Fisch Mysterious Marrow Quest Guide – How to Get the Fang, Spine, and Skull!

The Drylands update in Fisch introduces the Mysterious Marrow Quest, a short questline that requires players to collect three special items before they can progress. While the quest itself isn’t particularly difficult, it can be confusing if you don’t know where each item comes from. In this guide, we’ll show you how to get the Mysterious Skull, Mysterious Spine, and Mysterious Fang so you can complete the Mysterious Marrow Quest without wasting time.

Mysterious Marrow Quest Requirements

To finish the quest, you’ll need to collect all three of the following items:

  • Mysterious Skull
  • Mysterious Spine
  • Mysterious Fang

Each item is obtained in a different way, so you’ll need to visit multiple locations before returning to complete the quest.

How to Get the Mysterious Skull

The Mysterious Skull is the easiest item to obtain. Instead of completing a challenge or defeating an enemy, you can simply purchase it from the same Drylands merchant that previously sold the Undefined Magnetite Core during the earlier questline. The Skull costs:

  • 150,000 Coins

If you’ve already completed the previous Drylands objectives, you should already know where this merchant is located, making this the quickest item to collect.

How to Get the Mysterious Spine

The Mysterious Spine is actually rewarded much earlier than many players realize.

  • After helping the Drylands NPC by delivering the Undefined Magnetite Core.
  • the NPC gives you the Mysterious Spine as part of the quest progression.
  • Because of this, many players already have the item in their inventory without noticing.

Before searching around the Drylands, check your inventory first to see if you’ve already received the Spine.

How to Get the Mysterious Fang

The final item is the Mysterious Fang, and this one requires traveling outside the Drylands. Head over to Ancient Isle, where you’ll need to find a specific NPC connected to the quest. Once you speak with the NPC:

  1. Start the conversation.
  2. Answer all of the NPC’s questions correctly.
  3. Complete the dialogue.
  4. Receive the Mysterious Fang as your reward.

Unlike the other two items, this reward depends on interacting with the correct NPC rather than purchasing or collecting an object.

How to Complete the Mysterious Marrow Quest

Once you’ve collected every required item, simply return to continue the quest. Your inventory should contain:

  • Mysterious Skull
  • Mysterious Spine
  • Mysterious Fang

With all three items gathered, you’ll be able to complete the Mysterious Marrow Quest and continue progressing through the Drylands content.


The Mysterious Marrow Quest is more straightforward than it first appears once you know where each item is located. Purchase the Mysterious Skull from the Drylands merchant, claim the Mysterious Spine from the NPC after delivering the Undefined Magnetite Core, and visit Ancient Isle to obtain the Mysterious Fang by answering the NPC’s questions correctly. With all three items in hand, you’ll be ready to complete the quest and continue exploring everything the Drylands update has to offer.
