Astraeus Serenade Quest in Fisch – All Details
The Astraeus Serenade is a new fishing rod that was added in part two of Merlin’s Update. However, this has always been a secret, and nobody noticed it until a few days ago. This quest cannot be triggered manually and can be accessed only if you’ve the required items in your inventory.
Moreover, this quest has several different parts to it, and only after you’ve completed these parts, you’ll get the elusive Astraeus Serenade Rod. So, sit tight and let’s get into all the things that we know about the Astraeus Serenade in Fisch.
How to Complete Astraeus Serenade Quest 1 in Fisch

To activate the chain of quests, you need to interact with Merlin. However, the quest triggers only if you have the three items in your inventory. The quest cannot be triggered manually as it is a hand-in dialogue. Ironically, all the items are the same and can be found in the same place. Below, we’ve listed all the items you’ll need and the rods required to catch them.
| Radiant Crystal | Fishing Rod |
|---|---|
| Breezed Radiant Crystal | Wind Elemental Rod |
| Serene Radiant Crystal | Duskwire Rod or Polaris Serenade Rod |
| Celestial Radiant Crystal | Celestial Rod |
Radiant Crystals can only be obtained by fishing in the Mineshaft pond inside the Chasm. To enter the Chasm, you need to go to Sunstone Island. From there, you need to enter the Chasm and fish for the required mutations on the Radiant Crystal.
How to Get Radiant Crystal Mutations
You’ll need to gather three mutated variants of the Radiant Crystal, namely Breezed, Serene, and Celestial. These special mutations can’t be obtained by appraising. Instead, each one must be caught directly, and only with its corresponding fishing rod.
Breezed Radiant Crystal – How to Find
The Breezed Radiant Crystal is secured by using the Wind Elemental Rod, which becomes available after completing the questline in the Northern Expedition region. The rod gives a 25% chance to apply the Breezed mutation on any catch. However, you need to level 800 to activate this quest.
Serene Radiant Crystal – How to Find
The Serene Radiant Crystal is considered the most difficult to get due to restrictive rod options. Previously, the Polaris Serenade Rod offered a 20% mutation chance, but it is no longer obtainable. The Duskwire Rod is the only available option, with only a modest 2% to 4% chance, which makes the grind considerably longer for anyone without the legacy rod.
Celestial Radiant Crystal – How to Find
The Celestial Radiant Crystal is far more straightforward to acquire. Using the Celestial Rod guarantees a 100% mutation rate, making it the most reliable method by far. This rod can be crafted at the Ancient Archives, which unlocks after you’ve completed the Ancient Isle puzzle. It typically requires a small group of four people to solve it.
However, there is also an alternate option, which is during the rare Heavenly Sparkling Event (admin event). You can catch a Celestial Radiant Crystal with any rod, but only at a slim 5% chance.
How to Enter Mineshaft
To access the Chasm, you need to go to Sunstone Island first. However, you need to collect all the shards for Merlin from the different rifts first. Once you’ve completed that part, you’ll get another option while interacting with Merlin, saying, “I need to enter The Chasm.”
So, to enter the Chasm and reach Mineshaft, you need to get Merlin’s Veil now. It is crucial, as it grants you access to the Chasm. If you don’t get the Veil, you’ll not be able to enter the Chasm.
How to Craft Dusky Thread in Fisch

Once you’ve got all three mutation Radiant Crystals, head back to Merlin, and a new dialogue prompt will appear saying, “Psst, hey, I noticed you have the stuff to make something secret…”
Then, select the craft option, and it’ll give you the Dusky Thread item. The Dusky Thread is the first item that is required to unlock the powerful Astraeus Serenade rod in Fisch. We’ll update the article once we get more information related to Astraeus Serenade and its quests.
