Diablo 3 Act I Random Dungeons Guide

Random Dungeons spawn in set locations. They do not always spawn, but when they do, they appear in a specific zone. Some of these locations are needed for the "No Stone Unturned" achievement. We have also included the creatures that spawn there, for "The Takedown" and "Keep it Rare" achievements. This guide will tell you the locations and description of all the Random Dungeons in Diablo III.

The Lore Books that can be found in each dungeon are also listed, for the achievements: A Quick Study, Taking Notes, Historian of Tristram.

If you are looking for a specific dungeon and it is not in the area, leave the game and come back to reset the zone, then search for the dungeon again.
