The tomb's outer entrance
Tomb of Khan Dakab is a one-level dungeon that can be found in Dahlgur Oasis in Act II of Diablo III. Entering the dungeon will start the event Lost Treasure of Khan Dakab.
This dungeon is not guaranteed to appear, but if it does, a large sank ruins pit filled with Electric Eels and Deceivers will surround the entrance. To open the door, player must pull the two levers, one of each will spawn a rare Deceiver with minions.
The dungeon itself is a randomly generated labyrinth, the goal is to find the lever and open the door to the burial chamber (which is very close to the entrance). The tome, "The Last Will of Khan Dakab" is found in a satchel before the door, revealing that Khan Dakab, afraid of his riches bringing bad luck to his family, sealed the door so that no one ever recovers it.
