Welcome to the deep, dark waters of the Abyss. If you are here, you are likely hunting for one of the newest and most elusive materials added to the game in the February 2026 update: the Fish Bone. Whether you are looking to craft the new depth-defying gear or just want to flex your rare inventory, getting your hands on this item isn’t as straightforward as casting a line.

I’ve spent hours diving into the darkest trenches of the map, testing different methods, and verifying data from the community and official sources to bring you the most comprehensive guide available. Unlike standard fish drops, the Fish Bone requires a specific approach, the right equipment, and a bit of patience.

Below is a quick overview of everything we will cover to help you secure this drop.

Quick Overview: Fish Bone Acquisition

Method	Location	Difficulty	Drop Chance (Est.)	Best Tool
Skeletal Soulfish Hunt	The Bone Trench (Depth 4000m)	Hard	5% – 10%	Ancient Harpoon
Deep Sea Treasure Chests	Near the thermal vents	Medium	15%	None (Passive)
Trading/Merchant	Phantom Trader Outpost	Easy	N/A (Cost: Gold)	N/A

What is the Fish Bone in Abyss?

Before we dive into the how, let’s talk about the why. Introduced in the March 2026 content update, the Fish Bone is a Rare crafting material. It is not just a junk item; it is a critical component for crafting the Bone Crusher Harpoon and the Skull Diving Suit, two of the best gear additions for high-level players in this current meta.

Most players confuse this with standard “Old Bones” found on the seabed. The Fish Bone is distinct—it is a structural bone from a legendary fish species, often glowing faintly. Because it is a new release, the market value for this item is incredibly high, making it a prime target for players looking to make quick currency or upgrade their build.

Prerequisites: What You Need Before You Dive?

Don’t rush into the Abyss unprepared. The areas where the Fish Bone drops are treacherous, and without the right setup, you will become fish food before you get your drop. Here is what I recommend preparing before you start your hunt.

1. Adequate Oxygen and Depth Resistance

The Fish Bone drops in deep zones (Depth 3000m+). You need:

Rebreather Mk II: Ensures you don’t run out of oxygen quickly.
Depth Suit: Basic suits won’t cut it. You need pressure resistance above 3000m.

2. The Right Gear

You cannot catch the source of the Fish Bone with a basic rod.

Weapon: I highly recommend the Ancient Harpoon or the Deep Sea Rifle. The drop rate is tied to “harvesting” kills, so weak weapons make the grind harder.
Bait: Use Luminous Leeches. They attract the specific skeletal fish that drop this item.

3. Light Source

The Bone Trench is pitch black. Bring a Lantern Fish companion or a high-grade UV Light Stick. Not only does it help you see, but it also prevents ambush from predators in the dark.

Method 1: Hunting the Skeletal Soulfish (Best Method)

The most consistent way to get the Fish Bone is by hunting the Skeletal Soulfish, a new hostile mob added in the latest patch. This method yields the highest drop rate per hour if you are efficient.

Step 1: Locate the Bone Trench

You need to head to coordinates X: 450, Y: -1200 on your in-game map. This area is known as the Bone Trench. It is visually distinct because of the massive ribcage structures forming a canyon. Note: Be careful of the thermal vents here; they can damage you if you get too close.

Step 2: Equip Your Luminous Leeches

Once you arrive at the trench, equip your fishing rod/harpoon with the Luminous Leeches. Cast your line into the open water between the ribcages. The Skeletal Soulfish is attracted to this specific light spectrum.

Step 3: The Mini-Game

When you hook a Soulfish, the tension bar will be erratic—much harder than a Goliath Tuna.

Tip: Keep your tension in the green zone. If it hits red, the line snaps instantly.
Watch out: Reeling in a Soulfish aggros other nearby enemies. Be ready to fight.

Step 4: The Harvest

This is the crucial step many miss. Once you reel the Soulfish in, it doesn’t automatically go into your inventory as a Fish Bone. You must attack the fish on your boat/raft to “harvest” it.

Use your harpoon or knife to dismantle the fish.
Drop Rate: There is approximately a 1 in 10 chance (10%) that a Skeletal Soulfish will yield a Fish Bone upon harvesting. Sometimes you will get standard Fish Meat or Scales instead. Keep trying!

Method 2: Scavenging Deep Sea Treasure Chests

If combat isn’t your style, or if your gear isn’t top-tier yet, you can rely on RNG (Random Number Generation) via loot chests.

Where to Look

The Fish Bone has been confirmed to spawn inside Gilded Chests and Shadow Chests found in the deepest biomes. Specifically, check the wreckage sites around the Abyssal Cathedral.

The Strategy

Server Hop: This is a pro tip. Join a server, go to the Cathedral, loot all the chests. If there is no Fish Bone, leave the server and join a new one. The chests respawn in new servers.
Group Up: Bring a friend. The deep sea is dangerous. While one loots, the other watches out for the Leviathan class enemies that patrol the cathedral.

While this method requires less skill, the drop chance is lower (estimated around 2-5% per chest), so Method 1 is generally faster for dedicated farming.

Method 3: The Phantom Trader

For those with plenty of gold but little time, the developers added a shortcut, though it comes at a steep price.

Every 30 minutes, the Phantom Trader spawns at a random location in the safe shallows (Depth 0-500m). He sells rare goods from the deep.

Item: Fish Bone
Cost: 5,000 Gold
Stock: He usually only carries 1 or 2 at a time.

If you see the notification “A strange presence has been felt near the surface,” open your map immediately and look for his icon. It’s a quick buy if you have the cash saved up.

Advanced Tips and Common Mistakes

I’ve made plenty of mistakes while figuring this out, so you don’t have to. Here are some insider tips to maximize your efficiency in 2026.

Mistake to Avoid: Using Basic Bait

Do not use standard Worms or Insects. The Skeletal Soulfish will not bite. You are wasting your time. You must craft Luminous Leeches which require glowing algae found in caves. It’s an extra step, but it’s mandatory.

Pro Strategy: The “Lure and Farm” Technique

If you are playing on a PC, you can utilize a specific physics mechanic in the game.

Park your boat over a “Spawn Point” in the Bone Trench.
Use chum to attract multiple Soulfish.
Instead of reeling them in one by one, use an AOE (Area of Effect) weapon if available once they swarm the surface.
Note: This is risky but can yield 5-10 harvests in 2 minutes if executed perfectly.

Update Notes for February 2026

The latest patch adjusted the spawn rates of the Soulfish. They are now more active during the in-game “Night Cycle.” If you are fishing during the day in-game, your catch rate drops by 50%. I recommend adjusting your device time or waiting in-game until the sun goes down to start your grind.

What Can You Craft With Fish Bone?

Collecting the item is only half the battle. Here is why you need it:

Bone Crusher Harpoon: Deals +50% damage to skeletal creatures. Essential for the late-game boss, The Undying Kraken.
Skull Diving Suit: Provides immunity to the “Bleed” effect caused by coral and thorny fish in the deep trench.
Bone Elixir: A consumable that grants underwater breathing for 10 minutes. Great for extended diving sessions.

Frequently Asked Questions

Is the Fish Bone tradeable between players?

Yes, the Fish Bone is not a “soulbound” item. You can trade it with other players or sell it on the player market. Due to the difficulty of acquiring it, it holds high value right now.

What is the easiest way to get Fish Bone for beginners?

If you are under level 20, the Bone Trench is too dangerous. Your best bet is to save up gold and wait for the Phantom Trader. It takes time to save the 5,000 gold, but it guarantees the drop without risking your life.

Does the Fish Bone expire?

No, the Fish Bone is a permanent material item. It will not disappear from your inventory over time, unlike event-specific currency or bait.

Why can’t I catch the Skeletal Soulfish?

Double-check three things:

Are you at Depth 4000m or deeper?
Are you using Luminous Leeches?
Is it currently Night in the game cycle?
If you answered “No” to any of these, you won’t get a bite.

Can I store Fish Bones in my Vault?

Yes, you can store them in your personal vault or your guild chest if you are part of a group. This is useful if you are farming for a large crafting project like the Skull Diving Suit.

Conclusion

Getting the Fish Bone in Abyss during this March 2026 release window is one of the most rewarding grinds in the game right now. Whether you choose the adrenaline-pumping route of hunting Skeletal Soulfish in the Bone Trench or the strategic route of chasing the Phantom Trader, you now have the roadmap to success.

Remember, game updates are frequent. The drop rates or methods might be nerfed or buffed in future patches, so get your farming in now while the methods are fresh.

Good luck, diver, and watch out for the shadows below.
