Minecraft:Ocean Ruins

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

Generation

Cold ocean ruins generate in normal, cold, and frozen Minecraft:ocean biomes or in their deep variants. They are composed of stone materials and contain some Minecraft:suspicious gravel blocks that can be excavated using a Minecraft: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 Minecraft: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 Minecraft:structure voids. This means that their associated suspicious blocks are also located under layers of usual Minecraft:sand, Minecraft:gravel, and even Minecraft:stone.

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

Although most ocean ruins generate underwater, they sometimes generate on land, bordering a Minecraft:beach or another seaside Minecraft: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 Minecraft: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 Minecraft:drowned and Minecraft:zombie nautiluses from the structures.

Structure

Template:Main Template:Info needed section 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 Minecraft: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 Minecraft:gravel and Minecraft:sand.

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

Each Template:BlockLink indicates either a chest with random loot or the spawn location of a drowned/zombie nautilus Minecraft:mob.

Mobs

Minecraft:Drowned	Minecraft:Zombie Nautilus

Upon world generation, many of the structures spawn with Minecraft: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 also spawn riding a Minecraft:zombie nautilus as a zombie nautilus jockey.

Zombie nautiluses spawned from ruins are also persistent and will even spawn on Minecraft:Peaceful difficulty, despite being Minecraft: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.<ref>Template:Bug</ref>
