Volt Filament is one of the tools that Hornet can use in her Hollow Knight: Silksong journey. It's an Act 3 tool, as getting the Volt Filament tool requires using abilities only available in that Act. Here's everything you need to know about Volt Filament in Silksong, including its location and how to get it.
Courier's Rasher Quest Guide In Silksong
The Courier's Rasher delivery quest in Hollow Knight: Silksong not only tests players' damage-dodging skill, but also limits their travel time.
Volt Filament Location In Silksong
You can find Volt Filament in the Sands of Karak region, right above Blasted Steps in Silksong. It's in a hidden area that can only be accessed after getting 
Silk Soar, which is a Super Jump skill.
If you haven't unlocked Sands of Karak yet, you need to travel to the west of Blasted Steps to enter Sands of Karak for the first time. From there, you can open a shortcut right above Blasted Steps' Bellway in Silksong.
To get the Volt Filament tool, teleport to the Blasted Steps' Bellway and climb up to reach the Sands of Karak region. If you didn't unlock the bridge shortcut on top of Sands of Karak, you'll have to take a long road to the right and come back on top of the bridge to create the shortcut.
Once you reach the bridge, trigger the Silk Soar ability to reach and enter the Voltnest, which is on top of the Sands of Karak region.
Once Hornet is inside the Voltnest, you can explore the area or navigate inside to reach the area's boss, Voltvyrm. Just like how unforgiving electrical attacks in Voltnest are, Voltvyrm is very aggressive and will keep coming at Hornet with all the electrical attacks.
However, just like how strong Voltvyrm's attacks are, it's also weak to damage and will keep retreating to another place whenever Hornet lands a hit. In the end, Voltvyrm dies faster than most bosses. So, keep avoiding its attack while having something that auto-attacks it, like the 
Wispfire Lantern or Cogfly tools in Silksong.
After beating Voltvyrm, you'll get the Volt Filament tool in Hollow: Knight Silksong. It's a decent tool that increases the damage of Silk abilities and makes them electrical. You can maximize the Volt Filament effect by using it on the Shaman crest, as it has three Silk abilities.
