Island LabReport
English：Island Lab · Locations
An Ancient Lab on the south-western tip of Fishman Island, and the home of the Fishmen faction. The King Gurgler sits inside holding a Meitou Combat Cleaver, and his head is worth 60,000 Cats — the most concentrated bounty-plus-blade payout in the game.
The Island Lab is a minor location on the south-western tip of Fishman Island — the ruin of an Ancient Lab. It doubles as the headquarters of the Fishmen, and the King Gurgler sits inside it.
An island with no guards
Fishman Island is a green island at the southern end of the map — fertile, rainy. Everything the builders left is still in place; only the builders are gone. Fish Isle, the ruined city at its centre, is entirely infested now.
One thing is commonly misread: you do not need the Swimming stat to get here. The lightened strip on the map north of the island is a bridge, the same kind as the one connecting Black Desert City to the Scraphouse, and the one crossing the Wend river north of Blister Hill.
To mark the Island Lab on your map, use a Tech Hunters Map — it reveals one location at random from a list, and the Island Lab comes up 7.14% of the time.
Who is here
The Fishmen, also called Gurglers, are fishlike abominations. Individually weak, in numbers they are another matter entirely — like the Fogmen, they carry injured organic characters back to their nests, tie them to a pole and eat them alive.
Presiding over the lab is the King Gurgler, an Alpha Fishman. His wanted poster is worth reading:
WANTED: Giant King Gurgler WANTED for crimes of kidnapping and cannibalism of Catun residents. Neither man nor animal, the Giant King Gurgler is an enormous beast with more similarity to a hiveman-crossed-crab, ten-fold in size. Wanted dead. Thought to be dwelling south of Catun's shore. Head required as proof. UPDATE: The King Gurgler has been reported to be in possession of an ancient weapon of the fallen empire. Assassinate him and the weapon is yours to keep. REWARD: 60,000 Cats
That "ancient weapon" is the Meitou Combat Cleaver in his hands — one of very few in the game.
What is here
- AI Cores — occasionally found inside. That is the direct proof of what this place used to be. It was an Ancient Lab.
- Meitou Combat Cleaver — in the King Gurgler's hands.
- Gurgler Head — proof for the 60,000-Cat bounty, redeemable at any vendor.
Tactics
The lab has no traps; the difficulty is entirely numbers. The wiki's answer is the assassination route:
- Bring a character with high Assassination.
- Stealth KO a Fishman, then take its Foul Raw Meat — their death item, which kills them outright.
- If spotted, run, break line of sight, come back and repeat.
That turns one mass battle into many solo jobs, at the cost of time. Fighting straight is possible with an established squad — individual Fishmen are weak, but there are enough of them to drag someone down, and being dragged down here means the pole.
What it means for the player
The Island Lab is a mid-game target with unusually concentrated rewards: 60,000 Cats in cash, a Meitou weapon, and possibly an AI Core, in one trip.
The gate is not gear — it is whether you are willing to process an entire island of enemies. For assassination builds it is almost purpose-built; for straight fighters it is a good test of whether the squad can survive a swarm.
