Giant Seadevil guide
Giant Seadevil is a Mythical fish from Abyssal Zenith. You can catch it with Fish Head bait in Clear weather during Autumn, and no time of day is listed. The wiki describes a massive, terrifying fish with a glowing lure and teeth as sharp as the finest blades.
Its weight is the headline: 4,000 kg on average, between 2,000 kg and 12,756.5 kg, with a maximum weight that ranks 84 of 663 fish with a documented heaviest catch. At C$1.8 per kg the rate is low, yet the average sale reaches C$7,200, which ranks 144 of the 742 documented fish. A catch grants 3,800 base XP.
That puts it in the top fifth of fish by value and well inside the top fifteen percent by size, which is strong for a Mythical. The listed conditions are not strict, just Clear weather in Autumn, so it is realistic to plan sessions around it. For players looking for a reliable big sale, it is a good target: bring Fish Head, wait for clear autumn skies, and expect a payout in the thousands.
