Fisch's The Depths expansion update added a variety of new things to the game. However, the Isonade remains one of the mysteries since it can be quite challenging to track down. Not only does it spawn in specific locations, but it is also not always available to reel in. Its rarity further adds to the difficulty of the task.

As such, this brief guide will highlight all the details about this mysterious fish and help you catch it.

The Isonade is a Mythical rarity fish that only spawns in "strange whirlpools". You cannot find it in other locations or the regular whirlpools, so the real difficulty is in waiting for the phenomenon to trigger. Fortunately, it happens every 15-20 minutes in the game.

Now, once you get the “A strange whirlpool has opened in your server” notification, hop into your boat and sail toward its direction. Now, all you have to do is get as near the whirlpool as you can, cast your line, and wait for the Isonade to bite. However, given the fish's rarity, this can take some time and several tries.

Below, we have all the other information about the Isonade that you should be aware of before you begin your hunt for this elusive creature.

Rarity - Mythical
Preferred bait - Truffle Worms
Preferred time - N/A
Preferred weather - N/A
Preferred season - N/A

For the Isonade, all you need to worry about is getting the Truffle Worms bait. These can be obtained by opening Coral or Volcanic Geodes.

The best fishing rods to catch the Isonade

The other important thing to worry about is choosing the best fishing rod when you're out there hunting the Isonade. You need something with good Luck and Resilience stats. We highly recommend the Heaven's Rod, as it boasts an impressive Luck stat. You can also go for the Rod of the Forgotten Fang if you don't have the Heaven's Rod.

New or mid-level players can also opt for the Arctic Rod, which has balanced stats. This is important because the Isonade puts a -50% progress speed debuff when you reel it in. Below is more information about the aforementioned fishing rods.
