It has finally arrived! The Mojang team has been working tirelessly to bring players the biggest changes to world generation since Minecraft first released in 2011. In Caves & Cliffs Part 2, the Overworld gets new terrain generation, an increased world height, dripstone caves, lush caves, and so much more!
The update is available for Bedrock Edition on Xbox Series X, Xbox Series S, Xbox One, PlayStation 5, PlayStation 4, Nintendo Switch, iOS, Android, and Windows 10 and 11. It’s also available for Java Edition on Windows, macOS, and Linux.
Opening up a 1.18 world feels like it's brought new life to the Minecraft universe. Not only are mountains taller and caves deeper, but even old biomes look fresh and new with more realistic terrain. In fact, there’s so much added and changed in this update that we’re jumping right into a guide on everything added or changed in Minecraft’s 1.18 Caves & Cliffs: Part 2 update!
Updating old worlds to 1.18 will be basically seamless! With the mechanic Mojang calls “blending”, surface height, biomes, terrain, and caves will all blend together. In old chunks, if there is any bedrock at y=0, the sections below non-air blocks will be filled with new generation. The old bedrock between y=0 and y=4 in old chunks will be replaced with deepslate and a new bedrock layer is formed at y=-64.
We’d be remiss to not remind everyone that the Deep Dark biome has been delayed until 2022 to be released with the 1.19, the Wild, update. So we’ll all have to wait a little longer to be terrified of the Warden mob.
The Deep Dark biome will also be home to the sculk blocks and include loot chests and mysterious structures.
While there are little additions of blocks from 1.17 to 1.18, there are a few changes and additions to Minecraft:
Added a new music disc from Lena Raine titled ‘Otherside’. This can be found rarely in Stronghold Corridor Chests, or much more rarely in Dungeon Chests.
Enchanting Tables now emit a low amount of light
Using Shears on the tip of a Cave Vine, Twisting Vine, Weeping Wine, and Kelp will stop them from further growing
Copper Ore now drops 2-5 (formerly 2-3) Raw Copper items
In the Stonecutter, a Block of Copper can be converted to 4 Cut Copper
Restricted Big Dripleaf placement to Clay, Grass, Dirt, Farmland, Moss, Rooted Dirt, Podzol, and Mycelium
Ore Veins are large, rare, snake-like underground ore formations. Copper Ore Veins form between height 0 and 50 and are mixed with Granite, while Iron Ore Veins form below height -60 and -8 and are mixed with Tuff.
While we already covered all the biome changes in another guide, we’ll still cover the exciting parts here. You can always read our other guide for deeper information and more changes (such as biome name changes). However, here are the new mountain biomes added!
The meadow is a grassy biome filled with patches of flowers and turquoise-green grass or double tall grass. Rarely, a lone oak or birch tree of any size can generate and always has a bee nest. Both pillager outposts, and plains villages can generate in this biome, making this the only mountain biome where villages can generate. The meadow biome generates in the lower sides of some mountains but can also generate standalone in plateaus, mainly next to plains and other temperate biomes.
The grove creates a forest of spruce trees on the sides of a mountain. The surface is covered with snow, snow blocks, dirt, and a lot of powder snow instead of grass blocks. This biome generates in high altitudes beneath the peaks and on hilltops next to forested biomes such as dark forests and taigas, and can generate at lower altitudes if next to snowy biomes.
The snowy slopes is a mostly barren biome covered in snow, multiple layers of snow blocks and powder snow, with some sides also having stone cliffs. This is the only mountain biome where igloos can generate. Just like the grove, this biome generates at the slopes of the mountain, beneath the peaks and in hilltops. They’re generally near areas with less forested biomes, like plains and snowy tundras, and can start generating at lower altitudes in snowy regions.
The jagged peaks are one of the three peak biomes that generate only on the top of the mountain if they are tall enough, peaking at y=256. It is covered by a single layer of snow blocks with stone underneath often exposing ores such as coal, iron and emerald, and just like the snowy slopes, stone cliffs can generate in some sides of the mountain.
The frozen peaks are covered with snow, snow blocks, glaciers of packed ice, and occasional small blobs of ice. Frozen peaks generate in smaller and smoother hills near snowy, cold and temperate biomes, but it can also generate in slightly jagged and taller peaks.
The stony peaks biome is a warmer variation of both the jagged peaks and the frozen peaks biomes that generates when a mountain peak is in a region with lukewarm biomes such as savannas, and jungles. It doesn't generate snowy slopes or groves in the slopes of the mountain, unless there's a colder biome bordering the peak. It is mainly covered by stone, with large strips of calcite and exposed ores. The grass and foliage in this biome have a unique vibrant light green tint.
Noise caves are the new cave generation method. The name isn’t because due to sound, it’s more of a technical term. While cave carvers (aka openings) and canyons generate the same, they’re combined with the three new types of caves:
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.
Caves can contain aquifers, bodies of water with different heights, that are independent of the sea level. Aquifers can sometimes result in large underground lakes, form inside mountains, or on the surface. There’s even a chance they’ll generate as lava aquifers below y=0!
There are also two new biomes included with cave generation!
Dripstone caves generate with dripstone blocks and pointed dripstone both hanging as stalactites and growing from the ground as stalagmites. Small water wells of 1 × 1 blocks are generated in the ground. This biome also generates larger copper ore blobs compared to other biomes.
Lush caves generate underground at any height, usually in areas with forested biomes. Azalea trees generate on any empty space above a lush cave, with roots consisting of rooted dirt and hanging roots that generate down until reaching the lush cave.
Within, moss and ores covers the floors and ceilings, along with moss carpets, grass, and azalea bushes. On the ceiling, vines and cave vines with glow berries grow down and light up the caves. Spore blossoms grow from the ceiling and drip water particles. A lush cave contains springs and shallow lakes with clay where dripleaf plants grow out of them.
