Rescuing True Soul Nere in Baldur's Gate 3 is one of the most critical quests in the Grymforge region. Trapped behind a massive cave-in filled with toxic gas, Nere will suffocate if left unattended for too long. Understanding how to clear the rubble safely and manage the surrounding factions ensures a smooth path forward in your Underdark campaign.

Locating standard and specialized explosives

To break through the heavy cave-in, players need high-yield explosives capable of shattering rock. While standard smokepowder bombs found around the map work, track down the runaway deep gnome Philomeen for stronger options. Negotiating with Philomeen grants access to powerful runepowder, which creates a massive explosion that instantly clears the blockage.

If you prefer saving rare resources, multiple smaller smokepowder satchels hidden throughout Grymforge can accomplish the same task. Always ensure you place the explosives directly in front of the pile. Distancing your party before detonating prevents accidental damage to your companions or the nearby gnome workers.

Clearing the rubble safely

Once your chosen explosive is in place, command the surrounding gnomes to back away. Use a fire cantrip, a burning arrow, or a ranged attack from a safe distance to trigger the blast. The resulting explosion removes the debris and frees True Soul Nere from his cavernous prison.

Timing is crucial during this operation because taking too many long rests causes Nere to perish in the cave-in. Plan your preparations carefully before approaching the main chamber to avoid failing the rescue objective.

Managing the duergar alliance

Before releasing Nere, players can speak with Elder Brithvar near the entrance stairs to forge a secret pact. Aligning with Brithvar allows you to turn a portion of the duergar mercenaries against Nere. This strategy significantly reduces the difficulty of the impending battle.

Alternatively, players who choose to support Nere must fight off the rebellious mercenaries instead. Careful preparation before clearing the rubble gives you full control over which faction dominates the aftermath.

Confronting Nere and concluding the quest

Immediately following the explosion, a cutscene triggers where Nere emerges and addresses the remaining survivors. Depending on your moral choices and prior alliances, you can choose to execute him or join his cause. Deciding his fate shapes your story progression and awards valuable loot, including an Mind Flayer parasite.

Successfully navigating this multi-step encounter completes the Grymforge rescue operation and grants substantial experience points. Resolving Nere's situation clears the path toward the Shadow-Cursed Lands.
