Abyss Roblox Tube Guide: Fastest Route from Starter to Endgame

What to know

• Tube progression directly controls oxygen, speed, and fish storage, which define how deep and how long you can farm.
• The Puffer Fish Tube → Boat Tube → Oxy Tube → Lost Spirit → Ruined path is the most efficient upgrade route.
• Skipping certain mid-tier tubes saves tens of thousands of coins.
• Quest completion and mutated fish farming significantly accelerate late-game unlocks.

---

In Abyss, your tube determines everything from survival time underwater to how quickly you can grind high-value fish. If you upgrade randomly, you will waste currency and slow your progression. If you follow an optimized path, you can move smoothly from beginner waters to endgame zones while maximizing income and oxygen efficiency.

Below is a structured, beginner-to-endgame progression breakdown based on optimal spending and zone efficiency.

Quick overview of tube progression path in Abyss

Stage	Recommended Tube	Approx. Cost	Key Benefit	Skip?
Starter Island	Basic Tube (Free)	Free	Entry-level stats	No
Starter Island	Puffer Fish Tube	Low	Reliable oxygen boost	No
Ancient Sands	Shark Skin Tube	Mid	Minor stat boost	Yes
Ancient Sands	Boat Tube	Moderate	Major upgrade	No
Spirit Roots	Oxy Tube	~50,000	Massive oxygen jump	No
Late Game	Lost Spirit Tube	~168,000	Huge oxygen + storage	No
Endgame	Ruined Tube	High	Speed + oxygen focus	No
Endgame Alt	Bath Tube	High	Storage-heavy	Optional

Starter Island progression and early oxygen management

When you first spawn in Abyss, you begin with the Basic Tube, which provides minimal oxygen and limited storage. At this stage, your focus is not efficiency but survival and coin accumulation.

Your first real target should be the Puffer Fish Tube. This tube represents the first meaningful oxygen increase and allows you to dive deeper without constantly surfacing. The oxygen boost is strong enough to comfortably reach the next region, Ancient Sands, without excessive refilling.

What makes this upgrade important is its cost-to-performance ratio. You avoid wasting coins on incremental early upgrades and instead move directly toward a tube that meaningfully changes your dive duration.

Ancient Sands farming strategy and why to skip Shark Skin

Once you enter Ancient Sands, your income potential increases dramatically. However, this is where many players waste currency.

The Shark Skin Tube is available in this zone, but its stats are only slightly better than the Puffer Fish Tube. The price difference between Shark Skin and the next major upgrade is small relative to performance gain. Buying it delays your progress toward the Boat Tube and later Oxy Tube.

Instead, your focus should be on farming efficiently.

In Ancient Sands, two activities significantly increase your coin gain:

You can farm mutated fish, which sell for higher values than regular catches. These spawn periodically and should be prioritized when available. You should also complete Marcus’s quests, which provide structured objectives and bonus rewards that accelerate your savings.

Oxygen refilling becomes more strategic here. Crazy Jeff’s Cave provides a reliable refill spot, allowing you to extend farming sessions without returning to surface-level refill stations. Efficient route planning between fish clusters and refill points is key to maximizing earnings per dive.

The correct upgrade in this zone is the Boat Tube.

Abyss tube comparison table

Tube	Oxygen Capacity	Fish Storage	Speed	Best For
Basic	Very Low	Very Low	Low	Tutorial phase
Puffer Fish	Moderate	Low	Low	Early progression
Shark Skin	Slightly Higher	Slightly Higher	Low	Not recommended
Boat	High	Moderate	Moderate	Ancient Sands grind
Oxy	Very High	Moderate	Moderate	Mid-game breakthrough
Lost Spirit	Extremely High	High	Moderate	Late-game farming
Ruined	Very High	High	High	Endgame optimization
Bath	Very High	Very High	Moderate	Storage-focused builds

Why the Boat Tube is the turning point

The Boat Tube is your first major performance spike after Puffer Fish. It offers a substantial increase in oxygen capacity and smoother farming potential.

With the Boat Tube, you can stay submerged longer, target deeper fish, and complete quest objectives more efficiently. This upgrade also reduces dependency on constant oxygen refill loops.

By skipping Shark Skin and moving straight to Boat Tube, you preserve momentum and keep your coin trajectory aligned with mid-game progression.

Transitioning into Spirit Roots and saving for Oxy Tube

Spirit Roots marks the beginning of mid-to-late game progression. The zone is more demanding, oxygen drain feels harsher, and fish value rises.

Before upgrading here, you should aim to save approximately 50,000 coins. This milestone is critical because the Oxy Tube dramatically increases oxygen capacity.

The Oxy Tube is arguably the most impactful upgrade in the entire progression chain relative to its cost. It transforms previously stressful dives into manageable farming sessions. Areas that once required multiple refill stops can now be cleared in one sustained dive.

Spirit Roots also includes air pocket zones that function as oxygen refill checkpoints. Smart routing between these refill areas and high-value fish spawns lets you stack income quickly.

With Oxy Tube equipped, you gain:

• Long dive endurance
• Safer deep exploration
• Increased farming consistency

This stage prepares you for true late-game grinding.

Unlocking the Lost Spirit Tube through quest progression

Late-game progression requires more than coins. It demands mission completion.

In Spirit Roots, you encounter an NPC who provides missions that eventually unlock a previously blocked area. Completing this chain grants access to the Lost Spirit Tube, which costs approximately 168,000 coins.

This tube significantly increases both oxygen and fish storage capacity. The storage boost is especially important because longer dives become inefficient if you must surface early due to full inventory.

With Lost Spirit Tube equipped, your grinding speed accelerates because you spend less time traveling to sell and more time farming high-value fish.

This is the stage where your income curve steepens noticeably.

Ruined Tube vs Bath Tube in endgame

The final major progression milestone involves the Ruined Tube and the alternative Bath Tube.

To unlock Ruined Tube, you must complete the Lost Captain quest chain. This questline is time-intensive but mandatory for access.

The Ruined Tube emphasizes:

• Higher movement speed
• Strong oxygen capacity
• Efficient deep-zone farming

Meanwhile, the Bath Tube leans heavily toward fish storage. If you own the “sell anywhere” game pass, storage becomes less critical because you can offload inventory without returning to surface shops. In that case, Ruined Tube is typically superior.

If you do not have that game pass, Bath Tube may align better with your farming style because extended storage reduces surface trips.

Your choice depends on whether your priority is movement efficiency and oxygen dominance or maximum inventory uptime.

How to progress from beginner to endgame efficiently

Step 1

Start with the Basic Tube and immediately focus on farming enough coins to purchase the Puffer Fish Tube. Avoid spending on unnecessary minor upgrades.

Step 2

Enter Ancient Sands using Puffer Fish. Farm mutated fish aggressively and complete Marcus’s quests to build capital efficiently.

Step 3

Skip Shark Skin entirely and save directly for the Boat Tube. Purchase Boat Tube as your primary Ancient Sands upgrade.

Step 4

Accumulate approximately 50,000 coins before transitioning into Spirit Roots. Prioritize Oxy Tube as your next purchase.

Step 5

Complete Spirit Roots mission chains to unlock the Lost Spirit area. Continue farming high-value fish to reach 168,000 coins.

Step 6

Purchase Lost Spirit Tube and accelerate late-game grinding with extended oxygen and storage.

Step 7

Complete Lost Captain quest to unlock Ruined Tube. Decide between Ruined or Bath based on your selling method and farming style.

Optimal progression summary for maximizing income

Efficient tube progression is less about buying every upgrade and more about buying the right upgrades. The biggest mistake players make is investing in marginal improvements that delay transformative upgrades.

If you prioritize:

• Puffer Fish
• Boat
• Oxy
• Lost Spirit
• Ruined

you maintain consistent scaling in oxygen, storage, and farming efficiency without burning unnecessary coins.

The result is a smooth climb from shallow beginner waters to the deepest endgame zones in Abyss Roblox.

By skipping inefficient mid-tier purchases and focusing on milestone tubes like Boat, Oxy, and Lost Spirit, you set yourself up for sustainable endgame success.

Master the upgrade path, complete the right quests, and your journey from Starter Island to Ruined tier becomes not just faster, but significantly more rewarding.
