Forgotten Deep: Your Starting Paradise

The Forgotten Deep serves as your introduction to the world of Abyss. This biome spans from 0-100 meters depth and is where you’ll spawn upon entering the game. As the main hub area, it’s packed with essential NPCs who will guide your early progression.

Essential NPCs in Forgotten Deep

Kraken – Your primary quest giver and fish buyer. Kraken provides the main story quests (1-8+) that guide your progression through the game. He’ll reward you with the Normal Tube and Advanced Gun early on.

Scientist – Crucial for unlocking fast travel. Complete his teleporter quest early to gain access to the teleporter system, which will save you countless hours of swimming between biomes.

Virelia – Your go-to NPC for geode cracking. She’ll help you extract valuable artifacts from the geodes you find while fishing.

David – The tube merchant. Start with the Normal Tube from Kraken, then upgrade to the Pufferfish Tube ($4,500) to reach Ancient Sands.

Henry – Sells various harpoon guns. While the Advanced Gun is decent, I recommend saving money for better options in later biomes.

Billy – Operates the fish bank. Store your valuable catches here to avoid losing them if you die during deep dives.

Mr. Black – Introduces you to fish mutations, which can significantly increase the value of your catches.

Richard – Tracks your bestiary progress and sells the essential Radar for $250. This tool shows fish stats, mutations, HP, and rarity – absolutely crucial for efficient fishing.

Pro Tips for Forgotten Deep

Skip the Fire Tube and Air Rifle Gun – These are tempting upgrades but waste money that could be better spent on the Pufferfish Tube
Buy the Radar immediately – At $250, it’s the best investment you can make early game
Complete Virelia and Mr. Black’s quests alongside Kraken’s – Their objectives overlap, saving you time
Store valuable fish in Billy’s Bank before attempting risky deep dives

Ancient Sands: The Mid-Game Powerhouse

Located at 120-300 meters depth, Ancient Sands becomes accessible after purchasing the Pufferfish Tube. This biome is characterized by its distinctive sand waterfall and serves as the primary mid-game farming area.

Key NPCs and Their Locations

Marcus – Found near Crazy Jeff’s cave, right next to a giant skeleton. He sells the Crossbow Gun ($5,000) and Boat Tube ($5,000), which are essential for full exploration of this biome.

Crazy Jeff – The most important NPC in Ancient Sands! Located in a cave with air replenishment pods, he sells the crucial map for navigation. His cave also provides safe oxygen replenishment spots.

Grumpy Hank – Located southwest of Crazy Jeff’s store. Be careful of sharks in this area! He sells the Rukiry Tube ($35,000), which is necessary for reaching Spirit Roots.

Suspicious Fisher – Provides side quests and helpful items for your progression.

Optimal Progression Path

Farm near Crazy Jeff’s cave entrance – The fish here sell for more than Forgotten Deep, and you can quickly return for oxygen
Purchase Crossbow Gun and Boat Tube ($10,000 total) from Marcus
Progress through Marcus’s quests – These provide excellent money and EXP rewards
Save for Wasted Gun ($23,000) and Rukiry Tube ($35,000) – Total $58,000 needed
Complete Grumpy Hank’s quests – Additional money and progression rewards

Ancient Sands Farming Strategy

The area around Crazy Jeff’s cave is your goldmine. Fish here sell for significantly more than in Forgotten Deep, and the cave provides quick oxygen access. I recommend spending several hours here farming to afford the Rukiry Tube before attempting Spirit Roots.

Ocean Biome: The Shipwreck Territory

Often overlooked but crucial for progression, the Ocean biome sits at 280-300 meters depth, located far east of the Kraken in Forgotten Deep Dome.

Ocean Biome NPCs

Diver – Found sitting on top of a submarine deep in the water. He provides lucrative delivery quests that are essential for unlocking Spirit Roots.

Lost Captain – Located on a wrecked ship. Completing his entire quest chain (requires level 35) unlocks the hidden Angler’s Cave biome.

Morveth – Found in caves beneath the Ocean biome. He provides your first Ruby Rune, which is essential for late-game progression.

Ocean Biome Importance

While often treated as a transition area, the Ocean biome contains several critical progression elements:

Diver’s delivery quests are required for Spirit Roots access
Lost Captain’s quest chain (level 35+) unlocks Angler’s Cave
Morveth’s Ruby Rune is essential for endgame content

Spirit Roots: The Endgame Paradise

Reaching Spirit Roots (350-460 meters) marks your transition to endgame content. This biome requires the Rukiry Tube or Zepline Tube for access and features the most valuable fish in the game.

Spirit Roots NPCs and Quests

Isolde and Lumi – The main quest NPCs in Spirit Roots. Complete their quests to unlock the water barrier that leads to the best content.

Victor – Found behind the water barrier after completing Isolde’s quests. He provides the Lost Spirit Tube ($225,000) and Lost Spirit Gun ($93,250) – total $318,250.

Golem – Provides significant rewards for quest completion.

King Cat – Awards the prestigious King’s Fortune artifact.

Spirit Roots Progression Strategy

Accept Lumi and Isolde’s quests immediately – Progress these while fishing normally
Farm fish outside Spirit Roots entrance – These sell considerably more than Ancient Sands fish
Purchase Oxy Tube ($65,000) and Magroot Gun ($40,000) – Total $105,000 needed
Complete Isolde’s quests to unlock the water barrier
Save for Lost Spirit Tube and Gun ($318,250 total)
Farm until level 35 to unlock Lost Captain’s quests

Endgame Farming in Spirit Roots

The area outside Spirit Roots entrance becomes your primary money source in endgame. Fish here sell for premium prices, and with the Lost Spirit equipment, you can access the underground cave area containing legendary fish like the Eyefish.

Hidden Biomes: Secret Areas and Endgame Content

Angler’s Cave: The Ultimate Challenge

Essential Navigation Tips

Map Acquisition

The map is crucial for efficient navigation. Here’s how to get it:

Reach Ancient Sands (requires Pufferfish Tube)
Find Crazy Jeff’s cave (look for his sign under the giant arch)
Purchase the map from Crazy Jeff for navigation assistance

Teleporter System

Unlock the teleporter early by completing the Scientist’s quest:

Find required items: toilet paper, toilet, door, power relays
Benefits: Fast travel between biomes for a small fee
Essential for: Players without Sell Anywhere Gamepass who need to return to Kraken frequently

Oxygen Management

Each biome has different depth requirements:

Always check your tube’s depth limit before diving deeper
Use oxygen replenishment pods in caves (Ancient Sands has several)
Return to surface or safe zones before oxygen runs out
Consider races with oxygen bonuses for safer deep diving

Common Mistakes to Avoid

Based on my extensive gameplay experience, here are the most common mistakes players make:

Buying every tube and gun – Skip Fire Tube and Air Rifle Gun; they’re waste of money
Not buying the Radar early – This $250 investment pays for itself quickly
Ignoring side quests – Virelia and Mr. Black’s quests overlap with main quests
Dying with valuable fish – Use Billy’s Bank to store rare catches
Rushing to deeper biomes – Farm adequately in each area before progressing
Forgetting oxygen management – Always monitor your depth vs. tube capacity

Advanced Biome Strategies

Efficient Money Making

Forgotten Deep (Early Game): Focus on completing quests and catching common fish quickly. The volume of catches matters more than individual value.

Ancient Sands (Mid Game): Farm near Crazy Jeff’s cave entrance. The higher fish values combined with quick oxygen access make this the best mid-game farming spot.

Spirit Roots (End Game): Fish outside the entrance area. These sell for premium prices and are accessible with mid-tier Spirit Roots equipment.

Race Optimization

Certain races provide advantages for specific biomes:

Kraken and Sea Angel (S-Tier): Best overall for deep diving
Shark and Vampire Squid (A-Tier): Excellent for aggressive areas
Crab (A-Tier): Great for defensive play in dangerous biomes

Artifact Synergy

Different biomes benefit from different artifact combinations:

Forgotten Deep: Feather + Fish Bag + Sea Star (speed and capacity)
Ancient Sands: Mutated Skull x2 + Tank (damage and defense)
Spirit Roots: Divine Hour Glass + Eternal Crystal + King’s Fortune (endgame optimization)
