Hemalurgy and Kinetic Investiture Storage

[Trusk'our he/him]

I found this WoB and it got me thinking;

Questioner

With spikes, would you be able to actually transfer Breaths, when they get to the other planets?

Brandon Sanderson

So spikes rip off pieces of the soul and so Breaths are not going to be part of the soul. You could maybe get a divine Breath but I haven't really decided on regular Breaths, they're kind of stuck there in the Physical Realm which is not a thing that spikes are dealing with. Divine Breath, potentially, because that's something that's actually melding onto your soul. But, you know, when you're using the Breaths they reach through to the Spiritual Realm so, maybe if you got it while the Breaths were kinetic, right, while you're using them, then you might be able to rip them off. I'm not a hundred percent certain on that one.

Bystander

There's still things to decide upon.

Brandon Sanderson

Yeah there's still things, like I have to kind of see. My instinct says no right now. But, you know, how they interact is not something that I have-- Yeah.

This question was mostly meant to answer whether regular Bio-Chromatic Breaths were vulnerable to Hemalrugic transfer, but it also hints that Hemalurgy may be able to take Kinetic Investiture, such as that which is being used to fuel Allomancy or Surgebinding.

There's a good chance this isn't true (as the WoB is from 2015), but if it is true, I think it could lead to some interesting stuff.

I think that if you could take Kinetic Investiture via H-nicrosil you could potentially siphon off an Allomancer's Investiture as they burned a metal (embedding the spike in them and letting it continually strip them of the Investiture as it is drawn from the SR), similar to how Feruchemy can siphon off attributes for later use (could also be used instead of A-chromium to Leech someone).

You may be able to implant the spike into someone else (or spike your own Investiture for later use, simply keeping the spike imbedded in yourself and using the proper Intent or Command) to give them access to a ready to use reservoir of power that they could use in leu of metals to burn, kind of like how a Surgebinder has their Stormlight in their body ready to use in the amount they want or how Marasi was able to absorb and direct Unkeyed Dor in the amount that she wanted- no limitations of burn rate involved.

This could be another possible hack for augmenting Allomancy, allowing for great bursts of power that can be sustained longer and in a more stable fashion than with A-duralumin.

One thing to note is that Hemalurgic Decay may be the result of Innate Investiture within a Spike turning into a form of Kinetic Investiture, likely Ruin's version of Stormlight perhaps? The only reason it isn't visible is because not enough Investiture is leaking from the spike all at once, but perhaps if it were somehow collected then it would be.

So I think that if this was possible, the Kinetic Investiture would leak out of a Spike much faster due to it already being Kinetic rather than Innate.

Perhaps, though being implanted in a body should prevent accidental decay.
