What to know

- Preparation with the Spirit Tube and a strong gun saves hours of grinding.
- Completing the quest also unlocks extra rewards behind the barrier.
If you’re aiming to secure the Lost Spirit Gun in Abyss, you’ll need patience, strong preparation, and a lot of fishing. This weapon is locked behind a multi-stage barrier quest that demands specific fish, mutated variants, and rare materials. The grind can feel intense, but if you prepare correctly and understand the spawn patterns, you can significantly speed up the process.
Below is a quick glance at what you’re dealing with before diving into the full walkthrough.
Quick overview of the Lost Spirit Gun unlock process
| Requirement Type | Details |
|---|---|
| Main Objective | Complete the three-part Barrier Quest |
| Core Activity | Fishing rare and mutated fish |
| Recommended Tools | Spirit Tube, Strong Gun, Radar |
| Rare Materials | Rooted Geodes, Moss |
| Final Reward | Lost Spirit Gun + Lost Spirit Tube |
| Bonus Rewards | Hidden chest, hidden duck, Victor Quest rewards |
Why preparation matters before starting the barrier quest
Before you even accept the Barrier Quest, you should strongly consider securing the Spirit Tube and equipping a high-damage gun. The Spirit Tube allows deeper fishing access, which is critical for catching high-tier fish efficiently. Using something like the Zipline Tube may seem convenient, but its limited depth makes it inefficient for farming the required species.
A strong gun helps in two ways. First, it speeds up encounters with aggressive creatures while exploring caves. Second, it allows you to manage dangerous zones without repeated deaths, which would slow down your farming rhythm.
You’ll also want to use a radar. Many required fish have similar silhouettes, and radar dramatically reduces wasted time catching the wrong species.
Barrier quest stage one requirements explained
The first stage focuses on gathering a mixture of standard and mutated fish along with geological materials.
Stage one item requirements
| Item | Quantity Required | Notes |
|---|---|---|
| Napoleon | 3 | Medium-large fish |
| Jellyfish | 6 | Common but scattered |
| Pacific Fanfish | 8 | Recognizable fan-shaped fins |
| Spirit Mutated Fish | 6 | Glowing spirit variant |
| Rooted Geode | 2 | Found during fishing |
| Moss | 3 | Environmental material |
The Spirit Mutated Fish glow faintly and are easier to identify when using radar. While fishing, you may notice treasure chests spawning inconsistently. If a chest does not appear quickly, you can cancel and retry fishing to speed up acquisition attempts. This method saves time across dozens of repetitions.
Rooted Geodes are not fish but are obtained during fishing sessions. They are rarer than standard catches and require persistence.
Barrier quest stage two requirements explained
Stage two increases the difficulty by raising quantities and introducing another mutated variant.
Stage two item requirements
| Item | Quantity Required | Notes |
|---|---|---|
| Sunfish | 5 | Flat, pancake-shaped body |
| Napoleon | 8 | Repeat requirement |
| Jellyfish | 10 | Higher quantity |
| Fairy Mutated Fish | 6 | Bright, glowy mutation |
| Rooted Geode | 5 | Increased rarity pressure |
| Moss | 4 | Gather while exploring |
The Sunfish are visually easy to identify due to their flat circular shape. The Fairy Mutated Fish stand out because of their bright glow. These mutations spawn less frequently than normal fish, so expect some repetition.
By this point, your efficiency heavily depends on your preparation. If you skipped upgrading gear earlier, you’ll feel the slowdown here.
Final barrier quest stage and the narwhal requirement
The third and final stage dramatically increases the total fish required and introduces the Narwhal.
Stage three item requirements
| Item | Quantity Required | Notes |
|---|---|---|
| Narwhal | 6 | Frequently spawns in caves |
| Sandfish | 8 | Found in sandy regions |
| Napoleon | 12 | High repetition |
| Fairy Mutated Fish | 8 | Rare variant |
| Spirit Mutated Fish | 12 | Heavy grind requirement |
| Rooted Geode | 7 | Rare material |
| Moss | 5 | Environmental |
The Narwhal is the only new species in this stage. It spawns frequently in caves, making cave exploration the most efficient farming method. Focus your route inside cave systems rather than open waters to maximize Narwhal encounters.
The high number of Spirit Mutated Fish in this stage is what makes the grind feel longest. Efficient use of radar and deep fishing spots significantly reduces wasted attempts.
How to complete the barrier quest and unlock the weapon
- Accept the Barrier Quest and confirm all three stages are visible in your quest tracker.
- Equip the Spirit Tube and your strongest available gun before starting serious farming.
- Farm stage one fish and materials, prioritizing radar-assisted fishing to reduce misidentification.
- Turn in stage one and immediately begin stage two farming, focusing on Sunfish regions and glowing mutations.
- Move into cave systems during stage three to farm Narwhals efficiently while collecting remaining mutated fish.
- After submitting all final requirements, trigger the completion event. A cutscene will play, showing the barrier being destroyed.
- Enter the newly opened area to collect the Lost Spirit Gun and the Lost Spirit Tube.
What happens after the barrier is destroyed
Once the barrier collapses, you gain access to the hidden area. Inside, you’ll find the Lost Spirit Gun, which features enhanced spirit-based combat capability. You also receive the matching tube upgrade.
Behind the barrier, there is also a hidden duck collectible and a bonus chest. These are easy to miss if you rush out immediately after grabbing the weapon.
It’s also strongly recommended to accept the Victor Quest at this point. Completing it rewards you with money and Ancient Keys, adding long-term value beyond just unlocking the gun.
Post-barrier rewards overview
| Reward | Description |
|---|---|
| Lost Spirit Gun | High-tier spirit-based firearm |
| Lost Spirit Tube | Tube upgrade |
| Hidden Chest | Bonus loot |
| Hidden Duck | Collectible |
| Victor Quest Rewards | Money and Ancient Keys |
Why the Lost Spirit Gun is worth the grind
The Lost Spirit Gun stands out because of its spirit-infused damage profile, making it highly effective in mid-to-late game combat. While the farming requirement is intense, the weapon provides noticeable combat efficiency once obtained.
If you approach the Barrier Quest methodically and use optimized fishing routes, what initially feels overwhelming becomes a structured grind.
Getting the Lost Spirit Gun in Abyss made simple
Unlocking the Lost Spirit Gun in Abyss is ultimately about preparation and efficiency. Equip the right tools, farm smart using radar and cave routes, and complete all three Barrier Quest stages. Once the barrier falls, the reward is immediate and absolutely worth the effort.
