I don't think we have to terribly worry about empowerment abuse with the Ringwraith multiheros though, so #magicboost should be fine.

If you wanted to give Angmar a fairly 'unique' buff based on their magic sites, you might just give Mt Gundabad #incscale 1(Increases Productivity).

In a slightly related note, I had a beautiful vision for something like a Minas Morgul nation whose home province increased Death and Misfortune, and you basically had to do everything in your power to keep the scales down(or just abandon your capital, I suppose)
