Fish Species in Forgotten Deep

As the starting biome, Forgotten Deep contains common fish species perfect for early-game farming. You can catch basic fish here using your starter equipment. This area is ideal for building up your money before purchasing better tubes and guns.

Tips for Forgotten Deep

Complete all NPC quests in this area before moving deeper. The quest rewards provide substantial money that you will need to buy the map and upgrade equipment. The oxygen pods scattered throughout this biome make it easy to stay underwater longer while learning the ropes.

Ancient Sands Biome

Ancient Sands is a desert-themed underwater biome featuring sand waterfalls and ancient ruins. Located at depths between 100-200m, this area introduces slightly more challenge with a danger level of 2 out of 5. The sandy terrain creates unique visual effects and hides various treasures.

Depth Range: 100-200m

Danger Level: 2/5

Recommended Equipment: Plunger Gun, Basic Tube (upgraded)

Key NPCs in Ancient Sands

Crazy Jeff – The most important NPC in this biome. He sells the map for $2,450, which unlocks the minimap and makes navigation significantly easier. Save your money and buy this as soon as possible.

Monk – Offers quests related to spiritual items and artifacts found in deeper biomes.

Arthur – Provides quests involving the ancient ruins and hidden chambers within the sand areas.

Notable Features

The sand waterfall is the signature visual feature of Ancient Sands. Behind and around this waterfall, you can find hidden passages and treasure chests. The sunfish pet can be obtained through quests in this area.

Fish Species in Ancient Sands

Ancient Sands offers different fish species compared to Forgotten Deep. The sandy environment attracts bottom-dwelling fish that provide better rewards when caught. Use your Plunger Gun for effective fishing in this biome.

Tips for Ancient Sands

Prioritize buying the map from Crazy Jeff before anything else. Without the minimap, navigating to deeper biomes becomes significantly harder. The King Cat artifact can be found in this biome, which provides useful bonuses for exploration.

Ocean Biome

The Ocean Biome represents the open water area of Abyss, featuring vast expanses of deep blue water and the famous wrecked ship location. Spanning depths of 200-350m with a danger level of 3 out of 5, this biome requires better equipment than the previous areas.

Depth Range: 200-350m

Danger Level: 3/5

Recommended Equipment: Pufferfish Tube, Magroot Gun

Key NPCs in Ocean Biome

Builder Monkey – Offers construction-related quests and sells portable stash upgrades for inventory management.

King Cat – Located on the wrecked ship, provides high-value quests and sells rare items including the King Cat artifact.

Wrecked Ship Location

The wrecked ship is the central landmark of the Ocean Biome. Inside the ship, you will find multiple treasure chests, the King Cat NPC, and various artifacts. Be careful of sea mines scattered around the wreckage.

Fish Species in Ocean Biome

The open water attracts larger fish species that provide better money when sold. The Ocean Biome is excellent for mid-game farming once you have upgraded to the Pufferfish Tube. You can also find the Ancient Shark in deeper parts of this biome – check our guide on how to get Ancient Shark fast for tips.

Tips for Ocean Biome

Watch your oxygen carefully in this biome. The 200-350m depth range requires a decent tube upgrade to explore safely. The wrecked ship contains the best loot, but sea mines can damage you if you are not careful.

Spirit Roots Biome

Spirit Roots is a bioluminescent fungal biome featuring glowing plants, ethereal lighting, and unique creatures. Located at depths of 350-500m with a danger level of 3 out of 5, this visually stunning area contains some of the most valuable fish and items in the game.

Fish Species in Spirit Roots

Spirit Roots is home to the famous Eyefish, one of the most sought-after catches in Abyss. Read our complete guide on how to catch Eyefish in Spirit Roots for detailed location and strategy information. Other rare fish species in this biome provide excellent money-making opportunities.

Tips for Spirit Roots

Invest in a Lost Spirit Tube before spending significant time here. The depth range requires better oxygen management than previous biomes. The glowing environment can make it harder to spot dangers, so move carefully and use your minimap.

Sunken Wilds Biome

Sunken Wilds is a jungle sub-biome within Spirit Roots, added in the Jungle Update. This area features underwater vegetation, tree-like structures, and a higher danger level of 4 out of 5. Spanning depths of 400-500m, it offers some of the best endgame content currently available.

Depth Range: 400-500m

Danger Level: 4/5

Recommended Equipment: Zepline Tube, Ruined Gun or Wasted Gun

Key NPCs in Sunken Wilds

Thief Monkeys – Multiple monkey NPCs that offer various quests and can steal items if you are not careful. Completing their quests rewards unique mutations.

King Monkey – The leader of the monkeys, offers the most valuable quests in this biome and sells exclusive items.

Notable Features

The jungle environment creates a maze-like structure that makes navigation challenging. Without a good map and minimap, you can easily get lost in the vegetation. The area contains rare mutations that can only be obtained here.

Fish Species in Sunken Wilds

Sunken Wilds contains the rarest fish species in the game. These catches require high-level equipment and sell for significant amounts of money. This biome is ideal for endgame farming once you have maxed out your equipment.

Tips for Sunken Wilds

Do not attempt this biome without the Zepline Tube and a strong gun like the Ruined Gun or Wasted Gun. The danger level is high, and running out of oxygen at these depths is deadly. Bring oxygen pods if you plan extended farming sessions.

Hidden and Secret Locations

Beyond the main biomes, Abyss contains several hidden and secret locations that require specific actions to unlock. These areas offer unique rewards and challenges for dedicated explorers.

Angler Cave

Angler Cave is a hidden cave location featuring the King Anglerfish NPC. This area is not visible on the standard map and requires specific actions to unlock. Many players struggle to find this location, so here is what you need to do:

How to Unlock: Complete specific quest chains from NPCs in Spirit Roots and Ocean Biome. The Suspicious Fisher in Forgotten Deep provides hints about the cave location.

Danger Level: 4/5

Rewards: King Anglerfish offers exclusive fish species and rare items not found anywhere else in the game.

Bob’s Secret Duck Room

Bob’s Secret Duck Room is a hidden area containing a duck-collecting challenge. Finding all the ducks scattered throughout Abyss unlocks access to this room and its rewards.

How to Unlock: Collect all ducks hidden throughout the main biomes. The ducks are small and can be easy to miss, so explore thoroughly.

Rewards: Completing the duck challenge rewards exclusive items and achievements.

Valentine’s Event Location

During seasonal events like Valentine’s Day, Abyss adds temporary event locations with limited-time content. These areas disappear after the event ends, so explore them while available.

Availability: Limited time during Valentine’s event period.

Rewards: Exclusive event items, fish, and cosmetics.

How to Get the Map in Abyss

The map is essential for navigating Abyss efficiently. Without it, you must rely on memory and visual landmarks to find your way around.

Where to Buy: Purchase the map from Crazy Jeff in Ancient Sands biome.

Cost: $2,450

Benefits: Unlocks the minimap display showing your current location, biome boundaries, and points of interest. The map makes finding NPCs, teleporters, and hidden areas significantly easier.

Save money from early quests in Forgotten Deep to buy the map as soon as you reach Ancient Sands. The investment pays off immediately by reducing navigation frustration.

Teleporter System and Fast Travel

Abyss features a teleporter system (also called tele-toilets or teleporter bathrooms) that allows fast travel between biomes once unlocked.

How Teleporters Work: Each main biome has a teleporter location. After activating a teleporter, you can fast travel to it from any other activated teleporter.

Finding Teleporters: Look for toilet-like structures in each biome. The teleporter in Forgotten Deep is near Billy’s location.

Unlocking Teleporters: Simply approach and interact with each teleporter to activate it. Some require completing specific quests first.

Using teleporters saves significant travel time, especially when moving between distant biomes like Forgotten Deep and Sunken Wilds.

Equipment Progression by Biome

Your tube and gun determine how deep you can dive and what you can catch. Here is the recommended equipment progression:

Forgotten Deep: Bath Tube (starter), Plunger Gun

Ancient Sands: Oxy Tube, Magroot Gun

Ocean Biome: Pufferfish Tube, Lost Spirit Gun

Spirit Roots: Boat Tube or Lost Spirit Tube, Morveth’s Gun

Sunken Wilds: Zepline Tube, Ruined Gun or Wasted Gun

Each tube has a depth limit shown on its description. Exceeding this limit causes rapid oxygen depletion and eventual death. Always check your tube rating before diving into a new biome. For more on equipment choices, see our guide on the best races and weapons in Abyss.

Recommended Biome Progression Order

Following the right progression order makes your Abyss experience smoother and more enjoyable. Here is the recommended path:

Step 1: Complete all quests in Forgotten Deep. Build up money and buy basic upgrades.

Step 2: Move to Ancient Sands. Buy the map from Crazy Jeff immediately.

Step 3: Upgrade your tube and gun, then explore Ocean Biome for artifact hunting.

Step 4: Get a Lost Spirit Tube and tackle Spirit Roots. Complete Morveth’s quest chain.

Step 5: With maxed equipment, enter Sunken Wilds for endgame farming.

Step 6: Unlock hidden locations like Angler Cave and Bob’s Secret Room.

Skipping ahead to deeper biomes without proper equipment results in frequent deaths and wasted time. Progress naturally through each area. For money-making strategies to fund your progression, check out our guide on the fastest ways to make money in Abyss.

Oxygen Management Tips

Oxygen management is critical for survival in Abyss. Here are essential tips:

Watch Your Oxygen Bar: The blue bar below your health shows remaining oxygen. Return to the surface or an oxygen pod before it depletes.

Use Oxygen Pods: Scattered throughout biomes, these restore oxygen when approached. Memorize their locations for emergency situations.

Upgrade Your Tube: Better tubes allow deeper diving and slower oxygen consumption. Each tube upgrade significantly extends your underwater time.

Stay Within Depth Limits: Going deeper than your tube rating causes rapid oxygen drain. Check depth markers on your tube before exploring new areas.

Safe Zones: Each main biome has dome-shaped safe zones where oxygen regenerates automatically. Use these as rest points during long expeditions.
