Halls of the Blind

Halls of the Blind is an optional quest in the catacombs on dungeon level seven in the original Diablo. It involves entering a room full of enemies that can turn invisible. It is initiated by reading the Book of the Blind, found on level seven.

After reading the poem, the hero is able to enter a previously sealed room shaped like a figure eight and containing two smaller rooms. The room is filled with Illusion Weavers, which can turn invisible while moving about. They only become visible to attack. The quest is completed by retrieving the Optic Amulet, which is located inside one of the two smaller rooms.

Trivia

 * This quest returns in Diablo III's event, The Darkening of Tristram, as a minor event while exploring the Labyrinth. It functions similarly to the original quest: a long series of very narrow corridors with Light Radius set to zero, filled with hordes of the Hidden. In the end, a Resplendent Chest is found, containing Magic-quality Optic Amulet.
