Arachnid Lair is an underground area in Act 3. It is accessed through Spider Forest.
Arachnid Lair belongs to the terror zone Spider Forest, Arachnid Lair and Spider Cavern. When it is terrorized in Hell, its monsters are 2 levels above your character, up to level 96, and give 25% more experience.
Arachnid Lair has one sparkly chest. A sparkly chest 
does a regular chest drop with a small chance to try to make every item unique, set or rare; otherwise it rerolls until it has one to three magic items.
