Where To Get Adamantine Slag
Adamantine Slag appears randomly in the Grymforge area. Some known spawn locations include the upper pathways in the abandoned Shar Temple and the area where you find the Smokepowder Reserve. Usually, it is found on corpses or lying on tables. Additionally, it can be obtained from the quest Get Past The Rubble. This quest is located at (x=-672, y=443).
How To Complete Get Past The Rubble
- To begin this quest, speak with the Duergar who are watching over the Deep Rothé in front of a cave-in. The Duergar will offer to pay you if you can force the animals to finish the job - they'll suggest you try whipping them.
- Speak to the Deep Rothe - here you'll have the option to hit them, or you can try animal handling to calm them down. If you can speak with animals, you'll get better dialogue options for this.
- Upon passing the first animal handling check, you'll have the option to ask them to finish the job or convince them to attack the Duergar. Either will progress the quest.
If you first clear the rubble, the Duergar will refuse to pay you and attack, causing the Deep Rothé to take your side. If you attack them, then you can still ask the Deep Rothe to clear the rubble afterward.
If, for some reason, you can't get the Deep Rothé to clear the path, you can access the area behind by attacking the rubble with Force damage (Smokepowder, Runepowder, or Shatter are all good ways to accomplish this). Alternatively, you can stack crates and barrels to jump over the rubble.
How To Use Adamantine Slag
Like many items in Baldur's Gate 3, Adamantine Slag only exists to allow you to interact with the world and learn about it. Despite its name, Adamantine Slag has no use in the Adamantine Forge nor any other mechanical use. This is alluded to in its flavor text. Instead, you will need to obtain Mithril Ore and one of the several molds scattered around Grymforge to make Adamantine Gear.
However, that doesn't mean there aren't non-mechanical ways to use Adamantine Slag. Players can sell it (1 gold each) for a little bit of cash or use it as a camp decoration. Alternatively, some players even opt to carry it around because it has practically no weight to it and thus doesn't affect inventory management.
