Been farming for hours before i desided to try my bad luck on the Rolanberrie version. The Goblin Juice dropped on 3rd goblin. Then I noticed it wasnt an item but a key-item. Checking my Temporary key-items learned me i been waisting all those hours farming because I already had the Goblin Grub. Must have sneaked into my files some other day without realize it, you dont have to have anything flagged to receive these key-items... @.@
The NM's are very easy to kill with my PLD70/thf35
If you complete the quest "Sparkling Light" you wont have any problem getting to the ??? at the Beaucedine Glace exit in Batallia Downs using the Flower warp.
The other 2 points for Flower warp are getting behing Banishgate 2 in Garlaig Citadel and pass from North Gustaberg over the mountain wall to South Gustaberg
The best way to get to Sauromogue NM is passing through the past and use the MAW
