How to get the Astraeus Serenade Mastery in Fisch

To get the Astraeus Serenade Mastery in Fisch, players must complete the following set of quests.

Perfection of the Stars - Astraeus Bobber

For this one, you must catch an x2 Spectral Serpent with the Serene mutation. Equip the Astraeus Serenade Rod and go straight to the Brine Pool inside the Desolate Deep to start fishing for this mythic fish under the following conditions.

  • Weather: Clear
  • Time: Night
  • Season: None
  • Bait: Truffle Worm

Remember, there is only a 10% chance of getting the Serene mutation with the Astraeus Serenade Rod. So, be patient and keep fishing until you get two fish with the same mutation.

Winds of the Gods - Astraeus Title

The next one requires you to catch the x1 Profane Leviathan with the Breeze mutation. Like the previous one, equip the Astraeus Serenade Rod and go to the Cultist Liar through the Terrapin Hideway on the Terrapin Island. Once you reach there, you can catch the fish in the final Sanctum area. I have mentioned the Ideal conditions for the Profane Leviathan below.

  • Weather: Foggy
  • Time: Night
  • Season: Winter
  • Bait: Luminous Larva

Since this is a secret fish and you also need the Breeze mutation (10% with the Astraeus rod), it will take quite some time to finish this quest as well.

Astra Divinity - Firefly Entity Passive

For this final quest, you must catch x25 Secret fish with the Astraeus mutation. This is quite a grindy task, as you must catch a Secret fish, and it should also have an Astraeus mutation(15% chance with the Astraeus rod), which is quite a tough combo to get in the first place, and you must reel in 25 of them. Still, it is achievable if you target the right secret fishes. Below, I have mentioned some secret fish species that are slightly easier to catch than others.

Once you get 25 such fish, you will unlock the Firefly Passive, which provides the following perks to your rod.

  • 100% chance for Quiet mutation
  • +3% chance for Shiny 
  • +3% chance for Sparkling 
  • Every perfect catch reduces the time by 30 seconds

Astraeus Serenade Mastery FAQs

How long does it take to get the Astraeus Serenade Mastery?

It will take anywhere from 1 to 3 days to finish the Astraeus Serenade Mastery. This timeline is based on 3 to 4 hours of gameplay each day, with breaks in between.

What is the best reward for finishing the Astraeus Serenade Mastery?

The best reward from the Astrateus Mastery is the Firefly passive stat that gets permanently attached to your rod. Additionally, I like the Astraeus Bobber, which looks cool and mysterious.

Do you need to use the Astraeus Serenade Rod to complete the Mastery?

Yes, you must equip and catch all the fish parts of the Mastery quest using the Astraeus Serenade rod.
