While pushing through Act 3 of Hollow Knight: Silksong, I noticed a new Hunt-type wish pinned to the Bellhart Wish Board. The citizens of Bellhart were clearly unsettled—they kept looking over their shoulders at dark, pulsing growths that had begun appearing in the surrounding areas. Their wish was simple: find someone brave enough to remove the Void Masses permanently. That request turned out to be the Dark Hearts quest. It did not take long to trigger, but tracking down enough Void Masses made me climb through almost every corner of Pharloom.

The trigger itself is straightforward once you have reached Act 3. I approached the Bellhart Wish Board and grabbed the wish. From that moment, Hornet's objective was to destroy 12 Void Masses. The reward promised for clearing the danger was a Mask Fragment, which is always useful for survivability. What surprised me was how many Void Masses actually exist—there are more than 40 scattered across Pharloom, but only 12 are required for the quest. That gave me plenty of freedom to pick a route close to Bellhart and avoid some of the more dangerous detours.

I started my search right outside Bellhart. From the hub, I headed right and took the elevator upward. After running left and climbing a few rocky ledges, I reached Shellwood. Under one of the wooden platforms I found my first Void Mass. The growth was dark, sticky, and seemed to cling to the surface like tar. A quick strike removed it.

I continued left and glided down beneath a cliff edge to find a second Void Mass. Staying on lower ground, I entered a larger chamber. Near the top of that area, next to a room entrance, a third Void Mass was stuck to the side of the wall. Venturing through a lower door to the left brought me close to the bench near Bone Bottom. In that horizontal room, another Void Mass clung to the ceiling, forcing me to jump and strike upward.

From Shellwood I made my way toward The Marrow. I also used the Needle to summon the baby Bell Beasts and returned to the Bellway, which allowed me to teleport closer to my next targets. Heading left from the Bellway and then down revealed a Void Mass tucked in a corner under a platform on the right. Gliding down to the bottom of a vertical room, I looked to the upper left corner and used the platforms to reach another one. Climbing to the top of that same vertical room, I went right and found a Void Mass on the roof near a red bulb. Further right, I flew past a bench—resting there helped because the enemies were starting to pile up—and found a Void Mass on the upper part of the area.

Deep Docks became the next major stop. I kept moving in the same direction and climbed the second vertical room. At the end, a Void Mass waited. Heading higher and turning left, I saw another Void Mass stuck to the side of a platform near the lava. That one was tricky because enemies guarded the area. I cleared them first and then used a plunge attack to scrape the growth off cleanly.

I briefly considered heading into Hunter's March. There is a Void Mass on the roof above two enemies not far from the entrance, but after checking my count I decided to skip it. If you want a safer route or need an extra one without going too far into Far Fields, Hunter's March is a reasonable option. However, I preferred to push forward.

Returning to Deep Docks, I went right into Far Fields. I climbed higher and moved into the next area, where a Void Mass was stuck to the top and surrounded by enemies. Defeating them before removing the mass made the task less frantic. Then I went back to the previous room, glided down to the lower section, and ran right. There, under one of the platforms near the lava, I found the final Void Mass I needed for my count.

By the time I destroyed twelve, I had explored a good chunk of Pharloom. The route I followed was not the only option, and I know I left many Void Masses untouched in more distant areas. That is one of the best parts of the Dark Hearts quest: you can mix and match based on your preferred path, your combat comfort, and whether you want to detour into optional regions.

Returning to Bellhart felt satisfying. I spoke with the quest giver, turned in the removed Void Masses, and completed the Dark Hearts quest. The reward was exactly what the board had promised—a Mask Fragment. For any player in Act 3, I would recommend picking up this wish early and keeping an eye out for the dark growths as you travel. Since only twelve are needed out of more than forty, the quest is manageable even if you skip the more hostile locations.

Quick trigger checklist:

• Advance to Act 3.

• Visit the Bellhart Wish Board.

• Accept the Hunt-type wish called Dark Hearts.

• Destroy 12 Void Masses anywhere in Pharloom.

• Return to Bellhart and turn them in for a Mask Fragment.

A few tips that helped me:

• Use plunge attacks when a Void Mass is attached to a platform or floor.

• Clear nearby enemies before trying to remove a growth.

• Rest at benches before enemy-heavy rooms.

• Watch ceilings, corners, and the undersides of platforms, because the black growths blend into shadows.

Once you've cleared your board and collected that Mask Fragment, it's natural to start thinking about the next adventure. Many players I know like to keep a rotating backlog of games so they can jump straight from one quest to another. Hunting for good deals is part of that habit, and I've found it pays to compare prices before picking up a new title.

Whether you're chasing another Metroidvania with similar exploration or want to switch genres entirely, grabbing a game at a solid discount makes the next adventure even easier to start. Happy hunting, and may your benches always be nearby.
