All Fish to Unlock Cryolash Rod in Fisch (Complete Boreal Pines Bestiary Guide)

Unlocking the Cryolash Rod in Fisch is not about luck or raw money alone. This rod is locked behind full progression, meaning you must complete 100% of the Boreal Pines Bestiary before you can buy it. Many players get stuck because they miss one or two fish without realizing it. This guide breaks down every fish you need, where to find them, and what method is required so you can unlock the Cryolash Rod without confusion. Also check out our Fisch Codes for more rewards!

Cryolash Rod Unlock Requirement Explained

Before listing the fish, it is important to understand the requirement clearly.

• Cryolash Rod price: 3,500,000
• Unlock condition: 100% Boreal Pines Bestiary
• If even one fish is missing, the rod will stay locked

Boreal Pines fish are split across three main fishing locations, and some of them cannot be caught with a rod.

Location 1: Crystal Fisher Cave Fish List

This cave is one of the most important areas in Boreal Pines. It contains rare and high-tier fish, including the hardest one in the update.

Fish Found in Crystal Fisher Cave

• Glacial Squid (Mythic)
• Frostwyrm (Exotic)

Important Notes

• Frostwyrm only spawns during Frostwyrm Hunts
• Spawn chance is much higher during Winter
• Best bait for Frostwyrm: Sapphire Krill & Frost Nova
• Sundials can be used to help trigger spawns

Both fish must be registered in your bestiary to progress.

Location 2: Frozen Lake Near the Merchant

This frozen lake is easy to overlook, but it contains several unique Boreal Pines fish. The lake has multiple fishing pockets, and you must fish in all of them.

Fish Found in Frozen Lake

• Boreal-native common fish
• Rare cold-water variants specific to Boreal Pines

Important Notes

• Walk around the entire lake
• Fish each pocket until no new entries appear
• Missing one pocket often causes bestiary progress to stall

This location usually completes a large portion of your missing entries.

Location 3: Mountain Lake Above Cryolash Cabin (Cage-Only Fish)

This area is where most players get stuck. Several fish here cannot be caught normally and require cages.

Required Tool

• Reinforced Cage

Regular cages will not work for bestiary completion here.

Cage-Only Fish List

• Grease Sea Urchin
• Snow Crab
• King Crab (Legendary)

Important Notes

• Each reinforced cage can catch up to four fish
• Place multiple cages to speed up progress
• These three fish are mandatory for Cryolash unlock

If any of these are missing, Cryolash will remain locked.

Common Mistakes That Block Cryolash Unlock

Many players think they completed everything but still cannot buy the rod. These are the most common issues:

• Forgetting to use cages at the mountain lake
• Missing Frostwyrm due to season ending
• Not fishing all frozen lake pockets
• Leaving Crystal Fisher Cave too early

Double-check your bestiary if Cryolash is still unavailable.

Final Steps to Buy Cryolash Rod

Once all fish from:

• Crystal Fisher Cave
• Frozen Lake
• Mountain Lake (cage-only)

are registered, return to the Cryolash Cabin and interact with the rod again. The purchase option will unlock immediately once your bestiary hits 100%.

Unlocking the Cryolash Rod in Fisch is a true progression challenge, not a quick grind. Every fish in Boreal Pines matters, especially cage-only catches and Frostwyrm. Focus on completing each location carefully, prioritize winter hunting, and double-check your bestiary before assuming you are done. Once unlocked, Cryolash becomes one of the strongest permanent rods in the game and a major upgrade worth the effort.
