So, my friend and I were wondering about savanthood.
Say I'm a zinc twinborn compounder, and I constantly flare my metalminds, would I become a normal zinc savant or can you become a new Ferring savant?
Actually, at the book signing I recently went to
, someone asked about this exact thing. Brandon indicated that compounding is a separate, unrelated thing to savanthood. He may have misunderstood the question, but I don't think so.
Q: Can you compound metalminds to the point you beome like a savant?
A: A savant happens because persistent use of the power has an affect on your soul, warping it. Compounding is a very different thing. So while you could draw some very powerful effects, I would not call them the same thing even if they are imitating each other at certain points.
There was some more discussion about this in the same thread I linked above. Here is what I said, and what I still believe Brandon intended by his answer:
Although its possible he meant just what he said. If you think about it, when you're doing allomancy you are temporarily adding an effect or ability to your spirit that it isn't normally capable of doing. When performing Feruchemy (and by extension, Compounding), you are tapping into your own stored up attributes. You're not doing anything new, you're just affecting when you use your innate abilities and the extent to which you use them.
So I could see how performing a lot of allomancy- something that you're not normally capable of doing- would warp your spirit, while feruchemy and compounding- which allow you to tap into abilities that you ARE already capable of doing, just to varying extents- wouldn't warp your spirit.
One last point, somewhere (I wish I could find the quote) Brandon talked about snapping, and how basically, the soul cracks, and then investiture rushes in to fill in the gaps (He also implied that we see this same process in magic systems other than Allomancy- The Shaod in Elantris seems like a likely candidate). So by using that new Investiture/Allomantic power a lot, and frequently, it makes sense (to me) that that process could widen the cracks in the soul, allowing more investiture to seep in, and also causing the warping that Brandon talks about.
Feruchemy, on the other hand, as far as we know, doesn't work like that. One doesn't need to "snap" in order to become a Feruchemist, one is apparently born with the ability. Thus, no crack-widening soul-warping effects. In theory.
