Deep One

“An ancient creature that dwells in the blackest depths. Its form suggests it existed long before normal fish, perhaps even before the oceans themselves.”— in-game Bestiary description

Deep One guide

Two zones list the Deep One, a Rare fish that the wiki places in Atlantis and Kraken Pool. It bites on Truffle Worm at night, with no weather or season restriction, and the entry describes an ancient creature from the blackest depths. Its average weight is 33 kg.

A price of C$20 per kg gives it an average of C$660, 368th of the 742 documented fish by value, which is solid for a Rare. It also pays 400 base XP. No maximum weight is recorded, so you cannot tell how big a lucky one gets.

Rare company documented in the same zone includes Eldritch Horror, Massive Marlin, Starlit Weaver and Titanic Sturgeon, so Atlantis offers plenty of Rare options. Abyssal Specter Rod, Champions Rod, Depthseeker Rod and Tempest Rod are the rods sold in those waters. If you already carry Truffle Worm, fish at night: with no weather or season gate to wait for, it is an easy target to plan around.
