How to Get Volt Filament in Hollow Knight: Silksong

I’ve been tearing through Hollow Knight: Silksong in 2026, and I’ve got to say—Volt Filament is one of those tools that is easy to overlook but absolutely worth the detour. It’s an Act 3 tool, so you can’t grab it in the early game even if you’re feeling like a speedrunner on a hot streak. You need a specific ability first, and you need to know exactly where to poke around in the Sands of Karak. Let me break it all down, step by step, so you don’t wander around like a headless bug.

Silk Soar Is the Make-or-Break Skill

Let’s cut to the chase: you cannot reach Volt Filament without Silk Soar. This Super Jump skill is your golden ticket to the hidden area. If you show up without it, you’ll be staring at a ledge like a lost tourist—don’t bother. Make sure you’ve unlocked Silk Soar before heading out, because trying to reach the Voltnest without it is like trying to chop wood with a spoon. Pointless and a little embarrassing.

How to Unlock the Sands of Karak Shortcut

If Sands of Karak is still greyed out on your map, head to the west of Blasted Steps to enter the region for the first time. Once you’re inside, look for a shortcut right above Blasted Steps’ Bellway. Open that shortcut, because you’ll be bouncing back and forth, and the long way around is a real time sink. Trust me, your future self will thank you.
