Harpoon Monstrous Cusk’s head in Gloomy Crevice, follow it into The Deep, hook its head again, and finish the pulling minigame.
You’ll need harpoon guns to catch Monstrous Cusk in Fisch. Once you’ve drawn it out, positioning and well-timed pulls matter. Keep your focus on filling the pulling minigame’s bar—that’s what completes the catch.
Find and prepare for a Monstrous Cusk Hunt
Your starting point is Gloomy Crevice, the green-lit area within The Deep. Equip diving gear before entering, and look near the bottom for Monstrous Cusk when its hunt spawns.
Hunts spawn naturally through Disturbance, with a listed spawn threshold of 1,000 Risk.
For a spawning setup, activate an Eclipse Totem before fishing in Gloomy Crevice with a high-disturbance rod. The totem increases the chance of a huntfish spawn, but doesn’t guarantee Monstrous Cusk.

Catching Faceless Cusk in the same area also contributes to awakening Monstrous Cusk. Plague Reaver, Boom Ball, Ignorous Rupturer, and Spirit Binder are fishing rods and cannot be caught as part of any sequence.
Each server has its own hunt, with one Monstrous Cusk available and only one active hunt at a time. The event lasts 10 minutes and ends automatically when the fish is caught. Any player can fire the initial harpoon shot or perform the later head shot that hooks it, so participation isn’t reserved for whoever draws it out.
Lure Monstrous Cusk out and finish the harpoon encounter
The pulling minigame puts valid inputs among traps. Read the targets carefully before committing to a click.
How to complete the Monstrous Cusk harpoon catch
Draw the fish into open water, then hook its head and work through the pulling prompts.
STEP 1/7
14%
Equip your Harpoon Gun and target the head
Fire your Harpoon Gun repeatedly at Monstrous Cusk’s head to draw it out of Gloomy Crevice. Body and flank hits won’t hook it, and flank strikes barely slow it.
STEP 2/7
29%
Follow it into The Deep
Follow Monstrous Cusk as it leaves the crevice and swims into the open water of The Deep.
STEP 3/7
43%
Move above its head while keeping your distance
Position yourself above its head without getting close enough to lose HP. Keep that separation as you line up the next shot.

STEP 4/7
57%
Hook the head again
Fire another shot directly at its head to hook Monstrous Cusk and start the harpoon minigame.
STEP 5/7
71%
Click the valid pulling targets
Click the white target rings marked PULL! as the reticle crosses them. Missing valid pulses reduces progress speed and can break the line.
STEP 6/7
86%
Re-hook the fish after a failed attempt
If the attempt ends with “it got away…”, locate the fish again and aim another harpoon shot at its head. An escaped attempt can be followed by another engagement, so reposition before retrying.
STEP 7/7
100%
Fill the catch progress bar
Keep pulling successfully until your bottom progress bar fills completely and the Monstrous Cusk catch banner appears. This minigame can take a while, so continue following its prompts until it ends.

The weather, time, season, and bait entries are preferences, not extra requirements for joining the encounter. Casting a rod and waiting won’t complete this catch; the capture itself uses the harpoon procedure.
Collect catch rewards and farm Monstrous Cusk Tooth
Catch Monstrous Cusk awards 22,000 XP, and its listed rate is C$3.46 per kilogram. One successful catch weighed 10,123.9 kg, an individual result rather than a minimum, average, or guaranteed weight.
After a catch, open your backpack and look for Monstrous Cusk Tooth. It’s a rare drop used to craft the Cusk Purger rod, so repeat catches across hunts if you’re pursuing the material. A successful capture doesn’t guarantee a tooth.

Frequently Asked Questions
How do passive abilities interact with Monstrous Cusk?
Your passives have a lower chance of obtaining Monstrous Cusk because its Level 2 passive-chance reduction, labeled Passive Chance /20, divides the applicable passive chance by 20. Bypassing Passive Blocks doesn’t avoid that penalty, since the reduction applies to those abilities too.
