Baldur's Gate 3: How to reach and use the Adamantine Forge
A truly unique experience in BG3.
The Adamantine Forge is one of the most intriguing locations in all of Baldur’s Gate 3. It is an ancient forge that is used to create extremely powerful and unique weapons and armor.
However, the forge is both difficult to find and use, as you will need to follow a series of specific steps before you can even turn it on. There is also a terrifying enemy to face before you get to claim your new gear. In this guide, I will go over exactly how you can reach and then activate the Adamantine Forge in BG3.
To reach the Adamantine Forge, you have to go through the Underdark, which is the under-the-surface world in Baldur’s Gate 3. There are four different ways of reaching the Underdark:

Regardless of how you get there, you need to reach a specific waypoint called the Underdark – Beach. This waypoint is right in the middle of the Underdark, and you can find it southwest of the Myconid Colony and north of the Arcane Tower. There is a map screenshot below for reference.
Once you reach the beach waypoint, you need to take the boat that is located at the dock. This boat brings you to the Grymforge, a place where gnomes are enslaved, and has access to Moonrise Towers. You’ll next want to follow the steps below to get to the Adamantine Forge:
Only one of your characters needs to get up to that spot, as going forward will eventually allow you to reach the Adamantine Forge waypoint. Once you discover this, your party can fast-travel to it. At this waypoint, you will find some enemies along with different kinds of moulds lying around. Grab as many of them as you can find, as they are paramount to working the forge. There is a Mace, Splint, and Scale armor mould in the direct vicinity around the waypoint.
To find the Mithral ore, which is the second piece you need to activate the forge, follow the steps below:
At the forge, you will see a crucible, a mould ejection lever, and a mould chamber. Follow these steps below:
This will spawn the Grym enemy, a giant construct with over 200 health. If you examine the Grym, you will see it has no weaknesses. In order to beat this enormous enemy, you need to ensure it is in the lava so it becomes Superheated. Then, you want to get one of your characters on the mould chamber and another one of your characters near the forge lever that descended the platform.
With this setup in place, you’ll need to follow the next steps in order to defeat the Grym:
If all goes right, the Grym will take massive damage and fall down. You need to repeat this process to kill it. Once that happens, you will be able to take your weapon or armor from the mould chamber. This will be of Adamantine variety, which allows the wearer or wielder to avoid all critical hits.
Unfortunately the shining set does not include a helmet, but the rest is stunning and a great medium armor for your playthrough! That’s everything you need to know about reaching and using the Adamantine Forge in Baldur’s Gate 3. The forge is reusable as long as you have another mould and more Mithral Ore. You can find another bit of ore right near the forge waypoint. I myself made the Scale Mail armor and a Mace for my Paladin, which looks fantastic as a set.
