I'm not really clear on the magic mechanics. Is the magic in the character or in the weapon, or is it some combination of the two?

Basically, is it:

- Character picks up a different weapon and the magic they can do changes.
- Character picks up a different weapon and the magic they can do is the same and behaves in the same way.
- Character picks up a different weapon and the magic stays the same but behaves in a different way?

Or

- Character picks up a different weapon and just flat out can't use magic with it?
