Cavern



The Cavern layer is the largest layer, beginning just below the Underground and extending all the way down until the Underworld layer. It is characterized by darker stone background tiles. Stone is the predominant block in this layer (as opposed to Dirt in the Underground). Caverns contain occasional Underground Cabins where valuables can be found, as well as Mushroom Biomes, dangerous traps, rare and dangerous Spider Nest mini-biomes, and much more. Lava begins to appear around -2100ft in small pools, which gradually become lava wells at around the -3000ft mark.
