks, sea lanterns, polished granite, glazed terracotta, bricks, planks, cobblestone, mossy cobblestone, stone brick stairs, obsidian, or a chest with loot in it. Warm ocean ruins are primarily composed of sand, sandstone, and suspicious sand, and they also contain polished granite, polished diorite, sea lanterns, magma blocks, gravel, terracotta, sandstone stairs, or a loot chest.

Natural ocean ruins generate following the rules above and may not exactly match the stored structures.

The structures below are located in the folder client.jar/data/minecraft/structures/underwater_ruin. The following is a complete table of the structures with their filenames, descriptions and what they consist of.

Upon world generation, many of the structures spawn with drowned (usually one or two, though a few structures have three or four). These drowned are persistent, and do not despawn. Adult drowned wielding tridents may also spawn riding a zombie nautilus as a zombie nautilus jockey.

Zombie nautiluses spawned from ruins are also persistent and will even spawn on Peaceful difficulty, despite being monsters, as the mobs spawned from ocean ruins count as part of the structure and ignore conventional spawning mechanics, leaving the zombie nautilus spawning on Peaceful by itself.[1]

  1. a b The size of stacks (or for unstackable items, number) of this item on any given roll.
  2. a b The weight of this item relative to other items in the pool.
  3. a b The odds of finding any of this item in a single chest.
  4. a b The number of items expected per chest, averaged over a large number of chests.
  5. a b The average number of chests the player should expect to search to find any of this item.
  6. a b 'Nothing' does not refer to the chance of an empty chest. Instead, it refers to the chance that the random loot generator does not add any loot on a single roll.
  7. a b c d All enchantments are equally probable, including treasure enchantments (except Soul Speed, Swift Sneak, and Wind Burst), and any level of the enchantment is equally probable.

In Java Edition, each underwater ruin small chest contains items drawn from 3 pools, with the following distribution:

  1. a b The size of stacks (or for unstackable items, number) of this item on any given roll.
  2. a b The weight of this item relative to other items in the pool.
  3. a b The odds of finding any of this item in a single chest.
  4. a b The number of items expected per chest, averaged over a large number of chests.
  5. a b The average number of chests the player should expect to search to find any of this item.
  6. a b 'Nothing' does not refer to the chance of an empty chest. Instead, it refers to the chance that the random loot generator does not add any loot on a single roll.
  7. a b All enchantments are equally probable, including treasure enchantments (except Soul Speed, Swift Sneak, and Wind Burst), and any level of the enchantment is equally probable.

An ocean ruin in Java Edition that also generated completely on land. The loot chest is not waterlogged and does not have a water block on top of it.
  • In Bedrock Edition, ocean ruins generate with approximately equal spacing in the X and Z directions.
  • In Bedrock Edition, the loot chest of ocean ruins generates with a water block above it.[2] This can be seen in the first image. In Java Edition, this is not the case, according to the second picture.[3]
