Starting Location
You can begin this quest by accepting it at the Wishwall in Bone Bottom. Your mission is to hunt down a predator known as Volatile Flintbeetles at three different locations and bring back the gems that grow within their bellies. These Volatile Flintbeetles can be located in The Marrow

The first Flintbeetle can be found in the lower left chamber of The Marrow. This particular room is the very first area you can access when entering from the Bone Bottom.
After entering the chamber, climb up the ledges to reach the top of the room. You can spot these Flintbeetles clinging to the walls of the chamber, where they remain partially hidden. Only their bright orange gems are visible
Volatile Flintbeetles Location #2
The second Flintbeetle can be found in the upper right chamber of The Marrow.
Volatile Flintbeetles Location #3
