Hi, I'm new to the boards. I've been playing a Dresden Files game for the past few weeks, and am still getting to grips with the ground-rules. Having had a wacky idea between sessions, I thought that, rather than spring it on the referee unexpectedly (hi, Dave), I'd try and get some feedback on it first.
In our current campaign we're dealing with a memory curse that causes other people to forget about the person who's been cursed. It manifests itself, to the Sight, as a malevolent presence in the victim's head, from which snake-like pseudopods lash out at those around him, biting out chunks of their memory.
My first thought was that a simple magic circle might be enough to contain that sort of spirit attack, but it's a bit of an extreme solution given that one of the PCs is currently affected, and I doubt he'd have much fun being alone in his room for a session.
There was an offhand remark at the end of last session, to the effect that he should try wearing a tinfoil hat, and that got me thinking along the lines of headgear, which gave me an idea.
What if the character were to wear a hat with a wide, circular brim (such as a traditional wizard's hat), and then empower the hat brim as a magic circle? Would that work as a portable magical barrier that would help rein in the curse?
On the general subject, I couldn't find any clear-cut rules in the RPG book on the creation and properties of a basic magic circle. I know from the novels that it's very basic magic, to the extent that even a Pure Mortal could create one, but I'm not sure what would be required to do it in-game, or how much protection it would offer.
