I know, I know. I don't have a copy, though, and I'm waiting for the Inter-library loan to come in. For some reason, my local library has the third book, and a couple post-trilogy, but not the first or second.
Yeah, I kinda knew about Allomancy, though this is definitely more illuminating than the vague idea I had earlier.
Meanwhile, from that info, burning Plate? Good question. I'm obviously no expert, so I won't reply to this.
On the other hand, I will try to come up with another interesting thing: What would happen, theoretically, if you burned Nightblood? I mean, it is most likely impossible, considering that Nightblood basically devours Investiture, but what if it was possible?
