Took me just over 4 weeks to get the full set for my Artemis Bow. Started casually and managed to get 4, then slowed down and grinded maybe a hour a night for a week. Then went back to it, bringing out my Chocobo, and managed to get a few more. Then hit a brick wall where I got nothing for over 25 hours. That was disheartening, but I was determined to finish. Left it for a day to have a little break, came back and got 3 in 5 FATEs. Thought I'd finished but I got my places mixed up and ended up with 2 of the same >.< Grinded for another hour and finally managed to get the full set! Was glad it was finally over, but I still intend to get a second set for my Stardust Rod soon.

It's annoying, boring and tiresome but you have to stick at it and hope for the best. Use your Chocobo, use PF to grind in groups, grind different places... If you're getting burnt out, take a break to relax.

Good luck to everyone still grinding, hope you get yours soon too.
