The Molten Vault Map Details

Forged in Gold

The Molten Vault is an area that can be accessed from The Drowned City. You'll be led to this place if you're doing the Treasures of Utzaal side quest.

This area is set up like a wide grid, with flowing lava passing through the area. The grid is separated by thick walls, with every room filled with machinery and enemies such as Gold-Melted Sentinels, Vaal Embalmed Rogues, and Gold-Melted Shamblers.

Be careful when exploring the area; the halls and rooms can get cramped, and the enemies can quickly corner and overwhelm you. Upon encountering The Aureaduct, you must defeat Mektul, the Forgemaster to progress in the quest Treasures of Utzaal.
