How to Get Plesiosaur & Pliosaur in Fisch (July 2026) Tidefall Update

The Plesiosaur and Pliosaur are two new Exotic fish introduced in the Fisch Tidefall update (version 1.67), available exclusively through hunt events in the new Tidefall location. Pliosaur spawns in the Collapsed Ruins during its hunt event, while Plesiosaur appears in Tidefall Castle after completing the Obelisk puzzle. Both require Shark Head bait, nighttime, foggy weather, and winter conditions for optimal catching chances.

Quick Reference

Fish	Location	Hunt Required	Best Rod	Best Bait	Best Conditions
Pliosaur	Collapsed Ruins	Yes	Blade of Glorp/Seraphic/Wind Elemental	Shark Head	Night, Foggy, Winter
Plesiosaur	Tidefall Castle	Yes	Fabulous Rod	Shark Head	Night, Foggy, Winter
Forbidden Plesiosaur	Tidefall Castle	Yes	Fabulous Rod	Shark Head	Night, Foggy, Winter

Overview of the Tidefall Update

The Tidefall update represents Fisch’s sixty-eighth major release, introducing an entirely new endgame area that expands the world significantly. This update brings four major hunt events: Plesiosaur Hunt, Reef Titan Hunt, Pliosaur Hunt, and Omnithal Hunt. These hunt-exclusive Exotic fish function as progression gates rather than simple collection items, creating a structured path through the new content.

The update introduces Tidefall as a sprawling underground cave system with six primary sublocations, each hosting unique fish and challenges. At its heart lies the Obelisk puzzle, a complex multi-step quest that gates access to the inner Tidefall Castle where the most prized catches await.

How to Access Tidefall?

Before attempting to catch either Plesiosaur or Pliosaur, you must first unlock the Tidefall area itself:

1. Navigate to coordinates 3224, 130, 847 using your Fisch GPS
2. Equip Water Bubble and Tidebreaker items – these are essential for entering the underwater cave system
3. Enter the Underwater Cave at approximately coordinates 3138, 132, 910
4. Use Advanced Oxygen to navigate through the underwater sections safely

The Tidefall area consists of multiple interconnected zones, including Collapsed Ruins, Coral Bastion, Sunken Reliquary, Crowned Ruins, and the central Tidefall hub where you’ll find various NPCs and merchants.

Complete Guide to Catching Pliosaur

Location and Hunt Mechanics

The Pliosaur spawns exclusively during the Pliosaur Hunt server event in the Collapsed Ruins area of Tidefall. Unlike regular fish, it never appears as a standard spawn and can only be caught when the dedicated hunt event is active.

Exact Location: Collapsed Ruins entrance at coordinates approximately 3150, -1050, 1270 (slight variations exist between sources, but all point to the same general area).

How the Hunt Works:

1. Stay in an active server and fish or move around normally
2. Watch for the hunt banner at the top of your screen announcing “Pliosaur has spawned”
3. Move immediately to the Collapsed Ruins area – timing is crucial as hunts have limited windows
4. Fish in the event pool and play the reeling minigame if you hook the Pliosaur

Optimal Setup for Pliosaur

Best Rods (in order of preference):

• Blade of Glorp
• Seraphic Rod
• Wind Elemental Rod
• Ruinous Oath (minimum recommended)
• Rod of the Forgotten Fang (minimum recommended)

Essential Conditions:

• Bait: Shark Head (non-negotiable for best results)
• Time: Night (use Sundial Totem to speed up time if needed)
• Weather: Foggy (use Smokescreen Totem to trigger fog)
• Season: Winter (use Smokescreen Totem to summon winter conditions)

Critical Enchantments: The Pliosaur applies a devastating -90% progress speed penalty, making enchantments essential:

• Swift – Increases progress speed
• Steady – Reduces erratic movement
• Immortal – Prevents rod breaking
• Blessed Song – Overall performance enhancement

Advanced Strategies

Server Management: Rather than server hopping, establish yourself in a stable, active server. Constantly switching servers increases your chances of missing hunt events. Use the waiting time to grind other Tidefall catches or farmable essences.

Preparation Checklist:

• Enchant your rod before the hunt begins
• Stock up on Shark Head bait (at least 20-30 for multiple attempts)
• Have Smokescreen and Sundial Totems ready
• Position yourself near Collapsed Ruins while waiting

The Ancestral Pliosaur: Occasionally, an Ancestral Pliosaur hunt event may trigger instead of the standard Pliosaur hunt. This variant is even rarer and offers unique rewards, though the catching strategy remains identical.

The Obelisk Puzzle Prerequisite

Unlike Pliosaur, Plesiosaur requires completing the extensive Obelisk puzzle first. This puzzle spans the entire Tidefall area and demands specific Exotic fish or items for each of the five Obelisks.

Obelisk Requirements :

Obelisk Color	Location	Required Item	How to Obtain
Gold	Collapsed Ruins	Goldwraith	Crowned Ruins hunt event
Sky Blue	Near bridge opposite waterfall	Reef Titan	Coral Bastion hunt event
Red/Orange	Behind Tidefall shop	Pliosaur	Collapsed Ruins hunt event
White	Near waterfall	Sparkling Dripstone	Trash item in Tidefall bestiary
Purple	Northeast of shop	Omnithal	Sunken Reliquary hunt event

Completing the Puzzle:

1. Catch all required fish during their respective hunt events
2. Visit each Obelisk in any order and offer the required item
3. Watch for the confirmation that each Obelisk has been satisfied
4. Access the unlocked path through the lush overgrown section near the waterfall
5. Glide over the water to reach Tidefall Castle

Location and Hunt Mechanics

Once inside Tidefall Castle, Plesiosaur spawns exclusively during the Plesiosaur Hunt server event. The mechanics mirror other major hunts but with the added challenge of the castle’s unique environment.

Castle Navigation: After completing the Obelisk puzzle, head toward the lush green covered area and glide over the water body to reach the inner castle grounds where Plesiosaur spawns.

Optimal Setup for Plesiosaur

Best Rods (in order of preference):

• Fabulous Rod (best in the game – highly recommended)
• Ruinous Oath
• Rod of the Forgotten Fang

Essential Conditions:

• Bait: Shark Head
• Time: Night (use Sundial Totem)
• Weather: Foggy (use Smokescreen Totem)
• Season: Winter (use Smokescreen Totem)

The Forbidden Plesiosaur Variant

During Plesiosaur hunts, you have a small chance to encounter the Forbidden Plesiosaur, a Divine Secret rarity variant. This ultra-rare version reveals itself with a black exclamation mark over the fishing pool when hooked.

Differences from Standard Plesiosaur:

• Rarity: Divine Secret (vs. Exotic for standard)
• Visual indicator: Black exclamation mark
• Increased difficulty: Significantly harder to reel in
• Greater rewards: Higher value and experience gains

Progression Chain and Late-Game Impact

Understanding how these fish fit into Fisch’s progression system is crucial for prioritizing your efforts:

The Complete Progression Path

1. Unlock Tidefall → Access the new area
2. Catch Pliosaur → Complete Red/Orange Obelisk requirement
3. Finish Obelisk Puzzle → Unlock Tidefall Castle
4. Catch Plesiosaur → Access high-tier crafting materials
5. Craft Requiem Rod → One of the best rods in the game

Strategic Importance

Pliosaur’s Role: Functions as a bottleneck for much of Tidefall’s content. A single successful catch unlocks access to the castle and, by extension, the Plesiosaur hunts and associated progression.

Plesiosaur’s Role: Serves as a key ingredient for crafting the Requiem rod and other high-tier equipment introduced in version 1.67. Both standard and Forbidden variants provide substantial experience and currency rewards.

Comparison with Other Prehistoric Fish

The Tidefall hunts build upon Fisch’s existing framework of prehistoric fish:

Plesiosaur vs. Mosasaurus:

• Location: Tidefall Castle vs. Ancient Isle
• Bait: Shark Head vs. Truffle Worm
• Difficulty: Similar hunt-only mechanics
• Progression: Plesiosaur feeds into rod crafting, Mosasaurus serves as endgame content

Pliosaur vs. Megalodon:

• Hunt Structure: Nearly identical server event mechanics
• Difficulty: Both require high-tier rods and optimal conditions
• Progression: Pliosaur gates content, Megalodon serves as achievement content

Common Mistakes to Avoid

Preparation Errors

1. Forgetting totems: Many players fail to bring Smokescreen and Sundial Totems, missing optimal conditions
2. Insufficient bait: Running out of Shark Head bait during a hunt event
3. Wrong rod choice: Using underpowered rods that can’t handle the -90% progress penalty

Timing Mistakes

1. Server hopping: Constantly changing servers increases missed hunt opportunities
2. Late arrival: Not reaching the hunt area quickly enough after the announcement
3. Wrong conditions: Fishing without meeting all weather/time/season requirements

Progression Mistakes

1. Ignoring other Obelisks: Focusing only on Pliosaur without collecting other required fish
2. Wasting hunt windows: Using Plesiosaur hunts for practice instead of serious attempts
3. Not enchanting rods: Attempting hunts without proper enchantment preparation

Pro Tips and Advanced Techniques

Server Strategy

Optimal Server Management:

• Join servers with 15-20 players for balanced event frequency
• Avoid completely empty servers (fewer events) or full servers (performance issues)
• Stay in one server for at least 30-45 minutes before considering a switch

Event Timing:

• Hunt events typically occur every 45-90 minutes
• Peak times (afternoon/evening) see more frequent events

Frequently Asked Questions

How often do Pliosaur and Plesiosaur hunt events occur?

Hunt events typically trigger every 45-90 minutes on active servers, but timing varies based on server population and activity levels. Peak gaming hours generally see more frequent events.

Can I catch Plesiosaur without completing the Obelisk puzzle?

No, Tidefall Castle is completely inaccessible until you complete all five Obelisk requirements. The Pliosaur is specifically needed for the Red/Orange Obelisk, making it a mandatory prerequisite.

What happens if I fail to catch the fish during a hunt event?

If you fail to reel in the fish or the hunt timer expires, you must wait for the next hunt event. There’s no penalty for failure beyond the lost opportunity.

Are the coordinates exact or approximate?

The provided coordinates (3150, -1050, 1270 for Pliosaur area) are approximate reference points. The exact spawn locations may vary slightly within the designated hunting zones.

Can I catch multiple Plesiosaurs or Pliosaurs during one hunt event?

Yes, you can catch multiple fish during a single hunt event window, but each requires successfully completing the reeling minigame individually.

Do the fish spawn in every server during hunt events?

Hunt events are server-specific, meaning they trigger individually on each server rather than across all servers simultaneously.

What’s the difference between standard and Forbidden Plesiosaur?

The Forbidden Plesiosaur is a Divine Secret rarity variant with a black exclamation mark indicator, significantly increased difficulty, and greater rewards compared to the standard Exotic version.

Can I use crab cages or other alternative methods to catch these fish?

No, Plesiosaur and Pliosaur can only be caught through traditional fishing during their respective hunt events. Alternative methods like crab cages won’t work.

How important are the weather and season conditions?

While not absolutely mandatory, meeting all optimal conditions (night, foggy weather, winter season) dramatically increases your catch rates and reduces the difficulty of the reeling minigame.

What should I do if I keep failing to catch these fish?

Focus on upgrading your rod, enchanting it properly, and practicing on easier Exotic fish. Also ensure you’re meeting all optimal conditions and consider joining a more active server.
