If an Allomancer found themselves on Nalthis or Roshar, would they be able to use chromium on someone using Stormlight or Breath?
I am staying away from answering too many questions like that until I start having it happen. But do know that the magics interact... some ways they interact very naturally, some ways, they don’t. One way I’ve released is, you could use bronze on most forms of Investiture to find it. So you can extrapolate that some of these things would work. But not necessarily all. All of them could be made to work.
