wanna enchant my 2h weapons, but where do I get the ingredients besides picking them up in the wilds? Aren't there any good sellers for ingredients? I found 1 decent seller in Dyrford village but any advices would be welcome!

There's a Stronghold upgrade that will make crafting ingredients available for purchase.  I think that the merchant doesn't have some of the ingredients for the highest-level enchantments, but the selection is larger than I remember seeing on any other vendor.

 

Aside from that, I think there's a vendor in Defiance Bay that sells some crafting ingredients.

Ok thanks, didn't think about that stronghold upgrade. The Defiance Bay vendor is in Copperlane I assume?

There is a secret vendor in Defiance Bay who sells the rare gems if you do a little task before you talk to him.
