I'm farming Pretty Sandstone and Beautiful Sandstone for the Scorpion ensemble. I just got enough BS for the helmet a few minutes ago, but I've been going for at least an hour and I haven't gotten a single additional PS (I have 3 already).
I've been using Vanir's Treasure (purposefully dying to mini Skoll to save myself the effort) to farm, but does anyone have any missions that seem to be more effective? And would the drop rate of Pretty Sandstone increase if I farmed in the single-player tavern? --- "[Gravity Rush] is like losing your virginity; sometimes you won't know what you're doing, it's over way too quick and it's totally amazing!" -CBrate
