Blizzard has updated some info and new screens of the three Artisans on their official site. The screens show four levels for each of the Artisan wagons, with the wagons in what appears to be a basement of Bastion’s Keep; it’s certainly not their Tristram location, and it doesn’t look anything like the desert Act Two setting we’ve seen the Mystic’s wagon in previously.
There are 10 (at last check) upgrade levels for the Artisans, so it seems like these 4 shots are samples; maybe level 1, 3, 7, and 9, or thereabouts. Click them for much larger views, with all four steps for each Artisan in the same shot, to save you on needless clicking.
The crafting recipes are updated as well, even compared to what we’ve had in the Diablo Nut since the last patch, but they’re clearly nowhere near finished. If you look at the updated Blacksmith’s plans, for instance, are mostly still placeholders, with every entry above the “Master” level just listing the item type, and +2-6 random modifiers. (Sets and Legendaries from the Blacksmith plans still have no stats listed at all. )
Note that Master is a fairly low level competency; so basically just the first 100 out of 302 listed Blacksmith recipes are not placeholders. (Naysayers may cite this fact in their *D3 will never make an early 2012 release* rants in comments.)
Incidentally, as much dialogue and story as they’ve worked him into, I guess this is out of the question, but why is the Jeweler still in the game? His initial design had him crafting rings and amulets, along with upgrading and unsocketing gems. Now that crafted jewelry seems to be out of the game (they’re saving it for the expansions, most likely), the Jeweler does nothing but socketing (which could easily be transferred back the Blacksmith) and upgrading gems.
Remember in D2, when we had a handy cube that could upgrade gems (and runes) for free, anywhere, at any time? Like all D2 systems, the D3 devs have greatly upgraded that old thing, and now we have to go back to town, run to an NPC, and spend gold to upgrade gems. In other words, gem upgrades in D3 are both expensive and inconvenient. But hey, that’s a small price to pay for witty, Chinese-accented conversation with the subtly-named Covetous Shen.
