Location of the Brain Puzzle

solve-the-bg3--brain-puzzle.jpg To locate the BG3 brain puzzle in Baldur’s Gate 3, players must first navigate to the Necrotic Laboratory, found within the Mind Flayer Colony. This area becomes accessible in Act 2, specifically at the southeast side of the map, with coordinates X: 736, Y: -113. Here, players will encounter a significant red chasm flanked by a command console crucial for initiating the puzzle.

Finding the Necrotic Lab

The Necrotic Laboratory is situated beneath Moonrise Towers, a dank and dark locale that houses the mind-brain connection puzzle. Access is gained by either reaching the end of the first hallway or proceeding to the next room after the Morgue.

Identifying the Console

Upon reaching the console within the Necrotic Laboratory, players are presented with a neural map of a brain. Interaction with this console is essential as it allows players to manipulate the mind by creating a neural network across multicolored nodes. The console projects various nodes and pathways where players must connect corresponding nodes without crossing paths, following the distinct color and shape of each starting node.

Solving the Brain Puzzle


The Neural Map

To tackle the BG3 brain puzzle, players first interact with a console that projects a neural map. This map displays four colored centers labeled as Speed, Emotion, Memory, and Reason. Each center must connect to its corresponding endpoint on the opposite side of a web of Neural Nodes.

Steps to Connect Nodes Correctly

  1. Start Simple: Begin by clicking on a center and then the node you wish to connect. Ensure no two centers share a node, maintaining individual paths.
  2. Work Sequentially: Tackle one pathway at a time to avoid overlaps. Use the bird’s-eye view (hit ‘O’) for a clearer perspective.
  3. Use Process of Elimination: If a center has only one possible node connection, that’s where it must go. This strategy helps in efficiently navigating the puzzle.
  4. Final Connections: Once all paths are correctly connected without crossing, the Flesh-Wrought Door unlocks, revealing further secrets and rewards in the game.

Post-Puzzle Actions

After solving the BG3 brain puzzle, players should proceed to the Mind Flayer monument revealed behind a newly opened door. This monument, significant from the game’s intro, houses the Waking Mind, a crucial item for further interactions.

Interacting with the Mind Archive Machine

Located close to the puzzle area in the Necrotic Laboratory, the Mind Archive Machine allows players to slot in the Waking Mind. Once inserted, players can interact with a Githzerai through the Slack-Skinned Head. The Githzerai offers a choice to purge their mind, granting the player a Githzerai Mind Barrier buff. This buff provides an advantage on all intelligence saving throws, enhancing the player’s abilities in future challenges within Baldur’s Gate 3.
