This shall be the almighty list of reverse compounding for all books thus far. Feel free to add on to anything I missed. for those of you unaware, reverse-compounding is like a weaker form of full on compounding. Compounding is a magical hack that squeezes an abnormal amount of feruchemy from a metalmind when it is burned. Reverse compounding is a simple breaking of the end-neutrality of feruchemy by using some sort of outside force to increase a storable ability. This basically allows you to do a few cool things, most importantly of which is the ability to become a feruchemical savant. Reverse compounding is most easily done with a combination of allomancy and feruchemy, so we’ll start there. My list will be going down each feruchemantic ability and seeing what other forms of allomancy/feruchemy can be reverse compounded in the metalmind. This will not be covering how other magic systems affect the mix, which will likely be a separate post. I will also note that something like storing weight while tapping strength does not count as reverse compounding, as that extra weight still comes from you. While it sure is nice, and enables extra versatility within metalminds, it ain’t reverse compounding. I also will not be counting compounding for this post, as that’s fairly self-explanatory. with all that out of the way, let’s get started Iron: Iron stores weight, but doesn’t do much else. As we have seen in the books, it has been quite versatile, but it doesn’t do much reverse-compounding wise. Steel: now steel’s more interesting. You can reverse compound pewter’s extra speed, which can end up being quite useful without inhibiting pewter much. You could also maybe reverse compound F-iron, but it seems unlikely. Bendalloy could maybe be used to reverse compound, but it seems extra unlikely, as bendalloy does diddly squat to your body’s capabilities. Tin: tin is the king of reverse compounding, easily beating any other metal. With tin you can store any extra senses created by metals, including steel/iron sense, bronze sense, as well as atium, electrum, and gold shadows. Additionally, it can store extra balance gained from A-pewter and F-steel. I would argue it can also store the G-force resistance from F-steel as well. Of course, it can also reverse compound senses gained from A-tin. For those keeping track, that means that F-tin can store every physical allomantic ability, as well as 4 others. That’s 8 of the 17 twinborn combinations that can reverse compound! And that’s not including the feruchemical reverse compounding. The main downside is that each of these effects that are stored are quite important to the functioning of the other ability, so you can’t do much with the other metal while you are reverse compounding it. Pewter: pewter stores physical muscle mass. Unfortunately, this means it is unable to even reverse compound with A-pewter, which doesn’t affect muscle mass at all. A useful feruchemantic metal, but not for our sake. Zinc: zinc is actually quite interesting. Atium has shows that it increases mental speed, as does F-steel. You could argue that you could store the additional mental speed from a bronzemind, but sadly that would not count as reverse compounding. Brass: brass stores warmth. I had thought before TLM that brass did not have anything it could reverse compound, but due to Wax subconsciously burning pewter to stay warm in the water, we know know that A-pewter can be reverse compounded! This is actually really convenient for a twinborn, as the extra warmth granted from pewter is almost never valuable, enabling the user to reverse compound whenever pewter is burned. Copper: copper stores memories. While useful, it has no reverse compounding applications that I can see. Bronze: bronze stores wakefulness. Pewter assists with wakefulness, if I recall correctly, so that could likely be reverse compounded. Past that, while there is uses for assisting with F-gold or F-electrum, neither would really count for reverse compounding. Chromium: Chromium stores fortune, which is a finicky thing in the Cosmere. Atium gives some sort of fortune, yet I have no clue how that would exactly work. Would it spawn atium shadows? Who knows. So there are reverse compounding capabilities, but they are limited and weird. Nicrosil: Nicrosil stores investiture, specifically innate investiture, which is your ability to use a certain ability. While it is fundamental for the process of making unsealed metalminds, it does not have any reverse compounding uses. Aluminum: Aluminum stores identity, which is weird, but not helpful here. Duralumin: Duralumin stores connection, which can be very useful for a worldhopper, it does nothing here. Cadmium: Cadmium stores breath. F-gold can help squeeze some extra breath out of you when storing, but doesn’t reverse compound. I think it’s fair to say pewter can help here, as pewter allows you to survive with less air. Bendalloy: Bendalloy stores energy, specifically caloric intake. So while you would think pewter, tin, F-steel, or F-bronze would allow reverse compounding, I don’t think it does. You could maybe do something with F-gold, but it wouldn’t really be reverse compounding. Gold: gold stores health. I think it’s safe to say that you could reverse compound with pewter. Interestingly enough, I think there’s some interesting shenanigans you can do with F-aluminum and identity, as gold acts based off of your spiritual identity. Wouldn’t help for reverse compounding, but an interesting note. Electrum: electrum stores determination. You sadly cannot riot yourself to make you more determined, but you could get other people to do that for you, allowing you to reverse compound. Don’t know how useful it would be, but a cool thought. Atium: atium sort of stores age. While I think there’s some weird applications with temporal allomancy and speed/slowness bubbles, I’m not sure it would actually reverse compound. An interesting question though. Alright, I think that’s all of them. For those keeping track, pewter is the best allomantic metal at reverse compounding, reverse compounding with 7 of the 17 feruchemantic metals. Tin is the undisputed best at reverse compounding on the feruchemantic side, with a whopping 8 out of 17 allomantic metals enabling reverse compounding. 8 of the 17 feruchemantic metals can reverse compounded without actual compounding, and 9 of the 17 allomantic metals can help reverse compound. If you have more reverse compounding instances, please let me know. It’s really cool to see, and I hope we see some interesting applications in-world.

Prelude: The Sign of Fire As far as canalside inns went, the Sign of Fire was among the oldest, and the most reputable. The foundation stones had been laid, or so the legends went, in the days of the Deepness, the deep dark days before the Lord Ruler himself had slain the evil and ascended to divinity. Prelans and nobles alike tarried at the Sign of Fire, partaking of the house fare and the wine before their journey led them ever onwards, down the winding waterways towards Tathingdwen proper. Everywhere you looked, Kais said, was water, taking you where the proper flow of things were, whether it was to Tathingdwen, or the water eagerly seeking out the Channerel, and from the Channerel to Luthadel, the beating heart of the Final Empire. (Kais wasn’t much of a poet. But the house wine at the Sign of Fire did that to a man.) The water took you past majestic Torinost, where on a quiet day, the ash didn’t fall, and you could almost believe you lived in one of the days of legend, with skies a crisp, pale grey, and the air fresh and clear. Stories, mostly. And the follies of bards, some of whom wore bright copper bracelets that gleamed as they played the lute and the harp. Count Olaf, the newly-minted head of House Ffnord, set down his wine glass. Anticipation warred with caution; caution won out. He had not been acclaimed as lord of House Ffnord by utter recklessness. Yet, even accepting the invitation had been some form of risk. The promise of House Ffnord entering into a business contract with House Jerzy had been subtle, but it was the sort of promise that you had to respond to, because of the sheer opportunity it offered. Could House Ffnord afford to pass up this opportunity? And then there was the caution there: why meet in the Terris Dominance? House Jerzy was a Western House, famous for its fine wines, answering to the Herons of Tremredare. What business did any Jerzy—or their representative—have, meeting at an admittedly celebrated inn with admittedly fine wine in a Dominance so far from their own? So far, Kais had seemed painfully exacting. He’d wanted to know about the funds House Ffnord was prepared to offer, the state of House Ffnord’s previous ventures, figures, accounts, and schedules. A minor insult, really, that the head of House Ffnord had been met by a glorified secretary, but Olaf smiled tightly and swallowed it. A newly-minted House Lord could afford only so much assertiveness. And the letter had the secret marks, etched into the edge of the paper, indicating authenticity and urgency. Which meant that the Synod, too, was keeping a close eye on things. The thought brought him back to his wine glass. It was good wine, and Olaf felt his mood ease a little. Tathingdwen was a city of secrets, and the Synod was the best-kept secret of all. It was very much like the Synod to proceed with this level of skulduggery. Wheels within wheels. Generation after generation of Keepers, preserving the collective knowledge of the world within their copperminds, against some distant future where it might be needed. Always hoarding, in some desperate, blind faith. Risk endangered not just one member of the Synod, but the painstakingly-gathered treasure trove of human knowledge. “I presume,” Kais said, “That we can trust to your discretion.” He sketched it; slowly, with his index finger, the sign for authenticity again. And there it was, and Olaf wondered if it had been just that: some lie to wrangle him north, to the Terris Dominance, when really, any true representative of House Jerzy should have been satisfied with a meeting in the West. He made the recognition sign, slowly, deliberately, aggravatedly. “Do you represent House Jerzy, then?” Olaf wanted to know. He did not like the feeling of having been used. He did not much like being led on a merry chase under false pretences, either. Kais nodded. “This much is true. House Jerzy has been looking for new distributors with access to more lucrative markets. It was suggested that House Ffnord has those capabilities. The question of course is whether we have common interests, and the contract is suitable.” “I believe we’ve spent the past hours establishing that House Ffnord has the connections that House Jerzy seeks,” Olaf said, tightly. Two layers at once. Always deception, always another secret. “Have you,” Kais said, a seeming non-sequitur, “Heard about that business in Frebarind? A nasty affair, that.” “No,” Olaf said, tersely. “I can’t say I have.” “I think you’ll find it—interesting,” Kais said. The fire crackled with warmth and light, but Hazen still felt cold. He unfolded the letter again, and read it, but the words never changed. They know, he read. They’re coming for you. Get out as fast as you can. It was tempting to dismiss it. The Synod was too well-hidden; generation after generation holding fast to the secrecy that was their chief tool of survival in the Lord Ruler’s harsh world. But there were the deaths. Ias had drowned; a simple boating accident, they said. Canal boats were well-known to tip over, if the boatman wasn’t careful, and the boatman had been drunk. It didn’t matter that Ias knew how to swim. He’d gone under the boat, and hadn’t been able to get to the surface. Hadn’t stored pewter either, though Hazen wasn’t certain if tapping pewter would have helped. Perhaps it would only have meant that he would have drowned faster. Ancestors’ mercy, Hazen thought. A terrible way to die, drowning. And Ias had always that bright smile, the one that lit up an entire keep with its warmth. The boatman responsible was dead soon after: an attempted mugging gone bad fast. They’d found the murderer, and had strung him up without mercy. But it didn’t matter. The boatman was slain, and Ias was gone; another source of brightness faded from the world. Perhaps he had simply burned too brightly. But then there was Pashan, who had been run over by a wagon, and seriously injured. The wagon-driver had been distraught, and had sworn again and again that something had spooked the horse. Hazen did not think the man had it in him to lie, and yet the horse, a solid raw-boned draft-horse that was getting on in years, was placid, and Hazen would sooner swear that he was Mistborn than believe that the horse had spooked. Pashan had died in her sleep, days after. Radur had been knifed in an alley while on the way home. There were only so many unexplained deaths you could accept, before you had to start to ask questions. Before you had to wonder if there was something more sinister at work there. The Synod had sent them all to Frebarind. Hazen had been proud to accept the charge of leading the small branch of the Synod there. Frebarind was a bustling settlement, and the Steward of Tathingdwen was sparing no expense in investing in it. With the flow of funds came nobles and obligators, and various opportunities for the Synod to establish a presence in Frebarind and to listen in on the secrets and whispers of power. Not everyone had liked this move. The traditionalists had claimed this was too ambitious; that the Synod’s place was in the shadows, that this stepped too close to attempting to place a hand on the rowing pole. Their place was not to steer the boat, but to keep to the shadows beneath the water. The pragmatists had claimed that this was their chance to establish a new presence, and every available opportunity to increase the Synod’s resilience should be taken; they could not always rely on secrecy to save them from the Lord Ruler. The historians had flatly claimed this was a distraction from their sole task to preserve knowledge and ignored everyone. Did this sort of disagreement drive Keeper to kill Keeper? Hazen didn’t know. The thought was a distressing one. And now, days later, a letter had come to him, borne swiftly by water, and by the secret channels and ways that the Synod knew of, and bearing the etched markings for authenticity and urgency and secrecy, and a dire warning. Hazen bowed his head. He was the head of the Synod-in-Frebarind. Leaving was deserting his post, abandoning those under his care. And yet the letter had come, but it bore only a warning; no strict orders to leave. Decision made as swiftly as impulse; Hazen balled the letter up and tossed it into the crackling flames. “No,” he said aloud. He had a duty, and he was charged with the protection and the safeguarding of the Synod-in-Frebarind. His place was here. Even if staying here killed him. The watchman cried the hour. All was well. Few were brave enough to dare the mists, although the nobles and the Allomancers among their number might very well claim the mists as their own. In a small, unremarkable house in Frebarind, Hazen lay still on the ground, blood pooling onto the carpet. His arms were badly burned. The fire roared; the Keeper had stuffed it full of important documents, preferring destruction to having those documents used against the Synod. A desperate move, perhaps. Or a dying man’s defiance. It did not matter. Flames spread across the wood-paneled study, and across the house, and in an hour’s time, the house itself went up in a shout of fire. “Hazen,” Kais said, “Was a fool.” He looked at his wine glass, but his gaze seemed distant, recalling. “The Synod’s eyes and ears had received word that the Synod-in-Frebarind had been compromised, but we were not certain what the nature of the compromise was. I sent warning to Hazen. He chose to ignore it.” An entire branch of the Synod compromised, Olaf thought. It sounded disturbingly familiar, as though it was the same story, the same pattern, playing itself out again and again. He thought of that business in Luthadel, and the obligators. “And then he was dead soon after, and the Synod-in-Frebarind panicked. As though any reasonable person would not have been concerned after the first death!” He shook his head. “The Synod debated, of course. As always. The traditionalists screamed that this was the end, that everyone had to go back into hiding and the Synod-in-Frebarind had to be severed—” he made a sharp, cutting gesture with his free hand, “—forgotten, abandoned as lost. The historians didn’t care, but didn’t like the idea of abandoning our own. The pragmatists pointed out that cutting off the Frebarind branch meant we had no way of assessing the extent of the damage, or reasonably figuring out how much the Steel Inquisition knew, or how much trouble we were in.” The Steel Inquisition. Words to chill the heart, even now. And as the newly-minted House Lord of House Ffnord, Olaf was sternly resolved to stay on the right side of the Steel Ministry. Even the lord of a Great House gave way when the Steel Inquisition got involved. “Surely the most reasonable resolution was to assess the situation,” he temporised. “The Synod in Tathingdwen, no matter how well-informed, was too removed from the situation in Frebarind to make the necessary decisions.” Kais nodded approvingly. “That was the conclusion they reached eventually, when wiser, cooler heads prevailed. I was in Tathingdwen then, because Lord Jerzy was attempting to negotiate cultivar access with another House, and could be easily dispatched to Frebarind.” “How bad was it?” Olaf asked, curious in spite of himself. He had not heard of the Frebarind affair; he had been somewhat removed from Synod politics since his accession to the House Lord’s seat, and yet there had been something in the messages from the Synod of late. Something that suggested weight, foreboding. “The Synod-in-Frebarind was thoroughly infested with Spiked infiltrators,” Kais said, with distaste. “I don’t know what Hazen thought he was doing, but it needed to be purged, to the root...” Welcome to Long Game 86: A Stricken Match! The Terris Synod in the quiet town of Frebarind is threatened by Spiked servants of the Lord Ruler in their quest for the knowledge sought by the Keepers. Fail to root them out in this formerly sleepy town, and the last bastion of Feruchemy will be left vulnerable to his minions. This game is a rerun of LG48, but features minor edits to a few of the Ferring roles, and a slight change to the action system as well. Otherwise, it should function fairly similarly. You may access the rules here. Clarifications asked from LG48 are already in the doc, so please check there first to see if your question has already been answered. Also, please note for story and character purposes that this is a prequel, as Olaf has not reduced Tathingdwen to ashes quite yet. He's getting there, though. My co-GM for this game will be the wonderful @Kasimir. You have him to thank for the intro writeup, as well as all the writeups going forward. He will also be doing his best to fill your PMs with sarkastic commentary as he feels it is needed. The IM, to whom you may bring concerns, is @Devotary of Spontaneity. I plan to begin this game in roughly one week’s time, on Monday 30 May at 10:00 PM EDT (UTC -4). Should rollover change prove necessary, or an extension due to untenably low player counts, I will make an announcement in-thread. Thank you all and I look forward to a wonderful game! Good luck to all! Quick Links: Player List: (Note: if you do not give me a character description, I will give you a bad one. Please make one )

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.

How is it that Copper Feruchmy is so useful? In TFE pg. 233, Sazed says that he has memorized 172 languages. But how would he be able to use them, even after tapping the knowledge? wouldn't he need to train and practice with them in order to use them in any practical situation? Also, if a copper Ferring or Full Feruchemist removes their memory in order to save it for later, wouldn't they just forget what it is exactly that they have the potential to recall?

Feruchemists can tap their attributes to gain greater abilities than would humanly be possible. So, since a Connector Ferring can increase their friendships with others, then if a Connector Ferring were to tap enough Connection while being near someone else, would that individual grow to like them more than would be natural? Would they get obsessed with the Ferring or "like" them to a zealous degree? And would the feelings of friendship stay after the Ferring had stopped tapping Connection, or would the formed Connections remain in place? Sounds somewhat creepy, actually. And that's coming from a Hemalurgic enthusiast.

I was thinking about the unsealed metalminds, trying to wrap my head around how they worked. I kept getting bothered by the fact that F-Duralumin is used when F-Aluminum appears to be naturally better and still doesn’t work. But then I had an idea. The consistent problem with unsealed metalminds is getting into the nicrosil metalminds. Even blanking Identity only makes it usable for Nicrosil Feruchemists and Ferrings, not just anyone. But then I realized there’s one other thing we know on Scadrial that gives ordinary people powers: God Metals. In fact, the one godmetal we can canonically confirm to do this very thing. I would posit that an unsealed metalminds is used to duplicate a nearby Nicrosil Ferring or Feruchemists ability, just like we’ve seen with the Allomancy grenades. Since it’s a God Metal duplicating, it has the same universal use option as lerasium. Or to use Brandon’s own terminology, it is pure Investiture Brandon Sanderson So one of the things people have been asking about a lot the nature of Identity and its uses for accessing other people's metalminds, and things like this right. And I hedged a little bit when somebody asked me... *inaudible*...send people into spirals of confusion, so I'm gonna clarify it for now. So, someone comes in and says, we need a blank metalmind, anybody can use that. I'm like, yes but, the reason that it's a hedge is that you need to actually be a feruchemist to access it, right, you can't just hold the blank metalmind not being a feruchemist, even though it's somebody else's investiture that's been blanked, right. So people keep kind of missing this thing. I'm hedging in the sort of, you don't quite have it, I've kind of dodged it, but I worry that it's just going to be confusing. So the issue is, you need two things from one of these. You need something that makes you a feruchemist, and then you need a metalmind that somebody else has filled with blank investiture, ok. Now if you can get pure investiture, that can be used by anybody, regardless, ok, you need it in pure form though. <snip> Arcanum Unbounded Seattle signing (Dec. 1, 2016) In fact, the Allomancy grenades should work similarly and simply not be noticed because no person is actively tapping an ability. What about Feruchemical duralumin, you ask? That’s a bit trickier. My theory is that F-Duralumin is used to make harmonium itself into a metalmind. Logically speaking, if any one can Allomantically burn a true God Metal, the same should apply for Feruchemy. After that, one can infer that it is possible to draw out other applicable traits than whatever Harmonium’s base is, which should apply to both Connection and Identity. The former already works with how Shards are always tied to their power and the fact that Lerasium grants Connection. The latter simply supposes that the ability to do Feruchemy is basically coded Investiture in your soul that allows it to do that, kinda like Breaths (which can be stolen by nicrosil Hemalurgy under similar terminology) As such, I propose two procedures: the Tapping Method and the Storage Method. Tapping Method: 1. Have your duralumin Feruchemist tap Connection from harmonium. Continue until it’s blank. If all goes well, you should be left with pure Investiture, unaligned to any master. 2. With this new blank slate, have the Nicrosil Feruchemist fill the Investiture with their ability. 3. After sufficiently filling it, have the Nicrosil Feruchemist draw back the pure Investiture. 4. Fill a nicrosil mind with the pure Investiture. That nicrosil is now coded like a God Metal and works for everyone a la lerasium 5. Have other Metalborn fill the nicro godmind with their own powers, saving it for later Storage method 1. Have the Nicrosil Feruchemist store their ability in Harmonium. This tells the Harmnium to copy that ability, like how burning a metalmind changes what the metal does. 2. Have the Duralumin Feruchemist store their Connection. This contaminates the nicrosil ability into thinking it’s always part of the God Metal 3. Have the nicrosil Feruchemist tap the harmonium and store the resulting products in a nicrosil mind 4. Fill the new nicrosil mind with the desired abilities There may be a few other variations, but the end result is a nicrosilmind that acts like a Godmetal. This can then be filed as full as the nicrosil can store, which would explain why medallions only store a few powers. If there anything I missed let me know. Thank you for coming to my TED talk Edit: Thinking about it, I don’t think God Metals work for Feruchemy in the same way lerasium lets anyone use it. It might function as a universal metalmind, but you’d need to be able to give it an attribute in the first place. In other words, have Feruchemy yourself. However, my points about nicrosil and duralumin still stand. Edit 2: You may not even need duralumin more than once. An exicsor could easily be harmonium tapped of Connection. Once you’ve got that, any nicrosil Feruchemist can use it by storing into Exicsor, tapping, and putting the hacked ability in a nicrosil mind.

So far, we know only a few things about the main protagonist of Mistborn Era 3. As far as we know, she will be a “brown Terris geek girl” who specializes in computer programming and has nicrosil Allomancy. However, what I’m curious about is if she’ll be a Twinborn. Her Allomantic power isn’t one we haven’t seen used yet, but that didn’t stop Wayne from being Twinborn with bendalloy. So that makes me wonder: what sort of Feruchemy might she have? Do you think she’ll get any resonance powers? If so, what might those be?

So, in short my question is whether there's any confirmation or indications one way or another on whether the lifesense of someone who holds Breath can detect the Investiture a feruchemist stores in their metalminds. For instance, if a firesoul left out a brassmind filled with a lot of heat, would that register to someone with lifesense?

So I was reading WoA and a thought came to mind. Vin was aware that aluminum was Allomantically viable from her time in the prison cell. A year passes and we even find that she’s been working on an alloy. But it made me wonder if she told Sazed anything about it. They were in jail together and she could identify the metal later on. If so, then Feruchemical aluminum shouldn’t have been too hard to deduce. Remember, Allomantic and Feruchemical metals are the same, down to the alloy mixtures If so, then it makes me wonder if they could’ve discovered unkeyed metalminds. Granted, this would be tricky since the effects of storing Identity wouldn’t be obvious. However, I imagine Sazed would’ve reported to the Keepers if a new metal existed. That’s a pretty big deal. Surely, one of them would take an interest and all Feruchemists get zinc for extra sleuthing. And once unkeyed metalminds are discovered, Vin gets a huge game breaker. She and Sazed already know about how Compounding was done. Vin could only get short bursts from the metals, but even that alone would be a massive gain. Unkeyed gold makes her basically invincible and would outclass even the duralumin-pewter trick. Unkeyed iron could give her a duralumin effect with steel pushing. Even something like a burst of unkeyed zinc or unkeyed steel might’ve been useful. And Zane couldn’t mimic any of this without a Feruchemist or stealing from Sazed. No atium? No problem. Just surprise Compound. That said, I am willing to accept that the process does have some moving parts, especially in figuring out Identity. But man, even lesser Compounding could’ve been a game changer.

This a little would you rather. Seeing Twinborn and Fullborn made me wonder about the in between area: a Feruchemist with one Misting ability or a Mistborn with one Ferring ability. Even if they can’t be naturally born, lerasium would probably work on the right subjects and Hemalurgic definitely would. Which made me curious : what could you do with the full lineup and a metal to Compound? So I ask you, which would you rather be and why? Which metal would you Compound? For the purposes of this question, no Hemalurgic spikes will be used: just Lerasium on a natural Ferring/Feruchemist but at the lower power level.

As we all know, alloys are pretty busted in the Metallic Arts. It has such favorites as Steel and Pewter. But since the pure metals don’t see as much love, I wanted to challenge you guys. If you had to be a Metalborn of pure metals, which would you choose and why?

There is more you can do with breaths than just using them to awaken non-sentient objects. In Warbreaker, we see Vasher help a girl forget a traumatizing experience somehow, using breath. Probably by teaching her how to store memories in breath since, furthermore, in Rhythm of War we see that Wit does just this uses his breath as a storage system for memories. But one of the most fundamental aspects of breath is that they can be given to someone else. So what happens if you give a breath that holds some of your memories to someone else? To me, it would make sense that they now have access to those memories. Probably, it would require the right Intent to let them- maybe you need to modify the Command a little bit. " My life to yours, my Breath become yours. See what I have seen" or something. But I simply refuse to believe that if you can store your memories in Breath, and share Breath, that you can't allow other people to access those memories. (And possibly you could even make some kind of projector that can be Awakened to display memories in the Breaths it has, given the right Command, but that's extra speculative and probably we won't see anything like that for a while). We don't know exactly how how storing memories in Breath works, so maybe I'm completely off-base here, but I'd like to speculate further- why does it have to stop with memories? If you can store memories, could you store other things in breath? Strength? Speed? This sounds a lot like feruchemy and in many ways it is, so it's possible Brandon might not have made it work this way simply to keep the systems separate. But what we know of the memory thing does sound a lot like use of copperminds, so I also wouldn't be surprised if there were other similarities. Now, even if you can use breath to store strength, I doubt you can use it to give yourself super strength like you can with feruchemy. There's not multiplacativeness. You can store 10% of your strength in a breath, which means you'll be at 90% strength until you retrieve it and you're back up at 100%. You wouldn't be able to ever be at 110% strength like you can with feruchemy. But what you could do with Breath is to share that extra 10% of your strength with someone else. If you allow someone who's already at 100% strength to access your 10%, they could be at 110%. But that means you'll be stuck at 90% strength unless and until that person gives it back to you. I just think it would make sense if Endowment's magic system allows you to endow others with your own attributes, and this theory seems to be consistent with what we know so far.

Gold compounders can become savants, which does allow them to heal from basically anything and they even lose the psychological cost of harm as well, since they can't feel pain anymore. Allomantic pewter savants also can lose the feelings of pain, but they can still die from extreme exhaustion or serious injuries, and they can't feel pain to warn them of those dangers anymore. My question is then, can they tap pain from an Unsealed Tinmind so that they can be warned of things that could kill them if not treated?

So every Feruchemist from before Rashek used the Well was turned into Mistwraiths. The Mistwraiths could only have offspring with other Mistwraiths. So would it technically be possible for the Mistwraiths and Kandra to carry pure Feruchemical potential? They can't use it of course, due to the 'blockage' that Rashek put between their physical and cognitive selves* But if they do, could it potentially be Spiked out of them? Or perhaps could there be a way to remove this blockage and make them human? *WoB

So good non compounding twinborn combos. We have crashers ofc. But some others are : A-chromium and F-steel, to leech someone at superspeed. A-Electrum and F- zinc , to see your future shadows and to have the mental speed to analyse your future using it.

I was thinking about Feruchemical Aliminum, trying to think of how it could ever be made useful in any Twinborn. The only use I had ever thought of in the past was combining with pewter and trying to “heal” into someone else. But then, I thought of one other crazy idea. I want you guys to look at my theory and critique it. To start, it requires two premises. Premise 1: Many Allomantic metals emanate effects from the Spiritual center of self This one shouldn’t be too difficult. From the Alloy of Law Ars Arcanum, we know that this is why steel and iron lines go to the chest. However, I believe it has greater applications. Questioner So, if we switch to Scadrial, and I had lined the inside of my hat with aluminum, I'm protecting myself from emotional Allomancy. What if I was able to use emotional Allomancy? Would that block me? Brandon Sanderson So, it's going to interfere a little bit. But the issue with that is, a lot of Allomancy is coming from center and going to head. So, you're probably still gonna be okay with the helmet... So, I'm gonna say, you don't want a lot of aluminum around you, but you could probably still make it work. Oathbringer release party (Nov. 13, 2017) Soothing and Rioting come from the chest just like the lines. I’m also assuming the same rule applies for copper clouds and the time bubble metals. This will be relevant later Premise 2: In the absence of Identity, cognitive behavior (thinking) can change the location of this center of self This one is where I stretch. We know that cognitive perception does affect spiritual expression, like how you can’t heal an injury you see as part of yourself. My theory has always been that if you had little to no Identity, you could basically replace your Spiritual ideal with whatever you imagined. Hence, a short man who burned Pewter with no Identity could imagine himself to be tall and he would heal accordingly. If we take Premise 2 a step further, it is possible that one could replace their center of self with another place they can see or maybe even just remeber perfectly. Already, this could work for some Twinborn. Coinshots or Lurchers could suddenly move metals in totally different directions. Cadmium Twinborn could summon their time bubbles over someone else. But the really fun applications are for Fullborn or crazy Hemalurgists. Compounding copper could carry Allomantic effects to a place you remember. The Lord Ruler could’ve suddenly dropped a burst of super Soothing without ever leaving the castle, as long as he had copper minds with his targets. You might even be able to go a step farther and trick the Spiritual Realm into letting you see targets. Imagine burning malatium and dropping a slow bubble on your enemy when they were getting a morning coffee. Probably works better for time metals, but you could argue the others do too. Alternatively, you could use duralumin-Atium and try to work across location. Mail your friends a coppercloud overseas. The final thing I should clarify is Connection. It may be that Connection handles your plhysical location instead. In that case, Fullborn can simply blank their connection via F-Duralumin: it only really hurts Twinborn. But I also didn’t mention it because I saw Connection as a broad strokes brush. It would remember which street you’re on but not your exact coordinates. In other words, the hack works in your line of sight. Personally, I’d rather let the Twinborn have it for artistic reasons, unless I’m missing some other contradiction Anyway, that’s my theory. Thank you for coming to my TED talk.

I decided to post this for fun. Don't know if this was already done but if not then now it has.

I'd like everyone to respond to this with what one allomantic and one feruchemic power they would take if they could choose and why? I just wanna see what everyone's thoughts are on the matter since there's 16 powers for each (no God Metals) and thus 256 possible Twinborn combinations. Now, I know this is a broad question so I'm actually breaking it down even further. What set of Twinborn powers would you choose for combat purposes, and what set would you choose for normal everyday life? Personally, I think A-Pewter and F-Gold are a nigh perfect combat pair, since you can get more Health stored up than a normal Bloodmaker (Not as much as a Gold Compounder though, ofc), but also have the added physical combat capabilities of being a Pewterarm. It would also make becoming an A-Pewter Savant far safer. As for normal everyday life, I think either F-Zinc or F-Bronze personally along with either A-Brass or A-Bendalloy. Probably F-Zinc and A-Brass. Just would make moving through normal life so much easier.

So, this is my first theory in years, and I maybe did two before this; also, English is not my mother tongue. Furthermore, I just finished The Lost Metal, and haven't given the proper time to research and revise WoBs before I write this (anyone does?). Therefore, I apologize beforehand for whichever mistake I make. Now, let's get to it: In Kelsier's epilogue, he thinks about how Hemalurgy "had proven ineffective on what he'd become. It held his soul and body together, but no more", and he had hope, "hope he'd be able to touch the metals he could see in the world all around him". We're going to ignore the question that arises, if he can or can't physically touch metals, and instead understand his words as "Kelsier cannot use Allomancy in his current state". Does this mean that Kelsier has lost his prime Allomantic abilities? Did it happen when the Lord Ruler killed him? I think that's not the case, though there could be some WoB that say otherwise. I think that, when Kelsier died, the ability to access Allomancy was severed, but not extinguished. Much more like the link between his physical body and his congnitive shadow state were severed. We know that his eye's spike is made of steel, therefore it lacks something to link body to mind and soul. That brings us to the following theory:I think Kelsier had another spike before getting his eye's, this one made of aluminum. And here's why: Aluminum, according to the chart in TLM Ars Arcanum, has the Feruchemical power to store Identity. Also, as a Hemalurgic spike, it has the power to remove all powers. Hence, the core of my theory is that he used some kind of Aluminum medallion to store his Identity there (though I don't know if a cognitive shadow can access medallions, or if there's a WoB explaining it), then got someone to move it to the Physical Realm and stab his body with it, we don't know where. BUT, as he was Mistborn, the aluminum spike removed all his former powers and, potentially, his ability to use his steel one to touch metals around him. That would also could explain why Lerasium wouldn't work on him, as Sazed says, since the aluminum spike would automatically wipe out the new powers Lerasium brought. So, that's my theory for you guys. I hope I made it alright. Comments, opinions and insightful responses from someone who knows WAY more than I do would be appreciated. Thanks everybody for reading this far!!!

Trellium (Or Bavadinium) is described as a silvery metal with a red cast, and dark red spots similar to rust. When heated, it gives off a full array of light with the red portion being expanded. Red though, has a very specific meaning. It is not known to be strictly associated with any one shard, but rather is the color of investiture from one shard that has been "corrupted" by the investiture of another shard. So why, then, is trellium associated with red? Well cause all the trellium we see is not just trellium, but hemalurgically charged trellium. This means that it is solid Autonomy-aligned investiture filled with ruin investiture. That sounds like textbook corruption to me. So that leads to a few questions. - What color would trellium normally burn for, when not hemalurgically charged? - If you were to use any nonscadrian godmetal as a spike and charge it with Ruin, would it develop similar red spots from the hemalurgic charge, and give off red light on the spectrometer when heated? If you were to use an Atium spike, it presumably wouldn't develop red spots since it wouldn't make sense to corrupt Ruin investiture with more Ruin investiture, and I'd guess the same is true for Harmonium if you could find a way to use it as a spike without it exploding. But what about Lerasium- specifically, is it different before and after ruin and preservation became harmony? - Does feruchemically charging godmetals produce a similar corrupting effect? If so, how does this apply to the scadrian metals? Does it corrupt both lerasium and atium (I don't see any reason harmonium should be corrupted), since you're putting a bit of ruin into lerasium and a bit of preservation into atium? Or does it corrupt neither, since it's aligned with the proper intent even if it's also aligned with another intent? And similarly to hemalurgically charged lerasium, is this different before and after the creation of Harmony? My guess is that feruchemy doesn't corrupt either, if it corrupts godmetals at all, since I don't remember the lord ruler's bracers being described as reddish.

If eating lerasium makes you a mistborn, could eating harmonium make you a feruchemist? Allomancy is considered to be of Preservation, since it is an end-positive art. Feruchemy is of Harmony, since it is an end-neutral art. Therefore, it makes sense that Preservation's metal, lerasium, makes people allomancers, and it makes sense that Harmonium would make people feruchemists. Of course, on this logic, it would seem that consuming atium should make you a hemalurgist, which it doesn't. But I don't think that proves me wrong, because hemalurgy isn't a biological part of anyone, whereas allomancy and feruchemy are.

Aluminum Feruchemy is particularly interesting to me since identity stores all of a persons attributes, connections, and investiture. If utilized like soothing or rioting it could potentially be used to enhance desired attributes, connections, and investiture of the feruchemist. I also speculate that an AA twin might be able to absorb identity from others since all that investiture needs to go somewhere when they burn it, and based on how it works feruchemically I wonder if it just doesn't store the identities of the metals out of reach when burned, but perhaps not for a twin. Hemalugically Aluminum blanks investiture which could be related Identity as well. So an AA twin might also act sumwhat like Peter or Silar in Heros, storing or copying parts of identity from others into their own Identity. We see something like this produced with Forgery. They could also potentially use full blown hemalurgy without the debilitating effects through mix and matching parts of Identity. Even the use of forgery on an AA twin could potentially be a means of adding additional types of investiture permanently. Yes I know this is just speculation, but what do you think?

If anyone can burn pure Atium to get it's allomantic effect , can anyone store youth in Atium too ?

So feruchemical bendalloy stores nutrition. But nutrition can be metals too. Our body requires small amounts of iron , copper , etc to stay alive . So is it possible that someone who's a subsumer ferring can store metals in thier metal minds ? If so could that be how the lord ruler was so powerful at allomancy, he was constantly drawing duralumin and other metals from his bendalloy metalmind and duralumin bursting them constantly. The biggest hole in my theory is ofc that tlr didn't have access to bendalloy but maybe he had a little bit of bendalloy created during his ascension and used that bit to craft a metalmind . Thank you

I'm super interested in Feruchemical copper and copper compounding. Can a copper feruchemist store muscle memory? we know compounding copper does "interesting things", could this be related to the Lord Ruler's perfect memory? If you combine both these ideas, could a copper compounder learn things extremely fast as the Investiture fuels the Storage function of the brain? For example, a copper compounder would only need a couple hours of practice to perfectly learn a sword stance and replicate it. Perfect aim, perfect form, so many possibilities.
