Huh, nice find! This h2g2 or whatever looks like a pre-wikipedia kind of thing. The post has a key at the bottom that shows it is a reply to a parent post that no longer exists, but I'll bet it was along the same lines as this post http://h2g2.com/dna/h2g2/A683688

Dave's comment (assuming it was Dave) that he only "used CHAINMAIL for the early magic section in the first month we played BLACKMOOR" is interesting since he usually only mention using CM for combat and there doesn't seem to be any hint he ever used the spell complexity thing - at least no hint of it in later writings.

When I google for specific sentences in the quoted sections above, google suggests links to the BBC, but when I click on those, they lead me right back to h2g2.

The style of writing looks very much like Dave's style when posting on Finarvyn's forum to the point that I almost thought I had read this before...

I can say with high confidence that this post is from Dave.
