How to light all four blue braziers in Blue Prince

The blue brazier puzzle represents one of Blue Prince’s most rewarding environmental challenges, offering players permanent progression benefits that persist across gaming sessions. Unlike many temporary solutions in the game, activating all four braziers grants permanent basement access that never resets, making this puzzle essential for long-term exploration and resource gathering.

Successfully completing this multi-stage challenge requires careful navigation through various house areas and strategic room development. The puzzle’s complexity lies not in the activation mechanics themselves, but in the systematic approach needed to reach all required locations throughout the mansion’s expansive grounds.

Begin your search from the Entrance Hall, proceeding directly to the outdoor Grounds area. Navigate left of the central Fountain feature and descend the staircase to discover all four blue braziers positioned together at the staircase’s base. Their clustered placement simplifies the final activation process once you’ve secured all necessary gasline valves.

Pro Tip: Mark this location on your mental map early, as you’ll need to return here after collecting each valve. The braziers’ proximity to each other means you can activate them all in one visit once you’ve gained control of the gas supply system.

Activating the braziers involves manipulating gasline valves scattered throughout the property. Turning these valves redirects gas flow to the corresponding brazier, causing automatic ignition. The puzzle’s complexity stems from valve placement rather than activation mechanics, requiring thorough exploration of both indoor and outdoor areas.

Each valve connects to a specific brazier through underground piping, meaning you don’t need to return to individual braziers after valve activation. The system’s design ensures that once you locate and turn a valve, its associated brazier will remain lit permanently, contributing to your progression toward basement access.

Two valves reside within accessible interior rooms, though reaching them requires solving preliminary puzzles. The Orchard valve becomes available after obtaining the access code from the Darkroom and unlocking the corresponding gate. Upon entry, immediately check your left side where the gasline valve awaits activation.

The Gemstone Cavern valve requires passage through the Utility Closet. Once you’ve gained entry, the valve sits just inside the cavern entrance on your right. This location often proves challenging due to the cavern’s maze-like structure, so careful navigation is essential.

Common Mistake: Many players overlook the Utility Closet requirement for Gemstone Cavern access, wasting time searching for alternative entry points. Always ensure you’ve completed the prerequisite room access steps before attempting valve collection.

The remaining two valves present the greatest challenge, located within special Outer Rooms that require construction. Access these areas by progressing through the Garage to unlock both the West Gate and connecting West Path. This external expansion provides the foundation for building additional rooms.

Once the West Path is accessible, you can draft rooms at the Outer Room door. Specifically target the Hovel and Schoolhouse during your drafting sessions. The game’s mechanics limit you to constructing only one Outer Room daily, meaning acquiring both target rooms may require multiple in-game days and strategic planning.

Optimization Tip: Prioritize room drafting based on your current progression needs. If you’re close to completing other objectives, consider delaying Outer Room construction until you can dedicate full attention to this puzzle. The Complete Guide offers additional strategic planning advice for similar multi-day challenges.

Successfully lighting all four braziers demands efficient route planning and understanding of game mechanics. Begin with the indoor valves (Orchard and Gemstone Cavern) while working toward West Gate access simultaneously. This parallel progression saves significant time compared to sequential completion.

When drafting Outer Rooms, maintain persistence through the daily limitation. The random nature of room drafting means you might not get your desired rooms immediately. Use unsuccessful drafting days to work on other objectives, such as weapon unlocks detailed in our Weapons Unlock guide or character development strategies from the Class Guide.

Time Estimate: Completing the entire brazier puzzle typically requires 3-5 hours of gameplay, depending on your familiarity with the mansion layout and efficiency in solving prerequisite puzzles. New players should allocate additional time for exploration and learning game mechanics.
