Navigating the treacherous depths of Grymforge in Baldur's Gate 3 presents players with one of the most intense moral and tactical dilemmas in Act 1. True Soul Nere is trapped behind a cave-in filled with deadly poison gas, and saving him requires quick action and strategic planning. Whether you intend to align with him or end his life, freeing Nere is essential for progressing several key quests in the Underdark.

How to Clear the Cave-in and Free Nere

To free Nere, players must obtain powerful explosives to clear the heavy rubble blocking the collapse. The most reliable method involves tracking down Philomeena in the hiding spots around Grymforge to secure a barrel of Runepowder or Runepowder Vials. Alternatively, players can utilize Smokepowder Satchels or Bombs found throughout the Underdark to blow open the path.

Once you place the explosive near the cave-in, ensure all nearby deep gnomes step back to a safe distance before igniting it with fire damage. detonating the blast immediately opens the chamber and initiates a pivotal conversation with Nere as he steps out. Be mindful of the timer, as taking too many long rests after arriving at Grymforge will cause Nere to suffocate before you can intervene.

Siding with Nere or Turning Against Him

Upon his release, Nere immediately confronts the duergar mercenaries and gnomes, forcing your party to take a definitive side. If you choose to side with Nere, you must help him execute the rebels and gnomes, securing his favor and gaining insights into the Absolute cult. This path is ideal for evil or pragmatic playthroughs seeking alignment with the Moonrise Towers faction early on.

Alternatively, opposing Nere triggers a massive battle against him and his loyalists, allowing you to save the trapped gnome slaves. Players can also conspire with Elder Brithvar beforehand to turn a portion of the duergar mercenaries against Nere during the clash. Defeating Nere rewards players with his valuable True Soul Tadpole, his boots, and a powerful shadow-infused rapier.

Key Quest Outcomes and Consequences

The decisions made during Nere's rescue reverberate across future storylines in Baldur's Gate 3. Choosing to kill Nere pleases Sovereign Spaw in the Myconid Colony, opening up additional rewards and alliances in the Underdark region. Sparing the deep gnomes, such as Barcus Wroot, ensures their narrative arc continues into Act 2 and Act 3.

Conversely, supporting Nere isolates you from the Myconids and results in the tragic end of the local gnome community. Each choice offers unique story branches and party approval changes, making this encounter a defining moment in your adventure. Weigh your group's morality and tactical needs carefully before igniting the powder.
