The Baldur's Gate 3 Adamantine Forge can make weapons and armor from Mithral Ore and moulds if you can hunt down their locations and work out how to use the forge itself - as well as how to destroy Grym, the giant construct that guards the forge. I've managed to find all the ore and moulds in BG3 and beat Grym, so below I've assembled a full guide on how to find and use the Adamantine Forge in Baldur's Gate 3 - whatever you need to know is explained below!

The Adamantine Forge in Baldur's Gate 3 is located south of Grymforge, the area taken over by the Duergar that you reach by finding their boat in the Underdark. However, the Duergar haven't made it there either, and can't help you find it. To reach the forge, you need to do the following:

The Adamantine Forge is a complex device that requires Mithral Ore and a Mould of whatever weapon or armor you want to make. There's also multiple interactive sections that you can see when you press the Baldur's Gate 3 highlight objects button. Here's how to make something in the Adamantine Forge:

Keep in mind that you'll need a fresh piece of Mithral Ore each time, and have to eject and insert a new Mould if you want different equipment (though there's nothing stopping you from making the same weapon or armor multiple times if you're so inclined). Though speaking of Moulds and Ore, where do you even get this stuff?

There are six Moulds to find in Baldur's Gate 3, each one for a different weapon and piece of armor. All of them are in the Grymforge area, though they're spaced out, and not all equally easy to obtain.

Here's how to find all the Moulds in Baldur's Gate 3:

At time of writing there are only two locations we know of to obtain Mithral Ore, but they're both close to the Forge itself.

The locations of the Mithral Ore in Baldur's Gate 3 are:

Because there's only two Mithral Ores to get, this means you can only use the Adamantine Forge twice in the whole game, despite the fact there's six various Moulds and potential creations. This means there's a hard choice to be made - pick carefully!

The first time you try to use the forge, turning the Lava Valve will also release Grym, a giant Mithral construct who guards the Adamantine Forge. Grym has massive amounts of health, but there is actually a secret way to do big damage to him, a sort of puzzle.

Once destroyed, Grym won't come back, and you can loot his body for a rare Adamantine Helmet. You can also keep using the Forge - this time without being attacked by Mephits or scary giant magical robots, thankfully.
