Spider Nest



Spider Caves, also known as Spider Caverns, are mini-biomes located in the Cavern layer. They feature distinct black Background walls and there are numerous Cobwebs filling the area. The Cobwebs rapidly grow back, which is a unique feature of the biome. Spider Caves can rarely contain Web Covered Chests, which they may generate with during world creation. The webbed Stylist NPC can spawn here.

Tips

 * The Dangersense Potion can be useful in locating Spider Caves, because the Cobwebs inside sparkle in a unique pattern.
 * Creating three-block-high diagonal tunnels into a Spider Cave using a hammer to slope the floor and ceiling will prohibit spiders from exiting (or entering, if they spawn outside), but not the player. This can be a good tactic to trap and easily kill spiders. Similarly, spiders can not fit into two-block-wide vertical tunnels and can be used the same way.
 * If one finds themselves crossing through a spider cave while creating a hellevator, in order to prevent cobwebs from generating and slowing the player down during freefall, it can be advised to place ropes or torches on the spider background walls, thus occupying the space where cobwebs are unable to grow. Alternatively, if one does not want to use up torches, they may use a hammer to remove the walls instead.
 * One can use the Spider Caves to farm money, as the quickly regrowing cobwebs can be broken and turned into Web Rope and sold for a decent amount of cash.

Trivia

 * The biome features unique background objects, such as a human corpse covered in webs.
