The Deep Sea Quest in Fish It represents the ultimate end-game challenge for dedicated anglers. This multi-stage underwater questline takes place at the mysterious Lost Isle and rewards successful fishers with the Ghostfin Rod, the strongest fishing rod in the entire game. But completing this quest requires serious preparation, substantial coin investment, and hours of dedicated grinding.
In this comprehensive guide, we’ll walk you through every step of the Fish It Deep Sea Quest, from purchasing essential diving gear to catching the elusive Secret fish that blocks many players from completing this challenging questline.
What Is the Deep Sea Quest?
The Deep Sea Quest is an end-game questline located at Lost Isle, an underwater location that requires special equipment to access safely. This quest challenges players to catch hundreds of rare fish, multiple mythic fish, at least one secret fish, and accumulate one million coins before rewarding them with the coveted Ghostfin Rod.
Unlike simple fetch quests or short grinding sessions, the Deep Sea Quest represents a serious time investment that can take anywhere from several days to multiple weeks depending on your luck with rare fish spawns and your fishing rod quality.
Why Complete the Deep Sea Quest?
The primary reward for completing the Deep Sea Quest is the Ghostfin Rod, widely recognized as the strongest and most powerful fishing rod in Fish It. This exceptional rod features superior stats across all categories including luck, control, speed, and resilience, making every other rod in the game feel inferior by comparison.
Beyond the Ghostfin Rod itself, completing this quest demonstrates mastery of Fish It’s core mechanics and proves you’ve reached true end-game status. The sense of accomplishment from finally catching that secret fish after hours of grinding is unmatched by any other achievement in the game.
Prerequisites: What You Need Before Starting
Before attempting the Deep Sea Quest, you’ll need to prepare several crucial items and reach certain progression milestones:
Diving Gear: Essential Equipment
The most critical requirement for accessing Lost Isle is Diving Gear, which prevents instant death when diving to the underwater location. Without this equipment activated, you’ll die immediately upon submerging to the depths where Lost Isle exists.
Where to purchase: Westle Utility Shop on Fisherman Island (next to the fish seller and potion shop)
Cost: 75,000 coins
How to activate: Equip the diving gear from your inventory and activate it until you see the confirmation message “Diving Gear is On”
This represents a substantial coin investment, so make sure you’ve saved enough through fishing and selling catches before attempting to reach Lost Isle.
High-Quality Fishing Rod
While technically possible to complete the Deep Sea Quest with lower-tier rods, having a strong fishing rod dramatically reduces the time required. The quest demands catching three hundred rare or epic fish, three mythic fish, and one secret fish, making rod quality crucial for success.
Recommended rods:
- Ares Rod with Leprechaun II enchantment (best for secret fish)
- Astral Rod or higher with luck-boosting enchantments
- Any rod with at least one hundred percent luck stat
The better your rod’s luck and control statistics, the faster you’ll complete the quest requirements.
Adequate Coin Reserve
Beyond the seventy-five thousand coins needed for diving gear, you should have additional funds for:
- Purchasing better rods if needed
- Buying bait and bobbers
- Replacing lost equipment
- General progression expenses
Budget at least one hundred thousand coins total before starting the quest to ensure you’re not grinding coins while trying to catch rare fish.
Reliable Boat
Traveling to Lost Isle requires a boat capable of making the journey from Fisherman Island. While the basic fifty-gold boat technically works, investing in a faster, more reliable boat improves your quality of life significantly.
How to Reach Lost Isle
Lost Isle’s underwater location makes it one of the most difficult areas to find in Fish It. Follow these detailed directions to reach this hidden destination:
Step One: Depart From Fisherman Island
Spawn your boat at Fisherman Island and prepare for the journey. Make sure your diving gear is equipped and ready to activate before departing.
Step Two: Navigate to Lost Isle Location
From the main island, sail left into the open ocean. You’ll pass two large, distinctive rock formations that serve as landmarks. Continue sailing in this direction until you see the Lost Isle marker appear on your screen.
The journey takes several minutes, so be patient and watch for the location indicator that signals you’re approaching the correct area.
Step Three: Dive to the Underwater Structure
Once you reach the Lost Isle marker, activate your diving gear if you haven’t already. Dive straight down into the depths until you spot the underwater structure below. This ancient-looking building contains multiple rooms and air pockets where you can breathe safely.
Enter the structure through any of the available openings. Inside, you’ll find oxygen safe zones where your air meter refills, allowing you to explore without constantly returning to the surface.
Deep Sea Quest Requirements and Stages
The Deep Sea Quest consists of four distinct requirements that must be completed to unlock the Ghostfin Rod. Understanding each stage helps you plan your grinding strategy effectively.
Stage One: Catch 300 Rare or Epic Fish
The first and most time-consuming requirement involves catching three hundred fish of rare or epic rarity. This stage tests your patience and persistence more than any other part of the quest.
Best location: Treasure Room (lowest level of Lost Isle)
Strategy: The Treasure Room offers the highest concentration of rare and epic fish spawns in the entire Lost Isle area. Set up camp here and fish continuously, selling your catches periodically to make room for more.
Time estimate: Ten to twenty hours of active fishing depending on your rod quality and luck stat
Tips for efficiency:
- Use bobbers that increase luck to boost rare fish spawn rates
- Equip rods with high luck percentages
- Consider using luck-boosting enchantments like Leprechaun II
- Fish during in-game events that increase rare fish spawns
- Take breaks to prevent burnout during this extended grind
Stage Two: Catch 3 Mythic Fish
After completing the rare and epic fish requirement, you’ll need to catch three mythic fish. Mythic fish spawn much less frequently than rare or epic variants, making this stage significantly more challenging despite the lower quantity requirement.
Best location: Sisyphus Statue room
Strategy: The Sisyphus Statue area features multiple excellent fishing spots with decent mythic spawn rates. Rotate between different positions around the statue to maximize your chances.
Optimal fishing positions:
- Directly in front of the Sisyphus Statue
- Behind the statue base
- Rocks near the entrance
- Left-side rock formation
Time estimate: Five to fifteen hours depending on luck
Tips for success:
- Server hop if you spend multiple hours without catching a mythic
- Use your absolute best fishing rod for this stage
- Equip maximum luck-boosting equipment
- Fish during night or special weather events that boost spawn rates
- Be patient as mythic catches are heavily RNG-dependent
Stage Three: Catch 1 Secret Fish
This single requirement represents the most challenging obstacle in the entire Deep Sea Quest. Secret fish are the rarest catches in Fish It, with spawn rates so low that some players spend weeks attempting to catch just one.
Best location: Sisyphus Statue room (same as mythic fish)
Strategy: There’s no skill-based strategy for secret fish beyond maximizing your luck stat and grinding persistently. The catch is entirely RNG-based, meaning even perfectly equipped players can experience terrible luck streaks.
Time estimate: One day to three weeks (seriously)
Tips for maintaining sanity:
- Accept that secret fish catches are purely luck-based
- Set realistic daily fishing goals rather than obsessing over the catch
- Server hop every three to four hours if you’re not getting results
- Use the Ares Rod with Leprechaun II enchantment for maximum luck
- Rotate between the different fishing spots around the statue
- Take regular breaks to prevent complete burnout
- Remember that persistence eventually wins over bad RNG
Mental preparation: Many players report spending ten to twenty hours at the Sisyphus Statue before catching their secret fish. Some unlucky players exceed forty hours of grinding. Prepare yourself mentally for a potentially lengthy wait.
Stage Four: Accumulate 1,000,000 Coins
The final requirement involves earning one million coins through any means available in Fish It. The good news is that this requirement progresses naturally as you complete the other quest stages.
Strategy: By the time you catch three hundred rare and epic fish, three mythics, and one secret fish, you’ll have earned most or all of the required coins through normal gameplay.
Additional coin sources if needed:
- Sell all your caught fish regularly
- Complete daily quests for bonus coins
- Fish in high-value locations between Lost Isle sessions
- Use coin-multiplier potions if available
Most players complete this requirement without dedicated grinding since the fish-catching stages generate substantial income.
Best Fishing Spots at Lost Isle
Lost Isle contains multiple distinct fishing areas, each with different spawn rates and fish pools. Understanding which locations excel for specific quest requirements maximizes your efficiency.
Treasure Room: Rare and Epic Fish Paradise
The Treasure Room occupies the lowest level of the Lost Isle structure and features the best spawn rates for rare and epic fish in the entire game. This large, treasure-filled chamber provides ample space and consistently produces the catches you need for stage one.
Why it’s optimal:
- Highest rare fish spawn concentration
- Excellent epic fish spawn rates
- Multiple fishing spots in one convenient room
- Safe oxygen zones throughout
- Easy to set up and grind for extended sessions
Spend the vast majority of your stage-one grinding time here. The consistent rare and epic spawns make this location irreplaceable for efficient quest completion.
Sisyphus Statue: Mythic and Secret Fish Zone
The Sisyphus Statue room serves as the primary hunting ground for mythic and secret fish. This atmospheric chamber features a large statue surrounded by rocks and water, creating multiple distinct fishing positions with varying spawn characteristics.
Key fishing positions:
In Front of the Statue: The most popular spot, directly facing the imposing Sisyphus statue. Many players report their mythic catches from this position.
Behind the Statue: Less crowded and potentially offering different spawn pools than the front position. Some players swear by this spot for secret fish.
Entrance Rocks: The rock formations near the room’s entrance provide alternative casting angles and potentially different RNG seeds.
Left-Side Formation: The leftmost rock area offers a more isolated fishing experience with comparable spawn rates.
Rotation strategy: Spend thirty minutes at each position, then rotate to a new spot. This prevents stagnation and may help trigger different RNG outcomes for rare spawns.
Other Lost Isle Areas
While the Treasure Room and Sisyphus Statue room represent the optimal grinding locations, Lost Isle contains several other chambers worth exploring:
- Entry corridors with basic fish spawns
- Side chambers with moderate rare fish rates
- Hidden alcoves that some players claim offer better luck
However, for maximum efficiency, focus your efforts on the two main locations outlined above.
Optimal Rod and Enchantment Setup
Your equipment choices dramatically impact how quickly you complete the Deep Sea Quest. Here’s the ideal setup for each quest stage:
For Rare and Epic Fish (Stage One)
Primary rod choice: Any rod with one hundred percent or higher luck stat
Best enchantments:
- Leprechaun II: Plus fifty percent luck for maximum rare spawns
- Empowered I: Plus twenty percent luck and ten percent speed
- Momentum: Builds luck stacks over successful catches
Bait recommendations:
- Truffle Worm for maximum effectiveness
- Night Crawler for budget-conscious grinding
- Any luck-boosting bait you can afford in bulk
For Mythic Fish (Stage Two)
Primary rod choice: Ares Rod or your highest-luck rod available
Best enchantments:
- Leprechaun II: Essential for mythic spawn rates
- Cursed I: If focusing solely on mutations and mythics
- Quantum: For bonus catch value while grinding
Bait recommendations:
- Truffle Worm exclusively if possible
- Save your best bait for this stage
- Consider stacking luck potions during fishing sessions
For Secret Fish (Stage Three)
Primary rod choice: Ares Rod with Leprechaun II (widely considered the absolute best combination)
Best enchantments:
- Leprechaun II is mandatory, no other enchantment comes close
- Secondary enchants matter less than maximizing base luck
Bait recommendations:
- Truffle Worm only, no compromises
- Stack every luck buff available in the game
- Use luck potions during extended grinding sessions
- Consider timing your fishing with in-game events that boost spawn rates
The secret fish catch is entirely luck-based, so maximizing your luck stat through every available method is essential.
Advanced Deep Sea Quest Strategies
Beyond basic grinding, these advanced techniques can significantly improve your quest completion speed:
Server Hopping Strategy
If you spend three to four hours at the Sisyphus Statue without catching a mythic or secret fish, server hop to refresh the RNG seed. Different servers may have different spawn patterns, and changing servers occasionally prevents wasting time in an unlucky server instance.
How to server hop effectively:
- Leave your current game completely
- Rejoin Fish It from the Roblox page
- You’ll spawn in a different server with fresh RNG
- Return to Lost Isle and resume fishing
- Repeat if necessary after another extended session
Fishing Position Rotation
Rather than camping one spot indefinitely, rotate between the various fishing positions around the Sisyphus Statue every thirty to sixty minutes. This rotation may help trigger different RNG outcomes and prevents the psychological monotony of fishing from a single spot for hours.
Optimal Time Management
Break your Deep Sea Quest grinding into manageable sessions rather than marathon attempts:
- Two-hour focused sessions with breaks prevent burnout
- Fish during your peak alertness times for better perfect catches
- Set daily goals (fifty rare fish, one hour at statue, etc.)
- Celebrate small milestones to maintain motivation
Community Resources and Trading
Join the official Fish It Discord and Trello communities to:
- Learn about current spawn rate events
- Get real-time tips from players currently completing the quest
- Find grinding partners for motivation
- Stay updated on game changes that might affect quest completion
- Trade for items or bobbers that boost your chances
Combining Quest Stages
Once you reach the Sisyphus Statue for mythic and secret fish grinding, you’ll naturally earn substantial coins from selling your catches. Use these earnings to:
- Purchase better equipment between sessions
- Upgrade to stronger rods if needed
- Stock up on premium bait for future grinding
- Progress toward the one million coin requirement
Common Deep Sea Quest Mistakes
Avoid these pitfalls that slow down quest completion or waste valuable resources:
Starting Without Proper Preparation
Many players rush to Lost Isle without adequate coins, good rods, or proper bait. This leads to inefficient grinding and frustration when progress comes slowly. Prepare thoroughly before beginning the quest.
Using Suboptimal Equipment
Attempting the quest with low-tier rods and no enchantments dramatically extends completion time. Invest in proper equipment before starting, as the time saved more than justifies the coin expense.
Ignoring the Treasure Room
Some players try grinding rare and epic fish at the Sisyphus Statue instead of the Treasure Room. The statue area has significantly lower rare spawn rates, making this approach inefficient.
Giving Up Too Early on Secret Fish
The secret fish is genuinely rare, and bad RNG streaks are normal. Many players abandon the quest after a few unlucky days, only to regret it later. Persistence is absolutely essential for this stage.
Fishing Without Breaks
Marathon grinding sessions without breaks lead to burnout and reduced efficiency. Take regular breaks to maintain focus and motivation throughout the lengthy quest.
Not Server Hopping When Stuck
Stubbornly staying in an unlucky server wastes hours of potential progress. If you’re not seeing results after several hours, hop to a fresh server with new RNG.
Troubleshooting Common Issues
Dying Repeatedly at Lost Isle
If you keep dying when diving to Lost Isle:
- Verify diving gear is equipped AND activated
- Check that you have enough air to reach the structure
- Enter the building through the most visible entrance
- Swim quickly to an oxygen safe zone once inside
Can’t Find the Treasure Room
The Treasure Room is on the lowest level of Lost Isle. Swim down through the structure, following corridors downward until you reach the large room filled with treasure and multiple fishing spots.
Rare Fish Not Spawning
If rare fish seem exceptionally uncommon:
- Check your rod’s luck stat
- Equip luck-boosting enchantments
- Use better bait like Truffle Worm
- Consider server hopping
- Verify you’re fishing in the Treasure Room
No Mythic or Secret Fish After Many Hours
Unfortunately, this is normal. Mythic and especially secret fish have extremely low spawn rates. Continue grinding, server hop periodically, and maintain patience. The catch will eventually come.
Running Out of Coins During Quest
If you’re running low on coins:
- Sell all caught fish regularly
- Take breaks to fish at Kohana Volcano for quick money
- Complete daily quests for bonus coins
- Consider selling unused equipment or items
How Long Does the Deep Sea Quest Take?
Quest completion time varies dramatically based on luck and preparation:
Stage One (300 Rare/Epic Fish): Ten to twenty hours of active fishing
Stage Two (3 Mythic Fish): Five to fifteen hours depending on RNG
Stage Three (1 Secret Fish): One day to three weeks (highly variable)
Stage Four (1,000,000 Coins): Completes naturally during other stages
Total estimated time: Twenty to one hundred hours spread across multiple real-world days or weeks
The secret fish requirement creates the most time variance. Some lucky players catch it within hours, while unlucky players may spend forty-plus hours grinding before success.
Is the Deep Sea Quest Worth Completing?
For dedicated Fish It players, absolutely yes. The Ghostfin Rod represents the pinnacle of fishing equipment and provides a massive advantage for all future fishing activities. The bragging rights and sense of accomplishment also make the grind worthwhile.
However, casual players who don’t enjoy extended grinding sessions may find the quest tedious and frustrating. Evaluate your play style and commitment level before investing heavily in this challenging questline.
After Getting the Ghostfin Rod
Once you complete the Deep Sea Quest and claim your Ghostfin Rod, you’ve essentially “beaten” Fish It’s end-game content. From this point, you can:
- Collect every fish species in the game
- Hunt for rare mutations and shiny variants
- Help other players complete their Deep Sea Quest
- Farm coins and rare fish more efficiently than ever
- Complete any remaining achievements or challenges
- Experiment with different rod enchantments and strategies
The Ghostfin Rod transforms every fishing activity, making catches easier and more profitable throughout the entire game.
Conquer the Deep Sea Quest
The Fish It Deep Sea Quest represents one of the most challenging and rewarding questlines in Roblox fishing games. While the grind is substantial and the secret fish requirement tests your patience, the Ghostfin Rod reward makes every hour of effort worthwhile.
