Understanding the Plesiosaur Hunt System

Unlike regular fish that spawn consistently in specific locations, the Plesiosaur operates on a server-wide hunt event system similar to the Megalodon and Kraken encounters. This means you cannot simply camp at a location and expect to find it – you must be prepared for spontaneous server events that trigger the hunt.

The hunt mechanics work as follows: while you’re fishing or moving around in an active server, there’s a chance for a Plesiosaur Hunt event to trigger. When this happens, a notification appears at the top of your screen stating “A Plesiosaur prowls Tidefall…” This marks the beginning of a limited window where you can catch this elusive creature.

Important Note: The hunt ends immediately once someone catches the Plesiosaur, making speed and preparation crucial for success.

Step 1: Accessing Tidefall – The Foundation

Before you can even think about catching a Plesiosaur, you need to reach the Tidefall area. Here’s what you need to know:

Entering Tidefall

Locate the Underwater Opening in the Ocean area
Complete the “Tidefall: Lost Diver” quest from the Deep Diver NPC
Obtain Abyssal Tonic (costs 500 C$ or quest reward) to survive the pressure
Navigate through the extensive cave system to reach the central Tidefall area

The Tidefall area serves as a hub with four distinct sublocations, each hosting different hunt events. The Plesiosaur specifically appears in Tidefall Castle, but you’ll need to complete the Obelisk puzzle first to access it.

Step 2: Completing the Obelisk Puzzle

The Tidefall Castle gate remains locked until you solve the five Obelisk puzzles scattered throughout Tidefall. Each Obelisk requires specific fish or items as offerings. Here’s the complete breakdown:

Obelisk Color	Location	Required Offering
Gold	Collapsed Ruins	Goldwraith (from Crowned Ruins)
Purple	Tidefall (opposite shop)	Omnithal (from Sunken Reliquary)
Red/Orange	Tidefall (behind shop)	Pliosaur (from Collapsed Ruins hunt)
Sky Blue	Tidefall (by bridge/waterfall)	Reef Titan (from Coral Bastion)
White	Left of Tidefall waterfall	Sparkling Dripstone (trash item from Tidefall)

Pro Tips for Obelisk Completion:

Focus on one Obelisk at a time rather than trying to collect all requirements simultaneously
Stock up on Dripstone Collapse Totems (35,000,000 C$ each) to trigger hunt events more frequently
Join stable servers with active communities to increase hunt event frequency
Consider our Divine Secret Fish Fisch Guide for strategies on catching other rare hunt fish

Once you’ve completed all five Obelisks, the path to Tidefall Castle will open. You’ll need to glide over the water to reach the inner castle area where the Plesiosaur spawns.

Step 3: Optimal Gear Setup

Rod Selection

Your choice of fishing rod dramatically impacts your success rate with the Plesiosaur. Based on extensive testing and community feedback, here are the best options:

Fabulous Rod (Best choice) – Highest stats and control
Ruinous Oath Rod – Excellent balance of power and affordability
Rod of the Forgotten Fang – Strong alternative with good control

Essential Enchantments

Enchanting your rod is crucial for handling the Plesiosaur’s erratic behavior. Focus on these enchantments:

Control-enhancing enchantments to manage sudden direction changes
Luck-boosting enchantments to increase spawn chances
Stamina preservation enchantments for longer reeling sessions

Bait and Equipment

Sharkhead Bait (Plesiosaur’s favorite)
Quality Bait Crates for backup options
Super Flippers for better mobility in Tidefall

Step 4: Mastering the Hunt Event

Understanding Spawn Mechanics

The Plesiosaur Hunt has specific spawn conditions that affect your success rate:

Base spawn chance: 0.2% during server events
Forbidden Plesiosaur: 0.02% spawn chance (replaces regular variant)
Time-based bonuses: Higher chances at night
Weather multiplier: Foggy weather increases spawn rates
Season bonus: Winter season provides additional benefits

Hunt Event Strategy

Stay in one server rather than constantly hopping – stable servers have more consistent hunt events
Fish actively in Tidefall Castle area to increase server activity
Keep Dripstone Collapse Totems ready to manually trigger events
Position yourself near the castle pool for instant access when the hunt begins
Watch for the black exclamation mark indicating a Forbidden Plesiosaur

The Reeling Challenge

Plesiosaur fights are among the most challenging in the game. Here’s how to handle them:

Expect erratic movement patterns similar to other exotic fish
Maintain steady pressure without overcorrecting
Use your rod’s abilities wisely – don’t waste special moves
Stay calm during direction changes – panic leads to mistakes
Learn from failed attempts – each attempt teaches you the fish’s patterns

Step 5: Advanced Strategies and Pro Tips

Server Management

Choose servers with 10-15 active players for optimal hunt frequency
Avoid overcrowded servers where competition is too high
Build relationships with regular players for coordinated hunt efforts
Join the official Fisch Discord for real-time hunt notifications

Time and Weather Manipulation

Use private servers to control time and weather conditions
Wait for natural foggy weather in winter for maximum bonuses
Coordinate with friends to cover different time zones
Keep track of weather patterns in your preferred servers

Economy and Resource Management

Budget 50,000-100,000 C$ for a serious Plesiosaur hunting session
Invest in permanent upgrades like better rods rather than consumables
Sell excess rare fish to fund your hunting efforts
Consider trading for hard-to-get requirements like the Fabulous Rod

Understanding the Forbidden Plesiosaur

The Forbidden Plesiosaur represents the pinnacle of rare catches in Fisch. Here’s what makes it special:

Identification

Black exclamation mark appears over the fishing pool when hooked
Distinctive dark coloring compared to the regular variant
Divine Secret rarity classification
Significantly harder reeling challenge

Increased Difficulty

More aggressive movement patterns
Longer reeling duration
Higher failure rate even with optimal gear
Requires perfect timing and rod management

Common Mistakes to Avoid

Preparation Errors

Attempting without proper gear – don’t waste hunt events with weak rods
Ignoring weather conditions – foggy winter nights provide significant bonuses
Forgetting bait requirements – Sharkhead bait dramatically increases success rates
Neglecting enchantments – unenchanted rods struggle with exotic fish behavior

Hunt Event Mistakes

Server hopping too frequently – miss events while loading
Positioning too far from the spawn point – lose precious seconds traveling
Panicking during the reeling minigame – steady hands win catches
Giving up too early – some players catch it after dozens of attempts

Resource Management

Overspending on consumables – invest in permanent upgrades first
Ignoring other Tidefall content – build wealth through regular fishing
Not joining community servers – miss out on coordinated hunt efforts
Neglecting account progression – higher levels provide passive bonuses

Frequently Asked Questions

How long does it typically take to catch a Plesiosaur?

Most players report catching their first Plesiosaur after 10-50 hunt events, depending on gear, preparation, and luck. The Forbidden variant can take significantly longer due to its 0.02% spawn rate.

Can you catch multiple Plesiosaurs?

Yes! The Plesiosaur Hunt can trigger multiple times, allowing you to catch several for trading, collection purposes, or crafting multiple Requiem rods.

Is the Plesiosaur required for any specific quests?
