The Adamantine Forge
The Adamantine Forge is a Quest in Act One of Baldur's Gate 3 in Grymforge. It is initiated by learning of the forge of the same name by reading The Great Furnace of Grymforge,
Filro the Forgotten's journal, or speaking with Dhourn after freeing him of the Spectator's petrification or casting on his corpse.

Walkthrough
Discovering the forge
To learn about the Adamantine Forge, there are three drow wizards who each hold a unique piece of information about the forge. Each of them have met a terrible fate in the Underdark.
Dhourn
Dhourn is one of many petrified drow west of the Selûnite Outpost. An easy way to get to Dhourn is by entering the Outpost near the statue of Selûne and moving to the broken window X: 141 Y: -240. It is necessary to walk through it and climb down the knotted roots. If moving west past the droves of petrified drow, then a cutscene triggers where a Spectator appears and attacks the party. Upon its first turn, it unpetrifies the drow, typically starting with Dhourn. Dhourn and any other drow the Spectator resurrects are charmed and fight against the party until the Spectator is defeated. Then they will become neutral.
If keeping Dhourn alive, he'll talk to the party, otherwise his corpse can be spoken to with Memory Shard with information on the Adamantine Forge. Dhourn explains that he had two other rivals seeking the forge but, after realising how long he was petrified, he is the sole person left to claim the glory for discovering the Forge. After this, he and any unpetrified drow attack the party, as he sees them as possible rivals.
An Arcana check (DC 10) is needed to probe the thoughts within the shard. If successful, it shows images of the Adamantine Forge and hints to its location beyond an ancient stronghold.
Filro the Forgotten
Filro the Forgotten X: -50 Y: -163 has a camp south of the Sussur Tree Waypoint. He has gone mad during his time in the Underdark and becomes hostile when the party approaches him, alongside several Hook Horrors. Once he has been defeated, his Scribbled Notes can be looted from his corpse. If reading the notes, passing an automatic Investigation check (DC 15) reveals that the forge guardian is weak to magma and a 'hot hammer.'
Xargrim
Xargrim's corpse can be found beyond the Guardian GateX: 55 Y: -88 in Ebonlake Grotto. The gate is to the north of where Sovereign Spaw is located. In order to access Xargrim's corpse, it is neccessary to complete Defeat the Duergar Intruders. After that the myconid Sovereign will open the gate. It is also possible to open the gate by force, by attacking it; then the myconids of the grotto will become hostile.
Once inside, a book, Flumph Mating Rituals can be looted from Xargrim's corpse. Reading the book to discover its secrets gives the following options:
- [INVESTIGATION] Examine the book closely. (DC 15)
- [NATURE] Recall what you know of this title. (DC 15)
- [WIZARD] [NATURE] Recall what you know of this title. (DC 15
)
Succeeding any of the checks, the book reveals itself to be disguised. Its true name is The Great Furnace of Grymforge. The book contains exact instructions for how to operate the Adamantine Forge once it is located.
Reaching the forge
One way to access the Adamantine Forge is by completing Get Past the Rubble. Once the rubble is clear, the party must follow the pathway until an Iron Ladder X: -648 Y: 409 allows them to climb down. There is a metal platform that connects to a walkway - it is moveable through a set of levers. The levers can be used to descend another two sets of metal platforms, but this isn't necessary. Instead, the party can walk further south on the first walkway until they come across a broken statue. The statue remains can be jumped across to move to the second platform X: -624 Y: 344. It is necessary to send one party member over to the next platform using this method, then the party member must move south to find a set of two levers. Operating the levers to move the party members on the other side, then having the party members jump down to the new area, should instantly activate the Ancient Forge Waypoint. The whole party can now be teleported to the waypoint.
Another way to skip most of the journey to the Forge is using X: -607 Y: 314 to bypass the rubble entirely and activate the Ancient Forge Waypoint to move the rest of the party up to the Forge.
, or (requires sufficient strength) with one party member, near the platform east of the cave-inForging an item
In order to forge an item, the party needs mithral ore and a mould.
Finding the moulds
The moulds can be located around the Forge area:
Longsword Mould - On the metal scaffolding X: -625 Y: 404
Mace Mould - On the table south of the Ancient Forge Waypoint X: 613 Y: 284
Scale Mail Mould - On the ground southwest of the Ancient Forge Waypoint X: -616 Y: 264
Scimitar Mould - Looted from a skeleton near some levers X: -604 Y: 323
Shield Mould - Looted from a skeleton behind a locked door (DC 12) at the top of the stairs X: -558 Y: 409
Splint Mould - East of the Ancient Forge Waypoint near a skeleton X: -594 Y: 310
Finding the mithral
There are two Mithral Veins:
- Southwest of the Ancient Forge Waypoint. It causes several Animated Armours to become hostile. After defeating them, move to the rocks southwest and follow the path to a lava-filled area. Jump across the rocks to find the vein X: -645 Y: 255.
- On the steps leading down to the Forge, follow the rocks east. A group of Magma Mephits ambushes the party X: -556 Y: 277.
Only one ore is needed to resolve the quest. Attack the vein with force damage (i.e. spells like Mithral Ore.
Combining the materials
- Place the mithral ore into the Crucible at the centre of the Forge
- Place the desired mould in the Mould Chamber
- Use the Forge Lever on the southern side of the platform to lower it down to the lava
- Once the platform is lowered, use the Lava Valve to fill the area with lava
- Use the Forge Lever to cause the Forge's hammer to hit the mould, shaping the item
- Pick up the completed item at the mould chamber
The first time the Lava Valve is used, Grym appears to defend the Forge. Defeat it while continuously adding lava, as Grym cannot be damaged unless it has the superheated condition. This condition replaces several of Grym's damage immunities:
![Resistant to all Slashing Resistant to all Slashing](/w/images/thumb/b/b0/Slashing_Resistance_Full.png/28px-Slashing_Resistance_Full.png)
![Resistant to all Piercing Resistant to all Piercing](/w/images/thumb/1/1c/Piercing_Resistance_Full.png/28px-Piercing_Resistance_Full.png)
![Vulnerable to Bludgeoning Vulnerable to Bludgeoning](/w/images/thumb/1/11/Bludgeoning_Vulnerability.png/28px-Bludgeoning_Vulnerability.png)
![Resistant to all Acid Resistant to all Acid](/w/images/thumb/f/f5/Acid_Resistance_Full.png/28px-Acid_Resistance_Full.png)
![Resistant to all Thunder Resistant to all Thunder](/w/images/thumb/4/4c/Thunder_Resistance_Full.png/28px-Thunder_Resistance_Full.png)
![Resistant to all Cold Resistant to all Cold](/w/images/thumb/4/49/Cold_Resistance_Full.png/28px-Cold_Resistance_Full.png)
![Resistant to all Force Resistant to all Force](/w/images/thumb/c/c3/Force_Resistance_Full.png/28px-Force_Resistance_Full.png)
It remains immune to all other damage types.
The "hot hammer" mentioned by Filro is the Forge's hammer - draw Grym to the centre of the platform and use the Forge Lever to hit it with a huge amount of bludgeoning damage. The first time this is done, several hostile Magma Mephits will spawn. Using the hammer while Grym is not Superheated will not deal damage, but will knock it prone.
To make a different item, use the Mould Ejection Lever to replace the mould. Repeat the steps to make a new item.
Quest rewards
The quest rewards experience several times while progressing the quest:
- Reaching the forge: 30 xp
- Completing the quest: 120 xp
By successfully acquiring all mithral ores and using the furnace twice, two of the following items can be created. It is possible to forge two of the same item, but no more than two items in total — because there are only two Mithral Ore in the game:
Adamantine Longsword
Adamantine Mace
Adamantine Scale Mail
Adamantine Scimitar
Adamantine Shield
Adamantine Splint Armour
