The Infernal Cave is a small dungeon accessed from the Pit, an optional area in Act I (only on Hell difficulty).

At the bottom of the room is the Infernal Machine, an uberboss that spawns elite monsters. Upon his destruction, it drops the charm Optical Detector.

Except the boss and the golden chest on the right side of the room, there's nothing else.


Unlike other elites monsters, those who are spawned in this cave drop poor loot to prevent afk farming.
