Stalagmite Biomes are an environment that can only be found inside Caves. They have been named after the abundance of Stalagmites that can be found in these areas. Turfs like Cave Rock Turf and Guano Turf are also abundant and cover most of the area. There are no known Plants that can be found in these biomes.
There are two types of Stalagmite Biomes, each having different features, both rarely spawning Nightmare Fissures.
The first type is abundant with normal Stalagmites. However, being their natural habitat, these areas are also heavily infested with Cave Spiders and Spitters which live in Spilagmites. There may be branches of this biome which are not infested, depending on World Generation.
Thulecite Sinkholes are usually found in here.
