A huge Lake Cavern with Underground Ruins
A lake formed as part of the Caverns, with swimming Anglers
The Lake Cavern layer of the Betweenlands begins just below the normal Cavern layer, at a Y-layer of 45, and continues down until it touches Bedrock, at Y=0.
Caves and ravines continue to generate down here, but they are completely flooded from Y=15 downwards, forming underground lakes. The same underground ambient tracks play here as in the normal Cavern layer, and there is less fog.
Composition[]
The Lake Cavern layer consists of:
Pitstone, extremely commonly- Cave Grass, commonly
- Moss, in patches
- Lichen, in patches
- Cave Moss, in clusters hanging from the ceiling
- Thorns, in clusters hanging from the ceiling
- Scabyst Ore, in uncommon veins from Y=45 to Y=0
- Valonite Ore, in rare veins from Y=45 to Y=0
- Life Crystal Stalactite, in underwater formations from Y=15 to Y=0
- Pot of Chance, in very uncommon, large clusters
- Swamp Water, in lakes from Y=15 to Y=0
- Stagnant Water, in uncommon pools
Mobs[]
Swamp Hags, Wights, Infestations, Stalkers, and Chiromaws can spawn down here, Anglers, Cave Fish and Cave Jellyfish in the water, and rarely Harlequin Toads if the above biome supports them.
Structures[]
Underground Ruins and Underground Oases can generate somewhat uncommonly down here, and Tar Pool Dungeons more rarely.
Loot[]
Pots uncommonly spawn in these caves as treasure, using cave_pot as their loot table.
