Game Guide by Mash Rahman on Sep 26, 2025

Hunt or be hunted—that is the way of life in the world of Hollow Knight: Silksong. You face bugs and gods or godly beings. And amidst all this, you can advance to the extent that one can classify you as a godly being.

One of the items in my eye that allows you to have this godly level of damage output is the Voltvessel. In this guide, I will help you find the tool Volt Vessel in Hollow Knight: Silksong.

Where to Find the Voltvessels

To get the Voltvessels, you need to make your way to the area Memorium above the area Choral Chambers and make your way towards a hidden chamber near its upper section.

The tool is located behind a breakable wall, but reaching it requires precise platforming and surviving a combat encounter.

You have to make your way to the bench in Memorial. This will act as your checkpoint. Head to the right; you find a few enemies on the way to where you need to be. You can avoid fighting them by leaping over the enemies you see.

You will have to platform up by pogoing on the flowers and platforms scattered along the path. As you advance, you will start to encounter spike traps and sections where you have to break ceilings or walls covered in spikes, allowing you to pass into other sections.

Start moving to the left once you've scaled higher; you have to be aware of enemies that can push you into traps.

At a certain point, you will reach the start of a section that looks like Moss Home; I suggest dropping down here, as it will allow you to unlock a shortcut. This shortcut connects to the section on the left side of the Memorial bench, saving you time and sanity if you need to retry the upcoming arena fight.

Once you have it opened, continue your ascent, timing your movements around the shifting obstacles and hostile enemies. Here, the cling grip and claw-line come in handy for crossing the gaps.

As you ascend, you will notice that there are some pink and purple anemones on the wall to your right, along with a platform. You will need to get on that platform, break the glass, and enter the room.

Here, you will notice that there are a few columns of electricity flowing down from the ceiling. Here, you will have to wait for the first one to land and jump immediately after it does, and cling to the wall next to it.

After reaching this point, turn right. Here, you will notice a fragile wall at the top right corner, which is somewhat hidden and can be broken. Behind it lies a secret section, where an arena is located. It is the final challenge before obtaining Voltvessels.

In the arena, you will have to face two flying citadel enemies that throw these electric orbs that do damage in a circular area. I suggest that you try to stay mobile, using dash and clawline where necessary. You can dodge the Volt Orbs themselves by dashing away before they activate.

With nail upgrades, the enemies themselves shouldn't take many hits. If you don't have nail upgrades, try using Silk Skills and tools. Once you have defeated every enemy, you will have unlocked the Voltvessels tool.

Details On Voltvessels

Voltvessels are a versatile weapon that can change the way you play the game, transforming combat. The Voltvessels is a red tool, meaning it is supposed to function as a subweapon.

To use the volt vessel, you have to hurl the vessels like a bola to cause a circular electric explosion, or use them like a spear and stake them into walls and floors.

When a vessel sticks to a surface, it sends up a powerful column of electricity. In certain cases, the spear variant can even be angled diagonally by hitting the vessel. If the field of electricity touches water, it electrifies the surface, producing a wave of shock that damages anything standing on it.

The bola version allows multiple to be thrown at once, allowing you to get an immense damage output. Due to their number of uses, the bola versions are also very useful against larger enemies.

The vertical column allows you to strike enemies through ceilings, walls, and even water surfaces, making small enemy encounters much more manageable. Because it's a Red Tool, Voltvessels has limited charges and must be replenished at benches using Shell Shards.

A suggestion I can offer for using the Voltvessel is to use 3 or 4 for large enemies and 1 for multiple smaller enemies. This will cause you to not even need to hit them with your nail afterwards. This restrained use, rather than spamming it, will allow you to use it for longer periods.

The Voltvessel is also very useful in boss fights, as it allows you to output large amounts of damage in a small instance. And this is where the godly level damage output comes in.

Due to its massive damage, if timed correctly, the spear Voltvessel variant can instantly eliminate large bosses due to their large hitbox.

It may also be possible to land multiple hits or multiple ticks of damage rather than one due to the large span of the column of volt energy.

The bola version comes in handy in boss fights where you have to keep moving, as you can dispense the balls of volts and dash away, and if timed right, against bosses that dash towards you, you can easily get massive amounts of damage.

Pair this with the Crest of Architect and you almost become unstoppable, as you can easily replenish the number of Voltvessels you have and bind your injuries, making this a deadly pair.

This is also a great speedrun tool, as it can help clear arena battles with smaller, low-health enemies in a matter of seconds. Although the downside of this is that the unlock is very late-game.

Overall, this tool is a great addition to any play style or build, allowing you to explore different methods of taking up a fight, which you can unlock simply by exploring. And in a game like Silksong, who would not want to feel like they are the boss in the fight against the enemies
