How to Get Cerebra Rod
To unlock the Cerebra rod, travel to Sweetheart Shores (Valentine Island) and enter the house where Nurse May is located. Talk to her and she’ll give you a quest to find 10 vials scattered across different islands. You have 7 days to complete this quest before the Valentine’s event ends and the rod becomes unavailable.
After collecting all 10 vials, return to Nurse May, and she’ll give you a second task. You need to catch and bring her 2 Kissing Gourami, 2 Heart Cookies, and 1 Heart Sand Dollar. These are Valentine’s event fish that you can catch during the event period. Once you deliver all the fish to Nurse May, she’ll reward you with the Cerebra rod.
The quest isn’t particularly difficult, but finding all 10 vials requires visiting many different islands. Make sure you have a fast boat to travel between locations quickly. The vials glow, making them easier to spot, but some are hidden in caves or on top of mountains that require climbing.


All 10 Vial Locations in Fisch
Here are all 10 vial locations you need to visit:
- Scoria Reach – Climb to the very top of the volcano.
- Mushgrove – Go to the back of the island in the lower area away from main paths. The vial is on the ground.
- Terrapin – Head to the cave entrance on the opposite side from the cultist cave. The vial is near that entrance.
- Ancient Isle – Climb to the highest point of the island and look near the crane structure. The vial is right next to it.
- Snowcap – Move toward the back of the island and find a small cave. Inside the cave near the lost rod area, the vial glows at the back.
- Roslit Bay
- Grand Reef
- Forsaken Shores – Climb to the very top of the mountain. Once at the peak, you’ll spot the glowing vial.
- Lost Jungle – Head to the back of the island. If you can’t pick it up immediately, move your character around slightly until the prompt appears.
- Castaway Cliffs – Climb to the top of the hill and the final vial will be waiting there.

Is Cerebra Rod Worth Getting?
Yes, the Cerebra rod is absolutely worth getting, especially since it’s limited-time and will never be available again after the Valentine’s event ends. The rod has excellent lure speed at 200%, good resilience at 50%, and a solid progress speed bonus of +22%.
The main weaknesses are the 95% luck (not quite 100%) and the 50,000 kg weight limit, but both problems are fixable with enchants. If you’re a collector, you definitely want this rod since it’s limited-time. Even if you don’t use it as your main rod, having it in your collection is valuable because it will become rare once the event ends.
