I recently made another thread on how one might be able to use specific Rhythms of Invested powers to program the Investiture and make that power usable for things like Feruchemy (although TLM shows Unkeyed Dor, which works just fine for any Invested power, so this strategy of programming isn't all that useful). However, I now wonder if it would be possible to take a Hemalurgic spike powered by non-Metalborn and use a combination of Rhythms emitted by Invested powers and Intent to program the spike to have the power you want. My thinking of how someone would go about creating Hemalurgic power spikes from non-Metalborn currently looks something like this. 1. Use Hemalurgy to take an Invested charge from a person. A. Make sure to either give the donor access to F-aluminum (via Hemalurgy or Unsealed Metalmind) to blank their Identity while you harvest their Innate Investiture (so that it can be combined with other donor's Investiture; Identity contamination is a real thorn in the side if not handled properly) or give the donor access to F-gold (with lots of stores saved ahead of time) to replace lost Spiritweb fragments. Identity-blanked Spiritweb fragments may also be more susceptible to being programmed (as a Feruchemist blanking Identity is susceptible to "all kinds of things"), so even if you provide them with F-gold you may also want to give them F-aluminum anyway. B. Also, make sure the spike is made of the right kind of metal to properly channel the Investiture (i.e., if you plan to program it with A-pewter, use a steel spike for physical Allomancy), otherwise you'll end up with the same kind of situation if you alloyed an Invested Metalmind into another type of metal (Investiture is there, but can't be accessed). 2. After sufficiently charging the spike, use Navani's method of changing an Investiture's Tone but instead learn and use the Rhythm (the pulse that A-bronze can sense) of the Invested power you want the spike to have. A. Might have to be a very skilled Seeker to achieve the necessary insight. It might also help to travel to Roshar and Hemalurgically take Connection from a Singer, but that may not be strictly necessary. 3. Now that the spike has been charged and exposed (with Intent) to the Rhythm of the power you desire, it should change its function to grant the power you want.

So my brain spawned yet another way to hack magic systems together to make them even better Let's say that you use Forgery to overwrite a Koloss Spiritweb, saying that it never received its Hemalurgic spikes. I see a few possibilities if this were to be done: 1. the Koloss dies as they turn back into a human; their spikes no longer function well enough to prevent the wounds they inflict from killing their bearer. 2. the Koloss turns back into a human, but the Hemalurgic spikes resist and are rejected from the body (as the Koloss's body fights against their intrusion) if the Forgery takes; the changes made by the spike and the changes made by the stamp are too incompatible with one another to exist with any sense of stability. 3. the Koloss turned human retains their spikes without dying (the soul of the recipient adapts to their Investiture, similar to Feruchemy adapting the Feruchemist to deal with an unexpected influx of attributes), but the spikes remain completely dormant and don't give any additional benefits until the Forgery wears off. 4. same as #3, but the spikes continue to provide a magical boost to the former Koloss but don't warp them enough to turn them into a Hemalurigc construct- just enough to keep the person from being killed by the spikes. The reason I even argue that this could take place is because Returned can do something similar; they can suppress their Divine Breath but still retain some benefits from it, such as enhanced speed and strength, and their Lifesense doesn't disappear (see Zahel in WoR when Kalain wakes him up at night). Basically, you might be able to use Forgery hack Hemalurgy in such a way that you could give humans Kandra Blessings but without turning them into Hemalurgic constructs (Hemalurgic weakness likely would remain though; the cracks in the Spiritweb aren't removed as far as I can tell). Now, as I understand it this might require some "jerry-rigging" of sorts, but I believe that it might be possible given the examples above.

The title says it all. To elaborate, I'm wondering if it is at all possible to use Emotional Allomancy to control an Inquisitor through the cracks of their Spiritweb, given that we have never seen it done before. Granted, there are some good reasons for this. Practically no one knew about this "Hemalurgic backdoor" and the ones that did couldn't and/or wouldn't try it. By the time this was discovered, Ruin had escaped, and no one could contest a Shard's hold. Inquisitors had access to Allomantic copper, possibly multiple times over, which was an excellent counter. Inquisitors have sapience and willpower, and if the Allomancer fails, Adonalsium have mercy upon them. I'm wondering if I have some of the facts wrong, or if there's a reason all its own for this to never happen. Otherwise, to cover all my bases, let's assume a group of several Soothers (or Rioters, but for the sake of argument, Soothers) with several Nicrobursts got together Post-Catacendre, and tried to overwhelm Marsh's copper and willpower with a combined Push. Excluding divine intervention, is there any reason this would not work?

Through my re-read of TLM, I noticed a few things. One of which was that Gave Entrone was a high-ranking Set member (at least he seems to be), and seemed to have access to Allomantic pewter, Feuchemical gold, and because of the special lock in his house it seems likely that he also has both Allomantic steel and iron. He has four powers granted by Hemalurgy and is hit by an enormous wave of Emotional Allomancy fueled by purified Dor, but isn't controlled by the Allomancer. This means that Trellium Hemalurgy isn't just a "smokescreen" from Shards, or a severing of Connection to the Shard (removing the "bridge" between the Hemalurgist and the Shard in question) that prevents Shards from controlling the Hemalurgist (as I had previously thought), but that it is a protection that no one can breech to control them (with the exception of Autonomy, likely because it is her Investiture protecting the Hemalurgist, and therefore her control isn't considered a "hostile Investiture"). I believe that @alder24 originally came up with the idea on another thread talking about Trellium Hemalurgy's mechanics about how Trellium Hemalurgy protected Hemalurgists from being controlled by "filling" the cracks in their Spiritweb made by the Hemalurgic spikes with Autonomy's. I now believe this to be the case. Autonomy's Investiture repels other sources of Investiture, which is probably why even Shards and hyper-powered Allomancers cannot control Hemalurgists pierced with four or more spikes so long as they are also pierced by a Trellium spike. It isn't a merely a matter of Connection to the Shard, but a filling of the cracks in the Spiritweb with an Investiture that repulses other sources of Investiture seeking to get inside (it should be noted that a Shard would still need sufficient Connection to a Hemalurgist to control them- . i.e., Odium couldn't just take over someone sufficiently pierced by Hemalurgy who visited Roshar- but Trellium's method works differently all together). Which is even more interesting than what I thought before, since the strength of Investiture held within a Trellium spike and a Shard seeking to control the Hemalurgist clearly isn't even remotely equal. But somehow, the strength of the being trying to control the Hemalurgist doesn't matter at all when compared to what a Trellium spike's effects, suggesting that it isn't brute force shielding the Hemalurgist's soul by repelling other sources of Investiture, but an actual fiddling with the mechanics that would leave a being susceptible to being controlled.

I was re-reading TLM when I noticed something that I had overlooked before. Dumad, the Sequence trying to copy Wax, has five Allomantic powers. Wax comments on his skill and considers that he might be a naturally born Coinshot because of this. Previously, I had assumed that this was probably the case, but as I re-read the section where Wax and Wayne spike themselves I saw that Wayne took Dumad's steel Allomancy, meaning that it had to be provided by Hemalurgy. This doesn't necessarily mean that he isn't a natural Misting, but now we know for certain that he isn't a natural Coinshot and therefore great skill with any of his particular powers (such as his Allomantic bronze) doesn't mean he is a natural Misting. This also may mean that five spikes may be the upper limit to what modern Hemalurgy can provide, not four.

We know that if you pierce your body with Metalminds then if you get Leeched your Metalminds also get Leeched away. But we also know that Hemalurgic spikes are immune to burned aluminum, which used a similar mechanic. And then, we also know that you can double your Hemalurgic spikes as Feruchemical storages, with the Investiture of both aspects being stored in different parts of the metal. SO, in conclusion, I see two possibilities: 1. If a Hemalurgist uses one of their spikes to double as a Feruchemical storage and they get Leeched, the part of their spike containing a Feruchemical charge gets burned away. This could be interesting to see, particularly since Hemalurgic spikes do not contain much Investiture within them typically. Just enough to "hotwire" the Spiritweb and grant powers or enhanced attributes. So it may be possible to use this method to minimize the size of your Hemalurgic spikes while providing the maximum Investiture such a spike could hold. Alternatively, you could use this method to test the actual amount of metal required to hold a Hemalurgic charge of a certian amount. 2. If the spike does not burn away when Leeched, then Hemalurgists actually have an advantage over natural Feruchemists in this area; other Feruchemists must either leave their Metalminds at least somewhat vulnerable to Steelpushing and Ironpulling or they must leave them vulnerable to being Leeched out of their bodies, but a Hemalurgist using a spike as a Metalmind has the best of both worlds. 3. If the Feruchemical charge is pulled out of the spike but the metal of the spike remains intact, then at the very least the Hemalurgist doesn't need to worry about getting more Metalminds, though they don't have any other cool advantage or unique mechanic.

So, I'm almost certain others have theorized this already, but after some extensive searching, I was unable to find anyone on here who did. So, here we go. In Epilogue 7, Marsh approaches Wax, Steris, and Marasi before Wayne's statue. When asked on how he walks about without drawing attention, he passes it off as emotional Allomancy. Still, Wax expresses his doubts. I think all Cosmerenauts on all worlds stirred in their beds with that phrase. But regardless, this moves on to my theory. I think Marsh moves about unseen through a combination of emotional Allomancy... and Feruchemical duralumin. To quote from the Coppermind, Feruchmeical duralumin functions as such. This seems a very likely explanation for that "something more" Wax postulates. Granted, don't know if Marsh was given spikes following the Catacendre, and there is no way of knowing if Rashek was aware of duralumin's Feruchemical properties. Still, he was a Feruchemist himself, and discovered duralumin. It makes sense he would test it. Anyway, there's my three cents. Thoughts? ~Longshot97

I have an idea. Since hemalurgy can be used to steal Connection, could one use hemalurgy to steal an Elantrian’s Connection to Elantris, then give that Connection to another person? In addition, could one give said Connection to a Dakor monk, and how would Aon Dor interact with the monk?

I found a quote that may have some interesting implications. Except, we don't see Miles exhibiting any extra powers from Hemalurgy, and we know that Miles likes to pierce his own body with gold spikes (not Hemalurgic ones) to act as Feruchemical storages. For reasons seen in TLM he may have a single Hemalurgic Trellium spike, but one spike is never enough to control a being. I think that it may be possible that if someone pierces their body with a Feruchemically charged metal, it may allow external forces to influence, maybe even control them similar to Hemalurgic spikes (though you may need far more Metalminds than spikes to achieve this effect). Investiture exists in all three realms, so if an Invested metal pierces your body, maybe that opens a hole for other things to get in, though likely it wouldn't as pronounced with Feruchemy as with Hemalurgy. TLR also may have inadvertently made himself more vulnerable to Ruin's influence by doing this, especially since Atium- Ruin's own essence- was what his primary Metalminds were made of.

In a previous question, a person asked whether or not a person could Awaken a piece of steak and then stab it with Hemalurgy to produce a proto-Human. In response Brandon replied that was plausable but soulcasting would be better. Using this concept I thought that perhaps, using soulcasting to carve or create a body then stabbing it with a Hemalurgic spike you could perhaps create some form of clone. But then I considered the possibilities and then realized how insane you could get with concepts such as this and how you could possibly make entire new species if done well enough. So reply and say your crazy ideas with all of this

This was inspired by a comment by @IlstrawberrySeed the thread "how to become ludicrously strong". A Kandra can shape its body pretty much any way they like, so long as it obeys the laws of physics (i.e., they can't go too big since it would crush them and they can't go too small because they need enough mass to support cognitive functions). Therefore, you get a two-hundred-ton sphere of nicrosil, might need Soulcasting, put a (relatively) small amount of Identity-blanked Feruchemical nicrosil in it to reprogram the potential Invested output (it spreads out like a gas, so you don't need a ton), and have the Kandra engulf it like an amoeba. Then, you give the Kandra access to Allomantic nicrosil as well as Allomantic duralumin via Hemalurgic spikes. Now the Kandra burns the metal- with the aid of duralumin- gives themselves insanely large quantities of Investiture. Hopefully, the Kandra will ascend (similar to the Well of Ascension) and briefly become a god. Plus, since you gave the power to burn the nicrosil with Hemalurgy, they will most likely fuel their Ascension with Ruin's Investiture. So basically, that's how you create an invested meatball-god of death! A way to improve this would be to increase the potency of the Hemalurgically granted A-nicrosil. Probably stacking multiple Identity-blanked Hemalurgic charges together in the same spike so that the amount of Investiture the Kandra gets per the amount of metal is increased.

Can you steal ANY ability like sand mastery or surges?

We've seen with Bleeder and with Set members that Trellium can be used to Hemalurgically grant someone Metalborn powers, but we've also seen that it can be used to create Hemalurgic constructs- the Chimera- which is normally only doable with human attributes. I wonder then, if the Bindpoint placement is even more important than I had previously imagined. Could you perhaps keep someone a human while using Hemalurgy to staple on extra human attributes, since it seems that you can do the opposite- staple the portion of a Spiritweb meant to grant powers to someone else onto a human and turn them into a Hemalurgic construct?

I've actually been wondering about this for a while now, and actually did come up with a post about it long ago, but I think that I may have changed my mind on the concept. Hemalurgy is a fascinating thing in the Cosmere, and it has lots of potential. But would it really be the best thing to practice openly on Scadrial, or anywhere in the Cosmere? Hemalurgy can; (1) grant powers to people of your choice, (2) take powers from those of your choice, (3) transform people into different kind of creatures. Power granting: With this ability, you could give your constables Invested powers, such as Allomantic pewter, Allomantic steel, or Feruchemical gold, making them much better at their jobs. You could also give certain other government officials powers to improve their jobs, such as Feruchemical copper, zinc, or bronze. This should increase their efficiency, which would then improve their society. If people got too selfish or irresponsible with their newfound power, you could remove the spikes and give them to someone else. However, a better alternative seems to already exist. Malwish Medallion tech also provides Invested powers and does not need to rely on Hemalurgic spiking to do so. It would also be easier to remove a medallion from an abuser, since they need to be recharged. Hemalurgic spikes do not, and they also cause pain to the donor and the recipient. This brings us to out next issue. Power removal: Using Hemalurgy, you can remove powers from Metalborn who abuse their natural talents and recycle them for something (hypothetically) good. Many outlaws exist in the Roughs who have access to the Metallic Arts, and having the very real threat of having their sticks taken away from them might push them to shape up. However, this could end up doing even more bad than it solves. When you introduce motivation to place blame on someone with a natural advantage, one that you might possibly get to have if they lose it, you will undoubtedly see people in positions of power abuse the laws that make it possible to steal other's Investiture. This doesn't just apply to government officials either. If Hemalurgic spikes were to become monetized rather than simply being a tool for the government, the rich would almost certainly be the ones to benefit, since they have the actual means to grab such powers; you wouldn't be putting power in the hands of the people, you'd likely end up putting even more power in the hands of a handful of privileged nobility. It's true, you could have people voluntarily give up their powers to trusted individuals or desendants if they were terminally ill, or perhaps if you found a way to non-lethally remove powers, but you'd have to be careful not to abuse such an occurrence. Transforming people: This is probably the least useful aspects of Hemalurgy, at least as it stands now. If you've read Shadows of Self... it's hard to forget the Chimera. That is evil. There just isn't a good way to use that application of Hemalurgy. Now, I could see the analytical insights provided by Hemalurgy's mechanics being used in a beneficial manner, but only if controlled carefully. It would be like CRISPR in the Cosmere, or at least researching Hemalurgy could lead to such knowledge. That is useful, and I think could be worth pursuing. It would likely require access to the Spiritual Realm to achieve any useful insights in this area though, but such a thing wouldn't be unattainable to those with the resources and knowledge. My conclusion: after considering all of this, my personal thinking is that knowledge of Hemalurgy should become widespread but should have strict laws placed upon its usage. Then, any secret organizations like the Set cannot use it as effectively since awareness of its existence will be common knowledge, and research into its uses for Spiritweb manipulation could be pursued on a societal level. I no longer think that powers should be regularly given and taken though, and Scadrial's laws should reflect such; it's just too easy to abuse, and Unsealed Metalminds seem like a better alternative to granting Invested powers to more people anyway. I think that power donation via Hemalurgy could still be useful in certain individual cases (Wax, Wayne and Marasi could use a power-up by recyling Set agent spikes to better deal with the rest of the Set, for example), but on a societal scale, it isn't something I'd hazard. What are your thoughts on the matter?

We still haven't seen any Hemalurgy of the spiritual quadrant at work. I really, really want to know what these things do though. Unfortunately, this seems unlikely until Brandon Sanderson decides it's time, but for now I will settle for educated guesswork. Here's what I think with my current, limited knowledge: Hemalurgic aluminum: Pretty straightforward, we know it removes all Invested powers from someone, but since it's aluminum, it doesn't keep the Invested charge and the powers are effectively destroyed. I am extremely confident in this particular take on this particular power. The next three are assumptions with what I feel is good reasoning behind them, but are to be taken with a grain of salt until they are proven (or disproven) to be the case. Hemalurgic nicrosil: Steals Investiture. It was mentioned by Sanderson that this is referring to raw Investiture rather than it being a "wild card" and taking any power like Atium. I assume from this that you could give someone Heightening-like effects from Hemalurgic Nicrosil, though unless you found a way to increase the number of charges you could put inside a spike, it wouldn't be very useful (you might be able to do this by Feruchemically blanking the Identity of the donor). What would be most interesting about this though, is that it is a human attribute, not an Invested power. Because of this, it would likely twist you into some inhuman creature, similar to a Koloss or Chimera. So, if someone ever learns to use Hemalurgic nicrosil to extend their lifespan, Scadrial might have a new race of creatures that are a bit like vampires: once humans who gave up their humanity to become effectively immortal. Hemalurgic duralumin: this allows you to take someone else's Identity and Connection. This is a bit confusing, since all Hemalurgy takes a portion of someone else's Identity along with the Power or attribute. I think that it might be done more wholly in this case, perhaps because Connection and Identity are more closely related than we'd once thought? In any case, I think that the Connection part might be useful for transferring skills (similar to Selish Forgery), known languages (like the Malwish medallions), emotional bonds, or even one's tie to time of birth, which might be useful to reduce one's age, but without needing to Compounding Atium since you own Connection to birth would balance with the new Connection, perhaps giving you some kind of "median age" that you'd become. You'd still age, but you could replace the spike with someone else who was youthful eventually (actually sounds a lot like a vampire now. Also, quite possibly evil). The Identity portion might also have some interesting consequences. We know that Singers can change their forms by toggling their Identity via Spren Bonds, so perhaps by using a duralumin spike you could change your race, biological sex, or other facets of your appearance. It really depends on whether you would get extreme changes like we see with most Hemalurgic constructs, or if it works a bit differently for duralumin (which we don't have proof for yet, but Sanderson has done things like this before, such as with aluminum Allomancy or copper Feruchemy; some powers work differently, mostly just because it follows the rule of cool). Hemalurgic chromium: the only metal that we're told only might do something; steal destiny. My current assumption is that this somehow works by manipulating Fortune, which is some kind of "gut feeling" that every person has. I think that Hemalurgic chromium takes someone else's Fortune, but since it has actual pieces of their Spiritweb, it has portions of their Connection and Identity, that it is still "shaped" or "directed" along the same path the donor would have been nudged to take. Perhaps this mean that the Hemalurgist with the new spike would get gut impressions to do things the other person would do, but their own destiny would interfere and push them to make other decisions and their memories, personality, culture, and previous life choices would interfere, altering the path of said destiny. this means that you could try to steal someone else's destiny, but it isn't guaranteed, since destiny is tied to personal choices, past, and location as well as instincts. This is definitely to be taken with a grain of salt though, since we don't have a clear idea of what Fortune really is yet. In any case, these are the headcannons of mine as to what the spiritual Hemalurgic metals can do. I'd love to hear what all of you guys think though, and am open to new ideas as to their functions!

Not once in era 2 do we see a Set member using a Hemalurgic spike that granted Feruchemical steel (Paalm doesn't count; she allied with the Set, but wasn't an official member). There were only a few known Steelrunners that Vwafendal had known about (was it three?), but even with Idashwy's power taken by Paalm, wouldn't the Set have had at least one or two Steelrunners available to spike? It's not like they didn't know how to access rare Feruchemical powers either: their small pile of Hemalurgic spikes providing Feruchemical gold prove this. It just seems like such a potentially powerful ability that the Set would have been absolutely giddy to get their hands on it. So why didn't they?

Reposting my post here from reddit, just cause. I write these words in steel this post because I've been thinking about it more than is probably healthy and needed to put it up somewhere. The problem is that Allomancy and Feruchemy are rare and genetically derived, which limits Scadrial's growth and security. And, I'm growing increasingly certain that the best way to achieve Kel's goal of democratizing access to powers is with this new way of performing Hemalurgy the Set discovered. What we actually see and know for certain is that the Set made Hemalurgic spikes through a non-lethal, accumulative way that briefly granted the bearer powers. They did so by spiking the extra bit of Preservation from people's souls and, somehow, coding(???) the spike with a power. Shai then speculated that since they can charge spikes with raw Preservation from souls, it should be possible to create them with raw Investiture, pointing towards the jar of purified Dor while saying so. From here, we can speculate that the following might be possible: Creating Kandra Blessings through the same method the Set used. Potentially creating Kandra Blessings entirely from scratch through the method Shai theorized. Recharging decayed spikes with raw (and likely purified) Investiture to maintain the strength of the power they provide. Potentially overcharging Hemalurgic spikes to grant a stronger power than what it stole. A partially charged spike might still be used to grant a weaker power. The Set seemingly used only the spikes charged to 100%* but I don't see any compelling reasons why it would be a requirement. The problem with the existing method is that it's yet to successfully grant a power and Shai was just speculating. But Realmatically we have several issues: Identity contamination. As mentioned by Marsh earlier in the book, this might be a reason why the method fails — the power granted is keyed to a weird Identity mash that a bearer has trouble accessing. Fundamentally, Hemalurgy is about taking something away. While the end-negative/-positive classification became less useful as time passed, I have trouble believing that it can be hacked to an extent that the main Intent behind the magic is completely sidestepped. According to Ars Arcanum, Hemalurgic decay no longer exists, making the recharging idea irrelevant. Note: it is unclear which of the two decays Khriss meant (spikes losing power over time when not in a body/a steak or spikes having a weaker power in a recipient than a donor). While we know of a few man-made items that overshadow traditional Hemalurgy and Feruchemy in terms of Investiture density(Nalthian Blades and maybe Bands), we know nothing that suggests that the extra power would augment the Hemalurgic part of the spike instead of sitting beside it. Creating spikes from scratch seems too simple. And judging how wrong many of us were about the Medallions, there might be more to it than it first appears. What I propose is a mixed method of the perfected technique the Set used and Shai's theoretical one. You take the extra Investiture from a person's soul (what Kel called the "heart of Preservation") in a spike just like we saw in the book. Then, you charge the spike the rest of the way with raw/purified Investiture, code a Metallic Art into it, and give this spike to the same person - completely avoiding Identity contamination. The good (if it works, obviously): Completely democratizes Metallic Arts. Any non-Metalborn can become one. Society, politics, money, scarcity, and other similar problems will obviously prevent everyone from getting powers, but depending on how available the Investiture will become I'm confident that Scadrian society can get to a point where all educated professionals can get a spike after finishing education/graduating from uni/college/academy/etc. Spikes accumulate after their bearers die and can be reused by future generations. Bearing a spike shows one's devotion to Harmony, Death, and Sliver. People finally get to choose what power they get. Completely circumvents the genetic aspect of the Metallic Arts. Can be fully automated with sufficient technological advancement. We don't have surgical robots this good, but we aren't far from making one. Especially, since the procedure isn't that complicated. Note: I assume here that Hemalurgy can be automated similarly to how Brandon said making Soulstamps can. Will publicize Heamlurgy as an Invested Art, which will lead to a deeper understanding of souls in the cosmere. The bad: Still adds to social inequality through corruption, inheritance laws, and economic inequality. Will publicize Heamlurgy as an Invested Art -> people will be killing one another to get their powers or steal their spikes. -> Mistborn serial killer Gives Harmony/Discord a way to your soul. Will popularize piercings. Thoughts and ideas are welcome.

We know Feruchemical Tin can store Allomantic senses like Bronze NewbSombrero Can Feruchemical tin store Allomantically granted senses like bronze sense? Brandon Sanderson Possible. General Signed Books 2018 (Feb. 8, 2018) Theoretically, Hemalurgic tin should store all the same things as F-Tin. So if you had proper Intent, could you spike the bronze sense out of an Allomancer burning bronze? If you did, would the recipient of that spike have permanently renewing bronze sense, much like regular kandra blessings (including Tin), or would it have a limited duration because the bronze wasn’t a natural sense?

I’m re-reading Shadows of Self, and I’m wondering: What could be accomplished with Hemalurgic Bullets. One such bullet put Pa’alm back under Harmony’s control, but perhaps you could accomplish other things. For instance, multiple bullets could make a normal person into someone susceptible to control via emotional allomancy. Or, with Hemalurgic Aluminum bullets, you could become a complete bane to an invested opponent. Rusts, use those for firing squads against people like Myles Hundredlives. I’m starting to see why Harmony wanted to keep a lid on this stuff. I’m thinking for Hemalurgic control, you use shot gun rounds in Alluminum casing. Preserves the Hemalurgic Charge, and allows for multiple piercings, facilitating better control. That would probably work well for Hemalurgic aluminum too, as it means you need not be as accurate. Of course a Hemalurgic Aluminum Sniper Rifle could be a powerful weapon for someone who wants to drop an invested high value target. I’d say this prohibitively expensive. Not to mention all the people you’d have to kill in order to get a decent ammunition supply.

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 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.

One of the interesting things about Investiture is that the Intent of what Investiture you are using matters. For example, you can only alter yourself so much with Awakening's standard system because Endowment's Intent permeates the Investiture you are using. I think that if you could find a way to craft an Invested power from Endowment's Investiture then, you may be able to transfer it as you would BioChromatic-Breaths. Here's a method that I thought of. Step one: get an Unsealed Metalmind that provides the ability to use Feruchemical gold and aluminum (health and Identity) or a pair of Hemalurgic spikes that provide the same powers. Step two: give the powers to a willing Nalthian who then stores a ton of health while blanking their Identity. NO COMPOUNDING. The health must come from the Nalthian's own Spiritweb. Step three: excise the Invested power of another willing individual via Hemalurgy without killing them (probably an Allomancer or Ferring, though it may be that other Invested powers that are innately part of someone's Spiritweb could work). Step four: have the donor tap the healing from the Unsealed metalmind (or Hemalurgic spikes) to replace the power. And at this point, it is important to know that when you heal a part of someone's Spiritweb, you actually graft an entirely new piece of Investiture on. And in this case, that Investiture came entirely from Endowment, as Nalthian's Spiritwebs are made up entirely of her essence. So now we have an Invested power made up entirely of Endowment's Investiture. This may mean that you could transfer it as you could normal Breaths, though you may have to Connect the donor to Nalthis in order to gain the ability to do so. If this is the case, you could create very powerful individuals, but without the vulnerabilities and limitations of Hemalurgy- though the powers may be able to be drained by things like larken and chromium Mistings, but I'm not sure; this is entirely theoretical. Let me guys know what you think!

In The Lost Metal, we see that Trellium spikes are used by Set Members to sidestep being Controlled by Harmony, but they are still able to be controlled by Autonomy. We also see that Allomancers with Trellium spikes are still able to use Allomancy, which is powered by utilizing a Connection to Preservation to draw on Preservation's Investiture (or possibly Ruin's, if the power is granted by a Hemalurgic spike). This left me confused, since an individual would need a Connection to Harmony in order to utilize their powers, but that leaves them open to influence and even outright control if they bear more than three Hemalurgic spikes. Trellium must then, I figure, rewrite one's Connection, transferring it from whatever Shard they were Connected to before and Connecting them instead to Autonomy since an individual must be Connected to something. The Set's Allomantic powers are probably powered entirely by Autonomy's Investiture, since Allomancy would still need a Shard to fuel them, and those pierced by Trellium wouldn't be Connected to Harmony anymore, and thus wouldn't be able to draw on its Investiture. I bet that if this is the case, Trellium-other Godmetal alloy would rewrite one's Connection to any Shard that the Trellium was alloyed with, similar to how Lerasium can grant a Connection to and powers from any shard when alloyed with that Shard's metal.

In The Lost Metal, Marsh states that Identity contamination prevents the Set from compounding. I wonder, then, if you could overcome this limitation by having the donor blank their Identity via Unsealed Aluminumminds, or via a Hemalurigc spike. This also makes me wonder why it is that Marsh can compound, even though he doesn't (presumably) have Identityless spikes. Did Hemalurgic spikes just permeate the Spiriweb more in Ancient times, and now the spikes are more "contained" within their separate Identities? I know that we have the Ars. Arcanum, but I'm just curious about the mechanics of Hemalurgy's change, and how they can be overcome by a clever individual (not that I personally claim to be such an individual, just a curious one).
