The compounding of pewter appeals to me more than most. The idea of being able to physically make yourself bigger and stronger with an invested pewter mind while also burning a non ferring pewter to allow you to use that strength to its fullest with the enhancement.

OMG the Michael Jackson 'e-hee' lol

Atium is already basically using an aimbot, Atium compounding is infinite health glitch

"Can you spike youth out of someone" Asking the questions no one else is.

Compounding is my favourite cosmere mechanic. It's exciting when you figure it out on its own, even more so when you think about the implications for later Mistborn entries, and positively mind melting when you put it in the context of 'hacking' other Investiture. Great video, this stuff always puts a smile on my dial.

Last week we were memeing with my friends that a fortune compounder, when fighting, would just stand still and wait for a random meteor to kill his enemies. That or something like Domino in Deadpool 2.

Zinc would be interesting. I think there's a WoB somewhere saying zinc compounding has the potential harmful effect of "an infinite moment of thought," meaning you accidentally flare it too much and get yourself stuck in your own head, or at least that's what it would seem like. But hey, more time to think about homework, yay!

I've always been fascinated by compounding iron. Just how heavy could you make yourself? Also, Sanderson has shown that there is conservation of momentum (at least to a degree) with feruchemical iron, so if you compounded iron to make yourself incredibly heavy, broke into a sprint, jumped, and immediately started storing weight, you should accelerate to incredible speeds. You also get proportionally stronger as you tap weight to support and move normally with the additional weight, so in a way it would be a bit like tapping strength as well, without the physical increase in size. Imagine the potential force behind a punch backed with compounded iron. I'd imagine a 1000lb fist does not need to be moving fast at all to cause some serious damage. And what would an extra 500lbs on your back be when you can walk just fine already weighing thousands of pounds? And finally, what if you REALLY pushed it. If you really compounded iron, could you generate your own gravitational field? I'd imagine there being some serious potential for something like that to be used by a scadrian fabrial in the space age.

Thanks for finally making it "make sense" as you've done with all magic systems! Very well done, can't wait for more!!

I think that compounding weight would be the most interesting/fun for a character to be capable of.

Based on how much I eat, I think the most useful compounding for me would be Bendalloy. Never having to eat or drink again? Plus being a Slider? Yes please! Though I’d probably end up being the death of all eating contests... 🤣

Awww mann! I just found this channel like a week ago and have already consumed all the videos! You’re far and away the best, most in-depth yet still understandable Cosmere scholar on KZfaq! Keep up the good work man!

I love that as many times as I've read all the cosmere books I still learn something from these videos.

What would happen with compounded nicrosil? Who knows what could happen if you compounded a divine breath or something like that, maybe you could make an insane power source. Other weird ones are things like identity and connection,. Could you become super connected and entangled with someone else's consciousness to the point where you're almost like a single entity, and what could powerful identity even do?

Since W&W 1 I'm being genuinely scare of a gold twin born compounding.

I started writing fanfic about a Chromium Compounder. Just because you’re getting lots more Fortune doesn’t mean it’s painless or easy.

Shoutout to plants, the original compounders! Photosynthesis and respiration work a bit like feruchemy and allomancy

Compounding gold would be awesome. You are almost unkillable at that point. No more medical bills due to being immune to headshots, diseases, etc.

Compounding has always confused me; thanks for this!

Are you just the Coppermind incarnate? Because these videos are amazing! I am always amazed at the level of detail and thought put into these videos. You also have a way of explaining things that makes it easy to understand. Really great work, keep it up!

1) This channel is incredible I'm so glad I found it, this is much easier to understand then scrolling through the coppermind, although I do already know lots about mistborn and stormlight its great to learn about other book magic systems without having to read them all. 2) Zinc compounding would be fun you'd basically be able to 'freeze time', without moving, and also this paired with compounding steel would be so op, because you could go hella fast but then have your brain keeping up with how fast you are going.

Thank you so much for this video! Compounding was one thing that never made sense to me even with reading the books and copper mind articles.

Thanks! You do a great job explaining the magic systems of the Cosmere! I needed a compounding refresher. It will be interesting to see how Brandon uses it in the future, there are so many possibilities

Assuming sufficient supplies, Atium, love me some immortality. If I have to get some myself, then Zinc for the practical applications of near infinite mental processesing, or Chromium, because luck is good, probably.

As always a great video!

Great analogy. I dig it.

love the video great work as usale tho i would like to know what you are thinking of working on next

I really appreciate this vid because I had such a hard time understanding how compounding worked I feel like it was one of the few things that wasn't explained well enough in the books

Good breakdown!

I just finished re-reading Mistborn (book 1 - going to make my way through the series again), and came back to rewatch this so I could better understand. :) Super insightful! Thanks Steve!

Great stuff Steve. More videos please. Double gold all day.

Compound Bronze for a perpetual adrenaline high and natural restoration to the point of always feeling well rested

I love this channel

Miles had it good, I wouldn't mind a couple hundred lives.

aeon EHe ahahahahahah I'm dying. That was spot on

I'd most enjoy the first one you mentioned, steel. Gimme that super speed!

Compounding is such a dope concept its my favorite aspect of Era 2

Compounding copper would result in the memory being "Copy and paste" rather than "Cut and paste"

A lot of people have said compounding iron would be good, but not a lot of people seem to have thought about just how much extra power weight manipulation would give to Pulling on metals. Imagine if an iron compounder used their body to destroy an entire structure, reducing their weight to almost nothing to fly into a building at insane speed and then emptying their metalmind at the last moment to destroy whoever it hit entirely, or being able to summon any metallic object to themselves, regardless of weight.

What a copper compounder could do? Greetings from Argentina! Excelent video!

I've said it before, I'll say it again: A con artist compounding Duralumin is one of the scariest concepts out there.

I have an idea for a possible version of hacking with Surgebinding and Feruchemy. If you use the surge of gravitation to increase the weight of a feruchemist, do you think that they would then be able to store that weight? If so, you could essentially turn stormlight into a feruchemical iron charge. You might also be able to use this to combat a Windrunner or Skybreaker who is trying to lash you by storing all that weight into an ironmind so you're weightless in whatever direction they lash you to. I don't know for sure if it works like that, but it would be cool if it did.

I love your videos.

It’ll be interesting to see if unkeyed feruchemy flakes will become a thing in the future of Scadrial. Metal flakes that have been invested with a tiny bit of unkeyed feruchemical power, enough to overwrite their effect when burned, made for mistings to gain feruchemical abilities of their metal.

I think double steel is the most interesting combination to me - you'd basically become the flash, with a bonus ability to fly

Another great explanation video Steve! Thanks for your hard work on my behalf, since I don't have the smallest Shard of time to research on my own. Question for you: What would happen if a Feruchemist stored and saved a bunch of metalminds, and had his imprint on them, but was then killed, say by Knightblood, destroying him in all realms? Would that make his metalminds open for anyone to use? Or would there be some kind of decay for that stored power since it seems to be tied to the individual? Thanks!

Honestly a steel twinborn might just be the scariest there is. Like you're basically dealing with the flash that can also launch metal at you stupidly fast. Gold twinborns, as we may or may not have seen, are also super freaky.

For everyday use I would compound zinc, as I could both influence people and think much faster, both of which I could definitely get used to.

My simple fan theory for compounding copper is that it could be that your memories just become much clearer and maybe even hallucinatory (imagine taping your knowledge of chemistry and finding yourself mentally back in high school chemistry). My crazy fan theory for copper compounding is that you end up gaining Preservation or Harmony's memories instead of your own.

I want to say steel compounding but I've already got a fear of heights so I'll go in the other direction and say Zinc so I can overthink things in milliseconds rather than weeks, or Brass so I can calm others down and stay cozy too.

Gold. GOLD. I could throw myself down the stairs with no consequences! It's all the perks of Edgedancing (minus the no friction) but without having to promise anything!

I want Cadmium compounding, just so I never have to worry about drowning or suffocation (since I can't really swim). It also allows for some diving though pressure is still an issue I guess. And because it's one that no-one else is picking. Also I guess, since you can fill your lungs (or is it just blood?) with oxygen, then you'd be really good at mouth-to-mouth resuscitation? Which is somewhat niche, but cool.

wax hax?

Imagine compounding Investiture. You could use unkeyed metalminds to receive an initial burst of power which you can then compound to become that type of metalborn for as long as you have metal. Imagine compounding Stormlight. Or compounding the ability to burn pewter to have infinite 8x strength instead of the usual 2x or 3x while flaring. I think that would allow people to reach the levels of power of the ancient mistborn and it might even be possible to go even further than the savantism we've seen so far.

I’ve always been interested in both Aluminum and Duralumin, so it would be cool to see what effects compounding would bring

I think with Compounding and Twinborn Brandon brought the Power Scale really nicely back into a more managable ammount. Especially giving allomatic gold and aluminium/duralumin a lot more value. I love the Idea of Compounding even though I feel like it turned out a bit strong. Compared to the other magic systems, a fullborn or even a twinborn with the right combination can go ham (no not this ham) with the Power Level. I wonder how that will affect the cosmere once we see major crossover. I mean a Steel Twinborn could get extremely fast so I wonder how could even stop them.

Well, this got me thinking. Different amounts of investiture produce different results right? that is why some allomancers are stronger than others, in raw terms, or why a certain someone using a certain somethings can suddenly do feats of allomancy on orders of magnitude greater than anything else. I imagine for example that the stormfather's investiture is much greater than other spren's, so thats why bondsmiths have powers on higher scales than other orders ..so compunding aluminum may be how the bands of mourning where made no? incredible allomantic potency by investiture increase

Idk, maybe compounded copper could be useful. Like, if you burn a coppermind, you gain a photographic recollection of all the memories in that coppermind.

Pewter would be nuts!

I've been really curious since the first ars arcanum of wax and wayne: when Khriss drew connections between twinborn and the radiant surges, what does that mean for the radiants? Like specifically: twinborn with matching metals can compound, but even the ones who can't compound have distinct advantages in some circumstances. Do the radiant surges work the same way, with some combinations being "more compatible" than others? Or because each surge can only combine with 2 others, are they always guaranteed to have the "compounding" equivalent? We have evidence of a compounding equivalent with windrunners, i think, given that one of the lashings seems to be a mixture of the other two (in my eyes). What about elsecallers? Or lightweavers? Heck, edgedancers?!

Playing a Mistborn D&D campaign and my plan is to compound chromium. Let’s hope we survive that long.

What I’m curious about is what would happen if a Mistborn tried to Burn an Unkeyed Metalmind? It wouldn’t Compound but could they access the Feruchemical attribute?

If you compounded enough Connection could you steal magical abilities from other people or gain location specific magic?

I was wondering, if someone were to eat a specific food and then store it in a bendalloy mind and then compound it, would the specific food (it's calories and nutrients anyway) be duplicated, or would something else happen? If this theory is true, then copper compounding could potentially duplicate memories, allowing you to have multiple sets that you can either use to refresh your own memory of that specific subject, or you could place them in an unsealed metalmind for someone else to tap.

Also, Tin Compounding is somehow the only one idea of the base 16 which didn't get mentioned in this comment section so far... so, let's talk about it a bit. A double Tin Twinborn would easily be able to store some senses that Allomantic Tin provides: if your hearing is what bothers you of all 5 emotions, then you can make it as dull as that of a normal person. Now, it doesn't work that way with sight, but you can still just do the Spook spectacle-famric trick with a less thicc piece of clothing, if it really gets to you. Now, imagine being able to compound ANY of the 5 senses, going ZOOM anytime you wish, or even tapping your coumpounded sight tinminds while burning allomancy to both become a telescope AND be able to see in the dark more easily. Wow. And I'm not even talking about becoming a better --more controlled-- version of an allomantic tin savant. I mean, it looks like x2tin is an overly underrated combination, but it's also any Tineye's dream... being able to control the senses you get by the most part.

I like to think that compounding copper would make those memories much more vivid, or more likely to linger in your mind. Like how you remember some things much better than others and some memories are much more important than others. It would be cool if compounding copper would be able to make memories like what cereal you ate last for years and stay front of mind. Identity could just make your sense of self much stronger. Make you more you, if that makes any sense. I like to think that compounding anything could do something, even if I'm not sure what it is.

Constant compounding of copper is interesting. It's not like you get back more memory. I think it just gives you that memory permanently. Like you store all your memories in a coppermind, and then you burn it to have an eidetic memory

Gold compounder definitely I would love that

So what if I was twinborn, and both of my metals where pewter. Say I have two metal minds with stored strength in them, I burn one and get the compounded strength, but could I then tap the 2nd one to increase my muscle mass? and assuming I can is there a certain oder of operations I should do? should I tap the metal mind first to increase size and then burn the compounded metal for the most efficiency?

What if you were to lets say compound Steel to get a super speed boost but at the same time burn duralumin to strenghten the allomantic flow of investiture into the feruchemical steelmind? Like having the generator wired up to the crank flash light but then have the generator overridden and connected directly to a powerplant

Iron compounding. My allomantic yanks would be insane. Could probably rip hemalurgic spikes right out of people, especially if I could store my iron allomancy in an ironmind and tap it for a very big burst.

If I recall correctly smuggling Stormlight off of Roshar is pretty desirable by some. One would think that the vehicle for Stormlight, at least without a bonded Spren, is a Rosharian gem. Easy enough to come by, per say, but compared to something like breaths which just inherently live in you that'd be easier to move. Breaths cant be transferred in the same way, though, as we know. Alumancy is probably the easiest because the metals exist on other planets so you don't really need to bring anything, but are restricted to the genealogy of the user. It seems that Stormlight is the best because its closest to a "fuel" without the user having particular requirements, using a fabrial or similar device.

I would compound atium, because immortality, if any existed. out of normal metals though definitely bronze. giving myself what would essentially amounts to more time to be alive as well as meaning I'm never tired again? definitely extremely useful in the modern era. (now I know how Brandon writes so fast; there was no bendalloy, just insomnia)

I'm most interested in the effects of identity and connection when pared with other magic systems

Dunno about what compunding ability i want but ihave to wonder what happens to the innate investiture of a feruchemist if their metal minds are taken and burnt. if a piece of their "soul" is whats stored in the metalmind, what happens to that unaccessible investiture after the metalmind no longer exists?

I'm not writing a comment about my favourite twinborn Compounding combination(which is double-electrum, by the way), but I have a theory and I think it can immitate compounding in a certain way. Now, what if a Pinnacle gets affected by emotional allomancy while storing? I mean, it should definitely be possible to affect a Pinnacle, either helping him with storing Determination or the other way around by Soothing/Rioting Determination and Depression.... if it really works this way then paying some street rioter kids would be more than worth the theoretically infinite supply of Determination without the need of constantly buying new electrumminds... Man, this might turn out to be more overpowered for this attribute than actual Compounding, considering the costs for electrum and soothing/rioting.

Oddly enough I think Duralumin might be one of the most oddly useful for certain professions. Or hacking magic systems. Having the ability to store and use huge amounts of connection would almost certainly allow you to effectively become native to a certain location. Tap enough connection to become Selish for instance and you may become able to access any and all of the arts there at different times. But being able to connect to a location would be useful for more mundane things like trading or diplomacy. If I had to choose however it would be Iron. Relatively total control over your weight would be good and overcomes the biggest limitations on a Lurcher like it does for Wax as a Coinshot. And IF (big if) you can survive increasing your mass enough you may just have figured out a way to produce time dilation. Not sure if this is a good thing but it would be fascinating to see.

With regards your comment about burning the feruchemical steel not also giving the allomantic version of the power, didn't Miles talk about seeing his gold "ghost" when he was burning the gold for compounding? It's been a while since I last read Alloy of Law so I could be misremembering the context for that, and maybe something else was going on.

First, a great video. Secondly, I play with my friends in the RPG Mistborn and I wonder if it is possible to allomoantically steal someone else's metals (with a leech?), And then, using the feruchemian personality, to take those metals and burn them? To gain awake strength (as MistBorn or hemalurgy?)

How much steel do I need to compound to turn into a black hole?

I was always under the impression that compounding also made your allomantic abilities much stronger for example if you compounded steel could you move at super speeds but also throw out duralium level steel pushes?

I'd love to see a zinc compounder as a villain

Compounding fortune sounds awesome ngl

I know this is late but I have to ask, what about compounding with hemalurgy. Like what if an allomancer burned a strength charge iron spike or what would happen if a spike was used as a mine before someone tried to use it in hemalurgy.

I think that compounding zinc for heightened intelligence would be awesome! Never again fear the difficulty of learning a college course.

What would happen if an invested metalmind was made into the alloy version of the metal, like a coppermind into brass?

Bendalloy for nutrition would be incredible in a very non complicated way. Just eat one perfectly balanced healthy meal a week then not worry about eating your greens haha. Be good for workout routines! I thought about Electrum for determination, but I don't think having vast quantities of determination would be a good thing possibly.

Theory/ question, would a twin born tin user compounding tin get the enhanced senses of the sense stored in the metal mind, or all of them more powerfully than normal?

Could compounded aluminum perhaps burn out your ability to be a ferring , misting or both?

Id like to compound trellium/bavadinium; because the effects are unknown.

so if burning a metal mind fuels an ferchemical attribute, does that mean feruchemy changes the identity of metal itself, so when you try to burn the metalmind you can't use it to fuel the original allomantic power.

Gold. No contest. I would always be able to heal myself as long as I have some gold on me.

Chromium compounded novella would be FUN

Definitely compounded Duralumin!

1. Is compounding effected in any way by the amount of Feruchemical attribute stored in the burnt metal? i.e. does it make a difference if I burn a metal mind storing 10 hours worth of attributes vs 100 hours worth the attribute? Another way to ask this question is- is compounding additive or multiplicative? In case it's latter then we can exponentially increase an attribute by burning a small amount of metal mind, store the attribute in another small metal mind, burn that and so on and so forth. This way one can obtain REALLY high yield out of small amount of metal. 2. Related to pure Allomancy, does strength of Allomancy changes the consumption of metal? We know that flaring a metal will increase metal consumption. But does Elend, who's Allomantic powers are stronger than, say Vin, burn metal faster?

When burning the metalmind with allomancy, does the metalmind get consumed? That is, does the twinborn have to replace their metalminds periodically? Also, can they still burn the metalmind for the allomantic effect (maybe the Intent makes a difference?), or do they need to ingest the metal as usual to access that ability? You mentioned that compounding Atium has diminishing returns. Do we know of any other compounding that behaves the same way? If not, what makes Atium special? Anyway, your channel is amazing. Keep it up, man!

i think id like chromium because compounded luck would (theoretically) see me through so many situations. someone swinging a sword- oops they missed a coin less than a centimetre away trying to impale me - oops it missed my mum finding out i didnt do my homework- she forgets other than that id think atium of i can burn for instant health, id become undying couldnt you tecnically just store sense of pain in tin and constantly burn atium to become the ultimate fighting mahcine

Could a Brass compounder store the heat that would be burning *them* to safely immolate everyone around them?

Electrum. I could have INFINITE Determination hehe
