The Mossy Core stands as one of the most elusive and sought-after materials in the game, essential for creating the legendary Elder Mossripper Rod. As a dedicated FISCH player myself, I’ve spent countless hours researching and testing the best methods to obtain this rare Secret item. In this comprehensive guide, I’ll walk you through everything you need to know about getting the Mossy Core, from unlocking the required areas to maximizing your chances during the special events.

What is Mossy Core in FISCH?

The Mossy Core is a Secret rarity item in FISCH that appears as a green ball with a type of green plate featuring leaves on top. This mystical item has been waiting from the depths of the trials, making it incredibly valuable for end-game progression. Its primary and most important use is in crafting the Elder Mossripper Rod, one of the best fishing rods available in FISCH that offers significant advantages for serious anglers.

Key Facts About Mossy Core:

Rarity: Secret
Primary Use: Crafting Elder Mossripper Rod
Obtainment Method: Special drop during Moss Jaw Hunt events
Location: Moss Rest area within Forgotten Temple
Drop Rate: Extremely low (hidden item)

Complete Step-by-Step Guide to Getting Mossy Core

Step 1: Reach the Lost Jungle

Before you can even think about obtaining the Mossy Core, you need to reach the Lost Jungle Island. This area is located behind Sunstone Island, and you’ll need to follow the in-game marker to locate it. Once you arrive at the Lost Jungle, head to coordinates (-2603, 161, -2190) to find an opening with a rope attached to the corner. Use this rope to enter the Forgotten Temple.

Step 2: Complete All 5 Forgotten Temple Trials

The Mossy Core can only be found in a specific, locked area called Moss Rest, which is located within the Forgotten Temple. You cannot simply walk in; you must earn access first by solving five separate puzzles scattered throughout the temple. Each puzzle you successfully solve will grant you one rune.

Here’s a complete breakdown of all five trials:

Trial I – Pattern Puzzle

Location: GPS coordinates (-5234, -1758, -9620)
Solution: Follow the pattern: Triangle → Square → Square → Triangle → Circle → Triangle → Square → Triangle → Circle
Reward: Poisonous Spearhead and Rune Glyph

Trial II – Flooding Parkour Challenge

Location: GPS coordinates (-4642, -1748, -10193)
Solution: Enter the small section marked with “II” on the wall. Use railings and platforms to reach the top as the area floods
Reward: Toxic Core and Toxic Rune

Trial III – Spike Navigation

Location: GPS coordinates (-5405, -1759, -10231)
Solution: Navigate carefully through spike-filled intersections following this path: Right → Left → Right → Left → Left → Left
Reward: Barbed Spearhead and Spike Rune

Trial IV – Moon Phase Trial

Location: GPS coordinates (-5172, -1759, -10329)
Solution: Pull vines adjacent to moon symbols in this order: ???? → ???? → ???? → ???? → ???? (Note: This can only be done at night)
Reward: Vine Line and Vine Rune

Trial V – Pond Pattern

Location: GPS coordinates (-4848, -1759, -9580)
Solution: Follow the pattern on the ceiling by walking the same path across the pond
Reward: Murky Thread and Water Rune

Step 3: Activate the Gate to Moss Rest

Once you have collected all five runes from the trials, return to the main Forgotten Temple door and place each rune on its corresponding pedestal. This will unlock the sealed gate that leads to the Moss Rest area where the Mossy Core can be obtained.

Step 4: Trigger the Moss Jaw Hunt Event

You cannot get the Mossy Core by simply fishing in Moss Rest at any time. The material only has a chance to drop during the Moss Jaw Hunt event. Here’s how to trigger it:

Locate the Sundial Totems: These are special interactive objects found within the Moss Rest area
Activate the Totems: Interact with the Sundial Totems multiple times in succession
Wait for the Event: After activating the totems correctly, the Moss Jaw will eventually spawn within the Moss Rest area, signaling that the hunt is active

Step 5: Fish for the Mossy Core

Once the Moss Jaw Hunt event is active, you can begin fishing for the Mossy Core:

Start Fishing: Cast your line into the pond within Moss Rest
Prepare for a Grind: The Mossy Core is a hidden item with an extremely low drop rate. This means you will likely need to catch many fish before it finally appears in your inventory
Use Optimal Conditions: While the Mossy Core can drop during any Moss Jaw Hunt, using better fishing rods and appropriate bait can help you catch more fish faster, increasing your overall chances

2026 Pro Tips for Successfully Obtaining Mossy Core

Preparation Tips

Clear Your Inventory: Before you start the Moss Jaw Hunt, ensure you have enough free space in your inventory. If your inventory is full, you risk losing the Mossy Core if it drops
Use Your Best Gear: While not confirmed to affect the drop rate directly, using a better rod can help you catch fish faster, allowing you to make more attempts per event and increasing your overall chances
Bring Plenty of Bait: Stock up on Glowworm bait, which is preferred by many fish in this area

Event Optimization

Server Hop: If the Moss Jaw Hunt isn’t triggering, try switching to different servers. Each server has its own event timing
Time Your Attempts: The Moss Jaw Hunt events seem to follow certain patterns. Many players report better success during specific time periods
Coordinate with Others: If playing with friends, you can take turns activating Sundial Totems to speed up the process

Persistence Strategies

Set Realistic Expectations: The Mossy Core has an extremely low drop rate, so be prepared for a long grind
Take Breaks: Don’t burn yourself out by fishing for hours without breaks. The drop rate won’t change, but your mental state will
Track Your Progress: Keep count of how many fish you catch during each event. This will help you understand the patterns and stay motivated

Common Mistakes to Avoid

1. Skipping Puzzle Preparation

Many players try to rush into Moss Rest without completing all five trials first. You cannot access the area without all five runes, so take the time to complete each puzzle properly.

2. Ignoring Event Mechanics

Some players fish in Moss Rest without triggering the Moss Jaw Hunt event, wondering why they’re not getting the Mossy Core. Remember, the item only drops during these special events.

3. Poor Inventory Management

I’ve seen countless players lose their Mossy Core because their inventory was full when it dropped. Always ensure you have plenty of free space before starting your fishing session.

4. Underestimating the Grind

The Mossy Core has an extremely low drop rate. Don’t expect to get it on your first or even tenth attempt. This is an end-game item that requires significant time and effort.
