In Hollow Knight: Silksong, enhancing your primary weapon, the Needle, is key to success. This is achieved through the use of Pale Oil, a rare resource scattered throughout the Kingdom of Pharloom. This guide will detail the locations of all Pale Oil required for Needle upgrades, transforming your weapon from a modest tool to a devastating force.
Obtaining Your First Upgrade in Bellhart
Your journey begins in Bellhart, a settlement nestled between Greymoor and Shellwood. Here resides Pinmaster Plinney, the artisan who will upgrade your Needle. However, Bellhart is under a curse, and its inhabitants are hidden until the curse is lifted by defeating the Widow boss in the upper reaches of the town. This is a main story objective, so you won't miss it. Once the curse is broken and the townsfolk reappear, locate Pinmaster Plinney in the bellhome on the right side of the chamber and receive your first free upgrade.
Pale Oil Location #2: Whispering Vaults Crate Puzzle
The second Pale Oil is found within the Whispering Vaults sub-zone of the Citadel. In a large room to the left, you'll encounter a puzzle involving several crates. By strategically striking the crates, you create a path leading to an exit on the left. Observe the horizontal and vertical beams in the background; they indicate the direction the crates will move when struck. Successfully solving this puzzle will reward you with your second Pale Oil.
Pale Oil Location #3: Choral Chamber and the Great Taste of Pharloom
The third Pale Oil requires the completion of the 'Great Taste of Pharloom' quest. This involves gathering five unique ingredients from various locations across the game world: Mossberry Stew from Mosshome, Vintage Nectar from Greymoor, Pickled Muckmaggot from Sinner's Road, Crustnut from Sands of Karak, and Courier's Rasher from Bellhart. Once all ingredients are collected, deliver them to the designated location to receive your reward: another Pale Oil for your Needle upgrade.
Pale Oil Location #4: Fleatopia and the Lost Fleas
The final Pale Oil is acquired in Fleatopia, but obtaining it is a multi-stage process. This involves several significant steps: First, rescue all 30 Lost Fleas. Then, locate the final moving site for the Flea Caravan in the Putrefied Ducts. Progress the main story until you unlock Act 3 by completing the 'Silk and Soul' quest. Once Act 3 begins, return to the Flea Caravan in Putrefied Ducts and speak with Mooshka. A new quest, 'Ecstasy of the End,' will appear on the wish board in Bellhart. Finally, return to the Flea Caravan, participate in their celebration, and win all the minigames to claim your final Pale Oil and fully upgrade your Needle.
With all four Pale Oils collected, your Needle will be significantly enhanced, boosting your combat prowess throughout your journey in the Kingdom of Pharloom. Remember to visit Pinmaster Plinney in Bellhart after each Pale Oil acquisition to apply the upgrade.
