I've been trying to find what Malatium does in Feruchemy, but I can't find it, in a thread here, in The Coppermind, in the Arcanum. It's as if it doesn't exist, there isn't even a question about it I can find. So have we just never thought to ask Brandon what it does? I would think he would tell us as it will(probably) never come up in the books. Or am I crazy and we already know?
