Interview #977: Cosmere Q&A - 17th Shard, Entry #175

Douglas

And now some magic mechanics questions:

1) What benefit does compounding copper get? Exceptionally clear and detailed memories? Memories that can be split into a new coppermind while still remaining in the feruchemists mind? Something else?

2) How does Feruchemical luck work? If a chromium compounder tried his hand at day trading on the stock market, what would happen? Would it make him choose stocks that were coincidentally going to go up anyway? Would it change stock prices by altering the world around him? Would it fail because the required scale of action is too large? Something else?

3) This might have been specified in the books, I don’t remember, but does Duralumin expend itself as well as the metal it’s used with? If it does, I’ve got this theory that its effect is actually just to cause a regular flare, not a superflare, but it affects itself in a feedback loop that keeps forcing the flare higher until it runs out.

So, I’ve said before that I want to hold off on talking about different forms of compounding and types of twinborn until I can address them in the series. So I’ll have to RAFO the first two. However, in answer to the third one, yes you DO expend Duralumin in the process.
