How to Catch the Mossjaw in Fisch?

The Mossjaw is the crown jewel of the Lost Jungle update in Fisch, and for good reason. This ancient, moss-covered reptile fish is one of the most challenging catches in the game, requiring not just skill but also puzzle-solving abilities and perfect timing. Let me break down everything you need to know.

Understanding the Mossjaw

Before we dive into the catching process, it’s essential to understand what makes the Mossjaw so special:

The Mossjaw is an Exotic rarity fish described as “a hulking, moss-covered predator that lurks the deep within the jungle. Its scales are heavy with age, and its jaws snap through trees as easily as bone. Few dare the temple at night, for the Mossjaw waits there, patient and merciless.”

The Elder Mossjaw is the Secret rarity variant—even rarer and more challenging to catch. When you hook an Elder Mossjaw, you’ll notice a distinctive black exclamation mark (!) appearing above your character’s head.

Both variants share the same location and spawn conditions, but the Elder Mossjaw has significantly harsher penalties and is much harder to reel in successfully.

Location: Finding the Mossjaw Rest

The Mossjaw doesn’t appear in random locations like other fish. It’s exclusively found in the Mossjaw Rest pool, located deep within the Forgotten Temple area beneath the Lost Jungle Island.

However, reaching this location isn’t straightforward. You’ll need to solve a series of puzzles to gain access. Here’s how to get there:

Reach Lost Jungle Island: The island is located behind Sunstone Island. Follow the marker on your screen to locate it.
Enter the Forgotten Temple: Head to coordinates (-2603, 161, -2190) where you’ll find an opening with a rope attached. Use the rope to descend into the temple.
Meet the Jungle Adventurer: Inside, you’ll encounter the Jungle Adventurer NPC who will warn you about the dangers and give you the Temple Eye—a crucial item that allows you to teleport to the main temple entrance.
Solve the Five Rune Puzzles: This is the most challenging part. You need to solve five different puzzles in separate rooms to collect all five Runes.
Open the Gates: Once you have all five Runes, place them on the corresponding pedestals at the Temple Gates to unlock the Mossjaw Rest area.

The good news? You only need to complete this puzzle sequence once. After unlocking the Mossjaw Rest, you can access it freely using the Temple Eye for quick teleportation.

Complete Forgotten Temple Puzzle Guide

Solving the Forgotten Temple puzzles is crucial for accessing the Mossjaw Rest area. Based on my research and experience, here’s the complete guide to all five puzzle rooms:

Room I Puzzle: The Pattern Obby

Location: (-5234, -1758, -9620) How to reach: Take left from Room IV, move past the map, then take right at the next intersection.

This room features an obstacle course where you must jump on platforms in the correct sequence. Follow this pattern precisely:

Triangle → Square → Square → Triangle → Circle → Triangle → Square → Triangle → Circle

Touch the hand at the end to receive the Poisonous Spearhead and Rune Glyph.

Room II Puzzle: The Flooding Chamber

Location: (-4642, -1748, -10193) How to reach: Take right from Room IV. Look for the II mark on the top wall.

This room starts flooding immediately upon entry. You need to use railings and platforms to reach the top before drowning. It’s a challenging parkour section that will likely take several attempts to master.

Rewards: Toxic Core and Toxic Rune

Pro tip: Take your time and study the layout before making each jump. The patterns become more predictable once you understand the rhythm.

Room III Puzzle: The Spike Maze

Location: (-5405, -1759, -10231) How to reach: Take left from Room IV, walk straight until you find Room III after moving around the corner.

This room features deadly spikes protruding from the walls. You need to navigate carefully through the center path to reach the final Hand Piece without getting killed.

Follow this intersection pattern: Right → Left → Right → Left → Left → Left

Rewards: Barbed Spearhead and Spike Rune

Important: The pattern above is specifically for intersections. When there’s only one path, follow it naturally.

Room IV Puzzle: The Moon Trial

Location: (-5172, -1759, -10329) How to reach: Located right behind the Main Temple Door (accessible via Temple Eyes)

This puzzle involves pulling vines adjacent to moon symbols in the correct order. The catch? The vine patterns only appear during nighttime!

Moon Sequence: ???? → ???? → ???? → ???? → ????

Rewards: Vine Line and Vine Rune

Strategy: Use a Sundial item to control the time cycle, or wait until night naturally. If you die during the sequence, you can continue from where you left off during the same night, but the trial resets with each new day.

Room V Puzzle: The Reflection Pond

Location: (-4848, -1759, -9580) How to reach: Walk straight from Room III

The final puzzle features a small pond with the Hand Piece visible on the other side. To cross, you need to follow the pattern displayed on the ceiling/roof above the pond.

Alternative Strategy: Many players use Advanced Gliders to fly across the pond. This requires studying the map to identify safe landing zones for mid-air glider redeployment.

Rewards: Murky Thread and Water Rune

Once you’ve collected all five Runes, return to the main Temple Gates and place each Rune on its corresponding pedestal. The massive gate will open, granting you permanent access to the Mossjaw Rest area!

The Spawn Event: Timing is Everything

Unlike regular fish that spawn randomly, the Mossjaw only appears during specific server-wide events. Here’s what you need to know:

Event Name: “Lost Jungle — Elder Mossjaw Hunt”

How it works: When this event is active, a notification will appear at the top of your screen stating: “A Mossjaw Hunt has begun!”

Duration: These events occur randomly and last for a limited time. You need to be ready to act quickly when one starts.

Fast Travel: When the event is active, you can use the Temple Eye to teleport directly to the Temple Gates area, saving valuable time.

Pro Strategy: Many players camp in the Mossjaw Rest area during peak playing hours, waiting for events to start. Since you only need to solve the puzzles once, you can wait there indefinitely for the next hunt event.

Best Equipment for Catching Mossjaw

Catching the Mossjaw isn’t just about being in the right place at the right time—you need the right gear to overcome its massive penalties. Here’s what I recommend:

Recommended Fishing Rods

The Mossjaw applies severe penalties to your progress speed, so you need a high-tier rod to compensate. Here are the best options:

Sanguine Spire Rod: Currently the best rod in the game for rare fish catches
Luminescent Oath Rod: Excellent alternative with good rare fish bonuses
Seraphic Rod: Solid choice if you don’t have access to the other two

Why these matter: These high-tier rods provide better base stats and can handle the extreme penalties applied by the Mossjaw. Using anything less will make catching nearly impossible.

Essential Enchantments

The Mossjaw applies devastating progress speed penalties:

Mossjaw: -95% progress speed
Elder Mossjaw: -97% progress speed

To counter this, you need specific enchantments:

Primary Enchantments:

Steady Immortal: Provides significant progress speed boost
Mystical: Alternative to Steady Immortal with similar benefits

Secondary Enchantment:

Overclocked: Combine with either Steady Immortal or Mystical for maximum progress speed recovery

Enchanting Strategy: I recommend using Steady Immortal as your primary enchantment, paired with Overclocked. This combination gives you the best chance of filling the progress bar before the fish escapes.

Optimal Bait and Conditions

Based on extensive testing and research, here are the perfect conditions for catching Mossjaw:

Bait: Glowworm (non-negotiable—this is the only bait Mossjaw prefers)
Time: Night (Mossjaw only spawns during nighttime hours)
Weather: No preference (can be caught in any weather)
Season: No preference (available year-round)

Where to get Glowworm: Glowworms can be obtained in the Lost Jungle area. They spawn on trees and require playing a mini-game to collect them.

Luck Boosters

Given the extreme difficulty of catching Mossjaw (especially the Elder variant), you’ll want every advantage you can get:

Aurora Totem: Place this item to increase your luck and improve catch rates
Merlin NPC: Pay this NPC for additional luck bonuses
Advanced Gliders: While not directly affecting luck, these can help you navigate the temple area more efficiently

The Catching Process: Step-by-Step

Now that you have access to the Mossjaw Rest and the right equipment, here’s exactly how to catch the Mossjaw:

Step 1: Wait for the Event

Position yourself in the Mossjaw Rest area and wait for the “Lost Jungle — Elder Mossjaw Hunt” event to begin. You’ll see a notification at the top of your screen when it starts.

Step 2: Prepare Your Equipment

Ensure you have:

Your best rod (Sanguine Spire, Luminescent Oath, or Seraphic)
Proper enchantments (Steady Immortal/Mystical + Overclocked)
Glowworm bait equipped
Aurora Totem placed (optional but recommended)

Step 3: Cast Your Line

Stand near the pool in Mossjaw Rest and cast your line. The Mossjaw spawns in abundance during the event, so you shouldn’t have to wait long for a bite.

Step 4: Identify Your Catch

When you get a bite, pay attention to the indicator:

Regular indicator: You’ve hooked a standard Mossjaw (Exotic rarity)
Black exclamation mark (!): You’ve hooked the ultra-rare Elder Mossjaw (Secret rarity)

Step 5: The Reeling Battle

This is where the real challenge begins. The Mossjaw applies massive penalties to your progress bar:

For Mossjaw (Exotic):

Progress speed: -95%
Resilience: -30 (extreme difficulty)

For Elder Mossjaw (Secret):

Progress speed: -97%
Resilience: -200 (extreme difficulty)

Technique: Use a steady, consistent reeling motion. Don’t panic or reel frantically—this will only increase your chances of losing the fish. The key is patience and maintaining steady pressure.

Step 6: Land Your Catch

Once you’ve filled the progress bar (which will take significantly longer than normal fish), you’ll successfully land your Mossjaw. The game will display your catch with its rarity and any relevant statistics.

Common Mistakes to Avoid

After helping numerous players and learning from my own mistakes, here are the most common errors to avoid:

1. Wrong Equipment

Mistake: Attempting to catch Mossjaw with low-tier rods or wrong enchantments.
Solution: Invest in a Sanguine Spire, Luminescent Oath, or Seraphic Rod with proper enchantments. Anything less will likely result in failure.

2. Ignoring the Event

Mistake: Trying to catch Mossjaw outside of the “Lost Jungle — Elder Mossjaw Hunt” event.
Solution: Mossjaw ONLY spawns during these specific server events. Wait for the notification before attempting.

3. Wrong Bait

Mistake: Using any bait other than Glowworm.
Solution: Glowworm is the only bait Mossjaw responds to. Stock up before heading to the temple.

4. Wrong Time

Mistake: Trying to catch Mossjaw during daytime hours.
Solution: Mossjaw only appears at night. Use a Sundial or wait naturally for nighttime.

5. Panic Reeling

Mistake: Reeling frantically when the progress bar moves slowly due to penalties.
Solution: Maintain steady, consistent pressure. The penalties are severe—accept that it will take time and focus on technique rather than speed.

2026 Advanced Strategies for Elder Mossjaw

If you’re aiming for the ultimate prize—the Secret rarity Elder Mossjaw—you’ll need even more preparation and strategy:

1. Maximize Your Luck

Use multiple Aurora Totems if possible
Pay Merlin NPC for maximum luck bonuses
Consider fishing with others (some players report increased rare fish rates in groups)

2. Perfect Your Timing

Elder Mossjaw appears much less frequently than the standard variant
Be prepared for multiple event cycles before encountering one
Consider keeping track of event patterns to predict when they might occur

3. Master the Reeling Technique

The -97% progress speed penalty and -200 resilience make the Elder Mossjaw incredibly difficult to catch. Practice your technique on standard Mossjaw first to perfect your approach.

4. Prepare for Failure

Even with perfect preparation, the Elder Mossjaw has an extremely high escape rate. Don’t get discouraged—each attempt is valuable learning experience.
