What is the Mossy Core?

The Mossy Core is a Secret-rarity material in FISCH that appears as a glowing green orb with mossy plate formations. This rare item serves as a crucial crafting component for the Elder Mossripper Rod, widely considered one of the best fishing rods in the game. Due to its extremely low drop rate and the complex process required to access its location, the Mossy Core is highly sought after by dedicated FISCH players looking to maximize their fishing capabilities.

Unlike most rare materials in FISCH, the Mossy Core cannot be appraised and has no purpose other than crafting the Elder Mossripper Rod. This specialization makes it a true end-game item that players specifically target once they've progressed through most other content.

Step 1: Gaining Access to Moss Rest

Before you can even attempt to obtain the Mossy Core, you must first gain access to the Moss Rest area. This involves a multi-step process that tests your puzzle-solving skills and patience.

Locating the Forgotten Temple

The Forgotten Temple is hidden within the Lost Jungle area of FISCH. To reach it:

1. Navigate to Lost Jungle: Use your GPS and head to coordinates -3080, 140, -1125
2. Find the Temple Entrance: Pass the Spear Crafting area and cross the bridge
3. Climb the Ledge: Head up the ledge and walk right toward the small cliff
4. Use the Rope: Interact with the rope by pressing 'E' to descend into the temple

Pro Tips Before Starting:

• Talk to the Jungle Adventurer NPC: Before attempting any puzzles, speak with the Jungle Adventurer NPC and obtain the Temple Eye. This item allows you to return to the Temple Gate checkpoint if you die during puzzle attempts
• Clear Your Inventory: Ensure you have sufficient inventory space for runes and other items you'll collect
• Bring Advanced Glider: Some puzzles require mobility, and having an Advanced Glider can be helpful

1. Glyph Rune (Room I)

Opening the Forgotten Temple Gate

Once you've collected all five runes, return to the Temple Gate checkpoint and place them on their respective pedestals:

• Light Grey Rune (Left side, Left): Glyph Rune
• Dark Grey Pedestal (Left side, Middle): Spiked Rune
• Light Green (Left Side, Right): Toxic Rune
• Dark Green Pedestal (Right Side): Vine Rune
• Blue Pedestal (Right Side): Water Rune

The moment you place the final rune, the massive door will open, granting you access to Moss Rest. Walk through the door, descend the steps, and you'll find a large pool where the Moss Jaw Hunt event takes place.

Step 2: Triggering the Moss Jaw Hunt Event

Unlike other rare materials in FISCH, the Mossy Core doesn't drop from regular fishing. Instead, it only appears as a potential drop during the special Moss Jaw Hunt event. Here's how to trigger this event:

Using Sundial Totems

The Moss Jaw Hunt event is triggered by interacting with the Sundial Totems located in the Moss Rest area. Follow these steps:

1. Locate the Sundial Totems: These are typically found around the pool area in Moss Rest
2. Interact Multiple Times: You may need to activate the totems several times in succession
3. Wait for the Moss Jaw: After successful activation, the Moss Jaw will spawn in the area
4. Event Confirmation: When the Moss Jaw appears, the Moss Jaw Hunt event becomes active

Understanding Event Mechanics

The Moss Jaw Hunt event has specific mechanics that players should understand:

• Time-Limited: The event doesn't last indefinitely, so you must act quickly once triggered
• Exclusive Drops: Only during this event can you obtain the Mossy Core
• Increased Activity: The Moss Jaw becomes more active and catchable during the event
• No Guaranteed Drops: Even during the event, the Mossy Core drop rate remains extremely low

Best Practices for Event Triggering

To maximize your chances of successfully triggering and utilizing the Moss Jaw Hunt event:

• Server Timing: Try triggering the event during off-peak hours when fewer players are competing
• Multiple Attempts: Be prepared to trigger the event multiple times, as success isn't guaranteed
• Preparation: Have all your fishing equipment ready before triggering the event
• Team Coordination: Consider working with other players to trigger and maintain the event

Step 3: Fishing for the Mossy Core

Once the Moss Jaw Hunt event is active, you can begin fishing for the Mossy Core. This is where patience truly becomes a virtue, as the drop rate is exceptionally low.

Fishing Mechanics in Moss Rest

The Moss Rest pool shares its bestiary with the Lost Jungle, but with some important distinctions:

• Exclusive Content: Only Exotic and Secret rarity fish from this bestiary can be caught in Moss Rest
• Event-Specific Drops: The Mossy Core only appears as a hidden item drop during the Moss Jaw Hunt
• Special Conditions: Similar to how the Kraken works in other areas, special conditions must be met

Optimal Fishing Strategy

To maximize your chances of obtaining the Mossy Core:

• Use Your Best Rod: While not confirmed to directly affect drop rates, better rods help you catch fish faster, allowing more attempts per event
• Target Mossjaw: Focus on catching Mossjaw during the event, as this seems to be the most effective method
• Clear Inventory Space: Ensure you have plenty of free inventory slots to avoid missing the drop
• Persistent Fishing: Be prepared to catch numerous fish before the Mossy Core appears
• Event Duration: Make the most of the limited event time by fishing continuously

Drop Rate Information

The exact drop rate for the Mossy Core is not officially disclosed by the developers, but based on community reports and game mechanics:

• Extremely Low: Considered one of the rarest drops in the game
• Hidden Item: Functions as a hidden item rather than a direct fish catch
• Event-Dependent: Only available during Moss Jaw Hunt events
• Multiple Attempts Required: Most players report needing numerous event cycles to obtain it

Common Mistakes to Avoid

When farming for the Mossy Core, avoid these common pitfalls:

• Full Inventory: Nothing worse than missing the drop due to lack of space
• Poor Timing: Triggering the event when you don't have time to fish extensively
• Wrong Location: Fishing outside Moss Rest or when the event isn't active
• Impatience: Giving up too quickly; this requires significant time investment
• Ignoring Preparation: Not having the right equipment or inventory space ready
