Use Great Apiel lures to catch a lot of fish. Suspending bait helps increase the visibility and the fish appeal. A poorly set hook will slip from the fish's mouth.
Recommended season
Fall is the best time for fishing.
Secret fish
There are two legendary fish, a monster char and a giant king salmon.
Salmon River
After caching the monster char, Salmon River will always be open to fish at.
Largest fish
The biggest fish you can catch is the Chine Roach carp.
Mystical Carp
You can not change tackle in the Mystical Carp room. The bait in the Mystical Carp is a butterfly.
