So you’ve booted up Hollow Knight: Silksong in 2026, stared at the controller settings, and noticed a mysterious little entry called Needolin . Congratulations — you’ve just discovered one of the game’s most charmingly weird abilities. And no, it is not a musical instrument DLC. It is a proper Ancestral Art, and it is absolutely worth hunting down.

I’ll be honest: my first encounter with Needolin was pure confusion. I pressed the button, Hornet started strumming, my Silk bar quietly drained, and I sat there like a fool waiting for something dramatic to happen. Nothing did. Then I tried it next to a locked circular gate, and suddenly I felt like a genius. That’s the Needolin experience in a nutshell — useless until it’s indispensable.

What Needolin actually does

Needolin is an Ancestral Art that lets Hornet play a song. By default, you hold D on PC, Triangle on PlayStation, or Y on Xbox. The song consumes Silk , so don’t spam it like a toddler with a kazoo. Here’s the short version of its talents:

Use case What happens

Bellway summoning Calls the Bell Beast so you can travel

NPC interactions Triggers special conversations and events

Circular gates Opens sealed Weavenest doors

Weavenest secrets Leads to ability-enhancing surprises

That last row is the spicy one. In Weavenest Atla , for example, you can find a strange figure who helps enhance Hornet’s abilities. I won’t spoil the whole encounter, but let’s just say the weird little guy is more useful than he looks.
