Fisch: Best Enchant for the Frost Biter Harpoon Gun

The Frost Biter is a harpoon gun in Fisch, sold for 270,000 C$ at Boreal Pines, and its value on the water comes entirely from one trait. Every time a pull button appears while you are reeling, the weapon freezes it in place for a short moment. That freeze window is not fixed. It grows with the weapon’s Resilience stat, which makes your enchant choice the single biggest factor in how forgiving the Frost Biter feels.

Quick answer: Enchant the Frost Biter with Stable. It adds 20% Resilience, raising the weapon from 20% to 40%, which keeps each pull button frozen longer and gives you more time to click it.

Why Stable is the best enchant for the Frost Biter

The Frost Biter’s freeze mechanic scales directly with Resilience. Higher Resilience means the pull button stays frozen for a longer stretch, so the enchant that pushes Resilience the most is the one that pays off here.

Stable adds a flat 20% Resilience. Applied to the Frost Biter’s base 20%, that brings the total to 40% and roughly doubles the effective freeze duration. In practice, this turns fast, panic-inducing pull prompts into clicks you can hit calmly, which is exactly what you want against heavy or evasive catches in the Boreal Pines area.

Note: Because the whole point is extending the freeze window, prioritize Resilience over speed or luck options on this weapon specifically. Enchants that ignore Resilience do nothing for the Frost Biter’s signature mechanic.

How to apply the enchant to the Frost Biter

Harpoon guns are enchanted the same way as rods, using a Relic at the Keepers Altar beneath the Statue of Sovereignty. The altar is only active at night, and the roll is random from the Relic’s pool, so you may need several attempts before Stable lands.

Secure a Relic and travel to the Statue of Sovereignty. Talk to Cole and pay 400 C$ for a single Token, or 100,000 C$ for unlimited access, then take the elevator down to the Keepers Altar.

Equip the Frost Biter and hold it out. To enchant a harpoon gun, you must be holding the harpoon itself when you interact with the altar, not a fishing rod.

Interact with the pedestal to consume the Relic and apply a random enchant. Repeat with more Relics until you roll Stable. You can confirm it worked by checking the colored enchant prefix on the weapon’s name and the enchant details shown above the hot bar when it is equipped.

If you would rather skip the trip to the altar entirely, the Enchant Anywhere gamepass lets you enchant from any location.

The Frost Bite mutation bonus

Beyond the freeze mechanic, the Frost Biter has a 40% chance to apply the Frost Bite mutation to fish it catches, and that mutation carries a 6x value multiplier. Stable does not change this chance, but pairing the reliable catches from a longer freeze window with a high-value mutation makes the weapon a strong pick for grinding the Boreal Pines region.

Put simply, Resilience is the stat that defines this harpoon gun, and Stable is the cleanest way to raise it. Roll for it, confirm the prefix on the weapon, and the difficult pull prompts that used to slip away will hold long enough for you to land them.
