Overview[1][2]
Isonade is a known catch in Fisch, found around Strange Whirlpool — sells for about 6 C$ per kg. In-game bestiary: “The Isonade is a sinister creature that is assumed extinct. They are seeming to be a dream that is possible to be caught and captured. They only circle near Strange Whirlpools, they can even be the cause for one.”
The Isonade is a fish obtainable in Strange Whirlpools. Due to its high rarity, it makes for a challenging catch, moving erratically across the fishing bar. When reeling it in, -50% Progress Speed is inflicted. When hooked, an exclamation icon will pop above the player's head, and a bell sound is played - as with all fish. The Isonade is required for the Vertigo bestiary, and can be caught in Strange Whirlpools, but can't be caught in Vertigo.
