“

In the extreme upheaval caused by gravity spheres, it is almost certain that material culture created by the Voyagers will have been displaced─some, we presume, now plunged underwater. As the depths may hide rare relics, it falls to our talented fishers to recover them from the sediment─or from eager fish who may have mistaken them for food. This will be an extremely difficult task, demanding the utmost precision and delicacy, but we have the greatest faith in the skill of our contributors!

Strategy

Euhedroturtle is the target fish for this mission. It is a large-jawed fish and the only !!! at this location, and requires Fisher's Intuition from catching two Burrow Bolos. It bites around 23 seconds.

Brown Bolo is the intuition-granting fish. It is a large-jawed (!!) fish that bites between 16-18 seconds, but only if the player has the lure message "A pointed shadow shimmers in the water!"
Two Brown Bolos are needed to grant the Fisher's Intuition. (Brown Bolo cannot be Double Hooked or Identical Cast.)

Setting up Fisher's Intuition with Brown Bolo

Cast out and use Ambitious Lure until you get the "A pointed shadow shimmers in the water!" message.
- If you get the message, catch the !! bite between 16-18 seconds. (DO NOT use Double Hook or Triple Hook: You will only get one fish.)
- If you do not get the message or do not get a !! bite between 16-18 seconds, use Rest and try again.
Catching two Brown Bolos will trigger Fisher's Intuition for 6 minutes and 20 seconds.

Catching Euhedroturtle

After getting Fisher's Intuition, immediately use Chum, cast, and then use Ambitious Lure.
Catch the first !! bite you get, then use Surface Slap on it.
Keep repeating Chum and use Ambitious Lure until you get a !!! bite (and then catch it).
