The Spider Cavern is a dungeon in Spider Forest, found in Act III. Players need to explore the Cavern in order to obtain Khalim's Eye, which can be found in a gold chest guarded by the super unique monster Sszark the Burning.
As its name implies, the Spider Cavern is infested with both Poison Spinners and Flame Spiders. As the Cavern is very similar to the other spider-ridden dungeon found in the Spider Forest, the Arachnid Lair, many players find themselves searching the wrong dungeon for Khalim's Eye.
