Oh. My apologies. But then, what's so different from a beheading to a bullet in the eye? Trying to find the power's limitations, anyways. All I can think of is that the metals are in the stomach, and that a beheading would separate the brain from it's power source... *shrug*
Another thing, at some point it is mentioned that if you don't "burn" away the metals in your stomach through allomancy, they can make you sick. Does this mean they waste away over time if not used quickly? (Stomach acid, I guess, not to mention the metals going through your system) And, if that is the case, what does this mean for compounders, as they have to at the very least touch a metal to store a feruchemical charge, then ingest it to burn it away. They must use multiple pieces of metal, studs I would assume, to store the excess of what they burn from compounding, which they then eat and possibly compound again.
Which makes me ask, is there a limit to the feruchemical charge that can be stored in a metal? Based on size or anything like that? Also, if I use a goldmind to store health, say, as a bracer in my arm, and I then ingest shavings of it, is part of the charge stored in the goldmind in the shavings? Which would imply an equal distribution of the charge across the mass of the metal...
Sorry, rambling. Any thoughts?
