In the world of Baldur’s Gate 3, magical equipment is the key to survival and success. While most players are preoccupied with scavenging for hidden treasures, there’s an exception to the rule: crafting. The Adamantine Forge, tucked away in the Underdark’s depths, can transform Mithral Ore into formidable equipment that can turn the tide of battle in your favor.
In this guide, we’ll delve into the art of crafting with the Adamantine Forge and uncover the secrets to creating powerful gear.
How to Mine Mithral Ore in Baldur’s Gate 3
Before you can wield the Adamantine Forge’s power, you must first obtain Mithral Ore. Mining Mithral Ore is very straightforward. You simply whip out Shadowheart’s mace or any blunt weapon and hit it a couple of times.

Follow these steps:
- Locate a Mithral Vein: There are only 3 Mithral veins known to us, and both are found near the Adamantium Forge. Keep an eye out for their distinct blueish glow, which sets them apart from ordinary rocks. Below, we’ve included a quick guide to finding Mithral Veins.
- Equip a high-damage bludgeoning weapon: Mithral Veins are tough, with resistance to most damage types. To effectively mine Mithral Ore, you’ll need a character equipped with a high-damage bludgeoning weapon.
- Attack the Mithral Vein: Engage the Mithral Vein in combat, chipping at it until its HP is depleted.
- Loot the Mithral Ore: Once you’ve destroyed the Mithral Vein, claim your reward by looting the Mithral Ore it leaves behind.
Remember that only bludgeoning damage can penetrate the defenses of a Mithral Vein, so choose a character with high strength to do the heavy lifting.
Where to Find Mithral Ore in Baldur’s Gate 3
Efficiency is key when seeking Mithral Ore. Players who are wondering where to find Mithral Ore veins likely find themselves in the vicinity of the Adamantine Forge. Conveniently, Mithral Ore can be found near the Forge, specifically on the west and east sides of the path leading to it. Here, you can acquire two valuable pieces of Mithral Ore.

However, it’s essential to note that you won’t be able to craft every possible piece of equipment, so choose wisely based on your party’s needs and strengths. Considering there are only 2 Mithral ore veins known to us, we suggest making two pieces of armor as the stats on both the Scale and Splint Adamantine armors are game-changing as you enter Act 2.
Confronting the Adamantine Forge Boss
The final hurdle on your path to crafting greatness is a formidable boss guarding the Adamantine Forge. Defeating this boss not only grants you access to the forge but also serves as a valuable lesson in harnessing its potential.

He might seem challenging with his 200+ HP, but there is a strategy here that should allow you to swiftly take him out:
- The Valve. Position one of your companions by the valve and make sure to keep the lava flowing to ensure Grym stays overheated.
- The Hammer. Position another one of your party by the lever that brings down the forge’s hammer. The other two can go on the remaining circles. Make sure to keep them out of the fire.
- The Baits. With your ranged attacks, try to lure Grym into the center of the forge. Once he’s on top of the forge, you can bring down the hammer with the lever, and, provided he’s still overheated, he’ll take somewhere around 100 damage from a single hit.
- Rinse and repeat.
Grym normally attacks the person who dealt damage to him last, so use that to your advantage. Summons are very useful here.
Once your party is equipped with equipment forged from Mithral Ore, taking on other challenging boss fights will become slightly more manageable.
In the world of Baldur’s Gate 3, the Adamantine Forge stands as a beacon of power and potential. Crafting magical equipment from Mithral Ore is a complex process, but with this guide, you’ll be well-prepared to face the challenges that lie ahead. Equip your party with the finest gear, confront the forge’s guardian, and venture forth stronger than ever.
Baldur’s Gate 3 is currently available for PC and PlayStation, with an Xbox Series X/S version still in development.
