The Relic Piercer is the only harpoon gun in Fisch that you build yourself rather than buy from a location. It is made at the Harpoon Gun Crafting station on Ancient Isle, and its hardest requirement is a mutated fish catch that needs a special rod to reel in.
Quick answer: Bring 3 Moonstone, 1 Meg’s Spine (Marrow), and 2 Scrap Metal to the Harpoon Gun Crafting station on Ancient Isle, then craft. The Meg’s Spine (Marrow) must be caught at Ancient Isle using the Marrow Rod.
Relic Piercer crafting materials
The full recipe uses three ingredients. Two of them are common, but the Meg’s Spine (Marrow) is the piece that turns this into a longer grind.
| Material | Amount | How to get it |
|---|---|---|
| Moonstone | 3 | 1.4% chance from a Meteor at Ancient Isle |
| Meg’s Spine (Marrow) | 1 | Fish at Ancient Isle with the Marrow Rod |
| Scrap Metal | 2 | Catch anywhere in the Ocean with the Training Rod |
Scrap Metal and Moonstone can be stockpiled while you work toward the harder catch. Moonstone only drops from Meteors on Ancient Isle at a low rate, so start collecting it early.
Get the Marrow Rod first
Meg’s Spine is a Mythical catch found at Ancient Isle. The base version has a 12% catch rate, and the Marrow mutation the recipe asks for sits around 6%. To have a real chance at hooking the Marrow version, you need the Marrow Rod because of its high Luck stat.
The Marrow Rod is itself a crafted item. Its parts come from a questline on Fishfest Island, and the recipe is listed below.
| Marrow Rod material | Amount |
|---|---|
| Mysterious Skull | 1 |
| Mysterious Spine | 1 |
| Mysterious Fang | 1 |
| C$ | 100,000 |
Once built, the Marrow Rod carries Lure Speed 30%, Luck 80%, Control 0.1, Resilience 11%, and a Max Kg of 100,000. That Luck value is the reason it is the tool of choice for the Marrow catch.
Catch Meg’s Spine (Marrow) at Ancient Isle
Note: A normal Meg’s Spine will not satisfy the recipe. The crafting menu specifically requires the Marrow version, so confirm the mutation name before you head to the station.
Craft the Relic Piercer
If the craft button stays greyed out, the usual cause is holding a plain Meg’s Spine rather than the Marrow one, or being short on Moonstone since it drops slowly from Meteors.
Relic Piercer stats and pull mechanic
Its in-game description reads: “Forged from ancient materials. Requires rapid effort to pull, but turns quick reflexes into incredible progress.” That line points directly at how it reels in a catch.
| Stat | Value |
|---|---|
| Power | 50 |
| Range | 20 studs |
| Reload | 2.50s |
| Velocity | 50/ps |
| Resilience | -5% |
| Accuracy | 20% |
| Max Kg | 50,000 |
Unlike some harpoon guns, the Relic Piercer does not reel automatically. After you hook a roaming fish, you have to click the “PULL!” prompt repeatedly to close the distance. Each click adds progress, and missing the timing slows that progress down, so the faster and cleaner your clicks, the quicker the catch lands.
The Relic Piercer arrived with the Harpoon Guns update, which added ranged fishing and the pull minigame to Fisch. If you want the free bonus gun tied to that launch, the code HarpoonGunsAreAwesome can be redeemed in game, though promo codes expire without warning.
