Marsh cocked his head slightly. “Oh? And what would be the greater advantage? Being immune to—but ignorant of—some Soother’s attentions? Or instead knowing—from your bronze—exactly which emotions he is trying to suppress?”

Vin paused. “You can see something that specific?”

Marsh nodded. “With care and practice, you can recognize very minute changes in your opponents’ Allomantic burnings. You can identify precisely which parts of a person’s emotions a Soother or Rioter intends to influence. You’ll also be able to tell when someone is flaring their metal. If you grow very skilled, you might even be able to tell when they’re running low on metals.”
