How To Activate And Use Adamantine Forge In Baldur’s Gate 3

Want state of the art Adamantine Gear in Baldur's Gate 3? Follow us for a journey of lifetime through Underdark.

The Adamantine Forge is hidden behind Grymforge in the Underdark and allows you to craft Adamantine Weapons in Baldur’s Gate 3. This lava-infested place is hard to find and even harder to use due to the forge protector known as Grym.

FYI

Following our guide will also help you complete The Adamantine Forge side quest.

In this guide, we will teach you how to safely reach the Adamantine Forge and use it to craft some of the best early-game weapons with Mithral Ores in Baldur’s Gate 3.

Adamantine Forge Location in Baldur’s Gate 3

The journey to Adamantine Forge begins with finding the Grymforge. It is west of the Underdark, and you can reach it by using the Duergar Boat after killing the intruders. Once you reach the Grymforge waypoint, go up the stairs and travel North until you encounter a cave-in (X: -671, Y: 442).

Duergars are standing with their slave, Deep Rothe. They are also looking for a mysterious forge behind the cave-in but are now stuck. Talk to the Deep Rothe using the Speak with the Animal spell and kill their masters. Now clear the cave-in with the help of Deep Rothe to proceed.

Now, use the ladder on your left to go down and jump on a suspended platform. From here, you can find the Longsword Mould. Keep going forward until you reach another platform with two levers.

Hit the lever on the right with a ranged weapon to lift the platform. Now, get on the platform and hit the lever on the left. This will make the platform move forward. Once you reach your destination, jump down and continue North to find huge stairs. Climb them to find and enter the Adamantine Forge.

There is another method of reaching the Adamantine Forge much more quickly if you have the Misty Step spell available. From where you freed Nere from the cave-in (or killed him), go left to see a rocky platform past lava (X: -618, Y: 320).

Go to the other side, and you will notice a large gear on a ledge. This distance can only be covered with the Fly or Misty Step spells. You can also loot the Splint Mould from this ledge to craft Adamantine Splint armor. Walk across the boulder (it is lodged in the ground so you can climb it easily) and you will a small set of stairs to the left.

Cross the stairs and go straight to find the Ancient Forge waypoint. Call your companions and turn around to find a massive set of stairs. There is a Mithral Ore node to the left that you can mine. Keep going straight on the stairs to reach Adamantine Forge.

How to Use the Adamantine Forge

The Adamantine Forge in Baldur’s Gate 3 is basically a massive steel platform standing on a lava bed. It has three sections. Mould Chamber, Crucible, and the Forge Lever. You will need at least two items to use the forge to craft the desired gear.

  • Adamantine Mould, which goes into the Mould Chamber.
  • Mithral Ore, which you can place in the Crucible.

Once you place both items, pull the forge Lever to start crafting. The lava level will rise, and you need to steer clear of the area. Before picking up the gear item, you must face the forge protector, Grym.

FYI

Make sure to save before you craft any items. Adamantine Forge is prone to bugs and can get stuck. The only solution is to reload the game.

Grym is a mechanical construct whose sole purpose is to stop intruders from using the Adamantine Forge in Baldur’s Gate 3. This enemy is immune to all kinds of damage until you put him in a superhot state. This can be done if he stands in the lava for a few seconds.

Grym has 300HP, and it hits like a truck. Disband your party and make them all stand on different raised platforms. One party member must be present on the platform with the Forge Lever. Grym gets extra violent against the person who attacks it.

Use your tank (Bg3 tank build) to attack Grym while raising the lava with Forge Lever. It stays there for three turns and keeps Grym in a constant superhot state. This is your best of defeating this level 8 monstrosity. Once you defeat Grym, you can collect your Adamantine Gear item. Some of our favorites are
