Key NPCs and Services
The Kraken stands at the center of the safe dome, serving as your primary quest giver during early progression. This massive creature provides starter quests that teach fundamental mechanics while rewarding you with currency for fish sales. Complete these quests systematically to unlock better equipment and access new areas.
Scientist NPC manages the crucial Teleporter device located next to his position. To activate fast travel, you must complete his quest by finding three scattered materials across Forgotten Deep. Once activated, this teleporter becomes invaluable for quick biome transitions later in the game.
Virelia, the powerful mage positioned behind her purple-glowing cauldron, specializes in geode cracking. As you catch fish and collect geodes, bring them to Virelia to extract valuable artifacts and progression items. She also offers specific quests related to artifact collection that reward substantial Star Shards.
David’s Tube Shop represents your primary equipment upgrade source. Located to the right of Virelia, David sells various tubes with increasing depth capacities. The Pufferfish Tube ($2850) is your first major purchase, enabling access to Ancient Sands at 180m depth.
Richard’s Bestiary tracks your fish collection progress and rewards Star Shards for each new species discovered. These valuable shards are essential for race rerolls, making Richard crucial for character optimization. His shop also sells the Fish Radar ($450) for identifying nearby fish mutations.
Henry and the Crab operate the harpoon shop next to Richard. Henry sells various guns for catching different fish types, while the Crab offers a secret quest when you bring him the hidden scroll. This questline leads to exclusive rewards and progression items.
Billy’s Storage provides essential inventory management solutions. Found leaning against a blue container near Mr. Black, Billy offers portable stash access across all three biomes, with upgrade options for increased storage capacity.
Mr. Black introduces the fish mutation system and sells oxygen pods and speed potions from his shop. His inventory refreshes every 44 seconds, offering time-limited opportunities for crucial supplies.
Progression Essentials
Master Forgotten Deep by completing Kraken’s quests, purchasing the Pufferfish Tube, and activating the Scientist’s teleporter. Focus on catching diverse fish species for Richard’s bestiary to accumulate Star Shards for race optimization. This foundation prepares you for Ancient Sands exploration.
Ancient Sands Biome: The Mid-Game Hub
Ancient Sands represents your first major progression milestone, accessible after purchasing the Pufferfish Tube. This mid-game biome (180-275m depth) features a distinctive sand waterfall landmark and contains 6 important NPCs offering advanced gear and lucrative quest opportunities.
Landmark Navigation
The sand waterfall serves as Ancient Sands’ most prominent landmark. Most important locations and NPCs are either underneath this waterfall or within the surrounding cave systems. This area consistently spawns mid-game fish, making it ideal for grinding coins and experience.
Essential NPC Contacts
Marcus sits near the creature skeleton beneath the sand waterfall, offering quests and selling important tube upgrades. His location marks the central point of Ancient Sands’ activity.
Crazy Jeff resides in a nearby cave and represents the most critical NPC in this biome. Jeff sells the game map – an essential navigation tool that makes finding biomes and NPCs significantly easier. His cave also contains oxygen replenishment pods that can save your life during deep dives.
Additional NPCs include Grumpy Hank and the Suspicious Fisher, both providing side quests and valuable items that aid progression.
Strategic Farming Tips
Ancient Sands offers the best mid-game fish farming opportunities. Focus on catching higher-value species here to accumulate coins for expensive endgame equipment. The biome’s depth range (120-300m) provides access to profitable fish while remaining accessible with mid-tier tubes.
Ocean Biome: The Deep Water Challenge
Located far east from the Kraken in Forgotten Deep, the Ocean biome spans depths of 280-300 meters and introduces more challenging navigation and valuable rewards.
Major Discoveries
The Ocean biome’s most striking feature is the submarine where the Diver NPC sits atop it. This NPC provides chest delivery quests that eventually unlock access to Spirit Roots biome. Further exploration reveals a wrecked ship housing the Lost Captain NPC.
Deep within the Ocean’s cave systems lies Morveth’s Cave, accessible through underwater passages. Morveth provides significant rewards, including your first Ruby Rune – a crucial item for late-game progression.
Quest Integration
The Diver’s quest chain represents the primary pathway to accessing Spirit Roots. Focus on completing these delivery missions efficiently, as they’re essential for story progression. The Lost Captain’s quests, while challenging, unlock the Angler’s Cave – a valuable endgame area.
Navigation Challenges
Ocean biome navigation requires careful oxygen management. The 280-300m depth range pushes most mid-tier tubes to their limits. Consider upgrading to the Rukiry Tube before extended exploration here, and always note the location of oxygen replenishment points.
Spirit Roots Biome: The Endgame Frontier
Spirit Roots represents Abyss’s primary endgame biome, requiring tubes capable of reaching 375-450 meters depth. Access is granted only after completing the Diver’s quest chain, specifically the chest delivery missions.
Access Requirements
Progression to Spirit Roots demands:
- Completion of Diver’s delivery questline
- Tube capable of 375m+ depth (Oxy Tube or Zepline Tube recommended)
- Teleporter access for efficient travel
Key NPCs and Rewards
Isolde and Lumi serve as the primary NPCs in Spirit Roots. Completing their quests opens the water barrier protecting the biome’s most valuable content.
Behind this barrier, Victor provides the Lost Spirit Tube and Lost Spirit Gun – among the best equipment in the game. Golem offers substantial rewards for quest completion, while King Cat grants the prestigious King’s Fortune artifact.
Endgame Strategy
Spirit Roots contains the game’s most valuable fish species and artifacts. Focus on completing Isolde and Lumi’s quests quickly to access the water barrier. The rewards behind this barrier significantly boost your fishing capabilities and income potential.

Frequently Asked Questions
How do I unlock the map in Abyss?
Purchase the map from Crazy Jeff in Ancient Sands biome. You’ll need to reach Ancient Sands first (requires Pufferfish Tube for 180m depth), then find Crazy Jeff in his cave near the sand waterfall. The map costs 2,500 coins and makes navigation significantly easier.
What’s the best tube for each biome?
- Forgotten Deep: Normal Tube → Pufferfish Tube
- Ancient Sands: Boat Tube (essential for full exploration)
- Ocean: Rukiry Tube recommended
- Spirit Roots: Oxy Tube or Zepline Tube required
- Endgame: Bath Tube (from Bob’s Secret Room)
How do I access Spirit Roots biome?
Complete the Diver’s entire quest chain, specifically all chest delivery missions. The Diver is located on the submarine in Ocean biome (280-300m deep, far east from Kraken). After completion, you can warp to Spirit Roots using the teleporter.
Where can I find the King Anglerfish?
The King Anglerfish is located in Angler’s Cave, which unlocks after completing the Lost Captain’s quest chain and reaching level 35. The cave entrance is across from the Lost Captain in Ocean biome. Bring your best equipment – this is one of the toughest catches in the game.
What are Star Shards used for?
Star Shards are primarily used for race rerolls at the race reroll NPC. You earn Star Shards from Richard for discovering new fish species, completing quests, and certain achievements. Save them for rerolling to better races like Kraken or Sea Angel.
How do I get to Bob’s Secret Duck Room?
Find all 15 special ducks hidden across all biomes. They’re scattered throughout Forgotten Deep, Ancient Sands, Spirit Roots, and other areas. After collecting all ducks, go to the area behind the Tubes Shop in Forgotten Deep Dome and drive straight to find the secret entrance.
What’s the fastest way to earn money in Abyss?
Ancient Sands biome offers the best mid-game money farming with its abundant fish population. For endgame players, Spirit Roots provides the most valuable fish species. Focus on catching higher rarity fish with good mutations, and always use the Radar to identify valuable catches.
Should I skip any equipment upgrades?
Yes, experienced players recommend skipping the Fire Tube and Advanced Gun to save money. The Fire Tube has poor oxygen efficiency, and the Advanced Gun is quickly outclassed by better options. Save your coins for more impactful upgrades like the Boat Tube and Crossbow Gun.
