Free Bellhart, then visit Pinmaster Plinney for Hornet’s first, free Needle upgrade. To upgrade it further, accept his Pinmaster’s Oil Wish before turning in Pale Oil. You can find Pale Oil through the Whispering Vaults, the Great Taste of Pharloom Wish, and the Act 3 Ecstasy of the End flea festival.
How to get the first Needle upgrade
- Travel through Shellwood and defeat Widow to free Bellhart.
- Go to Plinney’s workshop on the upper-right side of town and speak to him. He gives Hornet the first upgrade, Sharpened Needle, for free.
- Speak to Plinney again and accept the Pinmaster’s Oil Wish before handing him any Pale Oil. The Wish can be missed if you turn in Pale Oil before accepting it.
Where to find all three Pale Oils
Each Pale Oil enables one later Needle upgrade. The first two sources are available in Act 2; the flea festival reward is an Act 3 objective.

Return to Plinney for each upgrade
Bring each Pale Oil to Plinney in Bellhart. The upgrade sequence and damage values listed by the community-maintained Hollow Knight Wiki are:
| Needle stage | Damage listed by the wiki | Requirement | Rosary cost listed |
|---|---|---|---|
| Sharpened Needle | 9 | First upgrade; free | Free |
| Shining Needle | 13 | Pale Oil | Not stated |
| Hivesteel Needle | 17 | Pale Oil | 450 Rosaries listed by the Hollow Knight Wiki |
| Pale Steel Needle | 21 | Pale Oil | 680 Rosaries listed by the Hollow Knight Wiki |
The cost reporting is inconsistent. PC Gamer describes the third upgrade as around 500 Rosaries and later costs as roughly 500; Nintendo Life lists 500 for the third upgrade and 900 for the fourth. The Hollow Knight Wiki lists 450 and 680 for the third and fourth upgrades. These sources do not establish whether the differences come from a patch, guide error, or another condition, so check the current in-game price with Plinney rather than relying on an exact total.

Which Pale Oil route should you do first?
- Want a Citadel exploration route? Follow the Whispering Vaults path through Cogwork Core; it involves a platforming route and block puzzle.
- Already working on Wish ingredients? Complete Great Taste of Pharloom by gathering its five ingredients.
- In Act 3 and rescuing fleas? Continue to the flea caravan in the Putrified Ducts and take on the festival minigames. This reward comes later than the other two sources.
Plinney’s in-game reaction to receiving the Citadel Pale Oil is: “Welly, ho! That oil! You have it! That rare substance, hoarded close by the Citadel. Few are the pinmasters of our age that ever chanced to work its wonders.” The line is transcribed on the community-maintained Hollow Knight Wiki.
