Crafting powerful gear in Baldur's Gate 3 requires finding rare materials hidden deep within the Underdark. Players exploring the Grymforge region will discover that forging Adamantine equipment requires Mithral Ore deposits rather than standard raw metal. Understanding where these deposits are situated and how to extract them ensures your party receives top-tier armor and weapons early in the campaign.
Locating the First Mithral Ore Deposit
The first deposit of Mithral Ore is situated near the pathway leading down toward the Ancient Forge. As you descend the stairs from the Ancient Forge waypoint, look to the left across a gap filled with flowing lava. Leaping over this hazard brings you directly to a large glowing blue ore vein.
Approaching this deposit triggers an ambush by Magma Mephits that must be defeated before mining. Once the area is clear, use a bludgeoning weapon or a pick to shatter the vein and collect your ore. This material serves as the essential component for your initial forge craft.
Finding the Second Mithral Ore Deposit
The second vein of Mithral Ore is positioned to the southwest of the Ancient Forge waypoint. Travel past the area guarded by Animated Armor enemies and carefully navigate the rocky path near the lava pools. Follow the safe ground through the magma zone until you locate another glowing blue rock formation.
Unlike the first location, this vein is not guarded by immediate enemy ambushes. Simply strike the ore deposit with bludgeoning damage to harvest the final piece available in the game. Because only two pieces exist across a single playthrough, choosing what to forge requires careful thought.
Essential Mining and Extraction Techniques
Mining Mithral Ore in Grymforge requires specific damage types to successfully break the deposit. Standard slashing or piercing weapons will prove ineffective against the tough mineral shell. Equipping a warhammer, mace, or pickaxe allows your character to deal sufficient bludgeoning damage to destroy the rock.
Alternatively, force-based spells or explosive items can also crack the deposit open efficiently. Ensure your party remains healed up, as hazardous lava surrounds both extraction points. Preparing resistance to fire damage can prevent unnecessary party wipes during extraction.
Best Crafting Tips for the Adamantine Forge
To use your harvested ore, you must combine it with specific gear moulds found throughout Grymforge. The Adamantine Forge allows you to craft heavy armor, medium scale mail, a shield, or various weapons. Most players find that crafting the Splint Armour or Scale Mail provides the highest long-term utility.
These armor pieces grant immunity to critical hits and apply debuffs to enemies that hit the wearer. Insert your chosen mould into the chamber, place the Mithral Ore into the crucible, and pull the lever to lower the forge. Operating the lava valve will trigger a challenging boss encounter with Grym, so prepare your party for combat.
