By 2026, the quest board in Bone Bottom had become a familiar sight to the hunter who moved through Hollow Knight: Silksong’s caverns with a needle in hand and a map in mind. The board was a patient spider, spinning new tasks onto its web as each region fell quiet. One task, Volatile Flintbeetles, asked for three shelled nuisances in The Marrow to be found and defeated. The request looked simple. The hunt was not.

A Board Full of Whispers

The hunter had cleared enough of the world for Bone Bottom to offer more work, and the Volatile Flintbeetles request sat among the newer notices. It demanded three Flintbeetles, each hidden in The Marrow. The game offered hints, but the hints were shy things—placed in likely rooms, half-swallowed by shadow, easy to pass without noticing. Tracking the beetles through the trail of clues made the work smoother. Ignoring the clues turned the hunt into a slow combing of stone and silk.

The trail of hints unspooled like a lantern-fish’s lure through black water—bright enough to follow, strange enough to make the hunter doubt the dark. Each beetle had its own pocket of The Marrow, and each demanded a different approach.

First Flintbeetle: The Ceiling Above the Bone Bottom Exit

The first hint waited by the resting bench near the Bone Bottom exit from The Marrow. From that bench, the path ran west and then upward toward the Mosshome exit. The hunter stopped before the path ended, on the top of the larger area just outside Bone Bottom and below Mosshome. A platform crowned that space, and the Flintbeetle clung to the ceiling above it. A jump and a strike woke the creature. The fight was brief but sharp, and the first Flintgem dropped once the shell cracked.

Second Flintbeetle: The Vertical Shaft

The second hint sat in the next area to the right of that starting bench. Again the path climbed. The vertical shaft in the middle of The Marrow breathed like a sleeping lung, its enemies rising and falling with each step. The beetle waited at the very top. The climb was the real trial: the final stretch held six or seven enemies, many of them flying bugs that tried to pin the hunter against the shaft walls. Patience and clean needle-work carried the hunter through. The second Flintbeetle fell, and the second Flintgem was claimed.

Third Flintbeetle: The Eastern Bench

The final hint was the easiest of the batch to find quickly. It waited at the furthest bench to the east, right under the Hunter’s March exit. The hunter took the path straight up and then turned into the upper room to the left. There, the last Flintbeetle waited. The Flintbeetles were small, hot embers wrapped in shell—not towering monsters, but dangerous when cornered. The third and final Flintgem was collected after a short, explosive scuffle.

How to Fight the Flintbeetles

The shelled bugs were not the biggest threat in The Marrow, but they could catch an unprepared hunter off guard. Their moveset was small, yet each move left fire in the air.

😤 The Charge Forward and Bounce attacks rewarded calm feet. The Explosive Flint attack rewarded a steady needle. The Explosive Death rewarded restraint—the hunter who rushed in too early met a face full of stones.

The Reward and the Return

With all three Flintgems in hand, the hunter returned to Bone Bottom. Interacting with the quest board completed the Volatile Flintbeetles task and granted the Memory Locket, an item used to unlock portions of Crests for combat. The board’s web had given up its prize. The hunter moved on, needle ready, with three fewer embers burning in The Marrow.
