Lance naturally doesn't limit Sofia in concocting those potions; he even encourages her to dabble in them, otherwise how can he "steal" (crossed out) learn?
As much as he says so, Hamlet isn't like other loose feudal territories in the Empire; most resources are controlled, and various plant materials are in Grendel's hands.
Do you think Grendel would easily hand over materials to her?
Not to mention, Sofia basically has no money at hand. When Bastia ran away, it was already unexpected; those devoted fans couldn't offer a penny.
Now she relies on advanced wages to afford meals, and as for accommodation, she stays with Margaret and Laura.
One could say she's entirely benefiting from her two roommates; otherwise, how could she have such good living conditions?
A single room? It's Lance's mercy they're not shoving her into a large dorm.
When it comes to things involving supernatural power, money is necessary. But in Hamlet, there are no devoted fans to pay for her.
