Where to Find the Angler Cave Door

The Angler Cave is locked behind a giant secret door located in a hidden section of the Abyss map. Near the entrance, you’ll find an NPC who gives a long questline. This character is the key to unlocking the cave. Before anything else, you must talk to this NPC to begin the chain of quests that eventually rewards you with a special key. To start the questline, you must:

• Reach Level 35
• Pay 10,000 cash

After that, the NPC gives several multi-stage quests that involve catching rare fish, gathering mutated variants, and finding treasure chests. The tasks include things like:

• Catching sharks and rare fish (including legendary ones)
• Collecting multiple mutated fish types
• Opening dozens of treasure chests
• Gathering geodes and special materials

Some of the hardest parts involve hunting shadow or rare mutations, which can take a long time due to spawn rates. Server hopping can help speed this up. Once every objective is completed and turned in, the NPC rewards you with a Pirate Key, which is used to open the sealed door.

How to Open the Angler Cave Door?

With the Pirate Key in your inventory, return to the giant door and interact with it. The entrance opens to reveal the Angler Cave. Inside, you’ll immediately notice:

• Sea mines that deal extremely high damage
• Groups of aggressive piranhas
• Large numbers of angler fish
• Hidden treasure chests

Move carefully. Sea mines can almost instantly kill you. Even with high oxygen capacity, touching one is extremely risky.

Any Secret in Angler Cave?

One of the biggest rewards inside the cave is a hidden shop area. This merchant sells powerful late-game equipment, including:

• A top-tier Ruined harpoon gun with very high damage
• An advanced Ruined tube that increases oxygen and speed

These items are considered some of the strongest gear available and greatly improve mobility and survivability. You’ll need to return to a safe zone to equip certain upgrades.

Survival Tips for the Angler Cave

Exploring the cave safely requires preparation:

• Bring multiple oxygen tanks
• Avoid sea mines at all costs
• Clear piranhas quickly to prevent constant damage
• Loot chests while watching your oxygen level

Even with the best tube, sea mines can nearly drain your oxygen in a single hit. Treat them as instant-death hazards and navigate slowly.

Why Unlocking the Angler Cave Is Worth It

Although the questline is long and sometimes frustrating, unlocking the Angler Cave gives access to:

• Endgame weapons and tubes
• New enemies and farming opportunities
• Extra treasure chests
• Unique exploration content

Starting the NPC quests as soon as you hit level 35 is recommended, since mutation objectives can take a long time to finish. The Angler Cave is one of the biggest progression milestones in Abyss. It tests your patience with long quests, but rewards you with elite gear and a dangerous new zone to explore. If you’re serious about advancing in the game, unlocking this cave early will make the rest of your journey much smoother.
