I'm thinking once I hit 25 and get raise... I sit out in Valkurm fishing and raising people. though... I don't think I've seen anyone catch anything but a monster off of the beach, so that may be a bad idea...
Yea but im doin it for the skill gain and tricoloured carp need shrimp lures to just attract them and theyre 4k each and your line can break (happened 5 times goin from 11 -> 20 fishing on Copper Frogs + Cheval Salmon) and I can't afford 20k in lost lures so I'm trying for Pipiras which use minnows which are 300 gil each at the guild and as I'm fishing at windhurst I don't have to run there when I get to 28 to do the next guild test as I don't plan to leave till I get that done (also need to build fame anyway so I can get Aspir)
Fishing 13 here. As far as I can tell watersday and lightningsday are the best fishing days. Firesday is the best day to break your line and or rod. Lightningday + full or new moon means lots of fish fast.
You can see when the moon phases will be at http://www.manakun.com/hari/
One last thing. Crayfish + wind Crystal = easy skill up to cooking level 3. They don't sell at all though.
