In this video, I go over farming white and purple gathering scrips with your fisher in Final Fantasy 14. I wanted to make an updated guide that focused just on fishing and highlight one of the best ways to farm white gathering scrips by fishing for the fleeting brand. I hope you find the video helpful.
