How to Get to Adamantine Forge BG3 Complete Route Guide

The Adamantine Forge stands as one of the most rewarding and hidden secrets within the first act of Baldur's Gate 3. Finding this legendary crafting station allows adventurers to forge exceptionally powerful equipment that can easily carry a party deep into the middle stages of the game. Navigating the treacherous paths to its location requires thorough exploration and a clear understanding of the Underdark region.
Navigating the Depths of the Underdark
Before you can set foot near the legendary forge, your party must find a way into the subterranean world known as the Underdark. Multiple entry points exist throughout Act 1, including the defiled temple inside the Shattered Sanctum and the hidden elevator in the Zhentarim Hideout. Whichever path you choose, your immediate goal is to safely reach the Decrepit Village located along the central waterways.
The Decrepit Village is occupied by hostile duergar who protect the docks from unwanted intruders. Defeating these lookouts or successfully navigating their dialogue is essential to gaining control of their shoreline transport. Once the area is secure, your party can interact with the wooden skiff at the docks to begin the next leg of the journey.
Braving the Waters to Grymforge
Boarding the duergar boat triggers a short voyage across the dark, cavernous waters toward the Abandoned Refuge. During this transit, you may encounter another patrolling ship filled with rival cultists demanding to inspect your cargo. Overcoming this encounter through clever deception or direct combat will allow your vessel to safely dock at the grand port of Grymforge.
Grymforge serves as a massive ancient fortress occupied by True Soul Nere and his duergar mercenaries. Upon arriving, you should activate the local waypoint to ensure your party can easily return after resting. From the central docks, you must look for a path leading toward the upper scaffolding and broken iron walkways that overlook the excavation site.
Discovering the Hidden Path to the Forge
Reaching the actual forge requires navigating a series of high metal platforms connected by complex lever systems. Players can utilize individual character jumping abilities or movement spells like Misty Step to bypass the trickier gaps in the architecture. Moving carefully along these suspended paths will eventually bring your party to the Ancient Forge waypoint.
Just beyond this travel point lies a massive staircase descending into a lake of bubbling magma where the structure rests. This area is heavily guarded by environmental hazards and a massive automated construct that activates once the forging process begins. Preparing your team with bludgeoning weapons and fire-resistant items is highly recommended before stepping onto the central anvil platform.
