....what defines as a weapon for your magic to work? I dont want to start anything I am genuinely curious.

Weapon Magic is a form of Semantic-Type magic, so it can be flexible in that regard. It really does have to be a weapon though—I used this charm as an example in order to not freak out anyone in the shop. It transforms into a magic staff if you feed it some mana.
*The charm disappears*
If I have to define it, I'd say a tool used offensively in order to cause direct damage to a person or thing. But the easiest way to think about it is "If I have to ask 'is this a weapon,' it's not a weapon." Or at least, I won't be able to summon it.
