The Catacombs

The Catacombs are a biome that can spawn during world creation, replacing the Crimson, Corruption, or Infestation. Despite being peaceful above ground, the maze-like chasms filled with traps can easily startle new players, along with a few Shattered Spirits and Bone Alters. The biome itself is themed around skeletons, bones, and death.

Most items, armors, and weapons here are based around movement, instead of DPS (Like the Corruption) and Tanking (Like the Crimson), and the lowest defence among them.

Monsters in this biome are typically faster than usual, and have less knockback and damage
