Why can't you sense Feruchemy with Bronze?

[+Invocation]

I wonder if it's different for Compounded Feruchemy due to the influx of extra power?

Despite being classified as an end-neutral system, there actually is some loss associated with Feruchemy when you tap at higher rates.  

But that's only when you tap at higher rates. And even then, it wouldn't be nearly as much as Hemalurgy, would it? Power isn't being created or destroyed. There isn't really a loss, it's just being used at a later point.

The "end-(whatever)" classification is only really useful relatively anyway. 

Feruchemy is not truly "end-neutral"

So for the Old Magic, in this classification system of end-positive, end-neutral, and end-negative, where would that fall under?

So, almost every magic in the cosmere is end-positive, almost every magic is relying upon an external source of Investiture to power it. So that phrasing is mostly more relevant to Scadrial than anywhere else, because that concept is how I'm dealing with things like the laws of thermodynamics, and even what they call end-neutral is relying a little bit on the power of Investiture to facilitate. So even an end-neutral magic system as they define it on Scadrial is actually not end-neutral. What you get put in you get out, but the power is facilitating that transfer… So that phrasing is kind of a... Take that as a science on.. Scadrial that does not extrapolate well, and may not even be 100% accurate.

That would have been a great thing to know before we did the cosmere magic panel. *laughter*

I look at it as, is an Investiture externally powering the magic, and if you look at Allomancy, yes it is. You are drawing that power out. Feruchemy, you are putting Investiture in from your own body, it's your energy transferring to Investiture, which is being stored, which you are then drawing out, and things like that. But that changing forms is facilitated by the magic. Whereas you're stealing stuff with-- So you could look, for instance at the magic on Nalthis, you could look at that one as being-- as kind of working as end-negative, meaning "I am taking it away from someone else", or end-positive depending on if you're the one receiving it or not. So again, it's a phrasing that can be useful as a tool but doesn't scale well to the other magics.

I think bronze can't sense Feruchemy because it's "quieter" like how lightweaving is "quieter"  then windrunning
