The Gloomy Crevice sits among the deepest fishing zones in Fisch, and its bestiary holds 21 separate entries. Filling it out means matching the right conditions for a mix of common pickups, legendary catches, and one exotic that only shows up during a live server event. Here is how to reach the zone, what gear to carry, and the precise sequence for landing the Monstrous Cusk.
Quick answer: Dive deep past the Nereus main quest building to enter the Gloomy Crevice, catch each of the 20 standard entries by matching their bait, weather, time, and season, then complete the global Monstrous Cusk hunt with a harpoon gun to close out all 21.
How to reach the Gloomy Crevice
The Gloomy Crevice is a deep-water zone reached by diving down near the Nereus main quest building. Head to that building, then descend past it into the depths until you drop into the crevice itself. Because this is one of the lowest points you can fish, expect it to gate several of its creatures behind strict environmental conditions.
Gear you need for the deep entries
Most of the bestiary comes down to lining up the correct bait, weather, time of day, and season for each entry. For the heavier deep-water creatures, a harpoon gun does the job far better than a standard rod. Three stand out for this zone.
- Relic Piercer
- Trident Striker
- Crystal Crasher
Keep bio-infused coral on hand as well. It becomes important during the Monstrous Cusk hunt, where the harpoon minigame carries a heavy progress penalty.
Confirmed Gloomy Crevice bestiary entries
The lineup ranges from common items and eels up to legendary and mythical fish, capped by the exotic Monstrous Cusk. These are the entries confirmed in the zone.
| Entry | Notes |
|---|---|
| Crushed Diving Helmet | Recovered item; larger “Big” variant weighs in around 10.3kg |
| Slender Snipe Eel | Light catch, seen as low as 0.1kg |
| Renate’s Eelpout | Small catch around 0.2kg |
| Electric Shortspine Thornyhead | Small catch around 1.7kg |
| Atlantean Abyssal Skate | Heavier deep-water skate, seen near 11.8kg |
| Yeti Crab | Deep-zone crustacean |
| Faceless Cusk | Deep-water fish tied to the crevice |
| Monstrous Cusk | Exotic; only appears during the global hunt event |
Note: Each entry has its own bait, weather, time, and season combination, so work through them by swapping conditions rather than fishing blindly in one spot.
How to catch the Monstrous Cusk
The Monstrous Cusk is the exotic entry and the hardest to secure, because it does not sit in the pool waiting for you. It spawns only when a special global hunt event begins, and it retreats deeper into the crevice as you fight it. Treat it like a boss chase.
Confirming the catch and common misses
You know a standard entry counted when the catch confirmation appears and the bestiary slot fills in. For the Monstrous Cusk specifically, completing the minigame registers the exotic in your log. If the hunt ends before you finish, you will see the event resolve with the message that the Monstrous Cusk has retreated into the crevice, which means it despawned and you will need to wait for the next event to try again.
The two most common reasons the Cusk slips away are arriving too late after the chat announcement and stalling out on the minigame because of the -90% progress penalty. Both are solved by moving quickly at the start and having bio-infused coral ready before the fight. With every standard entry logged and the Cusk secured, all 21 slots in the Gloomy Crevice bestiary are complete.
