Dark Cloud 2

To catch a Baron Garayan, you must have the Lure Rod with a Fork Lure. The Fork Lure can only be bought from Olivie once she has been recruited as an ally. You can also buy the Lure Rod from her if you haven't made it or won it in the Fishing Contest already.

The Baron Garayan is only found in the Hot Springs of Heim Rada between the hours of 4 pm and 9 pm in-game time. To check the time, press . There is a bar on the bottom left corner of the screen telling you the adventure day and the time. Keep in mind that time will continue to advance while fishing.

Once you have the Fork Lure attached to the Lure Rod and the Lure Rod equipped, cast your line into the Hot Springs. The Fork Lure works similarly to the Frog Lure, except a slightly longer cycle. Tilt the Left, Right, Left, Right, Left, Right, Left, Right, tap , wait, repeat. Continue this pattern until an exclamation point appears over Max's head. Pull back on the once this happens, and you will begin to reel in the fish, just like any other fish. Keep in mind that a Baron Garayan is heavier than most other fish, meaning it's harder to reel in. You can increase the stats of your Lure Rod before attempting to catch the Baron Garayan, but it is not necessary.

PlaystationTrophies user Zertonium has made an excellent video on how to catch the Baron Garayan.
