I'm looking for some suggestions on how to implement a Magic System similar to the Arcanum CRPG or the one used in the "Harry Dresden - Wizard" series by Jim Butcher. Basically, technology and magic don't mix very well - if you're a strong magic user, technology tends to fizzle when you try to use it (computers fry, car engines conk out, automatic guns jam, etc.)
I suppose Unluck fits the bill, but if anyone has other suggestions or suggestions on better quantifying it, I'd appreciate the feedback.
