I've been buried in Feruchemical research for fanfiction reasons, and now I can't go two minutes without thinking how much I'd like to be a feruchemist. There are so many practical or just underrated theoretical applications. Firesoul Human Torches, Duralumin spies, SoulBearer enhancement, Some kind of Forging but for Trueselfs, etc. I can't wait for them all to be explored further.

Rashek has disliked this video.

"You could use surges without bonding to spren... Sounds familiar?" I thought about it for a second and then it hit me like a truck. That would probably be one of the smartest things Brandon has ever written.

Windrunner spaceships vs Feruchmy starships... Mistborn era 4 theory

Your preparation and research - for the theories, jokes, science etc + editing makes for probably one of the best if not the best Cosmere channel. Keep it up!

"...and Kaladin can make poor life choices and cry."

"How about bingeing on my old videos?" Ha. Joke's on you! It's how I got to this one.

Now I'm just imagining Lift with Subsumer power also - OP af

That explains it I'm a Pinnacle , in saving up all my motivation then tap it one day before the exam.

An important thing you didnt mention is that when you stop filling or tapping a metalmind you return to your default state. So if you stop filling or tapping an aluminummind then you return to the amount of identity you were at when you started.

And he's back!

Eventually Feruchemy could bring about a dystopia a la the matrix where they use each other as batteries forcing people to charge up metals to be sold on the open market. Maybe the poor will sell their mental speed or physical strength like we sell plasma. I honestly think Feruchemy is the coolest magic system in the Mistborn series, and Sazed is probably my favorite character in the first book.

“And Kaladin…makes poor life choices and cries.” Shots fired at my boy Kal. 😂😂😂

Out of all preseted theories, this one 11:06 concerned me the most :DD Btw. Kaladin with a Electrum metalmind could some day become an unstoppable one-man army

I appreciate the restraint you showed when theorizing about taping the relationship with someone's mother.

Feruchemy is my favorite of the metallic arts and I wish we got more of it. I'm hoping there will be more of it in era 2, which I'm about to start

Really excited for this video:)))

Love the way you make these videos. Very cheeky

I'm really enjoying these videos. I'd love to see one exploring how Feruchemy and Allomancy interact. It would also be cool to see a video exploring theories on how something like Stormlight or Breath could be used to power Allomantic/Feruchemical abilities, or how a surgebinder would recharge their investiture on a planet without highstorms/Stormlight

Some nice, simple, funny edits when clarifying 'tap'. Well done

This is great I wanted to do one of these but yours is better than mine would be. Great job.

I should probably write some fanfiction just to see how far I can push the abilities of the metallic arts in terms of creativity. Like maybe steelrunners producing sonic waves at their foes.

This video just made my day with all the theories :)

Is it bad that I’m feeling genuine excitement?😂

A few thoughts about the last one. Firstly, you said that Connection may be able to connect to individual people. Perhaps this is somewhat like the gemstone in the pommel of Shardblades, just perhaps more powerful. Secondly, this might also be something like the Honorblades, which do not have Deadeyes (i assume. We havent seen them in the cognitive realm, but the spren immitated them, not vice versa) or spren, so it might be something similar. It might be the same as something Identity. I also belive a Compounder potentially might be able to create something similar to a Nahel bond with a spren. Like a chasm fiend perhaps, or would it be more like a weaker knights radiant, one who may not have sworn any oathes. Just speculation, but it’s fascinating how these things line up

The "if they get sick while storing health" one I think may actually have been brought up in Era 2, sorta. I think he gets wounded, and isn't able to heal, because first he'd have to store health and that would end really poorly in the state he was in, and his goldminds were empty.

And a compounder video. Let’s go.

as a biologist i love the 2000 theorys in this video

"make poor life choices and cry." Yep, that's Kaladin. I wish he'd be happier

Oxygen and glucose combine during aerobic cellular respiration to create ATP. So it’s not storing that. Also I get the impression bendalloy stores other essential nutrients not just glucose. On a side note bendalloy is woods metal which is and alloy of bismuth/lead/tin/cadmium

Could a Steelrunner, using the surge of abrasion, basically become the flash?

Yay! I love your videos man you’re my favorite cosmere youtuber. Hope all is going well for you and your family during this pandemic, very glad to see you posting videos again! You planning on any special videos in preparation of RoW ?

i love the slamming on kaladin the paladin

Huh with the Atium we have now seen being a Atium Electrum alloy, I wonder what True Atium, does or if it can be used by Feruchmy at all?

As for the weight feruchemy power influencing how much the user is affected by the Higgs field is a neat theory, it seems unlikely to me. It's an remarkably small portion of your mass that you get directly from the Higgs field, only something like 1%

The idea of storing or magically taking away someone's identity combined with the philosophy that we are the sum total of our experiences has some interesting connotations for the Justice System of a given world. What if instead of execution or life imprisonment, their identity was blanked away? Sealed in a metal mind and locked in a vault while the body and soul went on to live a new life.

Feruchemy is the most awesome magic system I've ever read. Storing an attribute for later? That makes me think "why haven't I thought of that?"

I find it interesting how some feruchemical abilities seem to affect the whole body like iron or puter wieght and strength respectively but tin or copper can get very specific in whats getting stored.i wonder if you could access more specific applications through clear intent like in awakening breath (also somilar to himalurgic spikes intent aswell) E.g can you have big strong arms and weak little chicken legs

Man, this guy is so underrated

The reason a person doesn’t require extra strength with stored weight is that it’s not about their mass, but about their interaction with gravity. Think about lashing in Roshar, it works the same way, with the added bonus of being able to direct it elsewhere. This way other effects based solely on mass (like transfer of momentum) are not different and no extra strength is required to move you. If your mass changed, then a weightless person would be extremely subject to the whims of slight breezes and a controlled fall (which happens often) would be imposible. This is because even though they’re not accelerating downwards anymore (or just having a smaller acceleration), they’re maintaining momentum and are thus impervious to the small momentum gain from the wind.

Feruchemy is the coolest magic system of the Scadriel 3 by far

Feruchemical tin is HORRIBLY underrated. Tapping chronoception, proprioception, balance and kinaesthesia would give you a massive advantage in a fight (ever watched Muhammad Ali dodge punches?), especially while partially storing pain.

Gosh your videos are soooooooooooo goooooooood!

Just started your vids man they are awesome. And i love how you keep spoilers at bay !!!

I was thinking, if a feruchemist stored as much investiture in an iron mind as they possibly could, then were to melt it down and alloy it into steel, they would have a substance that could be used to make armor and weapons that could block or at least resist shard-blades and would be more practical than aluminium. I know that you could just store directly into steel, but then you'd have to store physical speed, and not weight, which would be a much larger sacrifice.

I wonder if the Feruchemical activity of Aluminium is less different than we think to the allomantic one. The basic idea of all investiture seems to be you have to forge some sort of connection with one of the Shards (or the innate in the world) and use their investiture. I think perhaps aluminium when burned allomantically basically burns the other metals but wipes your identity, breaking the necessary link to the Shard and their power. That is perhaps the anti investiture part of aluminium is always to do with identity, so it being able to work in Feruchemy is not a shock as the investiture all come from you, and not from the Shard. Just a random thought.

That Captain America joke was flawlessly executed

Next - Compounding!!!

One correction: Mass of an object IS all the matter that it is composed of. Weight is how strongly the Planet pulls the said object. Therefore, it is interesting what effects Skeemers will have in the cosmos. Maybe their powers will be used to create artificial gravity?! hmm

Well, stumbled across this and now I'm a follower. Hope to see one on Hemalurgy at some point!

Sooo, next Vid will be about Compounding? It is fascinating how Metalic Arts are designet to be usefull during SpaceConquest... Compounded feruchemical... basicly everything, plus allomantic steel, tin, cadmium, bendalloy...

I wonder if cadmium doesn't necessarily store oxygen but the stores something that provides energy for that organism during times when their usual energy source is unavailable. For instance (if it could even occur), would anaerobic bacteria store methane, carbon dioxide, or even lactic acid when in a primarily oxygenated environment? Or would plants tap for carbon dioxide when they weren't in an environment that they could obtain it naturally?

What I want the most is elecrum finally a cure for my depression!

All you have to say is tap the keg and we know.

Sazed may claim that Feruchemy is not as offensively potent as allomancy. I believe it's all about how you use it. Obviously a scholar wouldn't think his power set is that suited for fighting when a lot of the powers are more suited to exploration and learning. But I see feruchemy and allomancy like the difference of a manual and an automatic car. You have a lot more things to be aware of and control with feruchemy. But if you're creative and understand the percentages of what you're tapping and storing at any given time then you could be an extremely formidable opponent

So, a lot of people at the 17th shard have hyped up the radiants and how powerful they are combat wise. I agree with this somewhat, but I always circle around and remember the feruchemists. Can you really stop a feruchemist who is patient and devoted enough to save up a lot of physical speed, aside from counting on their investiture stores running out?

I've viewed iron and steel as akin to punching in boxing. It's split into weight class because boxers punch with their weight, throwing their mass behind a punch. Likewise with speed, the punch has more force/energy the faster the fist moves. I don't think they're really stronger, they just hit harder/faster. I have only read the first trilogy so idk what happens in era 2

When investiture is left alone for a long enough period of time, it gains a will of it's own. This made me wonder if leaving a full metal mind alone for hundreds, thousands, maybe even longer, would cause it to become sentient. If so, would the type of attribute matter? Like memory, connection, or investiture itself.

This videos are so fucking good. WOW

1:40-1:44 nearly made me spit out my breakfast

Speaking about bronze and changing ones identity, theoretically one could remove all of their important memories, but they would also have to store every single time the remembered it, or thought about it. So, removing a core memory would take storing hundreds or thousands of memories.

Can't wait for cyberpunk feruchemists who're covered in piercings

Only read Mistborn the first saga. I’m about to start reading the Way of Kings next month and I’m very excited. Hope to come back to this when I find out what shards are lol. Should I know shards from Mistborn? Maybe some metals are shards? If anyone can answer this without spoiling Stormlight archive that’d be greatly appreciated

14:10 HONORBLADES!

One other thing I was wondering about; if you worked out, there by damaging your muscles as is natural for exercise, and you tapped feruchemical gold, and you viewed yourself in the right state of mind, could you become super muscular really fast?

There was a guy in...one of the world wars, I believe, who suffered a head wound and was unable to and lost the necessity to sleep as a result (and lucky for him it didn't have the same sort of negative effects on him that a normal person would suffer if they just stopped sleeping). Anyhow, yes, he had to eat like 8 means a day to meet the extra caloric demands that staying awake perpetually caused.

Welcome back !! ..... explain how compounding works next

Era 3, 4 and 5 (if he does a cyberpunk series) is going to be lit. Not storm-lit mind you, but lit none the less...

OK, so we both want to tap Chris Evans. Glad we're on the same page here.

Would a feruchemist be able to essentially "become" different people if they stored subsections of their experiences in different copperminds? They could then switch between them at will by filling/storing certain personalities.

This video is just filled with wonderful puns

What is that figure to you left and where did you get it? I would love a tour to see what other cosmere goodies that you have.

Could an aluminum feruchemist force themselves onto a shardblade? If they can make unkeyed metalminds of any kind, couldn't they do the same to a shardblade containing metal?

This needs another video on the spiritual section. These are some interesting theories.

ahhh just nerding out....i love it....

imagine using an unsealed brass metalmind in a gun to shoot it and force the enemy into pouring their warmth to the point they freeze to death.

Not just twins. Even if you made a batch of perfect clones and tried to train them similarly I'd argue that they cannot share the same metalmind because while they share the same genetics, they will no doubt have differences in their spirit webs and cognitive templates as time goes on. The only time they could possible share would perhaps be the first few days after birth before their own sensations and perceptions of the world take begin forming their own sense of Identity. A person would be composed of characteristics in the sacred number three: - Physical body (Genetics. This would be the same especially in their youth. Epigenetics may play a role later based on their lifestyles) - Cognitive template/shadow (Self-visualization. This would differ the moment the kids recognize themselves by the different names their parents call them and then further over time as they learn different skills, hobbies, professions and just become different people altogether. ) - Spirit web (This is known to change over time, for the good or for the worse I think? Just having different friends/acquaintances can provide unique bond and different life experiences/traumas may result in unique strengths and cracks) Basically, imo, even twins are almost equally different to each other than they are to non-family members. That was a lot longer ramble than it felt in my head.

Feruchemical gold doesn't do well at healing diseases, but could feruchemical brass? Could you increase your body temperature enough that it would kill any bacteria, viruses, fungi, or parasites that could cause illness?

5:12 Or perhaps this is something that can be countered with Zinc. A steel Ferring would then be rather limited in their abilities, only able to run along flat ground with no obstructions. A full Feruchemist would be able to use mental speed to be able to make decisions at high speed and react to obstacles. This means that a full Compounder like the Lord Ruler would basically have the capacity to be The Flash if they bother to store all that speed on themselves, and also can get past the burning and friction thing. Oh shit wait, gold compounding and shit loads of pewter could probably get around that. Tho surely there would be an upper limit where the gold can't heal you fast enough to recover from the damage caused by the speed. But in a vacuum.....and applied to a mobile object like a spaceship....and with a mobile speed bubble....oh shit FTL travel. Another comment mentioned that tinminds could store the perception of time, which could have the effect I mentioned zinc could have, cuz I'm fuzzy on if mental speed would actually work like that. And yeah, brass would also work to counteract friction.

A full mistborn/feruchemist has to be the most dangerous being in the cosmere just short of the shards. Imagine coumpounding mass and creating your gravitational field

What do you think would happen to the power stored inside of a Feruchemical metalmind if the metalmind were to break or be melted down?

You mention mechanical Feruchemy access a few times and I have a theory on how that could work. Perhaps if you compounded a Feruchemical attribute near Harmonium it may begin producing that attribute like it does with Allomancy.

Hear the copper part. Mind instantly decides we won't sleep tonight

Do metal minds of rust-able metals still rust when oxidized? If they do, is the power in them lost, is it inaccessible, or does nothing change to the power?

Yes sunburns, because it's radiant damage. No other types of burns though.

Wait, are the honor blades metalminds? Storing radiant powers between desolations for use during the fighting.

love ur videos

So I was wondering, Miles' metal minds are spiked into his body, but his body doesn't reject them like it does other objects. Do you think that this is because he's a savant, and is able to control to some degree what his cognitive aspect says should be healed, or maybe since the spikes are filled with investiture, even if it is considered his own, that interferes with his ability to push them out through healing them?

your theories about bronze were hilarious

RoW SPOILERS ahead! Could one use raysium to separate a small piece of a metalmind, then carry the small piece and use it to tap from the larger piece? If the metalmind is too strong to be separated, maybe melting the metal first will make it easier to separate with the raysium.

An unkeyed brassmind could be used to make an air conditioning unit

How much time do you think it would take a feruchemist to fill a piece of metal with enough investiture to equal that of a shard-blade?

If Taravangian was on a dumb dumb day could he tap a metal mind that would boost his intelligence in some way and would it work? Or the curse of cultivation would be stronger negating those effects?

What is the difference between an unsealed metalmind and an unkeyed one?

The more i learn the more over powered the lord ruler becomes

Sunburns are caused by UV radiation, not heat. Storing heat wouldn’t affect sunburns, but would help with heat stroke.

Great content as always! Do you have any idea when your video on Hemalurgy will be coming out?

I think anything one healing can do, another could conceivably do too, considering it all works with the same mechanism. So I think a Bloodmaker could transition fully with the power, and in fact I think anyone receiving healing would just get that as a side effect, as in some of the Investiture used for healing them would go toward transition. Also, appropriately, gold is a transition metal :D

Can Nightblood be used as a metalmind?

“Any sufficiently advanced technology is indistinguishable from magic.” I wonder if Adolnasium was a descendant of a super high-tech race when creating everything and all of these Shard powers are just programs to manipulate the nanomachines - quite similar to the Numenera setting. Yolen and everything else was created by him, but he could have been someone older than that - similar to dragons in the eyes of ordinary people of Cosmere - since dragons totally manipulate matter and totally know about science and quantum stuff.
