4/5 pieces from bluefrog leves chests in about 2 hours a week ago. I forget the exact quest, but its one of the ones poppable closest to Bluefrog. Just stood on the highest rock in the middle of area, checked for chest (usually onely 1 I think...hope?) w/o having to move and dropped quest if none there. Lose a bit of gil that way but really helped to speed up the process. Thx for the abobve post lol..was hpoing there weren't any accessories to get too from chests.
