Despite offering a near-endless supply of game-changing choices, Baldur's Gate 3 ironically offers few options when it comes to crafting new gear. Most of the items you can craft are part of the same side quest: The Adamantine Forge, which allows you to craft six Adamantine Forge items.
Best Adamantine Gear | BG3
The Adamantine Forge is an optional questline in BG3 that takes place towards the end of Act One, as players prepare to enter the Cursed Shadow-Lands via the Underdark. The quest begins in Grymforge, an ancient city now inhabited by Duergar, and concludes with the option to craft two Adamantine Items in the forge beneath the city.
While you can only craft two pieces of gear, there are six options: three pieces of armor and three weapons.
For each piece there is a mold, which you must find in the area around the Adamantine Forge (in the description of each piece we explain where to find the molds).
