Beginning the quest at Sweetheart Shores
Your journey begins at Sweetheart Shores, a limited-time event hub island decorated for the Valentine update. Here you will find Nurse May, the NPC responsible for the Cerebra Rod questline. After speaking to her, she assigns you a two-part mission.
The first part focuses entirely on exploration. You must travel across multiple islands in the Fisch world and retrieve ten hidden vials. These are static collectibles placed in hard-to-reach or visually concealed spots. While no combat is involved, traversal can be time-consuming if you do not know the exact locations.
All vial locations across the map
Each vial is placed in a specific landmark area on a different island. Knowing the exact spot will save you significant travel time.
| Island | Exact Location Description |
|---|---|
| Terrapin Island | Inside the “M” Cave |
| Grand Reefs | On the deck of the pirate ship |
| Mushrove Island | Tucked at the back area |
| Snow Cap Island | Inside the Lost Rod Cave |
| Forsaken Shores | At the top near a wooden bridge |
| Castaway Cliffs | Left side of the docks |
| Lost Jungle | Near the Verdant Rod location |
| Rosit Bay | Opposite the laboratory |
| Ancient Isles | On top of a crane at the peak |
| Skoria Reach | At the top of the volcano |
Most of these spots are elevated or hidden inside caves, so you should bring a fast boat or movement-enhancing gear to reduce travel time. Once all ten vials are collected, you return to Nurse May to trigger the second half of the quest.
Catching the Valentine event fish
After turning in the vials, Nurse May shifts the objective toward event-exclusive fishing. You must catch three special Valentine-themed fish at Sweetheart Shores.
| Required Catch | Location |
|---|---|
| Kissing Garamis | Sweetheart Shores waters |
| Heart Cookies | Sweetheart Shores waters |
| Heart Sand Dollars | Sweetheart Shores waters |
These fish spawn only during the Valentine event period and are tied to the event pool at Sweetheart Shores. If spawn rates feel low, increasing your luck or using rods with faster progress speed helps significantly.
Once all required fish are caught and turned in, Nurse May rewards you with the Cerebra Rod.
Cerebra rod stats and passive abilities explained
The Cerebra Rod stands out because of its layered passive bonuses that affect both progress speed and profit potential.
| Passive Effect | Value |
|---|---|
| Instant Progress Fill | 30% on every catch |
| Stab Chance | 30% chance for +6% extra progress |
| Heartburst Proc | 10% chance for 8x catch multiplier |
| Fish Weight Bonus | +22% |
| Progress Speed Bonus | +22% |
The 30% instant progress fill activates automatically on every catch attempt, meaning your progress bar immediately jumps nearly one-third forward. This dramatically reduces struggle time on high-resistance fish.
The 30% stab mechanic provides an additional burst of progress, stacking effectively with the instant fill. Combined with the +22% progress speed, you will notice significantly shorter catch durations compared to standard rods.
The most powerful trait, however, is the 10% Heartburst effect, which multiplies your catch value by eight times. While it does not trigger every time, over extended farming sessions it leads to massive profit spikes.
The +22% fish weight bonus further increases selling value, making this rod particularly effective for money farming.
Why the Cerebra rod is worth the effort
If you are aiming to maximize leveling efficiency or build currency quickly in Fisch, the Cerebra Rod offers a rare combination of speed and multiplier potential. Unlike rods that focus purely on luck or strength, this rod improves both catch consistency and profit variance.
It performs especially well in mid-to-late progression zones where fish resistance normally slows down farming. Because it boosts progress speed and provides instant bar fills, it reduces downtime and increases hourly catch output.
The rod also pairs well with bait that increases luck or weight bonuses, compounding its already strong multipliers.
Location flow strategy to complete the quest faster
A practical approach is to plan your vial collection route in a circular path across the map rather than jumping randomly between islands. Starting from Terrapin Island and sweeping outward toward Skoria Reach minimizes backtracking. After collecting all ten, return directly to Sweetheart Shores to avoid unnecessary detours.
Once you begin the fishing portion, remain at Sweetheart Shores until all required event fish are secured. Switching locations will not help, since the required species are tied to that specific event zone.
The Cerebra Rod is one of the strongest event-based rods in Fisch, combining speed, consistency, and explosive profit potential. While the vial hunt requires full-map exploration, the payoff is substantial. If the Valentine event is active, you should prioritize completing Nurse May’s quest before it ends, as event-exclusive rods often become unobtainable afterward.
With the Cerebra Rod equipped, you will notice faster catches, heavier fish, and occasional massive payout spikes that make long grinding sessions far more rewarding.
