Getting Started: Winter Frost Event Setup

Step 1: Meet Vanya – Your Winter Fishing Mentor

Before you can start catching Frostspore Fish, you’ll need to kickstart the Winter Frost Event by speaking with Vanya, the fishing hobby mentor. Here’s exactly where to find her:

Location: Northern beach of Onsen Mountain
Time: During Winter Frost Event only
What to do: Complete the short Winter Frost introductory quest

This quest is straightforward and designed to get you started quickly. Vanya will explain the basics of Frostspore Fish and unlock the ability to catch them in the Old Sea area.

Step 2: Check Your Fishing Level

Great news! You only need Fishing Hobby Level 1 to catch all Frostspore Fish. This makes the event accessible to everyone, whether you’re new to fishing or have been doing it for a while.

Step 3: Optimize Your Equipment

While not required, I highly recommend equipping these items to maximize your catch rate:

Mermaid Fish Attractor: Increases spawn rates
Perfume: Improves catch success rate

These items will significantly reduce your grinding time and help you complete your winter fish collection faster.

All Winter Fish: Complete Catching Guide

Frostspore King Crab

Location: Old Sea
Shadow Size: Large
Best Time: Any time (24/7)
Weather: All weather conditions
Difficulty: Easy

The Frostspore King Crab is one of the easiest winter fish to identify and catch. Its large shadow makes it easy to spot from a distance, and since it spawns in the Old Sea alongside other winter fish, you’ll have plenty of opportunities to catch it.

Pro Tips for Frostspore King Crab:

Look for the largest shadows in the Old Sea
Use your Mermaid Fish Attractor for faster spawning
Try fishing during peak hours for better results
Save your game before attempting difficult catches

Frostspore Ocean Fish

Location: Old Sea
Shadow Size: Large
Best Time: Any time (24/7)
Weather: All weather conditions
Difficulty: Easy

The Frostspore Ocean Fish is essentially an infected variant of the common ocean fish, but with that beautiful icy glow that makes Frostspore Fish so desirable. Like the King Crab, it appears with a large shadow in the Old Sea.

Catching Strategy:

Focus on large shadows (same size as King Crab)
Be patient – they spawn regularly throughout the day
Use Perfume to reduce failed catches
Keep track of which large shadows you’ve already tried

Frostspore Puffer Fish

Location: Old Sea
Shadow Size: Medium
Best Time: Any time (24/7)
Weather: All weather conditions
Difficulty: Medium

The Frostspore Puffer Fish stands out with its compact, frozen appearance. Its medium-sized shadow makes it distinguishable from the larger winter fish but still visible enough to spot easily.

Advanced Techniques:

Medium shadows are your target here
Don’t confuse them with small shadows (Seahorse)
Time your casts carefully – puffer fish can be tricky
Consider using better fishing rods if available

Frostspore Seahorse

Location: Old Sea
Shadow Size: Small
Best Time: Any time (24/7)
Weather: All weather conditions
Difficulty: Hard

The Frostspore Seahorse is the most challenging of the common winter fish due to its small shadow size. This delicate creature is easy to miss if you’re not paying close attention to the water.

Expert Tips:

Scan the water carefully for small shadows
Don’t dismiss small shadows as regular fish
Use high-quality fishing equipment for better control
Practice your timing – small fish require precise casting

Frostspore Whale Shark: The Ultra-Rare Prize

Location: Old Sea
Shadow Size: Variable
Best Time: Only during “Hidden Movement” phase
Weather: All weather conditions
Difficulty: Extremely Hard

The Frostspore Whale Shark is the crown jewel of winter fishing in Heartopia. This ultra-rare fish only appears during special “Lucky” extra phases of the Winter Frost Event.

How to Trigger the Whale Shark Phase:

Wait for the message: Keep fishing until you see “hidden movement in the water”
Act quickly: This phase is temporary and doesn’t last long
Cast at every shadow: The Whale Shark can appear randomly among other fish
Don’t give up: You might complete multiple events without seeing it

Whale Shark Hunting Strategy:

Participate in every Winter Frost Event
Stay in the Old Sea during the entire event duration
Have your best equipment ready
Save frequently in case you need to retry
Don’t get discouraged – it’s extremely rare by design

Advanced Winter Fishing Strategies

Time Management

Since all Frostspore Fish spawn 24/7 regardless of weather, you don’t need to worry about timing your fishing sessions. However, I recommend:

Peak Hours: Fish during server peak times for more active spawning
Event Duration: Focus on the Winter Frost Event period
Multiple Sessions: Break up your fishing into shorter, focused sessions

Location Optimization

The Old Sea is your primary location for all winter fish. Here’s how to maximize your efficiency:

Stay in one area: Don’t waste time traveling between locations
Learn shadow patterns: Each fish type has consistent shadow sizes
Rotate fishing spots: Move around the Old Sea to trigger more spawns

Equipment Strategy

While Fishing Level 1 is sufficient, better equipment will help:

Mermaid Fish Attractor: Essential for serious collectors
Perfume: Reduces failed catches significantly
Upgraded Rods: If available, use the best rod you have
Special Bait: Check for event-specific bait items

Common Mistakes to Avoid

1. Ignoring Small Shadows

Many players focus only on large shadows and miss the Frostspore Seahorse. Always check small shadows!

2. Missing the Whale Shark Phase

The “hidden movement” message can be easy to miss if you’re not paying attention. Stay alert!

3. Not Using Equipment

Don’t try to catch winter fish without proper equipment. You’ll waste time and get frustrated.

4. Giving Up Too Early

The Whale Shark is designed to be extremely rare. You might need multiple events to find it.

5. Not Saving Progress

Save your game frequently, especially before attempting rare catches.

Fish Not Spawning
