In truth, Grymforge is quite grim. There are dead, slaves, and plenty of lava in this place. But the legendary Adamantine Forge eases the oppressive nature of the place. There are six moulds in Baldur’s Gate 3 that you can use to create your desired item. Here are all the mould locations.
In Baldur’s Gate 3, where can you find all the molds in the Grymforge?
Almost inevitably, you’ll stumble across the mythical Adamantine Forge while traversing the Grymforge. After defeating its guardian, you can claim two Mithril items if you have both Moulds and Mithril.
