How To Get The Repellent In Blue Prince

Mastering the Repellent item provides game-changing control over your mansion’s layout in Blue Prince. This rare utility tool enables strategic room management that can significantly impact your long-term progression.

When activated with the ‘X’ key while in your inventory, the Repellent temporarily removes any eligible room from both your mansion and drafting pool for seven in-game days. This creates temporary space and removes unwanted room placements from your available options.

Note that certain critical rooms maintain immunity to the Repellent’s effects—specifically the Entrance Hall and Antechamber cannot be affected. However, this limitation becomes strategic when you understand its interaction with permanent mansion fixtures.

Critical Insight: The Repellent serves as the exclusive method for relocating your Foundation in Blue Prince.

The Repellent might appear in the Lost and Found.

Acquiring the Repellent requires either persistence with random chance or executing a specific multi-step strategy. Both approaches have distinct advantages and resource costs.

There are two primary methods to obtain the Repellent in Blue Prince:

• Lost and Found – As an exceptionally rare item, the Repellent has minimal appearance rates in the Lost and Found:
  • The Lost and Found represents an unlockable Floorplan that becomes available through mansion expansion.
  • Each entry into this area carries risk—you forfeit one random inventory item upon access, making repeated attempts costly.
• Foundation Outer Room Method – This reliable approach bypasses RNG dependence through careful planning:
  • First, unlock the West Gate Path by accessing the Garage Door and detaching the gate’s securing latch.
  • Next, draft the Shrine as an exterior room and secure the Monk’s Blessing, which permits drafting mansion rooms as outer rooms when concluding a day within them.
  • Complete your day’s activities while positioned inside the Foundation’s boundaries.
  • The following day, the Foundation becomes available as an outer room drafting option.

Since the Foundation maintains permanent status with fixed positioning, it persists as an outer room selection indefinitely. Mrs. Babbage responds to this unconventional drafting by leaving both a humorous note in the Entrance Hall and a guaranteed Repellent on the table.

When deploying the Repellent on the Foundation, it vanishes temporarily. Simply advance time for one full in-game week, after which the Foundation reappears in your drafting pool ready for placement in a new location.

Babbage will chide you for drafting the Foundation outside, but she’ll also give you a repellent.

Relocating your Foundation represents one of the most impactful strategic decisions in Blue Prince. The initial placement you selected might prove suboptimal as your mansion expands and your strategic needs evolve.

Perhaps you positioned the Foundation in row six or beyond—while this provides proximity to the Antechamber/Room 46, it necessitates extensive pathway drafting to reach. As a permanent room immune to reset mechanics, inconvenient Foundation placement creates persistent navigation challenges across future playthroughs due to randomization factors.

Advanced Strategy Tip: Foundation placement significantly influences your Class Guide efficiency by determining travel time between key locations.

Common Mistakes to Avoid:

• Moving Foundation too early before establishing critical room connections
• Failing to account for future expansion when selecting new Foundation location
• Underestimating the one-week cooldown period’s impact on your progression timeline
• Overlooking the resource cost of redrafting pathways to the relocated Foundation

The decision ultimately rests with your playstyle and mansion design goals. Consider the Repellent as your strategic solution when navigating to a distant Foundation becomes consistently problematic.
