The Depths

The Depths is a biome located under the Left Ocean, which consists of a series of cave systems which eventually open up into the Aquatic Ruins, a mini-biome.

The Depths consists of 3 layers, which have different types of terrain, which have chest shrines floating around in the waters.

The Depths is very dangerous, so the player may want to be prepared before entering.

Layer 1
Layer 1 consists of small and cramped cave systems, with few chest shrines. This layer acts as a kind of maze, making getting to Layer 2 difficult. This layer should be explored after defeating the Eater of Worlds or/and the Brain of Cthulhu.

Layer 2
Layer 2 consists of more open caves, with much more chest shrines and much more loot. The enemies are much more hazardous, and some usually Hardmode-exclusive enemies will begin popping up here, making this layer much more dangerous.
