🗝️ How to Start the Save the Mind Flayer Prisoner Quest in BG3
Learn the first steps to trigger this optional prologue quest and locate the Mind Flayer prisoner in BG3.
🧭 Explore the Nautiloid After the First Battle
📍 Once you defeat the Sacrificed Cultists during the 
Escape the Nautiloid mission, you’ll be free to explore the ship’s corridors. During this exploration, you’ll encounter the start of the Save the Mind Flayer Prisoner quest in BG3. This quest automatically triggers when you approach the Mind Flayer Pod containing Shadowheart.
🔍 Where to Find the Mind Flayer Prisoner in BG3
🧬 The prisoner, Shadowheart, is located inside one of the pods in the third room of the Nautiloid (
X: 1 Y:-346), near a chamber filled with tentacles and arcane liquids. To activate the quest, interact with the console next to the pod. This officially begins the mission to rescue the Mind Flayer Prisoner and opens up new exploration and choice options.
⚙️ Activating the Console and Accepting the Quest
🛠️ When you attempt to free Shadowheart in BG3, the console will prompt you for a 
Eldritch Rune, a required item to initiate the rescue sequence. You’ll find it on an elevated platform to the east, on the corpse of a fallen thrall. Grab the rune, return to the pod, and interact again to unlock it and continue the mission.
🛡️ How to Save the Mind Flayer Prisoner in Baldur’s Gate 3
Learn the various ways to successfully complete the Save the Mind Flayer Prisoner quest in BG3 and rescue Umbralma before the ship crashes.
🧩 Use the Preternatural Rune
🔮 The most straightforward method to rescue Umbralma in BG3 is by locating and using the Eldritch Rune. It’s found in an upper room to the east, on the corpse of a Dead Thrall (X:62 Y:-351). Once collected, return to the pod’s console and insert the rune to release the prisoner. This approach is simple, safe, and accessible to any class.
💪 Use Class Abilities
⚔️ Another way to save the Mind Flayer Prisoner in Baldur’s Gate 3 is by leveraging your character’s class abilities. Barbarians can attempt to break the pod open with a 
Strength check, while Wizards, Sorcerers, or Warlocks can perform an 
Intelligence check. This skips the rune entirely, but requires passing the skill check.
🌀 How to Free Shadowheart in Baldur’s Gate 3
🗣️ Once Shadowheart is freed from the pod, she can temporarily join your party while you’re still aboard the Nautiloid. This decision triggers a series of events that will influence the game’s story in future acts. Freeing Shadowheart also unlocks unique dialogue options and can affect your relationship with companions like Lae’zel.
🧠 Consequences of Saving Shadowheart in Baldur’s Gate 3
🤝 Completing the Rescue the Illithids’ Captive quest in BG3 earns approval from Lae’zel, who values practical decisions and strategic alliances. Your interaction with Umbralma also affects your bond with Shadowheart, who has mysterious ties to the freed character. This rescue shapes future conversations and can open up unique narrative paths.
🌌 Shadowheart’s Presence in Act One
🧭 Saving Shadowheart allows her to reappear shortly after leaving the Nautiloid, aiding you from the start of Act One. She will return with different memories and reactions based on your actions in the prologue. These changes influence the story and may unlock special events. She remembers if she was rescued—or left behind—and behaves accordingly.
⚠️ What Happens If You Don’t Save Shadowheart?
😐 Ignoring Umbralma may seem inconsequential at first, but you’ll miss out on exclusive interactions and the temporary ally she could have been aboard the Nautiloid. Additionally, your reunion in Act One will be colder and more distant, limiting potential narrative depth.
☠️ What If You Kill Shadowheart in BG3?
💀 Taking an extreme path and killing her during the prologue triggers a mysterious scene: a magical object flies toward you, initiating a cryptic subplot that will follow you for some time. This choice directly alters future events and adds a darker tone to your adventure.

Command: Drop at a specific point during the Nautiloid escape. Here’s how.
