What Changed: Key of Whispers Nerf

The recent Fisch update massively reduced the profitability of the Key of Whispers farm in the Cultist Lair, which used to be the core late‑game money method. Previously, most exotic keys here had an average sell value around 9 000 C$ each, and with size and mutation multipliers they regularly sold for well over 200 000 C$ per big mastered catch, especially during rainbow events.​​

After the nerf, those same keys now average roughly 600 C$ base value, which is a more than ten‑fold drop and completely kills the old “spam rainbow + Key of Whispers” strategy as a reliable path to billions. Because of how easy it was to force near‑guaranteed catches during daytime rainbow events with luminescent larvae and strong rods, this method was deemed too powerful and targeted directly.​​

Core Money‑Making Concepts You Must Use

Even after the nerf, the logic of making money in Fisch is the same: stack as many multipliers as possible on already high‑value exotics. Rods like Sea Overlord, Nate’s Blade, Fabulous Rod, and similar high‑tier options are strong because they naturally boost fish size, which then scales your sell value when combined with mutations like big, giant, or mastered.​

Weather and world events matter a lot; aurora events greatly increase luck and mutation outcomes, and rainbow events combine global luck boosts with time‑of‑day synergies for specific targets, making them central to any serious farming loop. Bait choice is just as critical: luminescent larva is a go‑to for many high‑value exotics, while some specific targets (like Cthulid) strongly prefer squid bait, so matching bait to the fish’s table is non‑negotiable.​​

Glitch potions and nukes push this even further; glitch potions duplicate every fish you catch for a period, while atomic nukes effectively simulate high‑tier mutations like mastered for every catch during the nuke window. Voided Gloves and similar late‑game gear then multiply your effective throughput by speeding up or enhancing your catches, making them essential to true “billions”‑per‑session runs.​​

Method 1: Sunstone Island Speed Core Farm

Sunstone Island is the first pillar of the new money strategy because it contains multiple good exotics in one compact, easily farmable zone. The standout is Speed Core, an exotic “fish” native to Sunstone with a strong base value per kilogram; according to community data, its base C$/kg is around 615.4, giving an average base sell around 769.5 C$ before size and mutation multipliers.​​

In practice, the guide shows normal Speed Cores selling near 100 000 C$ with just basic multipliers, and giant or mastered variants shooting up to around 130 000–200 000 C$ depending on size and mutation rolls. Another exotic in this area (the difficult‑to‑pronounce one mentioned in the guide) can reach around 175 000 C$ in value on a strong big mastered roll, so the combination of two high‑value exotics in one spot makes Sunstone extremely efficient.​​

Optimal Setup at Sunstone

For rods, the recommendation is to use Sea Overlord, Nate’s Blade, Fabulous Rod, or similar rods that naturally increase fish size and grant strong luck bonuses. Pair these with mutations and event boosts: aim for aurora events, and layer additional luck from things like Merlin’s Luck and any global server buffs.​

For bait, luminescent larvae is the main choice here, obtainable cheaply in bulk from tropical bait crates at Sunstone, which makes it both cost‑efficient and effective for the target exotics. The video emphasizes that even without perfect catching every time, the combination of Speed Core and the other Sunstone exotic will consistently yield six‑figure individual fish values under a good mutation and size roll.​​

Method 2: Treasure Island High‑Value Exotic

Treasure Island offers another strong exotic option, though it is slightly more specialized and partially gated behind older gear. To reach this spot efficiently, you should use the Traveler’s Whistle, which provides quick access to the island and minimizes downtime between rotations.​​

The big appeal here is an exotic with a higher average base sell value than most other options in the early methods list—roughly 10 000 C$ average, making it very competitive even before stacking multipliers. When you add aurora, Merlin’s Luck, good rods, and strong mutations, this fish becomes a very respectable moneymaker, particularly in extended farming sessions.​

Gold Shrimp Bait and Merchant’s Rod

This method is maximized by using Gold Shrimp bait, which gives an almost 20% catch chance for the target exotic when combined with Ruinous Oath and aurora, far higher than alternatives. The catch is that Gold Shrimp bait is only obtainable via the Merchant’s Rod, an old second‑sea item that is no longer directly available to new players, which restricts how many people can fully exploit this setup.​​

Even without Gold Shrimp, you can still catch the fish at around 10% chance with more common baits, and its per‑fish value remains strong enough to justify including Treasure Island in your rotation. While you are here, you can also appraise and sell other exotics and legendaries you pick up, adding passive income on top of the main target.​​

Method 3: Cultist Lair Cthulid and Cthulith Farm

With Key of Whispers nerfed, the Cultist Lair meta pivots from keys to two Cthulhu‑themed exotics: Cthulid and Cthulith. These fish sit on very favorable drop tables during specific events and zones inside the lair, giving you extremely high catch rates for consistently good‑value exotics.​

The key difference between the two is location: Cthulid spawns in the Hall of Whispers, while Cthulith spawns in the Passage Boats section once that event zone is active. Using the fish radar makes it easy to verify which is currently active and where you need to stand to maximize your time in the correct sub‑zone.​

Cthulid in Hall of Whispers

Cthulid is valued because it is extremely easy to obtain under the right setup; with Nate’s Blade and squid bait during an aurora event, the guide shows about a 47% catch chance, which is absurdly high for a good exotic. Unlike older methods that required stacking many rare conditions, this setup is comparatively straightforward: join when the server event announces a Cthulid spawn, equip Nate’s Blade, swap to squid bait, and fish continuously.​

Although its individual sell value is somewhat lower than the best Sunstone exotics, the sheer volume you can pull in at nearly half the casts being Cthulids makes this method incredibly efficient, especially with glitch potions doubling every catch. Because auroras are cheaper and more common after recent updates, keeping them active in public or coordinated servers is easier than before, further amplifying this farm.​

Cthulith in Passage Boats

Cthulith spawns during the Passage Boats event sub‑zone in Cultist Lair, and is described as one of the highest value targets among the featured methods. With squid bait during an aurora in this zone, catch chances climb again to very favorable levels, turning Cthulith into a premier “burst farm” option whenever the event is live.​

Because the Passage Boats zone only exists while its event is active, the recommended play is to immediately switch over to this area when the Cthulith abundance message appears, then swap back to Sunstone or other zones once it ends. The guide suggests rotating between Cultist Lair and Sunstone as events cycle, always anchoring yourself in whatever zone currently has the best combination of spawn tables and global luck.​

Understanding the Old Rainbow Key of Whispers Method (Now Nerfed)

Before the nerf, the Key of Whispers farm worked by abusing the interaction between rainbow events, daytime spawn preferences, and luminescent larva inside Cultist Lair. During a rainbow event, the entire server gained a huge luck boost (10×10× or similar), and because Key of Whispers is a daytime‑preferred catch, the combo effectively turned it into “press button → print money.”​

Players would use super‑easy rods like Analix or Fabulous Rod plus atomic nukes to guarantee top‑tier mutations on every key, capturing big mastered keys almost on every cast during the rainbow window. With keys selling for over 200 000 C$ each before the patch and being almost guaranteed during rainbows, players could generate absurd amounts of money in a very short time, which is why the developers slashed the value to around 600 C$.​​

Rod, Bait, and Mutation Optimization

Across all these methods, certain equipment and consumable choices show up repeatedly because they scale every target. Rods like Sea Overlord, Nate’s Blade, Fabulous Rod, and similar high‑tier rods buff fish size, which is critical because value scales with kilograms and multipliers like big, giant, and mastered are essentially size multipliers.​

Using nuclear items (nukes or atomic nukes) during peak sessions effectively simulates having high‑tier mutations constantly, letting you treat “normal” catches as though they rolled top‑end multipliers. On top of that, rods like Ruinous Oath or Luminescent Oath provide additional mastery or mutation effects, making them ideal for focused farming on specific exotics.​

For bait, the main recommendations are: luminescent larva for Sunstone exotics and many general high‑value targets, squid bait for Cthulid and Cthulith in Cultist Lair, and Gold Shrimp bait (where available) for the Treasure Island exotic. Matching bait to the correct fish table often doubles or triples your effective catch rate versus just using “whatever is cheap,” which is critical for pushing into billions efficiently.​​

Glitch Potions, Voided Gloves, and Reward Loops

Glitch potions are one of the strongest late‑game tools for money because they simply duplicate every fish you catch during their duration, effectively turning all your farm numbers into 2×2× without needing more RNG. When used alongside high‑value exotics like Speed Core, Cthulid, and Cthulith, this duplication can easily turn six‑figure catches into multi‑million sessions.​

The guide explains that glitch potions are common rewards from daily rewards, the black market, and repeatable “challenge” NPCs that can be run roughly every 15 minutes, making them surprisingly accessible for how strong they are. Voided Gloves, unlocked around level 1 900, further enhance your efficiency and should be considered mandatory for serious endgame farming once you reach that level threshold.​​

Putting It All Together: Rotation to Billions

To actually reach “billions after the nerf,” the idea is to rotate between these hotspots instead of tunnel‑visioning on the old Key of Whispers room. A typical high‑efficiency loop looks like this: idle or farm legendaries and exotics at Sunstone Island during downtime, swapping to Treasure Island when you have the right bait and rod, and immediately jumping to Cultist Lair (Hall of Whispers or Passage Boats) whenever Cthulid or Cthulith events spawn.​

Stack auroras, nukes, glitch potions, and top rods during these peak windows so every cast is as valuable as possible, then cool down by grinding other zones while your big consumables are on cooldown or events are inactive. As developers continue to balance extreme outliers like the old Key of Whispers method, the safest long‑term strategy is to focus on diversified high‑value exotics, multiplier stacking, and event awareness rather than any one “too good to be true” exploit.​​
