Baldur’s Gate 3: How to Blow Up the Grymforge Cave after Freeing Nere in BG3

What could be behind that wall?

Grymforge is a much bigger area than you might imagine, full of twists and turns behind locked doors and cave rubble. Behind one pile of rocks is True Soul Nere, the drow whose head you’re meant to bring back to Sovereign Spaw at the Myconid Colony. However, there’s actually another cave-in within Grymforge that leads to something even more exciting. But without any means to clear the rubble, how are you supposed to get through? Here’s how to blow up the second Grymforge cave-in and find the Adamantine Forge in Baldur’s Gate 3.

Baldur’s Gate 3: How to Blow Up the Sturdy Wall and Find the Adamantine Forge

To blow up the second Grymforge cave-in, you need to throw Smokepowder Bombs at it, which can be purchased from Derryth Bonecloak in the Myconid Colony. You may remember Derryth as the dwarven trader searching for her lost husband after he went mushroom hunting. She holds two Smokepowder Bombs for sale, so grab both of them for 76 gold.

Where to Find the Second Cave-In in Grymforge

The second cave-in is located on the north side of Grymforge. Head north from the Underdark – Grymforge waypoint to find it, seen on the map image below. You’ll know you’ve reached it when you see a pile of rubble called a “Sturdy Wall”.

Normal attacks and most spells won’t work on the Sturdy Wall. You’ll need something that packs a lot of force. Luckily, Smokepowder Bombs do the trick nicely.

Where to Find Smokepowder Bombs

You can find Smokepowder Bombs in various places, but the easiest method of obtaining them is to purchase them from Derryth Bonecloak in the Myconid Colony. You’ll find her at the (X:55 Y:93) coordinates next to a Deep Rothe animal.

If you’re unable to find Smokepowder Bombs from Derryth, just try checking other vendors. There’s another within the same Myconid Colony, plus several others you’ve surely passed in your journey so far.

Once you’ve obtained at least two Smokepowder Bombs, return to Grymforge and head to the cave-in. Open your inventory, right-click the bombs, and click Throw. Make sure to keep your distance from the wall, as the bombs will do splash damage. After chunking two bombs at the rubble, the path will be clear, leading you towards an entirely new area of Grymforge.

If the large pools of lava in the next area weren’t obvious enough, you’re heading toward the Adamantine Forge. To use it, you’ll need to do a bit of prep work. Check out our guide on how to use the Adamantine Forge in Baldur’s Gate 3 so you can craft some exquisite gear.
