I am at the Hot Springs part were I have to get the Ice Crystal and Big White Fat Fish. I got the Crystal but have no idea where to get the fish. Anybody know where I can get it?
From fishing. Or just check shops in Giran. Goes for about 1m on Sieg.
From Stratics guide for SWS 3rd class change but it's the same for any fat big white fishy thing:
Now comes a really horrible part - you need to fish. Train your Fishing, Pumping and Reeling skills to lvl 24. I purchased an A-grade pole and 100 Purple High-Quality lures. I fished for approximately 90 minutes before catching a Big White Fat Fish, you may have better luck (I didn't use any fishing shots either)
