@fzer0 Actually there's a lot of that in Discworld, where a lot of the magic ritual is just for show.
@fzer0 Oh, and at least one of the spells has a back door - someone tries a spell, it doesn't work, the target says "I wrote that spell, you didn't think I'd invent a spell that worked against me, did you?"
@TimWardCam @fzer0 Pratchett was a tech nerd, he knew how these things worked.
