The Scavenger Rod can be acquired from completing Dr. Crookspine's three-part quest at the Laboratory on Rosslit Bay. The Meteoric Rod can be acquired from completing Astral Matthew's quest in the Northern Expedition. The Rod of Singularity is the hardest of the three, which involves complete a questline from the Abyssal Zenith NPC, then catch five secret fish from five hidden areas across the map and return them to Merlin.
The Astral update added four new rods to Fisch, three of which can be obtainable through quests. The Scavenger Rod, Meteoric Rod, and Rod of Singularity. Each requires a different quest chain from a different NPC, and the Rod of Singularity in particular requires discovering hidden fishing portals across five separate locations. So, this complete guide walks through every quest step and location for all three.
How Do You Get the Scavenger Rod in Fisch?
Head to the oil rig off the coast of Rosslit Bay, enter the building at the top, and turn right to find Dr. Crookspine. Talk to him to begin a three-part quest chain. The Scavenger Rod is your reward upon completing all three.
Quest 1 - Two Silver Rusty Bolts
Fish in the Mine Shaft zone with the Titanium Rod and Garbage Bait. The Rusty Bolt is a low rarity item but requires the Silver mutation. Equip Mutated Sharky or use a Mutation Totem and appraise to get the Silver mutation.
TIP: The Toxin Burst rod works well here since extra catches from its passive increase how quickly you accumulate Rusty Bolts.
Quest 2 - Five Scrap Metal
Fish in The Depths during daytime with any rod and Garbage Bait. Scrap Metal is low rarity so it comes up frequently. The Toxin Burst, Soul Reaper, Olympian Godbreaker, or any fast-catching rod all work here.
Quest 3 - One Lunar String
The String is found in Desolate Deep, specifically the Desolate Pocket area. It is low rarity and has no bait or weather preference, making it easy to catch on any rod. The catch needs the Lunar mutation, so the best dedicated option is the Moonlight Rod, which gives a 100% chance for the Lunar mutation. Alternatively, use Mutated Sharky or appraise a String using a Mutation Totem.
Return all items to Dr. Crookspine to receive the Scavenger Rod.

How Do You Get the Meteoric Rod in Fisch?
Travel to the Northern Expedition and find Astral Matthew in the frigid area. Jump up the elevated area to find him. His quest runs across two separate stages with multiple tasks each.
Astral Matthew's First Quest
Task 1 - One Cosmic Relic
Use a Starfall Totem to trigger a meteor shower. When a meteor lands, a pink beam of light shoots upward from the impact point and is visible from a distance. Walk to the beam and collect the Cosmic Relic on the ground.
Task 2 - One Moonstone
Get Moonstone from your aquarium, from a Meteor Totem drop, or from the Daily Shop when it appears in stock.
Task 3 - One Solar Blaze or Nova Frozen Walnut
Fish in the Overgrowth Canal with Cerulean Fang rod and Starlight Worm bait. For the Solar Blaze mutation, fish during an Eclipse event. Fan of the Eclipse rod gives the best odds, and Wicked Fang rod provides a 30% chance as an alternative. Return to Astral Matthew. A cutscene plays and meteors fall across the Northern Expedition.
TIP: For the Nova mutation, fish during a Starfall event with Cerulean Fang and Starlight Worm bait for the highest probability.
Astral Matthew's Second Quest
Task 1 - Break 10 Fallen Meteors
Equip the Pickaxe and interact with all 10 meteor crash sites around the Northern Expedition. Meteors are marked with a blue star glow and are visible from a distance. Work from the top of the island downward since descending is easier than climbing.
Task 2 - One Quartz Glass
Travel to the Cryogenic Canal area. Make your way onto the bridge and go all the way to the bottom underneath it. A dark portal entrance is at the base, walk through to enter the Cryogenic Canal Stone Cavern, a brand-new secret fishing area. The Quartz Glass is an Exotic rarity fish here. Use Magnet bait and fish during Foggy weather for the best catch rates.
Task 3 - Five Solar Blaze Stalactite
Fish with Wicked Fang Rod plus Garbage Bait while an Eclipse event is active. Most players fish in the Crimson Cave for this, though Tidefall also works. The Solar Blaze mutation is needed on these catch though.
Task 4 - One of Each Gemstone (Ruby, Amethyst, Opal, Lapis Lazuli, Moonstone)
All five gemstones drop from Meteor Totem events on Ancient Isle. Your aquarium also provides most of them passively. Farm with a Meteor Totem until all five are collected. Moonstone is the rarest of the five and can take the most Totem uses.
Return to Astral Matthew to receive the Meteoric Rod.
Meteoric Rod Stats & Showcase

| Lure Speed | 75% |
| Luck | 175% |
| Control | 0.05 (+5%) |
| Resilience | 25% |
| Max Kg | 550,000 kg |
Mutations: 20% chance for Cragged (7x multiplier)
Passive: Every 4 to 6.5 seconds, a Meteor falls onto the minigame. Up to 5 Meteors per catch. Dodge the Meteor for +10% Progress. If the Meteor hits your Control Bar, you lose -15% Progress instead.
How Do You Get the Rod of Singularity in Fisch?
This is the most complex rod to get in the update. The quest chain starts at Abyssal Zenith and ends with Merlin after catching five different secret fish from five hidden areas across the map. Here's everything you need to do:
Compete the Abyssal Zenith Quest
To reach the starting NPC, go to the Abyssal Zenith area in Sea 3, swim down to the black hole portal at the bottom, and swim through it to enter the Abyssal Zenith Astral Cavern. Talk to the NPC inside to begin the quest.
Task 1 - One Sparkling or Shiny Celestial Crowned Anglerfish
Fish in the Abyssal Zenith secret cavern itself. Use the Celestial Rod for its 15-fish buff activation, then swap to the Requiem Rod with both a Rainbow Totem and a Sparkling Totem active to maximize the Sparkling or Shiny mutation chance alongside the Celestial mutation.
Task 2 - One Nova Hardened Glass
Fish in the Abyssal Zenith secret room. Use Cerulean Fang rod and Starlight Worm bait with the Aurora weather active. The Nova Hardened Glass is an Exotic fish here.
Task 3 - 12 Nova Gold Pieces
Travel to the Mine Shaft zone. Use Crab Cages and Starlight Worm bait. Do not use Aurora or high-luck bait for this one, the fish has a naturally high spawn rate in Mine Shaft and extra luck is not needed.
Task 4 - 12 Celestial Scrap Metal
Fish in The Depths during daytime with the Celestial Rod and Garbage Bait. Activate the Celestial Rod buff (15 catches), then swap to a faster rod like Plague River to maximize catch speed while the Celestial buff is active.
Return to the NPC and receive a Dyson Sphere item. Take this item to Merlin.
Complete Merlin's Quest
Merlin sends you to catch five specific fish, each from a separate hidden area. Use a high-luck rod such as Requiem or Plague River with high-luck bait at each location.
| Fish | Location | How to Get There |
|---|---|---|
| Stabilizer Core | Abyssal Zenith secret cavern | Same black hole portal as before in Abyssal Zenith |
| Unstable Crystal | Boreal Pines ice lake | Find the ice lake in Boreal Pines. Swim to the very center of the lake to find a dark portal and enter it |
| Umbra Matrix | Everton Forest | Find the pond in the center of Everton Forest. There is a cave opening at the water's edge. Swim or walk in and it teleports you to the fishing area |
| Singularity Control Unit | Cryogenic Canal | Go to the Cryogenic Canal bridge, descend all the way to the bottom underneath, and enter the dark door at the base (same entrance used for the Quartz Glass earlier) |
| Stellar Wiring | Snow Cap | Pop a Blue Moon Totem on Snow Cap. Requires a clear night weather before the totem can be used. Once the Blue Moon is active, jump into the lit area at the base of the peak to enter the secret fishing room |
Once all five secret fish are caught and returned to Merlin, you receive the Rod of Singularity.
Rod of Singularity Stats & Showcase
| Stat | Value |
|---|---|
| Lure Speed | 618% |
| Luck | 287% |
| Control | 0.08 (+8%) |
| Resilience | 28% |
| Max Kg | Infinite |
Mutations: 25.92% chance for Nova (6x), 20% chance for Umbra (9x), 18.54% chance for Singularity (10.618x)
Passive:
- While the fish is inside the fishing bar: +1% Forced Progress per second, Control Bar moves -90% slower
- While the fish is outside the fishing bar: -Infinite% Resilience, Control Bar moves +50% faster
- 10% chance to duplicate a caught fish. If duplicated, a further 25% chance for a second duplication
Special Mechanic: When catching a Singularity or Umbra fish, multiply Final Fish Weight by 1.286x for bonus money and XP.
NOTE: The Rod of Singularity's unique mechanic inverts standard fishing behavior. The control bar slows dramatically when you are on the fish and speeds up when you are off it. This means the fishing minigame feels completely different from every other rod in the game
Frequently Asked Questions (FAQs)
Toxin Burst is recommended for both the Silver Rusty Bolt and Scrap Metal tasks since its extra catch mechanic generates more attempts per session. For the Lunar String, the Moonlight Rod is the ideal pick.
The Scavenger enchantment is available through Common Enchantment Relics and reduces the Battery Casting drop rate from 1 in 100 to roughly 1 in 34 in Mine Shaft. Using it alongside an Otter pet, which also passively boosts Scavenger drop rates, pushes the odds down further.
Yes, the Abyssal Zenith secret cavern is used for both the Stabilizer Core (Merlin's quest) and the Nova Hardened Glass and Sparkling Crowned Anglerfish tasks from the earlier NPC quest. It is worth doing all tasks that send you there in the same session.
