What is Isonade in Fisch?
Isonade is a high-value, Mythical-rarity fish in Fisch, known for its rarity and unique location requirements. It cannot be caught in open water or traditional fishing zones. Instead, it’s only available when fishing inside a Strange Whirlpool, making it a highly sought-after target for advanced players.
What bait does Isonade like in Fisch?
Isonade exclusively responds to Truffle Worm bait. Players should ensure they’ve stocked up before entering a Strange Whirlpool, as switching bait mid-session can waste time or reduce their catch chance.
What is the best rod to catch Isonade?
The Ethereal Prism Rod is currently considered the best rod for catching Isonade. It offers high luck, good lure speed, and strong synergy with Truffle Worm bait. Some players also report decent success with the Wicked Fang Rod, but the Ethereal Prism has more consistent performance when hunting Mythical fish.
Where do you find Isonade in Fisch?
Isonade is caught inside Strange Whirlpools, which appear randomly throughout the First Sea. These whirlpools are rotating bodies of water with glowing vertical light beams. You’ll commonly find them near Moosewood, Earmark Island, Roslit Bay, and the Statue of Sovereignty. Less frequently, they appear near Terrapin Island, The Arch, and Forsaken Shores. Entering one will teleport you to Vertigo, but the fish itself is caught inside the whirlpool — not Vertigo.
What does Isonade mean?
The name ‘Isonade’ is based on a sea creature from Japanese mythology. Described as a shark-like being with barbed tails, it is said to appear near violent storms and drag fishermen to their doom. Fisch leans into this mythology by linking Isonade to the unpredictable and violent Strange Whirlpools.
