Spider Nest

Spider Nests are rare mini-biomes that can be located underground, noted by the black background wall and the numerous webs filling the area. The Cobwebs filling this area rapidly grow back, which is a unique feature of the biome. Spider Nests are the only location where one can find Web Covered Chests and all unique treasures discovered therein. It is also the only place the bound Stylist will spawn.

Trivia

 * One of the background pieces appears to be someone bound in web. This could be a reference to the actual Lost Girl.
