How to Catch Caustic Starwyrm in Fisch Roblox

If you have spent any serious time fishing in Fisch Roblox, you already know that secret fish are a different breed entirely. The Caustic Starwyrm is not something you stumble into by accident. It is one of the hardest catches in the game, locked behind a rare event, strict conditions, and unforgiving mechanics. Many players spend hours preparing only to miss their chance in a two minute window. That is why veteran players often streamline their setup early or use trusted platforms like PVPBank to buy Fisch fish or gear, letting them focus on execution instead of endless prep.

In this guide, I am going to walk you through exactly how to catch Caustic Starwyrm in Fisch Roblox, step by step. We will cover the location, Brine Storm mechanics, bait and timing, rod and enchantment setup, and real tips that actually improve your odds. This is written from experience, not theory.

What Is Caustic Starwyrm in Fisch Roblox

The Caustic Starwyrm is a Secret rarity fish introduced with the Brine Storm update. It belongs to the Brine Pool Bestiary and is widely considered the most valuable and difficult fish tied to that area.

What makes Caustic Starwyrm special is not just its rarity, but how many conditions need to line up perfectly for you to even have a chance at catching it. You are fighting low spawn rates, reduced lure speed, and a very short event timer all at once.

Quick facts about Caustic Starwyrm:

• Rarity: Secret

• Location: Brine Pool only

• Event requirement: Brine Storm

• Time: Night

• Favorite bait: Truffle Worm

• One of the hardest fish in Fisch Roblox

If you are missing even one requirement, it will not bite.

Caustic Starwyrm Location in Fisch Roblox

Brine Pool Location

The only place where Caustic Starwyrm can be caught is the Brine Pool, located in the Desolate Deep pocket area.

Exact Brine Pool coordinates:

• X -1720

• Y -175

• Z -3115

This area is completely inaccessible unless you travel through the Desolate Deep correctly.

How to Reach the Desolate Deep

To reach the Desolate Deep, head to the red buoy near Sunstone Island, also known as Point Nemo.

Buoy coordinates:

• X -791

• Y 142

• Z -3102

Equip Flippers and either an Advanced Oxygen Tank or Water Bubble. Dive straight down, navigate through the mine section carefully, and you will emerge inside the Desolate Deep.

From there, follow the tunnels until you locate the hidden entrance leading to the Brine Pool.

Veteran tip: Do this trip before rain starts. You do not want to be traveling when the event triggers.

Brine Storm Event Requirement Explained

You cannot catch Caustic Starwyrm without an active Brine Storm. This is non negotiable.

How the Brine Storm Works

The Brine Storm is a server wide event that:

• Can only occur during Rain

• Has a 1 percent chance to activate every 30 seconds

• Lasts exactly 2 minutes

• Changes the Brine Pool water color to teal

• Reduces lure speed and resilience by half

When the event ends, the water returns to green and Caustic Starwyrm becomes unavailable again.

How to Trigger the Brine Storm

You can wait for natural rain or force it using the Tempest Totem.

Tempest Totem location:

• Hidden underwater cave near Terrapin Island

• Coordinates: X 36, Y 135, Z 1946

Using the Tempest Totem triggers rain, giving the server repeated chances to spawn the Brine Storm.

Once you see the event announcement, stop everything and fish immediately.

Best Time and Bait for Caustic Starwyrm

This part is simple, but many players still mess it up.

Correct Conditions

• Time: Night only

• Bait: Truffle Worm

• Weather: Brine Storm active

• Season: No requirement

Using any bait other than Truffle Worm dramatically lowers your odds. Do not experiment here.

Best Rods for Catching Caustic Starwyrm

Fishing in the Brine Pool requires specific rods or enchantments. Without them, you cannot even cast properly.

Rods that work in the Brine Pool:

• Reinforced Rod

• Electric Guitar

• Tryhard Rod

• Bone Blade

• Oniriflax

• Any rod with Invincible Enchantment

Recommended Rods

From experience, the following perform best:

• Seraphic Rod

• Requiem Rod

These rods have strong base stats that help counter the Brine Storm debuffs.

Required Enchantments for Brine Storm Fishing

If you are not using a rod that naturally works in the Brine Pool, you must use the Invincible Enchantment. There is no workaround.

Best Secondary Enchantments

Because lure speed is cut in half during the event, enchantments are critical.

Top choices:

• Hasty

• Swift

• Breezed

• Momentum

These help offset the penalty and make secret fish realistically catchable within the short window.

Pro Tips to Catch Caustic Starwyrm More Consistently

This is where most guides fall short. Here is what actually helps.

• Camp the Brine Pool before rain starts

• Pre equip Truffle Worm before the event triggers

• Do not rod swap during the event

• Ignore other fish and focus only on Caustic Starwyrm

• Track night cycle timing carefully

• Accept that some events will fail no matter what

The Brine Storm is short. Hesitation costs attempts.

Common Mistakes Players Make

Avoid these and you already improve your odds.

• Showing up late to the Brine Pool

• Fishing during day instead of night

• Using the wrong bait

• Forgetting Invincible enchantment

• Trying to catch multiple fish types in one event

This event rewards discipline, not greed.

Can Caustic Starwyrm Be Caught Outside Brine Storm

No.

Caustic Starwyrm cannot be caught outside the Brine Storm Event and cannot be found anywhere else in Fisch Roblox. If the water is not teal, it will not spawn.

Is Caustic Starwyrm Worth the Effort

Yes, if you care about:

• Completing the Brine Pool bestiary

• Owning one of the rarest fish in the game

• Proving you can execute under pressure

This is a prestige catch. It is supposed to be hard.

Final Thoughts

Learning how to catch Caustic Starwyrm in Fisch Roblox is less about luck and more about preparation. You need the right location, the right timing, the right bait, and the right mindset. Even then, success is never guaranteed.
