In Baldur’s Gate 3, you’ll come across a significant obstacle in the Grymforge Cave: a massive cave-in that needs to be cleared. But fear not, for with the right tools and knowledge, you can blast through this blockade and continue your adventure. In this guide, we will discuss everything you need to know on how to clear the rubble after getting the Smokepowder Bombs in Baldur’s Gate 3.


Where To Find The Smokepowder Bombs

Hidden within the depths of Grymforge lies a secret room, tucked away in the eastern part. From the Underdark-Grymforge waypoint, if you head east and choose the door to the left instead of ascending the stairs, you’ll find yourself in a room filled with remnants of the past. A keen eye and a successful Perception check will reveal a concealed button near a pillar. Pressing this button unveils the secret chamber where two Smokepowder Bombs await behind a chest.

Philomeen and the Runepowder Vial

The enslaved individuals near the cave-in will hint at Philomeen’s involvement in a prior explosion. Engaging in the right dialogue with her can reward you with a vial of Runepowder, a powerful explosive. Philomeen can be located by starting at the locked room northeast of the Grymforge waypoint (X:-537 and Y:437). A Perception check will unveil a hidden button, leading to a path where you’ll face off against three Ochre Jellies. Overcoming them and continuing on will bring you face to face with Philomeen. Choose your words wisely, and the Runepowder Vial can be yours.

Dialogue Options To Get The Runepowder Vial

Engaging Philomeen in conversation requires a delicate touch. Here’s a suggested dialogue path to secure the Runepowder Vial:

  1. Calm Down. Let’s talk this through.
  2. [Persuasion] Laridda sent me. The gnomes need your help.
  3. I’m not taking you anywhere. You’re free to go.
  4. What I want is your help. Beldron’s trapped—I need the smokepowder.
  5. [History] Ironhand. Runepowder. Where have you heard these terms before? (A roll of at least 20 is needed to pass)
  6. Runepowder? I thought that was a children’s story.
  7. I’ll need to know a little more about your so-called ‘mission’ before I let you go.
  8. What use is a single vial?
  9. Deal.
  10. Where will you go now?

How To Blow Up Rubble In Grymforge Cave

With the Smokepowder Bombs and Runepowder Vial in hand, you’re equipped to tackle the cave-in. The key is to throw these items as close to the cave-in as possible and then ignite them using a fire spell, such as Fire Bolt. If you’re not magically inclined, companions like Gale or Astarion can step in for the fiery finale. Ensure the area is clear of any bystanders to prevent unintended casualties. If you’re feeling particularly explosive, adding an extra Smokepowder Bomb or barrel can amplify the blast.

Alternative Explosive Methods

While the Runepowder Vial is a potent tool, those who prefer a more direct approach can rely solely on Smokepowder. However, bypassing the side quests means missing out on assistance from the slaves and Philomeen in the aftermath of the explosion. The choice is yours, but aiding them often feels like the morally right decision.
