Over the last few days, the Fisch community has been buzzing again about a secret that many players thought was buggy or unfinished. Surprisingly, this hidden content has been in the game since the release of Merlin Part 2. Also check out our Fisch Codes for more rewards!
And now, we finally know what it leads to: a special item required to obtain a brand-new rod called Astraeus Serenade. If you want to be one of the first players to unlock it, here’s everything we currently know from the community and confirmed developer hints.
What Is the Secret Astraeus Serenade Quest?
This secret quest is tied to Merlin and requires three specific fish, but for weeks nobody could figure out how to hand them to him. There was no option in his normal dialogue, so most players assumed the secret was broken or unfinished.
It turns out the quest was working the entire time. The catch is simple: You must have the three required fish in your inventory at the same time.
Only then will Merlin show a new dialogue and allow you to craft a secret item. Because players didn’t know how the hand-in worked, everyone eventually gave up searching, and the secret was forgotten until now.
Official Hint From the Developer
Recently, developer Nick confirmed a major clue. His message clarified that: The reward for this secret is an item for the Astraeus Serenade, and fish mutations are important. This reveals two critical facts:
- The required fish are not normal versions.
- You must have mutated variants of the three fish.
- The specific fish involved remain completely unknown.
There are no public hints about which fish they are, their rarity, or where they’re located. That means only community teamwork can solve it.
Why Did the Quest Suddenly Resurface?
Images started circulating online showing Merlin with a special prompt saying the player had the “stuff” needed to craft something secret, followed by a Craft button.
These screenshots came from the wiki team’s development mode. Once they spread through the community, players realized the secret was actually active, not broken. From there, speculation exploded again.
What Is the Reward?
Completing the Merlin secret will not give the Astraeus Serenade rod directly. Instead, you’ll receive a required item that unlocks the path toward obtaining the rod.
This also debunks the old rumor about an “Evil Serenade,” which is now confirmed to have been just a joke. The real upcoming rod is Astraeus Serenade, and this secret quest is the first step toward it.
How You Can Help Solve the Quest
Since there are no exact hints beyond “three mutated fish,” the community needs as many players as possible experimenting. You can contribute by:
- Collecting rare and mutated fish.
- Keeping mutated fish instead of selling them.
- Checking Merlin’s dialogue whenever you add new mutated fish.
- Sharing results, even if they fail, to help narrow down the options.
With enough players testing combinations, the secret will eventually be solved.
The Secret Astraeus Serenade Quest is currently the biggest mystery in Fisch. Although information is scarce, we now know exactly what to chase: three mutated fish that trigger Merlin’s hidden crafting dialogue. The item he gives you will be the key to earning the Astraeus Serenade rod in a future update.
If you discover anything—whether a theory or a failed combination—share it with the community. You might be the one who finally cracks the code and kicks off the next big discovery in Fisch. Until then, keep fishing, keep experimenting, and let’s solve this mystery together.
