A large descending Cavern with Limestone
A very dark Cavern, near the bottom of the layer
The Cavern layer of The Betweenlands begins just below the surface, at a Y-layer of 100, and continues down until it reaches the Lake Cavern layer, at Y=45.
The caves can range from very small to tremendously large, and contain many ores and unique plants. There are sometimes small breaks on the surface which lead to these caverns, and occasionally giant ravines creating deep cuts in the earth that expose ores and other potential systems of caves. Occasionally large seams of limestone, often called Limestone Caverns, can be found. The fog is very dense down here, and an alternative ambient track plays, slowly fading in from the surface ambience starting from Y=110 downwards. There are also additional cave ambience noises that play occasionally.
The Cavern layer has a location title that appears briefly to players who enter it.
Composition[]
The Cavern layer consists of:
Betweenstone, extremely commonly- Swamp Dirt, in patches from Y=95 to Y=45
- Stalactite, in formations on the floor or ceiling
- Moss, in patches
- Lichen, in patches
- Cave Moss, in clusters hanging from the ceiling
- Thorns, in clusters hanging from the ceiling
- Limestone, in large, relatively uncommon seams from Y=95 to Y=45
- Sulfur Ore, in common veins from Y=100 to Y=45
- Slimy Bone Ore, in uncommon veins from Y=100 to Y=45
- Octine Ore, in relatively common veins from Y=70 to Y=45
- Syrmorite Ore, in uncommon veins from Y=100 to Y=85
- Pot of Chance, in very uncommon, large clustersSimulacrums, rarely in the various levels.
Mobs[]
Swamp Hags, Wights, Chiromaws, Infestations, Stalkers and Boulder Sprites can spawn down here, and rarely Harlequin Toads if the above biome supports them.
