Bones is an experimental potioneer. Potion making is an incredibly common practice, and many magic disciplines like Elementalism and Weaverism have their own traditions and recipes. Some even know how to mix a potion or two without knowing much about magic at all. But these potions tend to be weak or completely inert and limited in their range of effects.
People like Bones force potions to be more powerful and versatile by going much further then traditional potion recipes go in complexity, studying wide varieties of recipes, testing and of course experimentation. There aren’t a lot of individuals doing this, the normal image of potion making is one of old world nostalgia, the experimental potioneers are, to many, like if someone tried to summon demons with an easy bake oven. Except that experimental potioneers are successful if they don’t kill themselves with a bad potion or exploding equipment.
