With the second draft of Calamity done and awaiting editor revisions, I thought I'd take this opportunity to re-approach a very common fan question. Do we learn Regalia's weakness in this novel, and if not, would you mind telling us what it is here?
Brandon Sanderson
Boy, I do get this one a lot. I'm wary of saying anything until Calamity is out, not because Regalia's weakness is specifically relevant, but because I've found that even the most innocent of things I say can sometimes lead to spoilers. The nature of the weaknesses is a big part of the three book arc of the Reckoners, so I don't want to hurt anything.
That said, as I mentioned, Regalia's weakness is not actually relevant. I've just been avoiding the question for reasons stated above.
Regalia's weakness was being proven wrong. If you could figure out something she'd done incorrectly, and prove it to her so she couldn't avoid the truth, she'd briefly lose local control of her powers. But I didn't want that book to be about figuring out/using her weakness, in order to distinguish it from books one and three, which use that as the major plot. So I avoided bringing up the idea, or really even using it in the story at all.

How hard would it be to trigger exactly? For example when David called Regalia to his location in the Reckoner hideout she figured out that she was searching for it in the wrong location. Is that why she took a while to appear or was there something specific about that situation that made it not count?
Brandon Sanderson
Yes. That is a time that would trigger her weakess.
