Sometimes, Vin and Kelsier seem to notice people burning metal when there was a coppercloud around. So I was wondering if copperclouds can change depending on how much the Smoker or Mistborn wants it?

It’s gonna depend on a lot of factors. How strong is the coppercloud? How strong is the person piercing it? How Invested is the individual? And these sorts of things. There are deliberate points where Vin pierces a coppercloud that I intend to be moments that you’re supposed to pay attention to in the story. And this is done intentionally; this is not, like, a binary on/off.
