Sonar & catch hunters.

Sonar rank 0 shows silhouettes only, even beside the hook. Rank 1 adds size and depth bands; rank 2 recognizes species you have caught; rank 3 adds strength and behavior; rank 4 gives a full scan with exact measurements. A lantern accessory does not replace sonar ranks. Some predators only attack a hooked fish. Defeat an invader to unlock its wild species, then visit its native region. Keep smaller prey hooked for at least eight seconds: a suitable larger hunter may approach and take over the fight. Watch the warning, or Give line to release the prey safely. The Codex’s Catch Hunters guide shows requirements without falsely marking a discovery.

Step 1

Step 2
