Yeah, it's just using Nale as the example for a general rule. They can do that, but only Nale has ever done that. I doubt it very much. Renarin seems fine with his Corrupted spren. Unrelated to both. The 3rd Bondsmith isn't missing, nobody has bonded with the Nightwatcher yet. It's not like there were always three Bondsmith, it's just that there can be a maximum of 3 Bondsmiths - Melishi was the only Bondsmith during the Fals Desolation. 9 is the number of Odium, just like 10 is the number of Honor. Unmades to Odium together are like the Stormfather to Honor, or like the Nightwatcher to Cultivation. The Sibling was most likely to be the Unmade equivalent of a Bondsmith spren but this plan has failed.

Oh, I like it very much. We rarely speak about the consequences of Helaran and this idea gives it a nice and meaningful conclusion. Disagree. He is a despot who has trouble giving away his almost absolute power. I think this will be a focus for his arc and his next Ideal. No. It just lost his form, but the spren was fine and reformed later. It was said maybe even in the book. But this WoB confirms this: That's the Surge of Adhesion, manipulation of pressure. It's impressive, but still falls within the ability of normal Windrunners. Yes and we know this is significant: They were not controlling them, they were protected by them. Those are some interesting predictions, it was fun reading them.

Could you quote it? I can only think of this one: Which says they are patrons of Orders, not members. This is something spoken in books, even by Nale who said he is the only one to join them - which means the only one who bonded with a spren. Being a patron doesn't require them to be bonded - they had the same power sets because of their Honorblades. OB ch 106: This connection doesn't have to be a literal Connection. It can be just that Heralds are mentally broken, which causes cracks in their spirit webs and Unmades just try to access the minds of people by those cracks (just like Ruin's control is achieved by using cracks in the soul). Thrill is using the same mechanism as emotional Allomancy. But if there is some greater Connection then I don't know. They ripped pieces of Heralds souls, invested them and made Unmade out of them??? This is kind of what Jezrien's words suggest: "They ripped my brain out and made it dance! I watched." This idea is a bit far-fetched in my opinion. HoA WoB:

Three confirmed Ideals - the First Ideal still counts. Two Truths are confirmed. We don't know if "I killed my spren" counts as the 4th Ideal: Well, she was manifested to help her cope with touching her Shardblade, with memories that she killed her parents. She spent the first few chapters trying to escape from the truth that she killed both of her parents, then Adolin came and forced her to confront this - so she hid. But just like Veil who already was with her in her childhood, Radiant was also already there. Radiant is related to some other holes in her memory that still remain after Veil was integrated. OB ch 15: RoW ch 115: Do not say those words! I highly value his PoV because he is the only non-Radiant main character now and his story with Maya is great. She already has a reason to Worldhop, RoW ch 115: Killing Adolin would reduce her entire character arc to ashes and bring her back to the very beginning of WoK. It would nullify 5 books worth of progress.

No, it's not on the balcony, it's on the ground, outside - he fell through his balcony, WoK Prologue: Thaidakar as the Stormfaker? I'm quite sure it's impossible. He lacks abilities to perform such a hijacking, he is unable to even leave Scadrial, and they were talking just a moment ago. It makes no sense for him to be the Stormfaker, I don't see anything he could have achieved by this. Gavilar just discovered the Stormfather was lying to him, he was dying and the Stormfather granted him the last act of mercy, giving him peace by saying it wasn't him - a question Gavilar would have asked himself. It makes sense for the Stormfather to know about it. He's Honor's Cognitive Shadow, remnant of the god, connected to the pieces of Splintered Honor, prepared by Honor and acting as Honor himself. If one were to replace Honor in the Oathpact it would be the Stormfather. Heralds are unable to sense each other's death, no other entity would be Connected enough to sense that. Yes, he seems indifferent about it and that doesn't make much sense. However the Stormfather knew this was inevitable from Honor's visions, so that might explain why he didn't care that much. It's still weird a little WoR I-5: Hoid's goal is to permanently imprison Odium on Roshar. I doubt he would want to fasten the incoming Desolation. He wants to delay Odium as long as possible. I doubt it's him. A Voidspren has no means to know that a Herald died. And why a Shimmer face only? The Stormfather appears as a shimmering to Dalinar as well, he spoke in terror about Gavilar just giving in on Braize instead of stopping Desolations for as long as possible. The shimmering Stormfather has too many moments when he fits with the real Stormfather. This can't be the division. The idea to abandon the Oathpact came from Ishar when the battle was ending, when they all met together and realized all but Taln and possibly Kalak survived. They knew for sure Taln was dead - Jezrien reported this to Kalak with certainty (messengers?), they weren't sure about Kalak. The fact that Kalak didn't know about this means they talked about it together with Ishar before they’d disbanded. Ishar wasn't sure if Kalak survived too then. Ishar can't feel Herald's death. It's really simple. No proof - Dalinar saw the Oathpact, he saw only one line that was still strong (Taln), the rest was equally weak. He didn't see any other line being stronger than the rest. And if in Prelude Kalak, who was still bound to the Oathpact, was unable to feel a Herald dying, then Ishar with mostly broken Connection would be unable as well. Not to mention Ishar back then was still unable to feel that. RoW ch 47:

I think I agree - if they do the same amount of compression cycles. The more times you compress, the more you lose. Tapping 5x loses less investiture than tapping 10x, no matter the outcome percentage. I'm 100% sure they can't do that as for right now, I doubt it would be ever possible. That's one of Feruchemy's limitations, you get what you stored. For that you need a lot of skill, but yes. With this in mind you can use that in Compounding, that's true.

Didn't you originally disagree that you lose the attribute to compression when tapping at a rate greater than stored? Wasn't this the whole point? Because I responded to you with that in mind and that's what I tried to prove to you, and you now agree to it, so I don't know what this discussion is about. You do. We've never seen any Feruchemist tapping less than the rate at which he stored. From the WoB, you compress with increments of your storing rate - you store 50% of an attribute, you can compress to 100%, 150%, 200% etc. You can't store 50% and tap only 10%. On the other hand books often say you double, triple or quadruple your attribute - still it depends on your storing rate. That's why from the tapping perspective, if you have 2 metalminds, one with 5% for 20 min, other with 20% with 5 min and you want to tap 20%, or let's say 40%, then in both cases it's far better to tap the second one, already filled with 20%, otherwise you will lose most of your attribute to facilitate compression. So from the tapping perspective, you would get more investiture from the metalmind that already has 20%, than from the one with 5%. Respectfully disagree. In Feruchemy you always deal with percentages. When you compound, you take the original rate of storage in metalminds and multiply it by the compounding rate, getting greater rate and more attributes. You get more investiture, in the form of stronger and vaster attribute. You don't even have to store the compound attribute, you can use it directly and I believe it would be delivered at a fixed rate - it's possible Paalm was doing just that. I'm expressing myself very poorly here, I hope you get what I want to say. Disagree again. While some mechanics were not clearly defined back then, diminishing returns were well developed back then, being the backbone of Feruchemy. My point was to just poove that compression returns cause loss of attribute to compression. Yes, of course. Numbers are just an example to make it easier to understand. It's just to show that you lose attributes. My point is to show that from the tapping perspective, if you want to have an attribute for longer, you use a metalmind that is stored at a higher rate because you lose less to compression than a metalmind that is stored at a lower rate, because you need to compress the second one more than the first one. Again, the example of "one with 5% for 20 min, other with 20% with 5 min." So if you use 40% for the longest, you use the metalmind with 20% and it will give you more investiture then the first one, because less attribute was lost to compression, even if both started with essentially the same amount of attribute.

This is just an imperfect analogy. You need to provide energy to make something more concentrated. To compress stored attributes, you need to provide some energy to compress it and because Feruchemy is end-neutral, you can use only what's in metalminds. So the process is using some of the stored attributes as energy to compress the rest of the attributes to a higher percentage - that reduces the time by more than half. The more compression cycles you want to have, the more investiture is used as the energy to facilitate that compression, the more attributes you lose, the less time you get from it. If you have two metalminds, one has 5% for 20 min of attribute, the other has 20% for 5 min, they might essentially have the same amount of investiture (if we assume they were both stored by the same person). But if you want to use the first one with 5%/20 min and tap it with diminishing returns to get 20% of attribute from it, you won't be able to use it for 5 minutes. You need to compress it 3x - first time to get to 10%, second time to 15%, last to 20%. This causes some of investiture to be used to compress the rest. After the first cycle you will have less than 10 minutes, let's say 8, another step will make it less than 4, let's say 3, and the last will make it less than 1.5 minutes, let's say 1 minute. If you now compare it with the second metalmind, you essentially lost most of the attribute just to compress the remaining one, you have only 20% for only 1 minute, instead of 20% for 5 minutes. I used this WoB for this example. Each increment cuts time by more than half. The point is by compressing the attributes you will lose more and it won't be equal if you were to just store at greater rate for less time.

Radiants require Oaths and Ideals. Spren at first were just mimicking Honorblades - they gave people Surges and Shardblades. There is no issue. Radiants were bound by Ideals, proto-Surgebinders weren't and they could have still had their blades without Oaths. Or shortly before it, but yes. But there were dozens of Desolations. Possible, but this could have happened even earlier. We don't really know. It would be nice if we know in what Epoch did Nohadon live. Spren could have started mimicking Honorblades during, or shortly after the First Fused Desolation. But I suspect it happened much later, during the second, third or maybe fourth Desolation (it was said that Fused didn't always know how to use Surges, Spren might have started to mimic Honorblades as a direct response to Fused using Surges).

Rayse didn't want Ruin, he specifically asked for Odium. But I think it's likely that Ati was chosen (and he decided to pick up Ruin) because they knew he would be good at controlling Ruin. The Second Letter: No, they both agreed to create humans, that was their deal - they agreed to create sentient humans and Ruin was allowed to destroy them. By the time they had made that bargain they were already overwhelmed by their Shard's intnets - Ati was looking for satisfaction from destruction, Leras wanted to preserve everything. HoA ch 53&54 epigraphs: Rashek had never opened Ruin's prison. He took up the power and used it and that wasn't opening it. Giving the power up without using it was opening the prison. The power had to be used. HoA ch 46 epigraphs:

We don't know we, but we know all sapient spren are post Honor&Cultivation and that Adonalsium didn't want Spren to have access to Surges. WoBs:

One thing is that Honorblade doesn't require Oaths and the Nahel Bond to work. Next, Heralds had access to Honor's power directly from Honor, without any need for Stormlight and that's something Honorblade allowed them to do, or at least were a part of it. That's definitely one of the things the Stormfather meant. Because they both use dangerous amounts of Stormlight (they are less efficient than Radiant bond) and they can allow to draw power directly from Honor, I wouldn't be surprised if they could quickly make its user into a Savant (just like Soulcasters do). The amount of power flowing through your soul would be pressing hard on it. And that would make you even more powerful. We don't know how Honorblades connect to the Oathpact, or even what came first, we do know that one of the main reasons Heralds abandoned their blades was philosophical in nature. Both Nale and Ishar reclaimed their blades so it's not like they have to leave them behind.

Doubtful. Only Nale has joined his Radiant Order, only he has bonded with a spren - and that spren is fine, even if they were present with him on Braize a few times. The Unmades were likely made out of some Spren present on Roshar - just like Rabiniel tried to do with the Sibling. However it's also possible that those Splinters weren't originally from Roshar. We don't really know. But there is some connection between Unmades and Heralds - Heralds can sense their presence and Unmades possibly influence their madness in some way. Jezrien was talking about this to Dalinar in OB ch 88: WoB you were referring to: Heralds madness is because they have lived for thousands of years while being constantly tortured - a human soul isn't made for this. Fused are affected in the same way, you see this with many of them, like Raboniel's daughter.

I doubt this. True, the timeline of Ishar becoming Tezim is suspicious, but the way Ishar reacted to the Stormfather's bond with Dalinar indicates that he had no interactions with him (or someone pretending to be him). Ishar was surprised that the Stormfather is bonded, but his conclusion was "he's corrupted, I need to steal that bond," which doesn't fit if he was interacting with someone imitating the Stormfather. The Stormfather talking himself to Ishar is out of the question - he would never allow any of his beloved Honorspren to be hurt like this. His reaction to Spren bodies found on site was too real and too emotional to be a lie. The Stormfather didn't know that, he was shocked that Spren can just die like humans. RoW ch 111: It's not just in his chambers, he appeared as shimmering at the very end, outside the palace, when Gavilar was dying. He didn't talk about the fabrial, he just thought about it, crediting Navani for the idea that was useful in his study - and I think that was the goal of this, to show how Gavilar was able to get Voidlight and anti-Voidlight. Those thoughts appeared after the Stormfather appeared. The opposition part is weird, but the "so close and so far" is easily explainable - it was the first time Gavilar spoke words with Intent. All other attempts were just wild guesses with no Intent behind them. The Stormfather said it himself just a moment later: Could the flower be the Ghostblood's symbol? It also looks like Aesudan is in on it and whisks Navani away before she can get a close look at the box. The fabrial is also brought up in the OB prologue. Thoughts? Oh, that's interesting. Yeah, that could be Mare's flower, he could be Ghostblood. And that would fit - Thaidakar just spoke with Gavilar, he said that they gave him very valuable information - he could be one of Ghostblood. However, Gavilar said that because of Navani's study he had found a way to use gemstones and then he started to take interest in Artifabirans. It's more likely that Axindweth was of Ghostbloods instead. Moreover Ghostbloods avoid using their symbol so publicly. I doubt then that it's the Ghostbloods symbol, but it's still quite possible.

Why bother with wormholes when she is making perpendicularities all around Cosmere, using CR to move her troops and agents, or using spaceless SR to manifest her Avatars? Why bother with a wormhole instead of making some kind of Elsecalling and basically teleport her agents wherever she wants?

It's kind of possible, if you Awaken those metalminds, or rather it's possible that those memories and identity will have some influence over the Awakened construct and it will be able to use them. With access to a Coppermind containing all memories of that person, an AI like that will be able to at least simulate that person. No. He didn't care to make a replacement for himself, nor did he want somebody to have access to powers like he had and have his memories, which would reveal his secret. Have you read The Secret History? An AI would most likely have a soul. Nightblood is a robot-spren already.

Highly disagree. Spren ARE changeable. We see this all the time with spren like Syl, Pattern or Wyndle. They grow. But even unbounded spren are still changeable. Examples? The Stromfather - he is changing his mind all the time. He sent visions to Dalinar, but when he failed to stop Parshendi from summoning the Everstorm, he sent his Highstorm to kill them all and hide his own failure. He was trying to stop Syl from returning to Kal, but he accepted his Words letting her go. He refused to bond with Dalinar, but a second later accepted his words. Or in OB he refused Kaladin's request to save people from his Highstorm, but later he felt apologetic and guided Kaladin back to Urithiru. He didn't want to tell Dalinar who Ishar is, he hid from Dalinar that he can speak other languages revealing this only when he was pressed by Dalinar. In RoW he kept telling Dalinar not to push him, but when Dalinar was riding the storm and pushed against the storm, the Stormfather was curious, not angry. In the end he even showed mercy to Eshonai, admitting he should have done more to help her. Even some Honorspren believe that the Stormfather has changed lately. And there are also many other examples of Stormfather changing his mind almost immediately when pressed by Dalinar. It's there, in WoK, WoR, OB and RoW. All there, hidden in plain sight. Another example of a changeable Spren is Notum - going from Syl's imprisonment, through threatening Kaladin with death, to letting them go and ending up standing up for his honor during Adolin's trial. Phendorana - she argued with Syl against bonding, yet when Syl succeeded and the True Desolation started, she was one of the first to guide other Honorspren to the Bridge Four and one of the first to bond with another person - Teft. She changed. OB ch 37: Other Honorspren - there is a division between them, as seen in RoW. Many are angrily against bonding with humans, others are willing to bond, some even want to switch sides and join Odium. Honorspren in general are highly changeable. The most obvious example is the Sibling - they swore they wouldn't bond with people again, they refused to bond with Navani, deeming her unworthy, they refused to trust people - and in the end yet they accepted Navani's Words. RoW ch 113: And lastly the Nightwatcher. She was made by Cultivation specifically to grow and develop on her own. To change. Spren are sentient, they have free will - they can change, they can choose. It's not against their nature, it's part of their nature. Some are just refusing to accept it, but all spren can change. I fully agree, that's why I don't believe what Gavilar claims about what the Stormfather had said to him off pages. Gavilar is too proud, too self-centered, too flawed and too quick to make assumptions to be trusted. Nobody tries to argue that Gavilar's Stormfather isn't weird - we all see that. However in my opinion the evidence for that entity being the Stormfather are far more convincing than the evidence pointing towards Ishar or some other less likely Stormfaker. The Stormfather in all previous books has already proven himself to be mentally broken and unstable, able to change his mind at a moment's notice, willing to hide certain information from Dalinar unless pressed to reveal them. Being angry when someone demands something from him, yet sometimes still doing what he was asked for. This is exactly how Gavilar's Stormfather behaves - in the very same way. The Stormfather showed that he can be merciless and even malicious - willing to kill Kaladin in WoK&WoR, lying to him about Syl in WoR (Kaladin "killed" her. but the Stormfather kept her away from him - she wasn't fully dead because Kaladin didn't fully break his Oaths like Shallan did - this was a lie), sending his Highstorm to kill everyone during the Battle of Narrak. Not to mention all those times he killed people in Highstorms - where was his honor at those times? The Stormfather is not a pure and good entity with clean hands, he calls himself a storm and storms are treacherous, dangerous, changeable and unpredictable - just like Gavialr's Stormfather. Moreover we were shown that the visions Gavilar was seeing are the same as Daliars saw - this means it has to be the Stormfather showing them to him. This WoB confirms that: https://wob.coppermind.net/events/122/#e3316 The entire conversation between Gavilar and the Stormfather is consistent. By that I mean that I see no weird sentences where a Stormfaker could be speaking. This means that the entirety of conversation has to be spoken by one entity only - and everything is pointing to the real Stormfather. He could take Gavilar out of visions, he saw potential in Dalinar, he responded in the same way to Gavilar's demand as to Dalinar's demand in OB ch 38, he felt Herald's death and many others. I see no words being spoken that were really standing out or were inconsistent with previously ongoing conversation. There are 3 main problems, which convinced me that Ishar can't be the Stormfaker (and he was the best candidate) thus it has to be the real Stormfather who can lie: Ishar should be insane, just like every other Herald. Ishar was shown to be insane the moment he first appeared in OB (the letter he sent to Dalinar), but even decades earlier, he advocated for killing all new Radiants, which doesn't make much sense considering Radiants existed for 2500 years post Aharietiam and they weren't any problem back then. The entity speaking to Gavilar is far too stable to be Ishar. Ishar CAN'T feel another Herald being killed and returning to Braize - this was shown to us in WoK Prelude. There is no question about this, this is still a dealbreaker for me. Ishar has no Honorblade during Gavilar's assassination (he reclaimed it after OB) and is highly unlikely to still have his Ashynite powers. It's a disservice to say that one has to discard all previous books to argue for the Stormfather, that one isn't searching for the truth and is just cremposting. The entire point of theorycrafting is to have a discussion, to argue for and against a theory. I believe we all are mature enough to agree to disagree and just have fun talking to each other about interesting ideas. We all exchange ideas and discuss our point of view in good faith. We both are using all previous SA books to show that it is the Stormfather/Stormfaker - I'm not discarding SA1-4 in my believes, my beliefs are based on those books, because there are multiple instances where the Stormfather was shown to be not that good of a guy, someone more similar to Gavilar's Stormfather than to some holy entity with no flaws. That's why I think it's the real Stormfather who was talking to Gavilar, he is not that different from the Stormfather known to us from previous books when you look deeper into it.

It's not heat that is transferred, it's investiture, but because there is a planet in between the star and the core of Canticle, it provides a resistance, heating Canticle's surface as a result. Investiture is energy. And I've got an example of two inanimate objects transferring heat - the 2nd Law of Thermodynamics. But this doesn't apply to Canticle's core, it's too invested, it's in a higher energy state. True, I forgot about this part, like when the Cinder King was drawing investiture from people. Intent is a part of every single Invested Art in Cosmere. Just because people need intent, doesn't mean the planet that was somewhat created needs it as well. Sure, but not every machine needs to be Awakened. You don't need to put sentience everywhere. The planet doesn't do much for now, it just draws some energy in and stores it. It's no more complicated than a giant battery. Not a lot of thinking is needed to achieve that. Your line of reasoning is good and valid, however there is no way to prove or disprove it for now. We know nothing about this structure so everything is possible.

No Windrunner was sent with them to Lasting Integrity. The Oathpact won't achieve that. The Oathpact only made them more insane. Their insanity is caused by how long they have lived for and by centuries of torture they've withstood. The Oathpact won't fix them - Taln is still bound to the Oathpact and now he is the most broken of them all. My prediction is simple - the duel won't happen, Taravangian will outsmart Dalinar and force him to break the terms of the Contest. Szeth and Kaladin will bond a little, Kaladin will help with Szeth's mental health, but they will ultimately fail to get Ishar's help. Shallan and Adolin will go after BAM instead of returning to Urithiru.

Why? Dalinar has his duel, he has his peace no matter the outcome of the duel, there is no need for Oathpact to be remade. Moreover the Oathpact won't work anymore because Fused don't return to Braize, they are reborn in the Everstorm bypassing the Oathpact completely. The idea of restoring the Oathpact is useless with the Contest of Champions in 10 days, it was useless even before that. The Oathpact was already proven to be unreliable and only a temporary solution - it can't stop Desolations, it can only delay them for some time. And that's all without mentioning the horrific cost that Heralds have to pay for it - endless torture breaking their souls and minds. The Oathpact is a dead end.

That's not how Allomantic electrum works - it just shows you YOUR future, while Atium shows you the future of others. Anytime you can see the future, you can react to it, thus you can change the future and react to it changing it again and again and again - this means someone with Atium looking at you will see all those different shadows showing them all different paths you can take. That's what A-electrum does, it just allows you to see the future and that alone disrupts the future sight of others. You look into the future by using Fortune and looking into the Spiritual Realm - that's what both Atium (in its pure and alloyed version) and Electrum does. However, Allomantic gold shows you your past (or alternative present), and it likely works via the same mechanism - by drawing Fortune and looking into the Spiritual Realm. That's why I think silver is unrelated to what's happening with electrum, because other metals without it can do more or less the same thing - peer into the Spiritual Realm. Feruchemists tapping Fortune from chromium would also counter A-Atium by splitting their shadows - this is not unique to electrum, it's just a general rule of future sight. HoA ch 3: While silver is Allomantically inert, it can still be steelpushed despite its disruptive properties. I highly doubt you can alloy silver with any of 16 base metals, it doesn't really make sense, silver is not a god metal like Atium is (which can be alloyed with all 16 base metals and produce different effects). If that would work in this way it would mean that electrum is NOT a real pair for gold and there exists another metal that should be paired for gold - this was already disproven because Sazed gave Scadians tables for Metallic Arts with metals unknown to them and they contain electrum as one of the base 16 metals. I'm sure Brandon would not want to make another blender like he did with Atium retcon, and hid from us that electrum doesn't belong where it do.

Since this is the case, spilling blood in a Coppercloud and later leaving the area should be fine. The same goes for fire; lighting the fire is what causes Shades to become enraged, and there are even people who sell previously lit flames, if I recall correctly. Then maybe it would be safer.

Well, not really. Shades move in random directions, they would still pass near you without sensing you are there. Spilling blood in the Forest would be fine as long as it happened inside the Coppercloud, but once you start moving away from the crime scene they would sense even the tiniest drop of blood on grass and every Shade around you would get enraged, racing to the spot and then just running around the area in fury - that would be very dangerous to you, they may just randomly pass through you in their rage, not knowing that you are there. If you don't respect the Forests of Hell, it will kill you - that's the number one rule. Just follow the Simple Rules.

Time to dig up some dirt, huh? It's a bit embarrassing. It was years ago, probably shortly after WoR release. I think I read every main Cosmere book by that point, starting with the Mistborn series, Elantris, Wabreaker and ending with SA. I just finished reading WoR and I DIDN'T REALIZE THAT NIGHTBLOOD WAS THERE... yeah, I was dumb. I read everything, I read Warbreaker and it still didn’t get to me that it's all connected. The worst thing was that I recognized that the sword looks and talks just like Nightblood, but I still ignored this thinking it was just some cool easter egg or something weird like that. Instead I was "theorizing" Nightblood was Odium’s evil version of Shardblades - it talks like a spren, it looks like a Shardblade, it leaks blackness like you would expect it from something evil and it even talks about destruction and evil - it fits! It told the exact same line Nigthblood said in Warbreaker almost word to word? Naaaah, that's just an easter egg, nothing else. Could you imagine such different worlds being connected in the same universe?? Impossible! A few weeks had passed and I was still living with the ending of WoR. So I reread some fragments of the finale, including Szeth's resurrection. And I missed it again... But this time I was really intrigued by that sword and I thought that there must be some fan wiki about Sanderson, which might contain more information. That's how I found the Coppermind (I think) and I started reading about Szeth. You can imagine my utter shock, when I read Nightblood's name on the Szeth's page. A whole new world just opened in front of my very eyes. I kept reading, being shocked by Vasher, Hoid, Felt, Shards, Cosmere and everything. I read the Coppermind for a whole week and then I had to reread everything, while looking for all those things I'd missed earlier. It was life changing. For my excuse, I had a tendency to lifelessly read books at night till the sun rises. Or I was/am just dumb.

They aren't kinetic investiture, only innate, you won't hear them with A-Bronze. Only maybe when they attacked someone causing withering, that might be a slight kinetic investiture happening. Not really useful. Life Sense would pick them up 100%. A-copper would probably hide you from them. It can hide you from Life Sense. It would even hide everyone and everything in the Copperclouded area.
