Diamond Rod Fish It has become one of the most talked-about topics among Fish It Roblox players after the early January 2026 update was officially released. Diamond Rod comes as the newest fishing rod with performance above the Element Rod and is specifically designed to help players hunt rare fish and secret fish. To obtain it, players must complete a series of fairly long and challenging missions.

This update is officially confirmed through in-game Fish It Roblox content and various community guides, making Diamond Rod one of the most prestigious rewards available today.

What Is Diamond Rod Fish It?

Diamond Rod Fish It is a high-tier fishing rod introduced in the latest Fish It Roblox update. This rod offers high stability and more consistent chances when fishing for secret fish, making it a significant upgrade over the Element Rod. Unlike regular rods, Diamond Rod can only be obtained through a special quest and is not available for direct purchase.

How to Start the Diamond Rod Fish It Quest

To start the Diamond Rod Fish It quest, players must go to Fisherman Island and enter the Mutation Cellar marked with a diamond icon. Inside this area, find the NPC Diamond Researcher named Larry.

From this NPC, players can take the Diamond Research Quest. Once the quest is active, the full list of Diamond Rod missions will be unlocked and can be tracked through the quest menu.

Diamond Rod Fish It Mission List

1. Own an Element Rod

The first mission requires players to already have an Element Rod. Without this rod, the Diamond Rod quest cannot be continued. This is a mandatory requirement before proceeding to the next missions.

2. Catch a Secret Fish in Coral Reef

Players must catch a secret fish again in the Coral Reef area. Previously obtained secret fish do not count. One recommended target is the Eerie Shark, with a chance of around 1 in 250,000.

3. Catch a Secret Fish in Tropical Groove

In Tropical Groove, there is only one secret fish, the Great Whale, with a chance of around 1 in 950,000. Although it appears extremely rare, many players consider this area more efficient since it only contains one secret fish.

4. Bring a Mutated Gemstone

The next mission requires players to bring a Gemstone in its mutated form. Gemstones can be obtained from the Ocean, and using a Mutation Potion is highly recommended to speed up the process. After obtaining a mutated gemstone, return to Larry to exchange it.

5. Bring the Secret Lohness Monster

Lohness Monster is a secret fish from the Kohana area with a rarity of around 1 in 3,000,000. The good news is that players do not need to catch it again if it is already in their inventory. Simply take out the Lohness Monster and perform an exchange with Larry.

6. Catch 1,000 Fish with Perfect Throws

This is the most time-consuming mission in the Diamond Rod Fish It quest. Players must catch 1,000 fish using Perfect Throws. Non-perfect throws do not count. To make this easier, the Perfection enchant is highly recommended, as it automatically counts every throw as a perfect throw.

Tips to Complete the Diamond Rod Fish It Quest More Efficiently

To speed up progress, players are advised to focus on Tropical Groove first since it only has one secret fish. Use potions before fishing, find favorite spots that frequently produce secret fish, and combine the Perfection enchant with Secret Hunter if available. In addition, taking advantage of luck bonus events when servers are crowded can significantly improve success rates.

How to Get the Diamond Rod Fish It Reward

The Diamond Rod Fish It reward does not appear automatically after completing the final mission. Players must claim it by exchanging the quest with NPC Larry. Follow these steps:

1. Make Sure All Missions Are 100% Completed

Required missions include:

• Owning an Element Rod

• Catching the Coral Reef secret fish again

• Catching the Tropical Groove secret fish (Great Whale)

• Obtaining a Mutated Gemstone (must be mutated, not normal)

• Having the Lohness Monster (can be from an existing inventory)

• Catching 1,000 fish with Perfect Throws

If even one requirement is incomplete, the reward cannot be claimed.

2. Visit NPC Larry in Mutation Cellar

Location:

• Fisherman Island

• Enter Mutation Cellar

• Meet Diamond Researcher (Larry)

3. Perform Exchange / Turn In Quest

After all missions are complete:

• Open dialogue with Larry

• Select the exchange or turn in quest option

• The system will automatically verify all progress

If there are no errors, the Diamond Rod will immediately be added to your inventory.

4. No Crafting or Additional RNG Required

• No crafting required

• No gacha involved

• No additional secret fish needed

• The reward is 100% guaranteed after completing the quest

Why Many Players Fail to Get the Reward

Common reasons include:

• Old secret fish are assumed to count (they must be caught again)

• The Gemstone is not actually mutated

• Perfect Throw count is below 1,000 (tip: use the Perfection enchant)

• Lohness Monster is owned but not taken out during the exchange process

Additional Fish It Update January 2026

In addition to Diamond Rod Fish It, the latest Fish It update also introduces additional quests from multiple NPCs, new limited skins, a Christmas Cave with a longer opening duration, and a Home Island feature that can be activated after reaching 100 percent area index completion. These features make Fish It feel more dynamic and provide long-term goals for players.

Overall, Diamond Rod is not a rod that can be obtained quickly. However, the reward is well worth the effort. With proper planning and smart use of enchants and available events, players can complete the Diamond Rod quest more efficiently and in a more structured way.
