I was near zoneline to Twighlight Sea, working on my alcohol tolerance while foraging getting a bunch of rockweed bulbs and useless feathers, then moved a little to /loc -949.38, -1772.86, -98.14 and got 3 Red Sands Cactus in a row, then more rockweeds
Sometimes loc does seem to factor in on the chance of forage. When I've been to certain zones for different items, I have had better luck in certain spots than others. It is still pretty random. I took a ranger with 180 forage and druid with 200 forage. Took abot a half hour to get this item. I moved from the twilight zone in to the loc below, and then after no luck, moved again to the west side of the zone, just south of the deep zone in, loc was neg 255, pos 1545. After about the 3rd try, I got it.
You have GOT to be kidding me. It took nearly an hour before I could get ONE of these. After that I tried foraging for over THREE hours for a second one. In frustration I ended up buying one off another player.
