Zone from Surefall into Quenos Hills...go stand in the grass..."Forage" ...foraged 10 times with max forage/AA's capped for forage and foraged 3 Saps out of 10 attempts. Hope this helps :-)
Unless you enjoy frustration(to those of you whom do, kudos) To those who truly need this item.. Zone into Quenos Hills from Surefall and stand on grass..forage get what you need and get out. Easy-peasy.
With a forage skill of 200 plus Machette, making skill of 220 plus AA Forage Mastery 1, I still only got one of these after an hour of foraging while sitting at SG zone in. If someone figures this out please post it!
After reading posts Many tks people i tryed foraging closer to zi from SurefaLL gLADE. GOT 1 BESIDE the tailor and his sister and one over at the ruined building east from zi. Never got any south of that though so stay North around zi.
I have made a fair amount of the juice, and the only place this item is found is in Qeynos Hills. I have never found it in the Glade itself.
I used to make special trips to QH to forage for this, but I found a better way. I changed my bind to SFG. Each death gives me a chance to get some more. Now, instead of hanging out in the Nexus while I wait for a rezz, I "load please wait" into SFG, zone into QH, and begin to forage. Now my rezz wait time is spent constructively, as I can get enough of this sap just foraging during what would otherwise be pure down time, to keep me fully supplied.
