After banging my head against the keyboard from wasting my time in Qvic killing ghosts, I found a much easier way to get the taelosian mountain wheat, of which you'll need 4 in making Bristlebane's challenge meats, among other tradeskill recipes. It seems to be somewhat more "common" killing mobs in Kod'taz, by the Yxtta zone line. To give you an idea, in a couple hours I got 3 taelosian mountain wheat and 6 meldstones.
#2 it does not drop in Riwwi or it is extremely rare there. I was helping 2 different pally farm for their 1.5 and probably spent close to 20 hours total. Saw lots of taelosian wheat but not mountain version.
