I would like for vendors that either as an individual or in partnership with two or more individuals, could reasonably be thought to supply the physical craftsmanship and the enchanting skill needed to upgrade weapons to certain thresholds... but I think also that Damon, in particular, makes a point of noting that he really does not have a good set up here, and barely even has metal that he feels comfortable calling steel to work with. He may have the skill needed too create or improve base level enchantments, but he absolutely cannot do it here, I feel. We shouldn't be seeing +1 gear as generic merchant fare in Act 1 at all, only finding and earning/winning/finding them as loot.
