i made these to bridge the gap on bonecraft from horn arrowheads >> scorp arrowheads.
on asura:
Wind - 5k
B.Jaw -40k
R.Horn-48k (4k x 12horns)
imo.. its one of the better paths. materials are easy to farm and skill ups arent too bad. also not too expensive to just buy everything. Sell these back to the npc for ~ 900g or savem for GP.
Hope this helps ~
