I ran across a moblin merchant in bastok a few days ago. All he said to me though was Bastok is too weak to trade with moblins. He is located in port acrros from the gusgen map wuest giver hiding in a corner
Well for threads there are way too many at the AH to be ALL dropped IMO. Now following the basic clothcraft guide:
2x base ingrediants=1 Thread 3xThread=Cloth
So I would guess this can be synthed... although I haven't seen anyone do it yet.
Judging from the item descreption for the thread I would guess Artificial lenses
So maybe 2x Artifical Lens with lighting crystal?
I can't try to tonight (I'd either get the cannot be combined message and know it's wrong or i'd get the craft skill too low and know I was right) but if I can find some cheap single lenses (... >.<) i can try...
