To get the Cusk Purger in Fisch, reach the Ancient Archives Crafting Anvil and craft it with Deep update materials, including Monstrous Cusk Teeth, Abyssal Biofluid, Radiant Prism Scales, Line of the Deep, Hardened Chitin, Refined Scrap, Ancient Bone, and 750,000 C$.
If you are searching for Cusk Purged Rod or Cusk Purged Rod, you are looking for the current Cusk Purger. It is not a shop purchase; it is a Deep craft that asks you to farm Outer Deep, Lower Deep, and the Cartographer quest before you return to the anvil.

The name mismatch mostly comes from early player wording, but the recipe item itself is Cusk Purger. Use this as your pre-grind check before heading back to Ancient Archives.
Cusk Purger material locations
| Material | How to get it |
|---|---|
| Monstrous Cusk Tooth ×3 | Harpoon Monstrous Cusk in Lower Deep; each successful boss catch gives 1 tooth. |
| Abyssal Biofluid ×3 | Catch Luminous Hake in Outer Deep; it has a 20% drop chance. |
| Radiant Prism Scale ×2 | Fish or harpoon fish in Outer Deep until the local fish drop the scales. |
| Line of the Deep ×1 | Complete the Cartographer quest in The Deep, including the required catches, Outer Deep bestiary work, and Radiant Prism Scale turn-in. |
| Hardened Chitin ×3 | Farm catches in Outer Deep; current numbers put it around a 1 in 40 drop. |
| Refined Scrap ×3 | Fish in Outer Deep for general drops. |
| Ancient Bone ×3 | In Version 1.96.0, this recipe line is still marked TBA. |
Finish the Cartographer quest while farming Outer Deep so Line of the Deep, Radiant Prism Scales, Hardened Chitin, and Refined Scrap progress together.

Monstrous Cusk Tooth farming
For the teeth, start the chain in Gloomy Crevice by catching Faceless Cusk. That catch awakens Monstrous Cusk, so Faceless Cusk is the trigger, not the tooth drop.
The reward comes from the harpoon boss catch in Lower Deep, not from ordinary fishing. During the chase toward Deep City, flank hits slow Monstrous Cusk and headshots deal more damage; repeat successful catches until you have 3 Monstrous Cusk Teeth.
Cusk Purger stats and Deep effect
| Stat | Value |
|---|---|
| Lure Speed | 88% |
| Luck | 225% |
| Control | -0.05 |
| Resilience | 25% |
| Max kg | Infinite |
The Cusk Purger is built around high luck, infinite weight capacity, and a control penalty. Its numbers are:
Its special effect creates a vacuum around your line, pulling predatory Deep creatures toward your fishing line. That is what makes it a Deep-focused rod instead of only a stat upgrade.
Cusk Purger farming mistakes to avoid
Bring a harpoon plan for Monstrous Cusk instead of treating it like a normal rod catch. Faceless Cusk only wakes the boss, so farming the trigger fish alone will not hand you Monstrous Cusk Teeth.
Do not leave the Cartographer quest for later if you are already spending time in Outer Deep. Line of the Deep is mandatory, and the same region feeds several other recipe drops.
Use The Deep recipe information from Version 1.96.0 onward. Older Cusk-related posts from before August 8, 2026 can point you toward the wrong name, wrong material names, or incomplete requirements.
