Lissith's Silk, which comes from the corpse of the named Giant Black Widow spider Lady Lissith, is one of the six keys needed to gain admission to battle Dread Horn, the Peerless of the Twisted Weald. The purple silk spawns randomly and comes with a countdown timer. Lissith's Silk will disappear when the timer expires.
When all 6 keys are collected, they each need to be dropped onto the statue that is located in a stone ruin in the southern area of the Weald. The statue sits on an altar that is surrounded by rocks and dilapidated walls. The keys are: Blighted Cotton, Gnaw's Fang, Irk's Brain, Lissith's Silk, Sabrix's Eye, and Thorny Briar.
- Irk's Brain is considered the most difficult of the keys to obtain.
