The paths section has, for example, an entire Class pathway that leads up to crafting extremely-high-powered enchanted-alchemical consumable magical arrows for use by mithrilplate adventurers to one-shot younger dragons. In the numbered section there are courses that teach tier-2 crafting spells that can help raise fortress walls in days if not quite overnight, providing you have Earth Magic and Fire Magic and Water Magic as prerequisites, and MP of at least 200. Checking the earliest prerequisites of long pathways will reveal that a lot of things start with Runic reading and inscription; but it's not clear if Bella can just read Runes and write them down again. She has a feeling she might be able to do that, based on how writing Lictic worked out for her. If she wants to create powerful items, she should also probably take at least the basic smithing classes; lots of things rely on being able to put metal into the shape you want it to be.
Bella will probably still have to overcome some degree of culture shock about how long it supposed to take her to learn basic smithery... namely, on the order of a month, assuming she doesn't pay for Upgraded versions of anything. There are Teachers here and students get Skills, and the entire economy is based on the equivalent of how far that lets people get along the pathway of personally building an entire television set from scratch in a world that has not started making standardized screws.
