Scientific Lure

Island 5's bait tier, for the endgame fish (values reported in the 1,360-1,700 range).

Catches: Anglerfish, Blobfish, Oarfish, Superdwarf Fish, Stonefish.

Only Destructoid confirms this tier by name; Game8 marks these fish's requirements as "TBD." Kept at community-reported for that reason, though the fish existing at all is corroborated.
