The Lullaby Rod Mastery in Fisch is locked behind four riddle-style quests rather than the plain task lists used by most other rods. Each one upgrades the Lullaby with a permanent buff or hands you an exclusive cosmetic, and the final quest unlocks the rod’s Serene Hymn mode. The wording is deliberately cryptic, so what follows is the plain meaning of every riddle and the precise action that ticks each counter forward.
Quick answer: Finish all four mastery quests in order — Forever in Harmony, The Climb, The Collection, and True Ascension. Together they grant a Supporter Halo, the “Moon” bobber, doubled buff durations, faster metronome progress, and the Serene Hymn mode.
Mastery quests, riddles, and rewards
Here is the full set of mastery quests with the riddle text the game shows you and the reward each one pays out. The detailed solutions follow below.
| Quest | Riddle | Reward |
|---|---|---|
| Forever in Harmony | All for Nothing At All (0/180) | Simon’s Gift Supporter Halo and “Moon” bobber |
| The Climb | Thinking of the Way I used to Spend the time (0/20) | Doubled buff durations for the Lullaby |
| The Collection | Past is passed, and rather than regret the old, I can live it back the other way (0/6) | Increased progress speed on metronome hits |
| True Ascension | Use all that you’ve gained to rise Above The Clouds (0/1) | Serene Hymn mode for the Lullaby |
Forever in Harmony: All for Nothing At All
The counter reads 0/180, and those 180 are seconds. To complete it, you need every Lullaby status buff active at the same moment for more than three minutes straight. That means stacking Resistant, Quickening, Strengthening, Fortuitous, Prismatic, and Serenity together and keeping them all alive.
The practical way to do this is to land metronome hits across modes so each status refreshes before it expires, since perfect catches add duration and misses subtract it. Because the Serenity status comes from the Serene Hymn mode, you will be juggling all six effects at once while watching their timers.
Finishing it pays out Simon’s Gift Supporter Halo and the “Moon” bobber.
The Climb: Thinking of the Way I used to Spend the time
This quest asks for 20 catches, and there are two ways to fill the bar. Pick whichever one actually moves your progress, since one route may register more reliably than the other for you.
Method 1: Travel to the Abyssal Zenith using your Traveler’s Whistle and activate a starfall totem. Then perfect catch 20 Prismatic fish from the pool, using both your control block and the metronome mechanic to land clean catches.
Method 2: If Prismatic catches at the Abyssal Zenith are not registering, head to the Above the Clouds point of interest instead. Catch 20 Rainbow fish there while a starfall totem is active.
The reward is the doubled buff durations enhancement, which keeps every Lullaby status effect alive twice as long.
The Collection: catch six specific mutated fish
The 0/6 counter calls for six exact fish, each with the listed mutation and caught under the listed conditions. Match the location, bait, weather, time of day, and season where they are specified, and pay attention to which ones demand a perfect catch.
| Fish | Location | Perfect catch | Bait | Conditions |
|---|---|---|---|---|
| Rainbow Ancient Kraken | Atlantis | No | Shark Head | Night |
| Prismatic Mythic Fish | Ocean | Yes | Flakes / Super Flakes | Day |
| Rainbow Anglerfish | Ocean | Yes | Squid | Foggy, Night, Winter/Autumn |
| Prismatic Harmonic Dove | Above the Clouds | Yes | Worm | Clear, Summer |
| Prismatic Ancient Depth Serpent | The Depths | Yes | Truffle Worm | Night |
| Rainbow Voidglow Ghostfish | Abyssal Zenith | Yes | Squid | Foggy, Spring |
Completing the set grants increased progress speed on metronome hits, which speeds up reeling every time you nail the pendulum.
Tip: Keep all six of these fish in your inventory after catching them. You need them again for the final quest.
True Ascension: rise Above The Clouds
The last quest has a single objective, but it depends entirely on finishing The Collection first. You use the six fish you gathered there to open the path to the final area.
The reward is the Serene Hymn mode, which adds a +10% chance for the Serene mutation and +45% Resilience while active, and provides the Serenity status used in Forever in Harmony.
How to confirm each upgrade applied
Each quest closes out with a visible payout, so you can verify success without guessing. Forever in Harmony delivers the Supporter Halo and “Moon” bobber to your inventory. The Climb and The Collection apply their enhancements directly to the Lullaby’s passive, lengthening buff durations and speeding up metronome progress. True Ascension ends with a cutscene and adds Serene Hymn to the modes you can cycle through with the mode key. If a counter stops advancing, recheck that you are matching every condition exactly, especially the mutation, the perfect-catch requirement, and the weather, time, and season listed for The Collection fish.
