Does the amount of Feruchemical storage I’ve Invested into a piece of metal influence what happens when I then burn that metal for compounding? If compounding involves tricking Allomancy into accepting a non traditional “key” for drawing forth Preservation’s power, then do I need any more than the tiniest bit of Feruchemical Investiture within my compounding storage metals in order to perform compounding at all? What, in such a case, would then happen to my pre-existing Feruchemical storages? Would they be “refunded” to me? Would the Investiture merely return to Preservation and Ruin? Would it increase my compounding rate, output, or speed? Just some basic questions about the basic hack of Mistborn.

Let's come up with some good uses for Compounding Chromium (basically, infinite luck)! Here is the list so far: Close your eyes, reach down, and pick up a conveniently located Lerasium nugget. - Me The windshield wipers and/or turn signal happens to be in time with the music. - Snoopy You don't run into trees, a la Intacto. - ThirdGen Keep my eyes and ears closed all day and just rely on random whims to guide me, then see where I wind up. - Observer Compound all night to get lucky. - Frosted Flakes In a fist fight, tap to have your opponent miss all punches. Tap more to possibly make them miss and knock themself out. Close your eyes, tap and pick stocks. Skydiving parachute malfunction. Tap and keep trying the cord. High speed car chase. Tap to survive without any crashes, while every police car following does crash. Bank robbery. Tap and guess at the safe combination. - kaladamSB When people post, I'll add their ideas to my list.

Hi, I’m new and have no idea what I’m doing. Throughout the first Mistborn trilogy, we experienced Sazed’s relationship with his copperminds. He used indices and pnemonics to keep track of his memory sets within his metalminds, and we often saw him drawing on the contained memories for their information stores. However, we never saw him experience a memory in such detail as the Sovereign memory Wax experienced through the unkeyed coppermind coin in The Bands of Mourning. Perhaps this is a result of Sazed’s past experience reliving memories, or perhaps simply convenience in writing. Or perhaps the extreme experiential vividity of this memory is a result of compounded copper from the coin’s doubly-endowed creator. Perhaps compounding copper allows for the creation of super-vivid memories, not only never fading as Sazed’s did in his everyday coppermind, but also existing with photorealistic detail. Any copper compounding theory likely has to deal with the Lord Ruler’s purported “perfect memory,” which assuredly was the result of this sort of magihacking. Perhaps these ultra-strong memories are more easily divided among multiple copperminds, or a portion of them is able to be recalled and another portion left for when necessary, within the indexed, magically-enhanced mind palace of a worldbringer, keeper, etc. Anyway, a bit rambly, but there it is. Perhaps Wax’s coin demonstrates the nature of compounded copper.

So, let’s say that I, already in possession of the powers of Allomantic and Feruchemocal Nicrosil, were then given a steel spike, Hemalurgically charged with Allomantic Pewter. If if I were to place this spike in my ear, and then to store the investiture it endows me with inside a nicrosilmind, would removing the hemalurgic spike then still remove the power to burn pewter from me? If I were to place only a tiny, tiny piece of that pewter investiture within a nicrosilmind, and then to burn that nicrosilmind (lather, rinse, compound), could I then remove that spike from my ear, passing it along to someone else for free pewter, while retaining supernatural levels of pewter burning in myself? Or would this spike prevent me from storing such Investiture? Would it still remove it altogether, seeing that investiture as keyed and attached to the spike? If I were to compound and the remove that spike, and such removal took away my pewter, would the next wielder of my spike have supernaturally strong pewter? I would love to be able to throw people to the moon, but I’m unsure whether I’d like to murder someone on a potentially failed attempt to gain such abilities. Thoughts?

In the Bands of Mourning, we hear the legends of the Lord Ruler’s bracers, endowing anyone bearing them with Mistborn and Feruchemist powers. A single pair of bracers. Obviously, we eventually find that the Bands are a real creation of Sovereign-Kelsier, a single, long, tapered piece of metal composed of carefully mixed metals. But I would like to talk about the Lord Ruler’s /actual/ bracers. Not all of them, as he wore many. His atium bracers. The special ones. Those bracers served as both a feruchemical storage and hemalurgic spikes. There are three things I find very interesting about them. First, Brandon had to know that any astute reader would doubt the Sovereign’s identity as the Lord Ruler, given that we know what Bracers he bore, and we know that his special ones, the atium bracers, would be unable to store other feruchemical traits, even given what we learned in the book early on re: F-Aluminum and F-Nicrosil. We know what his bracers were, and we know they don’t match the legends. Second, Vin and Elend sold the Lord Ruler’s atium bracers. Atium bracers that could only have ended up in the hands of Ruin’s inquisitors or burned by some Mistborn (barring somehow a Kandra contract or a Seer getting ahold of them.) And we don’t know what /burning/ a hemalurgic spike does, but that the results of such a thing, of effectively combining with someone else’s spiritual DNA could have crazy results. And these bracers were either repurposed by Ruin or burned by someone, more than likely. Third, we still don’t know what the Lord Ruler stored in those bracers. He had all 16 allomantic and feruchemical powers already, and he could have used either the well of ascension or nicrosil compounding to give himself such strength in allomancy as to need no hemalurgic boost, unless he was perhaps seeking a slight skill boost. Was he seeking the powers similar to a Kandra Blessing? Or something else entirely? in other words, there’s still some more to wonder about. I’ve tried to link this to Marsh’s feruchemical atium spike in the few minutes I’ve taken to write this, but I can’t see how he’d have made use of Rashek’s bracers, without any access to Rashek’s identity. Anyway, that about wraps up my ramblings.

To my understanding, the way healing works in the Cosmere reverts oneself to their perceived cognitive self. This is why Kaladin's brands don't heal, yet Lopen's arm grows back. With gold feruchemy, it would seem like one would still age. Their stored up health can only heal them so far, and their cognitive self would age. However, if one was able to have an absurd amount of healing, like a gold compounder such as Miles Hundredlives, AND they considered themselves immortal, would they age? I feel it is a reasonable inference to say Miles thinks himself immortal, considering his mentality seen in Mistborn, especially after he mentally moves beyond pain itself. If he imagined himself at a consistent age, believing that his healing prevented him from aging, and he always had copious, near infinite, amounts of healing readily available, I think he would achieve immortality. Plus, I feel like adding hemalurgy into the mix would only increase his already insane healing abilities, especially if he had a Trell spike that had some sort of power along the lines of healing. Thoughts?

What type of twinborn would you like to be? Personally, I would like to be a chromium compounder, as then I would be able to be really lucky (Jackpot!). earning £10m every time I do the lottery. Lol, that would be so funny... Although gold compounder would be pretty good too... To see the full list of feruchemical and allomantic abilities, see the metal magic quick reference chart I made down below, or go to coppermind.net to find it. Mostly, I'm talking about compounders, but just about anything could be possible. Actually, being a lerasium allomancer and a soulbearer ferring would make your allomancy really strong... But that's just my thoughts. What do you think? Ars Arcanum Metal Magic Quick Reference Chart.docx

I have a few theories on this front, but the floor is open. The problem with any theories made, of course, is that we know so little about Spinning. First, and least interesting, is simply somehow managing to get them in a situation with no variables, allowing them to be killed. This of course assumes that they would not be lucky enough to avoid the situation. Second, somehow manage to use a combination of a Leecher and a Lurcher (sounds like a bad children's book) to remove their metal and metalminds. Once again though, we fall into the trap of them simply being lucky enough to avoid this scenario in the first place. Third, highly speculative, is to do with aluminium. As far as I understand it (correct me if I'm wrong), an Aluminium Gnat, far from having no effect whatsoever as is said in-universe, has the ability to completely negate all Investiture in the Misting's body. If this extends as far as Feruchemy, a Purger, as I would call them if I was right, would be able to walk straight up to the Spinner, completely ignoring their luck, and kill them. Perhaps, like copper, it might create a cloud with lessened effects on other people, but I'm just speculating now. Anywho, what think?

Hi guys. I have some really deep mistborn questions and im sure you guys do to si i decided to make a dep mistborn Q&A thread. Feel free to ask questions and answer questions but please only deep good quality questions. Thanks

Per WoB, "Well, the Lord Ruler--don't forget--could compound any Allomancy he wanted." Did Brandon mean to say that TLR could compound Feruchemy, or is it true that TLR could compound alomancy? If so, would that be referring to Feruchemical Nicrosil usage? I'm a bit confused, because as far as I can remember we don't have a known mechanic to traditionally compound allomantic abilities.

What does copper compounding do? I don't think it's actually been mentioned, so if it hasn't feel free to speculate. Since copper stores memories that will then no longer for in your brain, might burning a coppermind permanently engrave them in your mind so you remember them perfectly but don't have to forget them temporarily to preserve them? Would those memories be corruptible by Ruin?

The theory is straight forward. An allomancer can burn an unsealed/indentitiless metalmind that corresponds to a metal that they can burn regardless of any feruchemical ability. In support of this, I point out that Vin could sense Sazed's metalminds as if they were another allomatic reserve, but she was unable to burn them. I think that this was because the metalminds were locked to Sazed's identity. However the unsealed metalminds by the south scandrialians can be used by any one with the ability to use them. This, I believe, includes allomancers. This means that Wax would be able to burn steel metalminds filled with physical speed,Wayne would be able to burn bendalloy metalminds filled with nutrition. and Marasi would be able to burn cadmium metalminds filled with breath. This opens up some intriguing possibilities as the medallions and their manufacture spread to the north.

Hey Sharders! Just something fun. If you could have any Twinborn combination--including Compounding--what would it be? Allomantic iron and Feruchemical pewter, or maybe Allomantic tin and Feruchemical gold. So many combinations! I think it would be cool to have steel on steel. Edit: I'm sorry if there are already things like this. Man, sometimes it's hard to be original!

Guys, what, exactly, is the benefit of compounding copper? Memories, unlike something such as strength, are incredibly specific, so compounding them has no real benefit (from what I can see)

So I recently realized that two things I believed about Compounding are not necessarily true: Metalmind is burned all at once, resulting in huge burst of power (probably coming from all that talk about bursts of power) What's released is Feruchemical power I am not sure about #2. I mean, now I'm thinking it results in release of the attribute, making the body heavier/faster/whatever and then that unusual state of heightened attribute is stored as Feruchemical power. Is there even any difference? Can somebody explain #2 to me and/or prove #1 false?

Hello! This is my first post (other than my introductory one), so i hope it's alright. I did find the answers to quite a few of my questions already, so i only have a few of them left. I still haven't fully searched the wiki and the forums, so some of these questions may already have threads/answers, so feel free to link me the page as well as answer it again, and i apologise in advance. So, without further ado: MISTBORN 1) I looked up about compounding. It said you store a feruchemical attribute, then burn the metalmind allomantically to release a multiplied amount of the same attribute. After some searching, I found you can also apparently restore some of that same attribute after receiving it from the burn, answering my questions about Miles 100Lives. My question therefore, is this: If you have to burn the metal Allomantically to receive the attribute, why is that when Vin removes the Lord Ruler's EX-ternal Metalminds in TFE, he then turns old? Shouldn't he be burning a metalmind to achieve youthfulness, e.g. it should be in his stomach? 2)I found out that the Lord Ruler knew about all the Allomantic metals, and therefore could make Metalminds out of them all. Given this, he should be able to store his Identity in one of them (i forget which metal). I'm not sure, but wouldn't this allow him to utilise other people's metalminds? And therefore, he could have had teams of Feruchemists storing up age for him and then using them to stay young via compounding. ( I also found out that The Lord Ruler would have died eventually anyhow even if Vin didn't kill him) 3) I noticed there are a few koloss blooded humans in the Wax/Wayne books. Does this mean someone did the deed with a koloss? I'm all for each to their own, but dang. Or is it due to the third part of pillaging and plundering? 4) I'm currently halfway through Shadows of Self (but i have read it before and i have read BoM as well), but after the collapse of House Tekiel in AoL, what happens to Tekiel Tower, or doesn't it tell you? Warbreaker Just the one question here: I know it's either all or nothing with giving away breaths, but I'm sure I remember Vasher giving a few breaths to the Priests daughter that he and Vivienna rescue. I thought that this may be due to Vasher's experience, or due to storing most breaths in an object, giving away the few left, then restoring the rest after, but any official reason/better reason than mine? Stormlight Archive 1) When Syl turns into Kaladin's Shardblade/spear/weapons, and she gets hit by another weapon, does she feel pain? I think that is it for now, if i remember an urgent one I'll add it in an edit. From now on I will be summing up some of the notes I have lying around and try to get them post-ready for the theories forum. Also, just spotted Hoid again - coachdriver this time (SoS, for Wax). Thanks!

So, I've read on the wiki's among hearing it in other places that a Mistborn is capable of burning metals because they have more investiture than other people. So, say you had a Nicrosil compounder twinborn. He could store his investiture, then compound it to become either much stronger at burning Nicrosil, or even become a Mistborn. I've seen other theories of it letting you store the power you would have gained while burning a metal, but I don't agree with them.

This is my first topic... (hooray!) So if I'm overlooking something completely obvious, feel free to point it out. I think it would also be fun to add ideas from everyone. Stormlight Archive 1) Shardblade drop Shardblades have been summoned over extremely large distances with little or no effort. You think the command, and the shardblade appears. It presumably comes through shadesmar, based on how other things have been doing that and the fact that it's a (dead) spren. Now, what if you were to go to a VERY high place and summon your shardblade? The energy output would be greater than the input. You could even power a generator by repeatedly dropping a shardblade on it! Could this be draining some sort of energy resevoir from the cognitive realm... or is it draining power from the gemstones? If it needs stormlight, then the gemstones or the radiant could easily feed it that. 2) Antigravity lashing This has the same concept as #1; an object comes back down with more energy than it went up with. Say you were to do a reverse lashing of half an object's weight upwards. You then launched it somehow with a ton of energy. The object would go much higher than it normally would with the same amount of energy. However, when the stormlight ran out, the object would come plummeting back to the ground with more energy than it was sent up with. Yes, this uses stormlight, a type of investiture. However, if stormlight consumption is based on time, you could still have a higher energy output with a large enough force sending it upwards. This implies that there's a complex formula for how fast stormlight is consumed. 3) Spren = mass? Spren supposedly come from a thought. If a thought allows spren to be CREATED, and that said spren bonds with a radiant, and that spren takes a form of something, wouldn't it add mass to the world from a thought? You could generate mass (and therefore energy) by thinking! Granted, the thought takes some level of energy... but you could theoretically have a higher output. However, it's more likely that there's a very complicated process to spren and bonding that we just don't know about yet. Mistborn 1) Compounding You simply come out with more energy than you put in. That's very simple... Store the heat of a fireplace, turn it into the heat of a supernova! I've read another topic talking about how it can draw power from shards, so that's resolved. Warbreaker 1) Awakened breath consumption Awakening an object lets it run for a long time on a single breath. Awakening can convert breaths to kinetic energy. Apparently, awakened objects stop working eventually. Could this be using up the breath or the objects energy? Either way, would a harder task demand more of that energy source? If not, (which is less likely) you could make a monkey rapidly turn a crank for a very, very long time and convert very little breath into A LOT of energy. In that case, awakened objects probably use up breath or their stored energy based on how hard what they're doing is. 2) Color=Energy... Color is either pigment or the wavelength of light. It's almost garunteed to be pigment, as there are a bunch of problems with light. There's bound to be some problem with converting pigment to energy, but I don't know enough formulas to think of something. I want to know what you think! I need someone who knows what they're doing!

It recently struck me: More detailed analysis: Is there any WoB on such things? What are your thoughts?

While trying to get my over caffeinated mind to sleep last night, I found myself pondering the cosmere (as usual). Something occurred to me that I don't remember ever seeing addressed. What would happen if someone tried to swallow and burn a piece of metal that had a hemalurgic charge instead of a feruchemical one? Now, there are obvious reasons why this would be hard to attempt in the first place. Following the rules, an allomancer can't take just any old metalmind and burn it...it is keyed to the feruchemist's identity...so the only people who can compound are people who, for whatever reason, can use the same metal for both feruchemy and allomancy...twinborn, hemalurgist, etc. Assuming that this remains constant with the theoretical situation I'm positing, you would have to either: A: Take a shaving off of a spike already in your body B: Spike yourself, survive, and still have access to the ability to burn the type of metal the spike is made of. Method A sounds a lot easier to pull off...method B...almost impossible... I could easily accept that this is just not something that works...which is why it has never been addressed. But just for fun, what do you guys think would be the result of hemalurgic compounding?

Rashek's Allomancy was incredibly powerful. Far more so then even Elend, a full Lerasium Mistborn. His latent Allomancy appeared more powerful than a Mistborn flaring duralumin, orders of magnitude stronger than Elend. It is likely that he gave himself a more powerful form of Allomancy at the well, but it seems most likely that this would simply be a scaled up version of a Lerasium Mistborn. But from how he's portrayed, he's orders of magnitude more powerful. Why is this? Is he flaring Duralumin the whole time? This is unlikely, as it would burn out his metals too quickly. So my theory? Rashek was compounding Investiture. I suspect that he was storing investiture in Nicrosil, burning it then storing vast amounts of Investiture from compounding. He would then be able to keep his investiture (like his age and his health) at a steady burn all the time he was out in public. Thoughts? (And if this was posted before, I'm sorry!)

Some kinds of feruchemy when compounded seem really easy to get addicted to, when compounding of course. Stuff like cadmium (which I think when burning a metal mind, you feel more alive, or more oxgenated, but like extreme amounts of it), bronze, Gold, Tin if you're a masochist like Spook, brass, chromium (?), and bend alloy. Then you have the stuff that'd be weird to compound regularly like weight. Would there be other types of investiture that are addicting?

Hoid is both an Allomancer and a Ferrochemist. But please note these few things about him. 1. He didn't necessarily use the bead of Lerasium to become a Allomancer unless there was an interview that I didn't read. Regardless of whether he is a Mistborn or just a Misting, and similarly with Ferruchemy. It's still possible that he is compounding much like the Lord Ruler did in order to stay young. Brandon said "He did steal a bead of Lerasium off of Scadrial. If he were to make use of that bead, certain powers would have been gained." 2. He would likely be from Scadrial given he could gain BioChromatic Breath. Despite this many people think he is from Yolen. I will admit that I haven't read ever book in the Cosmere yet, but I'm almost done, and my theory makes sense; at least to me. 3. None of his powers are gained from Hemalurgy So little is known about the ability LightWeaving on Yolen, so to assume that he's from there and that it is heredity it foolish, so let's assume that like BioChromatic Breath, LightWeaving can be gained, or like Forging, it can at least be taught. The ability to visit Shadesmar can be gain in many ways, and the ability to manipulate it comes from practice. He uses Feruchemy to gain limited foresight, so he can know where he should be. This leads to my believing that he has lived through ages, maybe even since the shattering, though we know he isn't a Shard. It's quite possible though. As far as we know, Ferruchemy is strictly genetic, but being the oldest form of magic on Scadrial, it makes sense that he is from there, likely before the Rise of the Lord Ruler. His ability to heal and "bend time" could also come of Terris heritage. I don't think that he is a MistBorn, but rather a twin born of multiple abilities. NOT a full MistBorn and Ferrochemist though. Comment below with objections or support of this theory, I'd enjoy hearing what you guys think about it. -Java

So we know from the MAG that "[w]ith proper manipulation [of Feruchemical aluminum], it might be theoretically possible to tap someone else’s metalminds..." There have been some theories on this, with one of the prevalent ones being that a Feruchemist drops themselves to 0 Identity and then their metalminds are "unlocked," and/or that a Feruchemist with 0 Identity can tap someone else's normal storage--doesn't run afoul of whatever mechanism stops people from normally accessing each other's metalminds. Someone asked the former on Twitter today: Source: So that. Assuming that ":)" means yes, then I have had a thought. What's to stop an Allomancer from Compounding such an "unlocked" metalmind? This actually goes beyond whether Brandon's answering yes or no, though, since Compounding can do interesting things either way. Even if the trick is just letting Identity-using-Feruchemist access random metalminds, he could still Compound that metalmind if he could burn it Allomantically. But the first case is far more interesting, since the second is essentially just a streamlining of a normal "tap, then store". EDIT: Wait a second, the second case is not "essentially just a streamlining of a normal "tap, then store". It lets an Feruchemical aluminum/a<Anything> twinborn compound whatever his allomantic metal is, without the need to rely upon another Feruchemist being a willing participant and/or a Full Feruchemist. And there's no storing going on. Past-me had a brain fart... --- So the first case: Scene: We have an Augar named Amy who's feeling a mite ill. She calls her Full-Feruchemist friend Friendly Frank for a favor: "Could I have some Health, please?" "Sure thing," Friendly Frank says. So he stored Identity and filled up some gold with Health and took it to Amy's hospital bed. "Thanks Frank! You're a lifesaver!" With that, Amy swallowed the metalmind and sensed two distinct reserves. Choosing the unfamiliar one, she burned the gold and was flooded with Health. And so Compounding granted a Feruchemical attribute to an Allomancer FIN And, therefore, Augors are actually useful in the future, once they figure this out, since they'll just make a habit of buying Invested metalminds from full Feruchemists. All other stripes of Allomancers could behave similarly. --- Also, a "yes" would essentially confirm some variant of the "key-lock" theory we discussed back in the day. ------- UPDATE: Theory confirmed.

When person is both feruchemist and allomancer he/she can burn his metalmind and get an extra burst of characteristic that stored in it. This happen because this person access this power via allomancy, so extra burst go from Preservation. This multiplying effect looks normal for all feruchemical storages, except one. Coppermind. Feruchemist store memories in copper. If you compound copper, what will happen? It will stupid, if it just duplicate some of the information on coppermind. I have an idea, that when person compound his coppermind memories on it become more detailed. I mean that Preservation get necessary extra information from Cognitive or Spritual realms and give it to compounder.
