As a Hemalurgic conasuir, I can say that it probably won't be too bad. Probably. Hemalurgy is dangerous, but with mag-tech evolving as it is currently in the Cosmere, I see it becoming less of a threat than just another (albeit very fascinating and unique) manifestation of Investiture. Its biggest thing is that you can steal people's powers and make a single really Invested being (or many Invested beings), but with Southern Scadrien medallion tech, advancements in Awakening, and Roshar's Fabrials, it isn't going to be the only thing capable of such feats forever; power is becoming more accessible to the masses, not the individual few. My assumption is that aluminum, when used in Hemalurgy, steals all Invested powers, but because aluminum itself cannot conduct Investiture, the Hemalurgic charge isn't kept to be stappled onto someone else. This would explain why aluminum "removes all powers". As Hemalurgy actually removes a piece of the Spiritweb, yes, powers removed via aluminum Hemalurgy would be permanently lost if not regenerated via some other form of Investiture (though in the case of aluminum Hemalurgy, you would likely require an outside source to heal you, since your Invested healing just got excised by the spiking).

My goodness. Do you think that you could store the other Allomantic effects in their Feruchemical counterparts then? After all, the affects of Allomantic pewter aren't the same as Feruchemical pewter, but it might still work.

If a Bendalloy Misting can exclude specific objects and people from their bubble (as we see Wayne do), could a Cadmium Misting Savant exclude themselves from their own bubble? It probably wouldn't be quite as powerful as being a Slider, but it would be pretty close, especially since they already innately have the ability to make larger temporal bubbles than their counterparts.

WHAT. DUDE. Hold on a sec, does he mean that you can store the actual affects of Allomantic pewter, or that you can just store more of a Feruchemical charge than you could before? Because the way he says it makes it sound like the end result would just be a weaker form of Compounding.

I counted at least six Hemalurgic spikes that allowed for gold Feruchemy that were in the possession of the Set (Mr. Suit, Lady Kelesina, Telsin, the Cycle in TLM, Gave Entrone, and Gertruda). I know that they had quite a few resources at their disposal, but I was under the impression that Ferrings were rare, especially considering that if you wanted to get a specific type of Ferring for Hemalurgy, you have only 1/16th of the original number of Feruchemists to choose from. Not only that, but Mr. Suit mentions that the Set found a way to let someone else fuel their Hemalurgist's Feruchemy, probably via Identity blanking, which would suggest that they had even more Hemalurgic spikes providing health. How did they get so many Hemalurgic spikes providing gold Feruchemy?

I don't know if you can actually do that. Allomantic pewter enhances the performance of the body with Investiture and Feruchemy uses Investiture to actually increase the size of the muscles of the Feruchemist. I actually thought along a similar line a while ago, where perhaps the Lord Ruler had stored Allomantic power inside his Metalminds, which would explain why he couldn't still use his Allomancy to go retrieve them before age finally caught up to him. But everybody who talked on the forum said such a thing wasn't possible, and after looking at it again, I don't know if it's possible either; the attributes that can be stored in Feruchemy are just too different from the Allomantic powers for them to be stored most likely.

I'm confused. Do you mean using Feruchemical pewter to give him strength?

TLM spoilers

Absolutely. This would make mind-control a much more available option in the Cosmere. you could split a single spike into many smaller pieces. The only reason you normally don't do this with Hemalurgic spikes is because you loose even more potency when you do this. But if all you want is to open someone up to control or to cause them pain, that isn't any of your concern. I thought that it was more because the art itself disgusted him. But I could see him being worried about how powerful it might make some individuals with malicious intent.

But it only tells you what you would have done in a given circumstance, and doesn't therefore change the world you are living in. Even if you used this method with electrum or Atium, you would only see possibilities, which can be wrong, and therefore couldn't be an always-make-the-right-choice mechanism (though using the metallic arts to create Dallinar styled visions either of the past or the future would be insanely cool. Good quote by the way @Frustration) But if you just want to see what could have been, or if you want to live in something similar to very advanced VR, then yeah, I think that this makes sense. Edit: also, this is my 800th post!

I believe that Innate Investiture is actually a form of Static Investiture, as it is not currently being used. It does open up a small "window" to the Spiritual Realm though which energy can come through (like Rosharan spheres), which is how Feruchemy works; diverting the flow of said energy. I believe that the rest is accurate though. @alder24 brings up an interesting point: it may not be possible to affect all of a Feruchemist's attribute, as they aren't storing all of it. That being said, I think that this WoB says that it is possible to use Allomantic chromium or nicrosil on a Feruchemist, so long as they are tapping it. However, I can really only see that doing anything if you can affect all of the Investiture inside the Metalmind, even that Investiture not currently being tapped. This suggests that you could use Allomantic nicrosil or chromium on a Feruchemist who is storing, even if they aren't storing all of their attribute. So, my money is on the process working, though I am open to new developments in this area as we haven't seen it happen yet in a book.

But what about when Vin retains control of the Koloss, even though she isn't still using Emotional Allomancy? Isn't that a matter of Connection?

It might be better if you created a poll for people to vote too.

You're welcome I don't think that he could hold or use a Shard of Adonalsium very well yet. In fact, I would bet that the reason he can't use his Allomancy currently is because he still counts too much as a Spren-like being. But I don't know for sure yet. True. He seems to appreciate it when Shards do useful things for their peoples, but also likes it when the masses have power to act on their own, as shown by his desire to comedize Allomancy and Feruchemy. With that in mind, I think that Autonomy would be an excellent match for Kelsier.

Hmmm. That also might be pretty cool to learn more about (I totally forgot about that, actually).

HA! That would be awesome to see. Plus, Kelsier seems to fit well with Autonomy's Intent (or maybe it's just the Vessel's opinion).

In TLM, Gave Entrone somehow uses an enormous amount of strength to smash through a wall and attack Marasi. Allomantic pewter doesn't increase you strength by that much, and there was no description of him swelling with Feruchemical muscle mass like we see the Cycle at the beginning of the book. Did he perhaps have multiple spikes providing the ability to use Allomantic pewter, or is this our first example of a single Hemalurgic spike getting multiple doses of the same power imbued into it? It doesn't seem that unlikely to me. After all, the Set was experimenting with combining multiple non-Allomancers to create Hemalurgically granted powers, so deciding to use the same Hemalurgic spike to combine the power of two or more Pewterarms doesn't seem like that much of a stretch to me.

I meant more like rebelling against the Lord Ruler, and trying to build their own little personal army while he was alive. Ruin would squash the will even the most resistant Inquisitor without a care. We saw this with Marsh, actually.

I hadn't though of this till just now, but could a Steel Inquisitor or other Hemalurgist with four or more spikes avoid being controlled by others by storing their ability to form Connections to others via Feruchemical duralumin? After all, when Vin controls the Koloss she seems to do so by forging Connections to them. But if those Connections never formed in the first place, she wouldn't have been able to control them.

I wonder if any of the Steel Inquisitors realized that they could use Emotional Allomancy to control one another, and if so, if there ever was a case of Steel Inquisitors rebelling against the Lord Ruler. Also, if a Steel Inquisitor had the mind to, couldn't they have created another Inquisitor on their own (assuming that they could find enough Mistings) and controlled them to do their every whim, and prevent them from controlling their master by not giving them Emotional Allomancy? Just a thought.

HAH! True.

Ah, that makes sense I suppose. For Steel Inquisitors specifically though... TLM spoilers Which probably explains why the Steel Inquisitors could be blinded by the metal dust in TFE. Ironically, regular Steelsight would actually be better in this circumstance, if I understand correctly, since they couldn't push on the body of their opponent (or even their internal metals), but they might still be able to sense their internal reserves. Steel Inquisitors probably couldn't though.

Oooooooh. Hadn't thought of that. Though, I doubt that momentary lack of most Feruchemically viable attributes would prove fatal. I think that strength could be fatal if your heart doesn't start up again automatically. No energy means death for certain. Health would possibly kill you, but it might just mean that your immune system doesn't work for one brief moment, which likely wouldn't be that dangerous. Whether cadmium kills you or not depends on whether you can store the oxygen that is already being used by you cells and how long it would take for you to breath in more. Storing youth would probably kill you, as you might just turn into a pile of dust (does the dust turn back into your corpse afterward, since it's a temporary change? That would be weird).

What about when Vin busted into the Lord Ruler's palace at the end of TFE and blinded a pair of Steel Inquisitors with metal dust? They couldn't see through a surface that was visible to them, which means that you shouldn't (under normal circumstances) be able to use Steelsight to x-ray vision through something else that is viable to Steelsense.

So then, if you doubled up a Feruchemist's power with a Hemalurgic spike of the same power, you would get a more efficient version? That's kind of cool. I remember questioning this awhile back on the Q&A, but this seems like it explains it pretty well. This would also explain why Steel Inquisitors needed more time to store health that natural Feruchemists; it wasn't that they couldn't store as quickly, they just didn't get as use out of the amount of Investiture they stored.
