Everyone is making good points.
The Entity interlude showed us that Tinkers are merely building things and tapping into branches of physics our fleshy three dimensional minds haven't reached yet. They might be 'cheating,' but they are definitely following rules and limits, just they have an extra processing unit on their brain that is keeping track of the math of the bullshit they are pulling if that math cannot be expressed in human terms.
Artifacts (and magitech) require the Magical Materials, which are simply Not Available at the moment. It is POSSIBLE to make Orichalcum or Moonsilver in Creation from their mundane sources; this becomes infinitely less likely on Earth Bet for Moonsilver because there is no Wyld Zone (or if there was no one would understand it as such). For Orichalcum, technically one could make the occult mirrors needed, maybe? But that would require amounts of raw knowledge and ambient essence around to make work, let alone the precise conditions (sun hitting lava) and time/focus (keep said mirrors aimed at the gold melted on the lava for dozens of hours per ounce, or whatever).
Yeah, not likely.
Artifacts can be made via ANY craft discipline; they simply require exotic components of symbolic value and a sliver of legitimate magical material. Some lesser artifacts can get away without legitimate MMs in them, but they are lesser for a reason.
Magitech is a craft discipline all its own, as in, you have to buy the skill Craft(Magitech) up from zero.
The five Big Craft Disciplines are Craft(Fire, Water, Wood, Air, and Earth) - which between the five of them, ostensibly cover every mundane non-engined, non-electrical thing you could possibly make- and their shiny magical equivalents. As soon as you start burning fuel or including circuits, you have technically bypassed the Creation-style limits of the five Crafts.
Note that on Earth Bet, the case could be made that Craft(Fire) could reliably be used to machine all the key parts of an automobile. The internal combustion engine is merely a bunch of very exactly shaped and oiled bits of metal, in the end. In Creation such ideas break down because advanced matter phase-change reactions that are repeated incessantly (the cycling of said engine) will offend gods somehow unless they are appropriately bribed to turn fuel into fire at a particular rate consistently. In other words, the more advanced you try to take mundane physics on a small scale, the more you have to waste energy and time appeasing all of the gods of all of the parts involved such that they keep following the same rules. This is accounted for by Magitech, where the fiat-indestructibility of magical materials means little wear and tear (usually) and the direct feed of energy from Hearthstones means no negotiating for consistent current or voltage.
This line of crazy logic is why building an Atelier-Manse (a factory that rapidly produced copies of a mundane object) in Creation required a four dot manse and ungodly amounts of spiritual infrastructure. Lord help you if you want a Factory-Cathedral that actually rapidly assembles artifacts.
So, yeah. Craft(Magitech) is (thankfully) out of reach. Gods are bastards.
Craft(Genesis), on the other hand, is still on the table. Maybe.
Also, on a more frightening note . . . what about Craft(Armsmaster) or Craft(Kid Win)? Note that Tinkers seem to have their own specialties (Armsmaster's is taking tech and minimizing it, which is how he has such a fancy halberd- it's not that there is anything particularly unique about any aspect of its tech, but it has LOTS of tech all in one blade).
No, I am not currently planning on making Taylor into a godlike uber-supertinker. Note that tinkers in-universe have both the ability to *manipulate* things on a level mundanes can't, and the mental boost to understand it. Craftsman Needs No Tools would only grant Taylor the ability to replicate most mundane tools and techniques; she'd have to progress to the next tier up, "I can craft a blade from the smell of freshly blossomed roses" level of magical tools bullshit to even have a chance of beginning to actually copy or create Tinker tech. Like, the dimension-cutting blade needs a screwdriver slipped between realities to tweak that 4th-dimensional screw. Kid Win can just do that with a screwdriver, but Taylor can't.
Comprehending tinker tech, however, is another story. Fewer things are more helpful that a Solar Crafter peering over your shoulder and giving advice.
As for the applicable power levels . . . well, highest end magitech in Wonders of the First Age gives us crazy powered armor suits with zillions of gadgets. I wonder where we see that kind of thing in Worm? Heh.
Warstriders are another thing altogether, although I wouldn't put it beyond Dragon if there was actually a tactical need for a Really Big Robot.
As I try to brainstorm what the first few waves of her fighting style's evolution will be, I keep mentally drifting back to FFVII: Advent Children. Heh. Only one specific part, though.
