If she's skimming around in the beginnings, she'll very rapidly learn that all 'basic' crafting, like anywhere before the upper ranks of Tier 3, is all about...
...getting spellforms right enough that they snap into the ruts worn into reality! This explains the weirdness of the Earth-enchanted sharp knife! It wasn't really crafting that spellform for sharpness! It was getting it roughly recognizable enough that it'd snap into the same shape as a spellform cast a billion times before in this reality!
Or to put it another way, the fundamental basis of enchantment in Kekaro is a child scrawling a shape in the dirt sufficiently recognizable that their mother can pat them on the head and say, "Yes, dear, that's a very nice dragon" and correctly guess that it's meant to be a dragon rather than a roc.
