What to know

- Ancient Sands is your first major power spike area.
- Spirit Roots unlocks the biggest damage upgrades through quests.
- Endgame harpoons require quest chains and hidden unlock conditions.
In Abyss (Roblox), harpoon progression determines how quickly you can farm high-value fish and bosses. If you buy weapons out of order, you will burn coins on upgrades that quickly become obsolete. The current optimal path focuses on damage efficiency, cooldown speed, and quest-based unlocks to minimize grinding while maximizing profit.
Below is a quick-glance overview before diving into the full step-by-step progression.
All Abyss Harpoons – early to late game progression
| Stage | Harpoon | Cost | Damage | Requirement | Recommendation |
|---|---|---|---|---|---|
| Early Game | Basic Harpoons | Low | Low | Starter Island | Buy for progression only |
| Early Game | Advanced Harpoon Gun | Moderate | Strong early damage | Starter Shop | Essential purchase |
| Early Game | Air Rifle | Moderate | Low scaling | Starter Shop | Skip |
| Ancient Sands | Crossbow Harpoon | 5,000 | Strong jump | Hidden Cave | Must buy |
| Ancient Sands | Ruined Gun | 18,500 | High | Crazy Jeff Shop | Major upgrade |
| Spirit Roots | Mag Root Gun | 47,000 | Massive spike | Spirit Roots access | Core mid-game |
| Spirit Roots | Lost Spirit Gun | 150,000 | Very high | NPC quest chains | Best value late-mid |
| Endgame | Ruined Gun (Angler Cave) | 245,000 | 350 | Lost Captain quest | Strong endgame |
| Endgame | Plunger Gun | 321,000 | 420 | 15 Rubber Ducks | Final tier |
Starting smart on the starter island
When you first begin, you’ll naturally need to purchase the early harpoons one by one to unlock stronger options. These starter weapons are inexpensive and act primarily as progression gates rather than long-term investments.
Your key goal here is to reach the Advanced Harpoon Gun as quickly as possible. This weapon provides a noticeable jump in damage output and allows you to efficiently kill stronger fish without extended cooldown frustration.
You should intentionally skip the Air Rifle. While it may look like a natural upgrade, its performance scaling does not justify the cost compared to what you unlock soon after. Buying it only delays your ability to move into Ancient Sands progression.
Moving into Ancient Sands for your first major upgrade
Once you secure the Advanced Harpoon Gun, your next destination is Ancient Sands. Before heading there, you should have the Puffer Fish Tube, as oxygen management becomes more important in deeper waters.
Ancient Sands introduces structured quest progression that funds your first major weapon spike. Completing the Diver Quest up to stage five, along with Mr. Black’s and Verilia’s quest lines, provides roughly 5,000 coins, which you will need immediately.
Inside a hidden cave near the large fossil skeleton landmark, you’ll find a crossbow-style harpoon.
Ancient Sands harpoon comparison
| Harpoon | Cost | Strength | Why It Matters |
|---|---|---|---|
| Crossbow Harpoon | 5,000 | Large damage boost | Significant cooldown improvement |
| Ruined Gun (Crazy Jeff) | 18,500 | High | Carries you into Spirit Roots |
The Crossbow Harpoon is your first serious power spike. It dramatically improves both damage and cooldown pacing, allowing you to farm higher-value targets faster.
Inside the same cave, you’ll encounter Crazy Jeff’s Shop, where the Ruined Gun is sold for 18,500 coins. This weapon requires grinding but is worth every coin. It prepares you for deeper regions and tougher fish.
Preparing properly before entering Spirit Roots
Before progressing into Spirit Roots, you should complete Marcus’ quest, the Suspicious Fisher quest, and Grumpy Hung’s quest while farming high-selling fish such as mutated fish, sharks, and hammerheads. Efficient farming here dramatically reduces your grind later.
You must also upgrade your tube at least to the Zipline tier. Spirit Roots has deeper dive zones, and poor oxygen capacity will slow your farming efficiency significantly.
Inside Spirit Roots, you’ll find a large underwater door that functions as an oxygen refill point. Learning its location saves enormous downtime.
Securing the Mag Root Gun
The first major Spirit Roots weapon is the Mag Root Gun, priced at 47,000 coins. This gun delivers a massive damage spike compared to the Ancient Sands Ruined Gun.
Spirit Roots mid-game progression
| Harpoon | Cost | Power Tier | Priority |
|---|---|---|---|
| Mag Root Gun | 47,000 | High | Essential |
| Morith’s Gun | — | Moderate | Skip |
| Lost Spirit Gun | 150,000 | Very High | Critical purchase |
You should avoid purchasing Morith’s Gun, as it does not scale efficiently relative to its cost. It slows overall progression and delays your access to the Lost Spirit Gun.
Unlocking the Lost Spirit Gun
The Lost Spirit Gun, costing 150,000 coins, is one of the strongest value-per-coin weapons in the game. However, it requires completing three sets of NPC quest chains inside Spirit Roots. Once finished, a large sealed door deeper in the region unlocks.
After unlocking access, the Lost Spirit Gun becomes available for purchase. At this stage, you’ll notice a dramatic farming speed increase, especially against high-health targets.
Transitioning into endgame harpoons
Once you reach late-game progression, you’ll encounter the Lost Captain quest. The Lost Captain can be found near a shipwreck. Completing his quest unlocks access to the Angler Cave.
Inside Angler Cave, you can purchase another Ruined Gun variant for 245,000 coins. This weapon delivers 350 damage and is a significant late-game option.
Endgame weapon comparison
| Harpoon | Cost | Damage | Unlock Method |
|---|---|---|---|
| Ruined Gun (Angler Cave) | 245,000 | 350 | Lost Captain Quest |
| Plunger Gun | 321,000 | 420 | 15 Rubber Ducks + Hidden Door |
The final discussed weapon is the Plunger Gun, which deals 420 damage. To unlock it, you must locate 15 scattered rubber ducks hidden across the map. After collecting them, a hidden door beneath a large rock becomes accessible, allowing you to purchase the weapon for 321,000 coins.
This is currently considered the highest-tier harpoon in the game’s present state.
Why following this order saves thousands of coins
Harpoon progression in Abyss is not linear in efficiency. Some guns exist mainly as optional side upgrades that look attractive but slow you down long term. Skipping the Air Rifle and Morith’s Gun prevents wasted spending and keeps your funds directed toward major damage spikes.
Each recommended upgrade aligns with either a quest milestone or a major region transition. If you follow this exact order, your damage scaling will match the fish difficulty curve, preventing unnecessary grind walls.
Best progression path summary
Harpoon progression in Abyss Roblox rewards strategic planning far more than impulsive upgrading. If you follow the optimized path outlined above, you will consistently outpace players who buy every weapon they see.
If you want the cleanest and fastest route, your path should look like this in practice: Starter Harpoons → Advanced Harpoon Gun → Crossbow Harpoon → Ruined Gun (Ancient Sands) → Mag Root Gun → Lost Spirit Gun → Angler Cave Ruined Gun → Plunger Gun.
This sequence ensures that every coin you spend results in meaningful power growth.
Stick to the high-impact upgrades, complete quest chains efficiently, and prioritize oxygen upgrades alongside weapon progression. If you do that, you will reach the Plunger Gun faster and with far less wasted grind.
