Fisch Absolute Darkness Event Guide

The Absolute Darkness event, introduced with The Depths update, is one of the most elusive and rewarding events in Fisch. Spawning randomly and lasting just under 10 minutes, this event transforms The Depths into a pitch-black abyss, making navigation nearly impossible.

How to trigger the Absolute Darkness event in Fisch

The only reason to wait around for the Absolute Darkness event is to catch the Ancient Depths Serpent, an Exotic fish that is exclusive to the event.

Catching the Ancient Depth Serpent requires specific conditions. It only spawns during the Absolute Darkness event at night, which is a rare event that you could be waiting around hours for. If you’re having trouble getting to The Depths when the event is active, consider buying Sundial Totems from the cave on top of Sunstone Island; coordinates (-1220, 195, -1045). These totems cost 2,000C$ each and allow you to manually shift the in-game day/night cycle.

Sundial Totems are single-use items, and triggering the event can take many, many attempts. In my experience, I went through over 20 Sundial Totems before finally encountering the Absolute Darkness event, so be sure to stock up. You'll be there a while. Another important tip when using Sundial Totems is to wait a few minutes after nightfall before activating another. The Absolute Darkness event doesn’t always start immediately as the celestial cycle shifts to night, so a bit of patience can save you from wasting totems unnecessarily.

Preparing for the Absolute Darkness event

Before heading to The Depths, you’ll need an The Depths Key, which is an item of Exotic rarity that you can get by fishing it out of Strange Whirlpools or anywhere in Vertigo. Use a Magnet for betting luck when trying to reel one in, and listen out for a high-pitched twinkly chime sound; this signals that you've hooked a key. Once you have the key, use it to unlock the large, black and red gate that leads to The Depths. You can find this in Vertigo, surrounded by red crystals.

Keep in mind that leaving or re-joining the game will reset your spawn to Moosewood and lock the door again, forcing you to retrieve another key.

I would also recommend investing in a Fish Radar; available at the Moosewood Docks for 8,000C$. This is the only way to find the spawn point for the Ancient Depth Serpent when the Absolute Darkness event hits, so you'll be completely directionless without one.

Ancient Depth Serpent location

During the Absolute Darkness event, a faint yellow glow appears in a specific area on the right side of the island that has the merchant and angler on it. You can only see the glow if your Fish Radar is enabled.

The event lasts under 10 minutes, and Ancient Depths Serpent has a preference for the Truffle Worm. Be sure to stock up on Truffle Worms before heading to The Depths. You can buy Volcanic Geodes from the Travelling Merchant to find this type of bait - though it is luck of the draw because not every geode contains Truffle Worms.

I recommend the Mythic Rod with either the Lucky or Hasty blessing to catch this fish. Lucky gives you 20% more Luck, and Hasty decreases your Lure time by 55%. Be sure to equip your Truffle Worm bait, too.
