All Crafting Fish Locations in Heavyweight Fishing Roblox

Published 31 Aug 2026, 6:11 am · 3 min read

Trying to craft the best rods in Heavyweight Fishing but don’t know where to find all the required fish? There are three craftable rods to work toward: Sacred Bamboo, Heaven Piercer, and Pure Diamond.

Each one requires a different set of fish, and some of them only appear under specific weather conditions. Here’s where to find everything you need.

Sacred Bamboo Rod Fish Locations

Let’s start with the Sacred Bamboo Rod.

You’ll need four different fish to craft it:

• Nameless Octoparasite — Summoned using Nameless Bait.

• Reborn Puffer Beast — Caught on Frost Isle during Snowy weather.

• Ascended Perch — Found on Perch Isle.

• Mountain Fish — Caught on Mist Peak Isle.

The Nameless Octoparasite and Frost Beast require specific conditions or bait, so make sure you have the necessary bait before heading out.

Heaven Piercer Rod Fish Locations

Next is the Heaven Piercer Rod, which has 100 Power and is one of the major endgame rods.

You’ll need:

• Flying Fish Emperor

• Flying Fish Empress

• Heaven Piercer Turtle

• Rainbow Dragon Fish

Flying Fish Emperor & Empress

Both the Flying Fish Emperor and Flying Fish Empress can be caught on Perch Isle during Windy weather.

Since they share the same location and weather requirement, it’s a good idea to farm both at the same time rather than waiting for another weather cycle.

Heaven Piercer Turtle

The Heaven Piercer Turtle appears on Coconut Isle during Foggy weather.

Make sure you’re fishing there when the weather changes to fog if you’re specifically hunting for this fish.

Rainbow Dragon Fish

The Rainbow Dragon Fish is a little different.

Instead of relying on a particular weather condition, you need to summon it using Rainbow Bait.

So, make sure you’ve got the required bait ready before trying to farm this one.

Pure Diamond Rod Fish Locations

The other 100 Power endgame rod is the Pure Diamond Rod.

You’ll need four fish:

• Frost King Fish

• Frost Queen Fish

• Sanguin Fish

• Draconic Koi

Frost King Fish

The Frost King Fish can be caught on Frost Isle during Snowy weather.

If you’re already farming the Reborn Puffer Beast for the Sacred Bamboo Rod, you can take advantage of the same snowy weather cycle.

Frost Queen Fish

The Frost Queen Fish is summoned using Frost Bait.

Keep some Frost Bait ready if you’re working toward Pure Diamond.

Sanguin Fish & Draconic Koi

Both the Sanguin Fish and Draconic Koi can be found on Amber Isle during Blazing Sun weather.

This is another useful farming combination because you can work toward both crafting requirements during the same weather cycle.

Best Way to Farm the Crafting Fish

If you want to craft these rods without wasting time constantly traveling between islands, pay close attention to the weather.

Several required fish share the same conditions:

Perch Isle + Windy

• Flying Fish Emperor

• Flying Fish Empress

Frost Isle + Snowy

• Reborn Puffer Beast

• Frost King Fish

Amber Isle + Blazing Sun

• Sanguin Fish

• Draconic Koi

Whenever one of these weather conditions appears, try to collect everything you need before moving on.

For fish that require bait, such as the Nameless Octoparasite, Rainbow Dragon Fish, and Frost Queen Fish, make sure you have the appropriate bait prepared beforehand.
