Craft is an XP black hole. As I started earlier, magical materials are nigh impossible to make. Orichalcum is the only one she'd have ANY chance of getting all the necessary conditions for, and even then, she'd need to arrange the conditions to craft the magic mirrors she'd need to smelt orichalcum.
No, she's not pulling magical materials out of her butt just yet.
Now, she always wanted to be a tinker. She'll give it the college try, but believe me you, the same total time-effort spent in Craft without access to MM, in a world with modern industrial capacity? Is absolutely not an obvious positive return on investment.
Even CNNT at first isn't really vital, because a factory can be used to rapidly make stuff while she goes and does something only she can do, etc. Efficient distribution of resources.
If we really want to be particular about her power scaling, her dots of Essence going up only grow her raw output. Her perspective, her true potential, her out-of-context nature? That manifests as she gets dots of Occult. She needs the knowledge, base framework, AND the infrastructure to even begin abusing Solar Craft on Earth Bet, and she's currently 0 for 3. As she is now she can't really match the output of a robot or a tinker of a given specialty.
