The best gear is crafted, doesnt quite answer your question other than there is nothing to spend money on in the game really. --- Opinions are like testicles. Kick them hard enough, it doesnt matter how many you got.... -Varric
There are vendors at Rathir and at Mel Senshir that sell top level gear you can break down for parts. I saw a vendor with greater and master crafting pieces, but I forgot where. I know there is one though. Maybe someone else can shed light on that. That would be the ideal way to get good gear --- Sent from my iPhone via PowerFAQs 1.9
I think right now, from what I can see through my gameplay, is that the top tier items are for sale over at Mel Shenshir, at least the most expensive gear. Most other places are pretty crap and then the rest of the gear is either found or crafted.
I would recommend just buying the gear from Mel Shenshir and break them down for parts to craft your own equipment.
