To catch the Ancient Depth Serpent, fish in the yellow pool that appears in The Depths during the Absolute Darkness event. Bring Truffle Worm bait, use a Fish Radar to find the pool in the dark, and start fishing as soon as you locate it—the pool may vanish before the event ends.
Where and when to catch the Ancient Depth Serpent
Community guides place the Ancient Depth Serpent’s catch location in the event pool in The Depths, during Absolute Darkness. The event is reported to occur randomly, last about 15 minutes, and not be triggerable with a Sundial Totem. Night is listed as the fish’s preferred time, but Absolute Darkness—not a separate night-time requirement—is the key condition.
When the event begins, look for its yellow pool. The pool can disappear before the roughly 15-minute event is over, so finding it quickly matters more than waiting for the event’s full duration.
How to find and catch it
- Get access to The Depths. A community guide says access requires the Depths Key and a completed Vertigo Bestiary. This is secondary-source guidance; check the current in-game requirements in case an update has changed them.
- Bring Truffle Worm bait and a suitable rod. Truffle Worm is listed as the preferred bait. The available guides do not establish one universally best rod for this catch.
- Wait for Absolute Darkness. The event is reported to occur randomly, and a Sundial Totem will not force it to start.
- Use a Fish Radar to locate the pool. The radar is recommended because the event takes place in darkness. Head to the yellow pool when you find it.
- Fish in the pool immediately. It is the reported location for the catch, and it may disappear before the event ends.
What makes the catch difficult
The Ancient Depth Serpent is reported to move erratically and impose a -60% progress-speed penalty while reeling. Be prepared for a difficult catch rather than assuming a preferred bait or rod will remove the challenge. No dependable guide comparison establishes a best rod, so choose a suitable rod you can control well.

The in-game Bestiary entry, as reproduced by a community transcription, describes it as “A colossal, serpent-like creature with armored scales and glowing eyes, lurking in the abyss. The Ancient Depth Serpent is only active when The Depths go completely dark… No one knows where it goes in the meantime, possibly lurking in a secret cave?”
What is not firmly established
Community guides do not agree on the fish’s value and weight figures, and exact catch odds are not reliably established. Some listed environmental conditions are not corroborated consistently, so they should not be treated as confirmed requirements. The event-pool route and Truffle Worm preference are the practical guidance supported across the available guides; game mechanics may change with updates.
