Can a person with free will cross a magic circle without breaking it?
Can a person with free will throw objects into a magic circle without breaking it?
Breaking it by moving an object into an circle seems to be very easy.
If so, where in the books does it say so? Obviously I can design a circle in a way that makes it "survive" throwing stuff in:(click to show/hide)
Good questions, but also:Yes. Sure, why not?
Can a mundane put a magic circle around their techie toys to protect them from visiting wizards?
