The Dangling Depth Dweller is a Spider variant found in the Ruins. They drop from the ceiling when the player steps on their web.
On the ground, they can leap at enemies in the same way as Spider Warriors. Their webs are commonly found in the Military and LabyrinthBiomes, along with Ornate Chests. Their nests are stuck on the ceiling and unreachable, although they can be destroyed by igniting anything flammable in the center of the web.
Below is the number of hits it takes with each weapon to kill Dangling Depth Dwellers when playing with characters with a default damage modifier. The Weather Pain is not included due to the random nature of its projectile.
In Don't Starve Together, their webs are permanent and cannot be destroyed by lighting nearby items on fire. Dangling Depth Dwellers will also spawn from the nearby dens when a player chops a webbed Mushtree.
A resource-friendly way to dispose of a nest involves lighting a single Log on fire directly underneath the nest. This can be done by dropping a Log at the center of the web. The center can be identified by the player character icon covering the body of the spider icon on the map. Destroying the spiders that drop down first will make this task easier, but if multiple nests are located close to each other, more than two spiders might drop at the same time. This tactic does not work in Don't Starve Together.
