Kurkistan

If you spiked out Miles' Feruchemical gold, would he be able to burn his Allomantic reserves [read: Feruchemical reserves using Allomancy] and heal it back?

Brandon Sanderson

If you spiked out his ability to heal gold and somehow left him alive?

Kurkistan

Yeah, but still having Allomancy.

Brandon Sanderson

Still has Allomancy...

Kurkistan

And he’s like in the middle of burning a goldmind.

Brandon Sanderson

Yes, that would still work. It'd still have a Spiritual Connection to him.

Kurkistan

So if you're a Coinshot and you get [spiked] to have Feruchemical steel, and then you lose the spike after making a store, you can still Compound that for speed?

Brandon Sanderson

Yes... Yeah, that should still work.

Kurkistan

Was Paalm doing that?

Brandon Sanderson

That's a RAFO.

Questioner

Can Shardblades, dead or alive, be used as Hemalurgic spikes? And if attempted, what would the result be?

Brandon Sanderson

Technically yes, but in practicality no.

To use something as a Hemalurgic spike, it basically just needs to be able to already have a charge of Investiture, or be able to adopt one. Technically, Shardblades are made from a god metal. You could do this. But the Blade is gonna be big and unwieldy, and the form it’s in right now, it’s going to slice the soul rather than rip pieces off. You would have to jump through a bunch of hoops that wouldn’t be worth it in order to use one.

It would basically mean that you’d have to separate the metal of the Shardblade from the concept of a Shardblade itself, is what’s going on there.

Returned Feeding Mechanics.png

Haverworthy

Just had a question, when a Returned consumes a Breath, is it a property of their body that does so or the Divine Breath itself? It's been contentious in the community. If it's specifically just their body and a hemalurgist were to spike a Divine Breath as indicated was possible here*, would the hemalurgist not need to consume a weekly breath?

*https://wob.coppermind.net/events/364/#e11389

Brandon Sanderson

That's a very interesting question. The thing that requires the Returned to continue gaining investiture is their nature as cognitive shadows--they are dead, and in this case, need a power source to continue persisting in the physical realm. The Divine Breath is part of this. Imagine the Divine Breath as the thing that Infuses their soul, making it persist initially, and then and sticks it to the body. So if you stole it, but you yourself were not in need of being kept alive, I would say that you wouldn't need to be fed a new breath each week to maintain the Divine Breath.

Argent

On Nalthis, can aluminum prevent somebody from Returning? So if you kill somebody with aluminum and leave the weapon in them?

Brandon Sanderson

I don't think that's going to be enough. I think that…

Argent

Different way then?

Brandon Sanderson

Yeah there are totally ways. I don’t think that that’s going to be enough. There's a difference between being inert and blocking Investiture, and actually sucking out Investiture. If you stuck Nightblood inside of a corpse; there are certain things… if you had a larkin or whatever sitting there that ingests the Investiture as it was coming in, that would prevent [Returning]. I think with aluminum you would just have somebody that comes alive with a wound, so maybe... But I think it would just heal around [the aluminum] and you'd just have a spike in you, kind of like Hemalurgy—but not like Hemalurgy. It's inert, but you know what I mean.

Argent

Which suggests you can't actually Awaken aluminum.

Brandon Sanderson

No. It's not going to hold a charge.

Kurkistan

I assume you can't Forge it, either.

Brandon Sanderson

No. In fact the unForgable metal-

Argent

Ralkalest?

Brandon Sanderson

There's an unForgeable metal mentioned.

Kurkistan

Could we call it aluminum if we wanted to?

Let's just say that aluminum through most cultures was considered a mythological metal, and when people could actually find some, they considered it more valuable than gold, in our culture. So just sayin'...

Ilkhan2016

Breath and Stormlight are both forms of Investiture. AFAIK you can power any of the magic systems from any form of Investiture. Zahel is on Roshar, I believe, primarily due to how easy Investiture (Stormlight) is to come across.

AFAIK the form of Investiture doesn't change anything about the abilities. For example, Szeth was sucked out of Stormlight when he drew Nightblood; and Azure used Stormlight to Awaken in Shadesmar.

/u/mistborn is that right?

Brandon Sanderson

A lot of this depends on the Investiture and the magic in question. Azure was legit using Breaths, for example--ones she'd brought with her. But Szeth was able to feed Stormlight to Nightblood, much as Vasher uses Stormlight to keep himself alive.

To Awaken with Stormlight, the easiest thing to do would be to first change Stormlight into Breaths--something that Azure doesn't know how to do. (Admittedly, Hoid doesn't either, so it's not like it's a simple thing to achieve.) You could also theoretically use some magical (or mechanical) means to power your Awakening with a different form of Investiture.

Extesian

This is very interesting. Is it possible then in the Cosmere for the 'intent' (spin or however described) of Investiture to be changed? And I mean within reasonable limits (not the powers of six shards or any of that). Can a Shard effectively grow in power in a place (e.g. toward an avatar) through another Shard's Investiture being changed (not just corrupted)? Or is it just making one type ('intent' - you should canonize a word for this :D) of Investiture mimic the properties of another?

Brandon Sanderson

Most of the ways of accomplishing what you're talking about would involve either 1) fooling/overwriting your spiritual makeup somehow. (This is what Hemalurgy does, for example.) 2) Refining the power somehow into a more pure form.

But there are a lot of variables. The way magic from Nalthis works, for example, the system is just looking for any available Investiture to power itself--and so basically anything will do, regardless of the source. This includes consuming your own soul, in some cases...

You'll see terminology coming along eventually that facilitates talking about all of this. I'm not yet decided on some of it.

Celestial_Blu3

How many Breaths does [Azure] have by her final appearance in OB?

Brandon Sanderson

That's a RAFO, I'm afraid.

Pagerunner

The Hemalurgy table, you wrote down "atium steals any power, lerasium is all abilities, nicrosil is Investiture"; what's the difference between those three?

Hemalurgic atium, lerasium, and nicrosil. What's powers, abilities, and Investiture?

Brandon Sanderson

People are Invested in ways that do not give them active powers. So for instance, everyone on Nalthis is Invested. Everyone in the cosmere is, really. You want to steal their Investiture, but they don't have a power. You're still ripping off a piece of their soul. So there is a distinction between the actual Investiture that's in a human being and a specific power that they have.

So that distinction is pretty easy. You can also, with Hemalurgy, steal specific things. You can steal just general Investiture. You can steal, if you want--this is where the kandra Blessings come from. You can instead steal specific things that are not like stealing Allomancy. Stealing, for instance, someone's mental acuity.

Pagerunner

So abilities is like the half that's all the strength, speed, all that kind of stuff? Those are abilities, versus the Metallic Arts are all powers?

Brandon Sanderson

Yes.

Pagerunner

Then Investiture, is that offworld magics?

Brandon Sanderson

No, no, it's the raw power.

Pagerunner

Nicrosil is their soul?

Brandon Sanderson

Yes. A piece of their soul, essentially.

Pagerunner

So how would you go about stealing an offworld power?

Brandon Sanderson

It's going to depend. A Breath, you would steal with nicrosil. It's general Investiture, is what you would probably going call that. You could forcibly remove someone's Breath from them. The ability to be a Sand Master you would steal with the power ability.

ElephantEarwax

Are there any Hemalurgic bind points in the mouth or digestive tract?

Brandon Sanderson

Eh. *laughs* Why do you want to know this? 

ElephantEarwax

...We're trying to make sure we're doing it right.

Brandon Sanderson

The Hemalurgic table will be released later this year. I have not planned any bind points inside the mouth. But the Hemalurgic table that we will release will comprise the knowledge of the people in-world at a specific point, and it's entirely possible that new bind points could be discovered.

ElephantEarwax

At what point will they be known? Like, when, in-world?

Brandon Sanderson

When will we know what's smaller than a quark and how gravity interacts with subatomic particles?

ElephantEarwax

No, I mean what time in-world, like what knowledge era, for the chart.

Brandon Sanderson

Oh, okay, I get what you are saying. I was answering the wrong question. What technology era. I believe we are setting the table-- Wax and Wayne era, is what I told Isaac. But it's weird because it's going in the third Mistborn [leatherbound]. But I think our intent is it's what they know by that era. 

ElephantEarwax

So it's what Spook found out?

Brandon Sanderson

Yes, basically it's what Spook found out. But you can't count that quite as canon until it comes out, because Isaac's going to be in charge of setting that date.

How important is Intent to Hemalurgy? If two people who didn't know about Hemalurgy were running and tripped, falling perfectly onto a spike, would Hemalurgy occur? What about if it was a sick psychopath who liked stabbing people with spikes instead of an accident?

Would the planet these events occurred on matter?

Location is not relevant to most of the magics.

Chapter Thirty-Five

How Hemalurgy Works

The epigraphs to this chapter and the ones around it talk about Hemalurgy. I'm feeling that by now, you've figured out what it does. You use a spike on an Allomancer or a Feruchemist, killing them and charging that spike with power. Then you drive that spike into someone else, and they gain that same power. (Though they get a little bit less than the person who died. In some cases, if the spike sits outside of a body for a long time, it can lose a lot of its potency.)

Though this mechanism doesn't add any new powers to the world, I really like the way it works. With Allomancy and Feruchemy, we already have a lot of different magic powers to keep track of. I wanted something from Hemalurgy that wouldn't simply add to the list of abilities, but would instead fit with the feel and the nature of the magic. Something to balance Allomancy, in which a lot of power can be obtained without much direct cost to the Allomancer.

Hence, Hemalurgy. In a way, it has the most potency of all the powers, for with it you can make anyone an Allomancer or a Feruchemist. You can steal single powers from the other two arts, then mix them in a person as you wish. It adds a different element to the world—a way to obtain more power, a way for a common man to become like Vin or Kelsier, but at a terrible price. It works perfectly with who I wanted Ruin to be and what I wanted the conflict of these books to become. What is the cost of power?

Cause and effect, action and reaction.

Questioner

Allomancy requires, you need to be either a Misting or a Mistborn to be able to do that. But Hemalurgy you just need to stab someone through the heart. So what would stop someone on Roshar from using Hemalurgy, because it's not Innate? Do you have to be in proximity to Ruin?

Brandon Sanderson

Intent is a big part of a lot of the magics, including Hemalurgy, meaning that you need to know what you're doing. Or somebody needs to-- There needs to be Intent involved in what's happening to you.

Questioner

So like with Spook when he got spiked, where was the Intent?

Brandon Sanderson

The person who was driving that spike was being influenced by Ruin, and the Intent was there.

Questioner

So unless you knew what you were trying to do with a Hemalurgic spike, you couldn't do Hemalurgy?

Brandon Sanderson

You could not steal attributes no.

Questioner 2

Is it possible to steal Surgebindings.

Brandon Sanderson

It is possible to steal Surgebinding.

Questioner

Is there going to be crossover, like is someone going to have Feruchemical powers and also Surgebinding?

The Mechanism of Hemalurgy

The Blessings and the workings of Hemalurgy gave me some trouble as I designed the second and third books of this series. On one hand, I liked the way Hemalurgy worked by stealing powers from Allomancers or Feruchemists and giving them to other people. However, if I was going to limit myself to sixteen metals and be able to steal both Allomancy and Feruchemy, that meant I needed a mechanism to determine which power got stolen. If, for instance, you drove a pewter spike into a person who was both an Allomancer and a Feruchemist, then how would that spike know which power to suck out and grant to the one who would gain it?

As I was toying with how this would work, I realized that I needed to work the kandra and the koloss into this as well. Only, it was ridiculous to assume that the Lord Ruler would kill Allomancers to make koloss. There weren't enough Allomancers, for one thing—plus it would be foolish to lose the power of an Allomancer to gain an inferior tool in a koloss.

So that meant koloss had to be made out of regular people, not Allomancers or Feruchemists. Suddenly I had another set of abilities that Hemalurgy had to be able to steal—the basic pieces of Preservation inside the souls of all men.

Hence the decision that where the spike was placed in the receiver, and how it was used to kill a person, influenced how the power was shaped. Now a pewter spike could steal any of a number of powers, based on how it was used. And regular people could be used instead of Allomancers—however, when that happened, the receiver was twisted much more than if an Allomantically charged spike or a Feruchemically charged spike was used.

My rationale for this is that if the spike is pulling out the pure power of Preservation—part of the power of all creation—and twisting it, it would change the body of the recipient greatly. Twisting them through use of the twisted power.

Have we seen any evidence of Hemalurgy on Roshar? And, as sort of an addendum, given the end of Oathbringer, was what happened to Jezrien Hemalurgy?

Brandon Sanderson

There are certain cosmere philosophers that would count it. I would divide it as two separate things that are using similar fundamentals... I wouldn't call it myself, but there are people who would disagree with me in-world. Have we seen evidence? I would say no evidence that is easily-- easy to pick out.

Yes, there are people with Hemalurgy who have been to Roshar. I'm pretty sure they've been on-screen.

Khyrindor

You've said that Returned count as Cognitive shadows "stapled" back into their bodies, and that the Heralds are at least similar. Would I be right in assuming that Elantrians could be considered as Cognitive Shadows as well, or am I barking up the wrong tree?

Brandon Sanderson

Elantrians are something different. They don't actually "die" to be created.

Recognize that the term Cognitive Shadow is an in-cosmere theory, which I'm not going to comment on as the creator of the setting. The theory is this:

Investiture seeks sapience. It looks for someone to control it or, in some instances, spontaneously adopts personality.

A mind (Cognitive aspect of a person) can become infused with Investiture. This acts a little like minerals with petrified wood, replacing the mind and personality with investiture.

When the actual person dies, this investiture imprint remains behind. A copy of the soul, but not the actual soul.

Others disagree with this, and think the soul itself persists. Still others reject the theory in its entirety.

linkhyrule5

Huh.

... Kandra are almost literally stapled to their bodies with Hemalurgy - would they count as such, to the in-setting scholars?

Brandon Sanderson

No, they wouldn't. They are beings who have had their souls twisted by Hemalurgy--the soul never left, it's just been messed up. Someone else who has a soul stapled to a body with Hemalurgy would count though.

Questioner

I'm trying to understand the relationship between Hemalurgy and the Shard Ruin. Most of the Invested Arts involve inputs of energy of the Shardic Investiture that corresponds to it. That doesn't seem to be the case for Feruchemy and Hemalurgy. So I'm wondering what the relationship is between the corresponding Shards and those two Metallic Arts.

Brandon Sanderson

There's a whole lot going on here, and I'm not sure how much I can get into right here. But one of the basic concepts I built for the cosmere, way back when, was that a lot of the different magics would be showing up in different systems. And there are certain underpinning fundamental rules. And this is why you'll see Lightweaving working the same way across three different magic systems; I think you've seen it in three different ones so far. Elsecalling's gonna work the same way. Hemalurgy is a thing that is, like, part of the nature of the cosmere, that the Shard simply knew and was able to tell people how to do

So is it of that Shard? Well, yes, because you would have to be following that Shard's Intent in order to use it. But it could be discovered on other planets, as well.

Questioner

And independent of Ruin's presence, really, except for as Ruin affects the cosmere as a whole?

Brandon Sanderson

Yes. Exactly. You are correct.

Barnes and Noble Book Club Q&A ()

Chaos2651

Is there a rationale to how Hemalurgic powers are distributed? I tried to look for a system, but they seem rather randomly distributed. For example, the spike which steals Allomantic powers for a particular quadrant is not always in one particular spot.

Brandon Sanderson

That is correct, it's not always in one particular spot. None of them are. I used as my model on this magic system the concept of acupuncture and pressure points. Placing a Hemalurgic spike is a very delicate and specific art. Imagine there being a different overlay on a human body, like a new network of nerves, representing lines, points, and 'veins' of the soul's spiritual makeup.

What is happening with Hemalurgy, essentially, is that you're driving a spike through a specific point on a person's body and ripping off a piece of their soul. It sticks to the spike on the Spiritual Realm. Then, you place that spike on someone else in a specific place (not exactly the same place, but on the right spiritual pressure point) and 'hot wire' the spirit to give it Hemalurgy or Feruchemy. It's like you're fooling the spiritual DNA, creating a work-around. Or, in some cases, changing the spirit to look like something else, which has the immediate effect of distorting the body and transforming it into a new creature.

Hemalurgy is a very brutal way of making changes like this, though, so it often has monstrous effects. (Like with the koloss.) And in most cases, it leaves a kind of 'hole' in the spirit's natural defenses, which is how Ruin was able to touch the souls of Hemalurgists directly.

Another hemalurgy question: Is it possible to steal more than just spiritual DNA with hemalurgy? If you, say, infused someone with a hundred hemalurgic spikes charged from people who liked chicken, would the spike person enjoy chicken as well?

You can steal quite a lot with Hemalurgy. Anything encoded on a person's soul, really. Not sure if chicken liking counts, though...

If you were to use Hemalurgy on a Surgebinder, would it steal the Surge or the actual spren bond?

Brandon Sanderson

It's going to steal the spren bond, but you've got to remember the spren has power over that bond. So what you're doing is (1) incredibly evil, even more evil, but (2) you may not end up with what you want, because that spren has free will in most cases. You may go through all this trouble and then they may break the bond, and you would be left without it. So you would need something else to force them to be unable to break the bond, which would be even more evil, but it is possible in Hemalurgy.

No, good question. They would just need the metal if you were Hemalurgically getting the ability. Remember, Hemalurgy is basically ripping off a piece of someone else's soul and stapling it to yours.

Brandon Sanderson

When I was designing the Three Metallurgic Arts for these books, I knew that I wanted Hemalurgy to have a built in flaw. A flaw that, as a deconstructionalist might say, was created intentionally and relied upon by the very force hoping it won't exploit it.

It was important to me that Ruin eventually be brought down, in part, because of things he did or flaws in his power. Preservation could simply build into the humans he created an innate goodness, then expect them to do as he hoped that they would. Ruin had to be able to directly corrupt and influence people. He felt himself stronger because he could MAKE them do exactly as he wanted.

The problem is, for his magic to work–for him to exercise control over someone–he had to leave a hole, so to speak, that other people could wiggle through and use. And so the entire "control the koloss" plot sequence in Book Two was intended to set up Hemalurgy, and in a way predict Ruin's fall.

Now, the only problem in all of this (for the heroes, at least) is that when Ruin actually got free, he was so strong that it was all but impossible for anyone else to "get through" the holes that he had left in his Hemalurgists. But it wasn't impossible. In a way, the foreshadowing in this book was meant to lay the seed that Ruin's control of his minions is not absolute. And an individual who wanted to resist him had that potential.

Chapter Thirty-Seven - Part Two

Human Tries to Make a New Koloss

Yes, koloss are people. I assume that many of you guessed this. Then, again, many of you probably didn't. The clues are there, if you care to look—including the fact that small spikes were found in the koloss bodies after the siege of Luthadel. (It's mentioned at the end of book two.)

Unfortunately, the heroes just don't know enough about Hemalurgy to make the connection until this dramatic reveal by Human. There are only three magic systems in this book—all related, all dealing with metal. It's mentioned in book two that koloss, Inquisitors, and—yes, even kandra—are related in some way. All were created by the Lord Ruler during his Ascension.

And all were created from existing material, one might say. There's a little more depth to the kandra, since they're a race that (kind of) breeds true. You'll see as the book progresses. However, all were created through Hemalurgy, and the spikes are very, very important.

Questioner

I was wondering if a Hemalurgic spike would take surges, or if it could take a spren bond? Would it interact at all for that?

Brandon Sanderson

Hemalurgy can interact with every one of the magics. I designed it specifically in writing Mistborn for future use. Because some of the magics are so limited by their planet I wanted one that transcended all of them and Hemalurgy is very important to the entire cosmere. Its invention is a thing of great power and great danger to the entire cosmere.

Yes, but don't take the "of Ruin" and "of Preservation" too strongly, but yes.

Questioner

But, I mean, somebody couldn't just walk along with a metal spike on, say, Nalthis, and stab 'em and now they have the power, could they?

If they knew where to stab them, yes, they could.

Questioner

Anywhere in the cosmere?

Yes.

You can stab someone and get their power?

Brandon Sanderson

Hemalurgy has been built in such a way that it rips off pieces of the soul. If you can rip off the right piece of the soul and attach it to somebody else, it will change your Identity, and it can rewrite anything that's attached to your soul. Identity, Connection, it can rewrite Investiture, all of this stuff it could potentially do.

Brandon Sanderson

No, that's metal, that's—

Well yes, you could make it do something like that. That is totally possible. But the metal— Yeah. Anyway.

Questioner

With the other Shards you kind of have to be near that Shard to get that—there's no Allomancy.

Brandon Sanderson

To get it, yes. To have that part of your soul. But, for instance, Allomancy would work on other planets. The only one that's going to have trouble working on other planets, right now, are the ones on Sel because of the way that the magics are built.

Questioner

We’ve seen several groups throughout the cosmere that have the express purpose of collecting Investiture from the various systems. I have a fear that there is a group that is going to (either now or sometime in the future) go around collecting Investiture specifically through Hemalurgy.

Brandon Sanderson

Which is theoretically possible and horrifying to consider.

Questioner

So my question along those lines was: what happens when you use a Hemalurgic spike on an Aviar?

Brandon Sanderson

You are a very mean person. Basically, an Aviar’s got a mini-bond, so it’s gonna work in a similar way to what would happen if you were trying to do it to a Knight Radiant, which I’ve talked about in the past. Which means it is a less effective way to try to steal something with Hemalurgy, because once you’ve got two individuals involved in it… The Aviar, obviously, isn’t exactly the same. But it’s going to work, but it may not last, I guess is the answer I would give you on that.

Questioner

If that Aviar is already bonded to a person, how does that spiking affect the person they are bonded to?

Brandon Sanderson

That bond will last, but how long? Who knows. Basically, you’re gonna fool the system into thinking you’re the Aviar if you have done that. So the system is going to assume that’s what you are.  They’re gonna see you as the bird if you put the spike into yourself. But, because there are multiple individuals, things like this, and you’ve got the whole thing with the Aviar and their symbiosis, and things like that. It is not gonna work nearly as well as stealing something from, say, a Feruchemist or an Allomancer.

Questioner

*inaudible question relating to Hemalurgy*

Brandon Sanderson

So Hemalurgy... Yes, to an extent. The koloss are an example of this. Koloss are made, but then they can be passed on a little bit. You get koloss *inaudible* koloss. So it doesn't quite work exactly, but some things can be passed on.

Questioner

Do the *inaudible* get passed on?

Brandon Sanderson

Uh... Not necessarily. They're not still pierced by metal.

Questioner

Apparently they use Hemalurgic *inaudible* bloodline to the point where there's Mistborn again?

Brandon Sanderson

This is something that people in-world are wondering.

Questioner

Hemalurgic spikes degrade very quickly, but Feruchemical metals can hold on to their charge forever, apparently. Is that just because Hemalurgy is corruptive?

Brandon Sanderson

Yes, though I may not say "forever."

Questioner

But it's much slower?

Brandon Sanderson

Yeah, way slower.

Yes, it's the nature of Feruchemy and Hemalurgy.

Vasher uses Awakening in a very interesting way, off-stage, to modify the memories of the girl he rescues. Can Hemalurgy do the same thing if used carefully?

Brandon Sanderson

*long pause* No, I don't really think that it can. Nobody has asked that before, but just looking at the way the magics work, I don't think that is something that Hemalurgy is capable of doing.

So in the trilogy, we see that when someone has a Hemalurgic spike implanted in them, they can hear Ruin talking to them, both as a vision and in their head. However, we learn in the Hero of Ages that Ruin cannot hear a person's thoughts no matter how much under Ruin's influence they are.

In Alloy of Law, we see that Wax (and other Pathians) uses an earring to "pray" to Harmony, and we see that Harmony can hear his thoughts and respond.

So I guess this leads to three questions: How does Harmony hear the thoughts of Wax, when it's explicitly pointed put that Ruin cannot?

Are the earrings that the Pathians use Hemalurgically charged, as otherwise they would be of no use to Ruin, and therefore Harmony?

Or did Harmony completely change how that aspect of Hemalugy works?

Brandon Sanderson

How this all works dates back to the original design of the magic system.

I wanted Ruin and Preservation to be complementary opposites, like many things in the Mistborn world. Allomancy, for example, has Pushes and Pulls were are less "negate one another" opposites, but instead two sides to the same proverbial coin.

Ruin is invasive. The power is more "Yell" than "Listen." The philosopher would probably have some interesting things to say about the masculine symbolism of Hemalurgy and its spikes.

Ruin can insert thoughts. That power, however, can't HEAR the reactions. It's about invasion.

Preservation, however, is the opposite. Preservation listens, Preservation protects. (Perhaps to a fault--if there were no Ruin, there would be no change to the world, and life could not exist.) Because of this, Preservation can hear what is inside people's minds. It cannot, however, INSERT thoughts. (This is important to the plot of Hero of Ages.)

Harmony is both, the two complementary opposites combined. And so, he inserts thoughts with Ruin and still uses Hemalurgy. He can also listen.

Yes, Wax's earring is Invested. (Or, in other terms, it's a Hemalurgic spike.)

bettse

Doesn't that imply it was shoved through someone's heart at one point (ala Steel Inquisitor creation process)?

Brandon Sanderson

Yes, the metal would have to have been part of a spike that at one point was used to kill someone and rip off a piece of their soul.

Questioner

As far as Hemalurgy, when you give that-- when it's done to somebody, would that create a new resonance?

Brandon Sanderson

It's possible that it could. Though I'm gonna say, most of the time, no... Lots of things are possible, but I'll give you a "mostly no" on that one.

Questioner

What about savantism? Is that possible with Hemalurgy?

Brandon Sanderson

Yes, it is.

Questioner

Allomancy is of Preservation, correct?

Brandon Sanderson

Yes...

Questioner

What are Feruchemy and Hemalurgy of?

Brandon Sanderson

Hemalurgy is definitely of Ruin.

Questioner

Is it of pure Ruin?

Brandon Sanderson

Yes. That's a very Ruin thing. And Feruchemy is more of a blend. Though… there is more philosophy to that and human construct—like the Allomantic table—than I think I’ve made clear before.

Questioner

Are Hemalurgic spikes fabrials? Is a body that has been spiked a fabrial? Are koloss and kandra also something similar?

Brandon Sanderson

No, actually.

Fabrial means specifically a bit of Investiture that has been trapped by a gemstone and then modified to do something else. Hemalurgy is its own thing--though there is a slight similarity. In most Hemalurgy, Investiture keyed to the Identity of someone (a bit of a soul) is ripped off, and then magically grafted onto someone else's soul. Not the same, though I can see the confusion.

Koloss and kandra are similar, though in this case, the soul is mostly just being distorted by using an Invested spike. In the cosmere, the body will attempt to match the soul, and so a twisted soul (Spiritual aspect of a person) can have profound effects on both mind and body.
