Hollow Knight Silksong Exhaust Organ Bench Location Guide
The Exhaust Organ is a vent-filled area reached after escaping the Mists, and it hides one of the most important benches in Act 2. This Hollow Knight Silksong Exhaust Organ Bench guide shows exactly how to reach the bench, what dangers to expect, and the boss fight tied to the area.
How to Reach the Exhaust Organ
To get to the Exhaust Organ, you first need to escape the Mists. This looping zone has no map and traps players until the puzzle is solved. Use the Needlevin on glowing butterflies, wait for them to react, and follow their path to the correct exits.
Repeat this across multiple sections until you reach a checkpoint flat area. After one or two more sequences, the path leads directly into the BileWater’s Exhaust Organ.
Where to Find the Exhaust Organ Bench
Once inside the Exhaust Organ, head left and use a double jump to reach a higher platform. The Hollow Knight Silksong Exhaust Organ bench is located here, giving you the first safe rest point in this area.
This bench is critical because the vents ahead are packed with shifting air currents. Sitting here ensures you don’t lose progress if you get caught by hazards deeper inside.
Side Path: Flea Shortcut
From the bench, continue through the organ vents and look for a platform on the left. A flea NPC can be freed here, adding to the caravan storyline. This shortcut also makes returning through the area easier.
Phantom Boss Fight
The final challenge of the Exhaust Organ is the Phantom boss. She fights with a needle that doubles as a weapon and mobility tool. Her main mechanic is a parry stance; if you attack during it, she counters with a combo.
As the fight escalates, Phantom adds diving slams across the arena. Keep moving, bait her parry, and punish only when she leaves herself open. Defeating Phantom ends the Mists curse, unlocks a new skill, and clears the way into Act 2.
Final Blurb
The Hollow Knight Silksong Exhaust Organ bench is the key checkpoint after escaping the Mists. It anchors exploration in one of Pharloom’s toughest areas, sitting just before the Phantom boss. Unlocking this bench makes the climb safer and secures progress into Act 2.
