How to Fish
In order to fish, you must obtain bait from the Fishing Shop in Malangdo (198, 118). You must also be equipped with a Fishing hat (sold in the Fishing Shop or use the one provided by the Fishing Guru). Once you're near a fishing spot, use the Fishing Rod like you would an item to start. You will see two options: Automatic and Manual fishing.
With Automatic, you will continue to fish until you have less bait than what you wanted to fish. It will also continue to do so until you move your character. In Automatic, you're at the mercy of chance.
With Manual, you control your character. To reel in a fish, sit your character. To give it some line, stand. If you let the fish get too close or too far, you fail. There will be a progress bar on your head. Each time it ends, you get a fishing point. Once the bar disappears, you'll catch your fish.
Your success at fishing is determined by your STR, DEX and LUK. Fishing level and fishing gear, as well as bait, also affect your success. There are a total of 50 fishing levels.
