1.18.0, the first release of Caves & Cliffs: Part II, is a major update to Bedrock Edition released on November 30, 2021.[1] It was first announced alongside the release of the Java Edition 1.17 snapshot 21w15a when Mojang Studios stated the Caves & Cliffs update would be split in two.[2] Features from 1.18.0 were being developed alongside 1.17.0 through Experimental Gameplay. This is the third major update for Bedrock Edition that is split into several updates since Village & Pillage in 2019.



Music Disc
  • Added a new music disc from Lena Raine titled "otherside".
    • Can be found on rare occasions in stronghold corridor chests, or much more rarely in dungeon chests.
    • Has a blue and green color to the ring area of the disc.

World generation[]

  • Completely overhauled.
  • Now stretch down to Y=-64.
  • The caves now generate in 2 layers of different stone bases depending on the depth.
    • The layer above Y=0 is made up of regular stone.
    • Stone transitions to deepslate from Y=0 to Y=-7.
    • Deepslate completely replaces stone from Y=-8 to bedrock.
  • Biomes such as the dripstone caves and lush caves now generate in the underground.
  • Contain aquifers, bodies of water with different heights, independent of sea level (Y=63).
    • Aquifers below Y=0 sometimes generate with lava instead of water.
  • Improved old caves to blend in with the new generations of caves better
  • New noise caves, coming in 3 forms, "cheese", "spaghetti", and "noodle".
    • Cheese caves have large stone towers stretching from the bottom of the cave to the top, and are often large enough to allow safe elytra flight.
    • Spaghetti caves are long, thin caves that have small aquifers and are more similar to original caves.
    • Noodle caves are thinner, squigglier, and more claustrophobic variants of spaghetti caves.
  • Comes in 6 sub-biomes:
    • Meadow
    • Grove
    • Snowy Slopes
      • Generates in the slopes of a mountain when next to plains and snowy tundra.
      • Covered in top snow, snow block and powder snow.
      • Only rabbits and goats spawn in this biome.
      • Igloos and pillager outposts can generate in this biome.
    • Jagged Peaks
      • One of three biomes that generate in the mountain peaks.
      • Covered in snow, snow blocks and stone.
      • Tends to generate in sharp and jagged peaks in areas with snowy, cold, and temperate biomes.
      • Only goats spawn in this biome.
      • Pillager outposts can generate in this biome.
    • Frozen Peaks
      • One of three biomes that generate in the mountain peaks.
      • Covered in snow, snow blocks, ice, and packed ice.
      • Tends to generate in smoother and less jagged peaks in areas with snowy, cold, and temperate biomes.
      • Only goats spawn in this biome.
      • Pillager outposts can generate in this biome.
    • Stony Peaks
      • One of three biomes that generate in the mountain peaks.
      • Covered in stone, gravel, and strips of calcite.
      • Tends to generate in any peak surrounded by warm biomes such as jungles and savannas, to avoid temperature clashes.
      • No animals spawn in this biome.
      • Pillager outposts can generate in this biome.
Ore veins
Upgrading of old worlds
  • Terrain from new chunks now blend with existing terrain from old chunks. Any player-made structures in these chunks are either intact, buried, or deteriorated.
  • The old bedrock layer between Y=0 and Y=4 in old chunks gets replaced with deepslate.
  • If there is bedrock at Y=0, lower places in old chunks are filled with deepslate and caves.
  • A new bedrock layer is placed at Y=-64.

  • Now can spawn in aquifers inside dripstone caves.
Glow Squids
  • Now spawn only in water blocks under Y=30.
  • Hostile mobs spawn only in areas where the light level is equal to 0.
    • This change affects only block-light and not sky-light.[3]

World generation[]

Amethyst Geodes
  • Now generate up to Y=30.
  • Now can generate in mountain peaks.
  • Red sand generates a bit higher.
  • Beaches are generally wider.
    • In some places there is a chance where no beaches generate at all, to provide some variation.
  • Because the terrain height is no longer controlled by biomes, the following sub-biomes no longer generate naturally and become unused in the game:
  • As a result of this change:
    • All deserts are now eligible for village and desert pyramid generation.
    • All taigas are now eligible for village and outpost generation.
    • All swamps are now eligible for swamp hut generation.
    • All snowy taigas are now eligible for igloo generation.
    • Worlds made in previous versions that generated these biomes will be converted into their default variants.
Dripstone Caves
  • Now generate naturally underground and inside hills or mountains.
  • Drowned can spawn in aquifers inside dripstone caves.
  • Increased the amount of dungeons, especially below Y=0.
  • Water lakes were removed, because aquifers could provide local water levels.
Lush Caves
  • Now generate naturally underground and inside hills or mountains.
  • Mineshaft pieces no longer generate if they were fully floating in the air.
  • Corridors now generate with wooden logs as pillars for support, or chains and oak fences as hanging support if needed.
  • Cobwebs no longer generate floating without an adjacent block.
  • Now generate higher up in badlands.

Ore distribution changes.

Ore distribution
  • Changed ore generation of all ores making them have a spread value like lapis lazuli ore. Some still retain a linear generation alongside a spread generation.
    • Coal ore attempts to generate twice: once, evenly between an altitude of Y=136 and Y=256; and as a spread, peaking at an altitude of Y=96 and generating between an altitude of Y=0 and Y=192.
    • Copper ore generates between Y=-16 and Y=112, generating the most at Y=48 and like all other ores, uses spread. It peaks at Y=48. Bigger blobs of copper ore generate in dripstone caves.
    • Iron ore attempts to generate three times: once as a spread peaking at an altitude of Y=256, generating above Y=80; another as a spread peaking at Y=16 and generating with a minimum height of Y=-24 and a maximum height of Y=57, and a smaller one spreading evenly between the altitudes of Y=-64 and Y=-32.
    • Gold ore generates between the altitudes of Y=-64 and Y=32, peaking at Y=-16. Also, extra gold generates below Y=-48. The extra gold that generates in the badlands biome was increased, with a top height limit from Y=79 to Y=256, and increased number of blobs.
    • Lapis lazuli ore attempts to generate twice: once, as a spread between the altitudes of Y=32 and Y=-32, peaking at an altitude of 0; and evenly between the altitudes of Y=64 and Y=-64, generating buried like ancient debris.
    • Redstone ore attempts to generate twice: once, evenly between an altitude of Y=15 and Y=-64; and as a spread, peaking at an altitude of -64 and generating below an altitude of Y=-32.
    • Diamond ore now generate as a spread, generating below Y=16 and peaking at altitudes near Y=-64.
    • Emerald ore generates above Y=-16 as a spread, peaking at Y=256 and decreasing in quantity as the altitude decreases.
Pillager outposts
  • Now generate in all the new mountain biomes.
  • Lava springs can now generate amid calcite, dirt, snow, powder snow and packed ice.
    • These changes allow lava springs to generate in mountains and snowy terrain.
  • Water springs don't generate higher than Y=192, and are less common.
Stony Shore
  • Now generate with strips of gravel.
  • Can generate alongside any biome instead of just extreme hills.
  • Now try to generate fully encased in stone, or deepslate at low y-levels.
  • The overworld now uses the multi-noise biome source type.
  • Terrain generation is now independent from biomes, with biomes adapting to whatever terrain they happen to generate throughout.[4]
    • This allows for natural variation in the terrain of any individual biome, both in terms of shape and elevation.
      • For example, forests and deserts could form up on a hill without needing a special biome just for that purpose.
    • This additionally allows for smoother transitions between biomes.
  • Terrain is now smoother and more extreme.
  • New random number generator is used for overworld generation.


  • Changed raid boss bar colour from pink to red.
  • Raid mobs now despawn after a raid ends if the players move too far away
Status effects
  • Hero of the Village effect now applies to all players who helped kill a raider once a raid is defeated, and the effect remains on the players, even if they travel outside the village.


Android External Storage
  • Players with external storage will be migrated to the new location at startup, due to storage changes required by Google.
    • Players can still play if the migration fails by closing the results window.
  • Raised cloud level from 128 to 192.
Height limit
  • Has been increased to 384 blocks, expanding 64 blocks up and 64 blocks down, with 319 being the limit upward and -64 being the limit downward.
Menu screen
  • Main menu background is changed to reflect Caves & Cliffs: Part II update.
World creation screen
  • Removed the Old world types.
    • Existing world with old world types are still playable, but do not get updated with 1.18 features.
