<Snipped quote by KoL>

You'll want to be an Eastern magus for that, since Metal is an Eastern alignment. If you go Eastern, you can make a magus with a dual Elemental Affinity to Metal and Soil. That's for the base, at least, I don't really know what theme you want to go for past that.

I thought something on those lines as well. But weren't the Einzbern (not saying I wanna be one yet, just for comparison's sake) supposed to be masters of metal manipulation? I was thinking that maybe there could be a way as a Western magus to do that as well.

But the Eastern (more likely Chinese) approach might be easier to work out.
