Meeting the Diamond Researcher

Inside the Mutation Cellar, you’ll find Lary the Scientist, the Diamond Researcher NPC who holds the key to obtaining the Diamond Rod. Interact with him and select “Diamond Researcher Quest” to add this epic quest to your Main Quest section. You can track your progress by clicking the page icon at the top of your screen.

Complete Quest Requirements Breakdown 2026

1. Own All Elemental Rods

Before Lary will even consider helping you, you must prove your fishing prowess by owning all four Elemental Rods. These are high-tier rods that each require completing their own respective quests. The Elemental Rods serve as prerequisites, demonstrating that you’ve mastered Fish It’s core mechanics.

Elemental Rod Stats for Reference:

Luck: 1111%
Reel Speed: 130%
Weight: 900,000 kg

2. Catch Secret Fish at Coral Reefs

The Coral Reefs area, accessible by boat from Fisherman Island, hosts two different Secret Fish. The most notable is the Eerie Shark, with an extremely rare spawn chance of approximately 1 in 250,000.

Pro Tips for Coral Reefs:

Use Luck Potions before fishing sessions
Fish during Admin Abuse events for boosted rates
Consider AFK fishing with proper setup
Focus on areas with higher player activity for better spawn rates

3. Catch Secret Fish at Tropical Grove

Tropical Grove, located back-left from your spawn point next to Coral Reefs, contains only one Secret Fish: the Great Whale. Despite its staggering rarity of 1 in 950,000, many players prefer this location due to the single-target focus.

Tropical Grove Strategy:

This area also yields regular Rubies for mutation
Use Secret Hunter enchant if available
Combine with Luck Potions for maximum effectiveness
Find your “favorite spot” and stick with it consistently

4. Obtain a Mutated Gemstone Ruby

Rubies spawn in three locations: Tropical Grove, Lost Isle Treasure Room, and the Ocean. However, Lary specifically requires a MUTATED version. Use a Mutation Potion on any Ruby you catch, or rely on RNG for natural mutation (not recommended).

Mutation Process:

Catch any regular Ruby
Apply Mutation Potion (100% success rate)
Confirm the gemstone shows “Mutated” in its description
Return to Lary for the exchange

5. Catch the Lochness Monster

The legendary Lochness Monster exclusively spawns at Kohana Island, recognizable by its prominent volcano. With a spawn rate of 1 in 3,000,000, this is one of the rarest catches in the game.

Lochness Monster Tips:

Fish consistently at Kohana Island
Use your best luck-boosting equipment
Take advantage of server-wide luck events
If you already own one from previous catches, you can use that (no need to recatch)

6. Master 1,000 Perfect Throws

This requirement often proves the most time-consuming aspect of the Diamond Rod quest. Every cast must be executed with perfect timing to count toward your progress.

Perfect Throw Strategy:

Recommended Enchant: Perfection (automatically counts every throw as perfect)
Alternative: Practice timing until you can consistently hit perfect throws
Best Locations: Areas with high fish spawn rates
Tracking: Monitor your progress in the quest menu

Advanced Strategies and Tips

Optimal Quest Order

Based on community feedback and success rates, here’s the most efficient order to complete Diamond Rod requirements:

Level Up to 5 (Quick completion)
Obtain Elemental Rods (Medium-term goal)
Mutated Ruby (Can be done alongside other tasks)
Lochness Monster (If already owned, skip to step 5)
1,000 Perfect Throws (Use Perfection enchant)
Coral Reefs Secret Fish (Two targets, better odds)
Tropical Grove Secret Fish (Save for last, single target)

Enchant Recommendations

For the Diamond Rod itself, the community agrees on these optimal enchantments:

Mutation Hunter III: Essential for mutated catches
Leprechaun II: Boosts luck and rare find rates

During the quest, prioritize these enchants:

Perfection: For the 1,000 perfect throws requirement
Secret Hunter: Increases secret fish spawn rates
Luck Boost: Standard for all rare fishing activities

Common Pitfalls to Avoid

Many players fail to obtain the Diamond Rod due to these common mistakes:

Using Old Secret Fish: Previously caught secret fish don’t count – you must catch new ones
Non-Mutated Gemstones: Regular Rubies won’t be accepted
Perfect Throw Count: Ensure you reach exactly 1,000 (use Perfection enchant)
Lochness Monster Exchange: Must have the monster equipped during the exchange process
Incomplete Quest Tracking: Regularly check your progress in the quest menu

Claiming Your Diamond Rod

Once you’ve completed all six requirements, return to Lary in the Mutation Cellar. The process isn’t automatic – you must:

Verify 100% Completion: Check that all quest requirements show as complete
Initiate Dialogue: Speak with Lary and select “Exchange Items” or “Turn In Quest”
System Verification: The game will automatically validate your progress
Receive Diamond Key: Upon successful verification, you’ll receive the Diamond Key
Access Secret Passage: Use the Diamond Key on the potions shelf to reveal a hidden staircase
Claim Your Reward: Descend the stairs and collect the Diamond Rod from its pedestal
