The Baldur's Gate 3 windmill and the Mind Flayer encounter within it present a tricky situation, often requiring a specific sequence of actions.
The Windmill Puzzle
- Stop the Blades: Initially, the windmill blades are turning, powering the machinery inside. You need to stop them.
- Inside the Mill: Head inside the windmill. You'll find two goblins and a brake lever.
- Brake Lever Options: There are typically a couple of choices to stop the windmill:
- Use the brake lever directly (requires a Strength check).
- Convince the goblins to stop the windmill. This could be through intimidation, persuasion, or deception.
Mind Flayer Encounter
Stopping the windmill reveals a hidden passage leading to an underground area.

- Investigate the Passage: Enter the newly revealed passage. This will trigger an encounter with a Mind Flayer and potentially other enemies.
- Prepare for a Fight: Mind Flayers are formidable opponents. Psychic damage resistance/immunity is helpful. Having characters with good crowd control abilities is also recommended.
- Tactics: Focus fire on the Mind Flayer. Use spells and abilities that can stun, incapacitate, or otherwise control it.
- Loot: After defeating the Mind Flayer, be sure to loot the area for valuable items and equipment.
Important Considerations:
- The exact details of the encounter (enemies, loot) can vary slightly depending on your game's difficulty and choices.
- Saving before attempting the brake lever or entering the passage is always a good idea.
