Baldur's Gate 3: How to Fix Stuck Lava Valve in BG3

Spin that valve and unveil your prize

The Grymforge is as its name suggest: grim. And also, a forge. But beyond that, it has its fair share of secrets, including a method to create some of the best Act 1 armor in the game and a boss that can cough up some very rare equipment if you know what to do. But to get that far, you’re going to need to tackle the stuck lava valve. Here’s how to fix the stuck lava valve in Baldur’s Gate 3.

Get as far as the Adamantine Forge and you’ll find that there’s a massive machine. This machine can craft you three types of armor, but to do so you’ll need to fix the stuck lava valve.

And, fortunately, doing so is pretty straightforward. Here’s how to fix the stuck lava valve in the Adamantine Forge in Baldur’s Gate 3, with a more in-depth explanation below:

Moulds are scattered across the area, but the easiest to find are those that are near the Adamantine Forge waypoint. As for Mithril Ore, there are two located not far from the Adamantine Forge, which are marked here on the map.

To insert the Mithril Ore, press the Mould Chamber. A menu will pop up. Next, open your inventory and find the Mithril Ore. It will be on the character you used to pick it up. Drag the Mithril Ore into the menu box, then press insert.

Once you have all the pieces in place, pull the lever and you’ll descend without issue. You can then turn the lava stuck valve.

Now, get ready for a boss fight that can be pretty challenging if you don’t know the right strategies to take it down.
