Full List of Luminescent Cavern Bestiary in Fisch
To complete the Luminescent Cavern bestiary in Fisch, you must catch 8 unique fish. But before you start fishing, you must unlock the Luminescent Cavern by finding Keystones in Fisch. Once done, you can cross the Mysterious River and start fishing in the cavern.
These fish range from common to exotic, and each requires specific weather, season, time, and bait conditions. The bestiary includes legendary, mythical, and secret fish, each with its own progress tracker.
Luckily, you won’t need the secret fishes to 100% this bestiary. However, there are two exotics, and one is rare to get, which makes the total number of fishes in this bestiary 10. That said, here’s the complete list for the Fisch Luminescent Cavern bestiary to guide you:

Best Tips and Tricks to Complete Luminescent Cavern Bestiary in Fisch
Completing Fisch’s Luminescent Cavern bestiary is easy, as it is in a small fishing area. Optimizing your fishing gear and techniques significantly accelerates this process. This guide will help you select the most effective tools and methods for rapid Fisch Luminescent Cavern bestiary completion.
1. Best Rods for Luminescent Cavern Bestiary
One of the best rods for this bestiary will be the Challenger’s Rod and Tempest Rods due to their faster progress speed. Although the pool does not give you crates, you will end up getting a lot of Stalactic. That is why rods with good luck, like the No-Life Rod and Heaven’s Rod, can be perfect for this bestiary since any bait works fine with them.
However, the rare fishes in the pool come with high-resilience debuffs. To tackle that, I suggest you go with the Poseidon Rod. If you want to make a lot more money from these limited-time fish, you can also use the Ethereal Prism Rod in the Luminescent Cavern Bestiary.
2. Best Baits for Luminescent Cavern Bestiary
Luck matters the most when you are fishing in the cavern. That is why we highly suggest following the table above for the best baits for each fish in Luminescent Cavern. In case you are running out of preferred baits, for a beginner, Seaweed is a good option. It increases your lure speed and resilience by a decent amount, enough for the lower-tier catches.
However, to maximize high-tier fish catching, Night Shrimp and Weird Algae are a must. These will increase your luck and improve the chance of finding Mythical or Exotic fish. If you are using a rod with 200+ luck, go with the Coral bait instead for resilience.
3. Use the Best Enchants for Luminescent Cavern Bestiary
Fishing in the Luminescent Cavern Bestiary is only tricky if you don’t have a good rod. In such a case, you can optimize your rod by using a good enchantment. Given that the fish come with higher resilience, Resilient and Quality are my preferred picks for new players. If you have Exalted Relics, you can try for the Mystical enchant, which also improves progress and luck.
As more than half of the fishes here come with a negative progress speed, you can get the Steady or Flashline enchant too. I suggest you go through our best Fisch enchants list and pick your favorite one for the Luminescent Cavern bestiary.
4. Best Rod, Bait, and Enchant Combo for Luminescent Cavern Bestiary
The best all-around setup for the Luminescent Cavern bestiary in Fisch is the No-Life Rod with Night Shrimp or Weird Algae as bait. Pair this with Mystical and Steady enchants to deal with the high-resilience debuffs that most cavern fish carry.
These choices make Mythical and Exotic catches far more consistent while keeping progress speed steady. If you’re aiming to farm profit alongside completing the bestiary, swap to the Ethereal Prism Rod with Night Shrimp bait once you have 200+ luck for stronger returns.
Most of the cavern’s rarest fish spawn during foggy nights in spring and autumn, which makes these the best conditions to focus on. To catch the Exotic Colossal Blue Dragon specifically, you must keep using the Sundial Totem in Fisch until a thunder effect arrives in the cavern. During that time, look for the dragon swimming in the corners near the waterfall. You can only catch one of them during every spawn.
Sticking to this loadout during those windows will let you clear the majority of the bestiary without needing constant gear swaps. This combination of rod, bait, enchant, and timing gives you the most efficient path to finishing the Luminescent Cavern log while also setting you up for good rewards.
So that’s how you can complete the Luminescent Cavern bestiary in Fisch. Have you started catching them to unlock the Luminescent Oath rod? Let us know in the comments below.
