The part where it is told from external perspective, where we have no idea what she is pulling (or Pushing!) off of. If someone described what Kelsier was doing in his last fight, people who argue that Mistborn are basically Magneto, but we had his internal monologues to see just how it was to pull it off, and required use of both steel and iron. And that is why I think Vin was using both metals in that scene. What the hell are you talking about? Like yes, any force can be broken down into components, but that does not mean tangential forces are not real? Why do you think rope is taut once in air? It is because the tension of the rope makes it serve as sort of lever. I mean, when you are starting to rotate the rope, the objects is being dragged by the rope. You can literally try it at home. You don't seem to understand physics very well. Forget about rope for a second and look at gravity, which is much better analogue. There we have a central force (like in A-Iron) and it is quite well known that you cannot use such force to induce torque. That only works if the object is already moving, you simply cannot get it to start orbit you that way. Additionally, your image implies that the object is being continuously accelerated, which is well, not the case. Feel free, does not make you any more right. But there is no tether! How many times do I have to say it? When you have tether you are never dragging the object close, which is exactly what you do with A-Iron. It simply does not work like you are saying. I will try for the last time to explain why it won't work, using your image if you don't mind. Alright, lets take you image then and analyze it then. Assuming the circle in the middle represents hand span of grown human we can take it at about ~1 meter in radius. Then the trajectory has radius of circa 6 meters. So at any point in the trajectory, the tangential force will be 6x smaller than the force pulling the object towards the center. If you just start a pull at ~10 Newtons, nothing too fancy, the object will hit you in ~1.1 seconds, and no amount of moving your hands about is going to change. So you have to move to the side. Why am I not considering the centrifugal force? Because it is too small to do anything, even after 1.1 seconds, the speed generated in the tangential direction is tiny. The centrifugal force generated through the movement would be only 0.2, far smaller than the attractive force you are using to drag the object towards yourself. Even taking it into consideration immediately, it would mean still you have to move at ~5 m/s or something like that. So you have to move, specifically, you have to move in such a way that you maintain the distance to object as constant (or nearly so). So that immediately means you can get object to orbit you only if you are pulling at less than 20 Newtons (in plane) or so, because at that point you have to move yourself faster than humans can move (on their own). In our scenario, you have to be moving at ~5.45 meters per second. The issue of course is that when you move, it will change what is the centrifugal and what is tangential, in ideal scenario you moved in such a way that the original centrifugal direction is now tangential. You also have to modulate your pulls somehow, but lets not get into that. Now, how fast would the object have to be moving for the image to work? Well, we know that v^2/r = F. So if you are pulling at measly 10 Newtons, the object has to be moving at ~7.8 meters per second. Which is my entire point, you can use A-Iron to sort of catch an object that is already moving and capture it for orbit. But you cannot induce an orbit. And all of the above still neglects gravity, which would complicate things further (again, the rope does a lot of work). Since we are assuming that the Misting has hands apart to get as much tangential force as possible (for some reason, since as I outlined that part is basically negligible), that means they are ~1.5 meters above ground level. (for simplicity) Part of the pull force has to be counteracting gravity, so right off the bat, Misting must pull more forcibly than 10 Newtons, because 10 Newtons is force of gravity alone. Assuming the object will be orbiting at ground level, and keeping the 6 meter distance, we get that Misting must be pulling at ~24 Newtons only to overcome gravity, leaving 14 Newtons in plane for all the other stuff. You can make the plane force smaller, by bringing the object closer, but then you are losing on the already small tangential acceleration. So, the way you suggested simply won't work, moving hands around is not enough, you have to be basically running/sprinting to get it to the orbit. Of course, the issue is that compared to my simplified approach, the A-Iron force always points towards you, so to get enough tangential acceleration, you have to be moving even faster. Edit: To summarize (TL;DR): You have 2 problems, how to overcome gravity and how to accelerate the object tangentially to yourself. Overcoming gravity requires pull of minimum of ~20 Newtons, when the object is at certain distance from you, and you must always pull from a point higher then the plane of orbit. The closer the distance between the plane and the point of pull, the greater the pull force must be. The second issue is more problematic, because unless the object is very close (i.e. closer than circa 1 meter), then the tangential component will be always far smaller than the gravitational component and the centrifugal component. Hence you can achieve it only when the object is close. However, there you run into the issue that because of the gravity, the force of pull is quite large, and so the tangential speed is going to be faster than you can react most likely. And if it is that close, you would have to rotate your entire body to achieve the desired effect, rotating as fast as the object you are trying to pull like this (which @alder24 already pointed out). So no, rope analogy does not work, because rope is actively dragging the object (that is what is accelerating the object). You cannot create such effect with A-Iron, due to the fact there is only one central force being applied (whereas in the rope case there are two independent forces, the tension of the rope creating centripetal effect and the force generated by movement of the hand which creates the rotational component, A-Iron mimics only the first part not the second). You could in principle create tangential component large enough by extending your hands, and having the object very close (sub 1 meter), and the rotating yourself at equal speed. However, due to the fact that the pull has certain minimal strength due to needing to overcome gravity as well, you would have to be rotating at quite large speeds, which makes it problematic. For distances greater than 1 meter, the forces will be roughly F_grav > F_centri > F_tan, so the tangential component will always be smaller (and usually much smaller). For distance smaller than 1 meter it will be F_grav > F_tan > F_centri, however due to geometry of the situation the only way you get orbit is if the Misting starts spinning with outstretched hands, just as fast as the orbit is. You also have to balance tangential component against the centripetal component such that the object is accelerated only to the speeds which can be counteracted by the centripetal force, which is now quite small.

No, because you are wrong. All Vin did in that scene was Pull on gate, and Pull herself to the side (most likely dropping the Pull on gate at some point in the maneuvere) to dodge the gate that was hurtling at her. Very different from getting object to orbit you. Yes it quite literally is. Again, A-Iron cannot generate tangential Force, nor can it transfer it. It is literally not what it does. So from the start, rope is incredibly bad analogy. Yes, I can move to the side, to get Pulled object to bank. But I have to move about as fast as the object to get it to bank and not hit me. Again no. Your rope analogy is flawed at the core, so the diagram won't work as you imagine it to be. The only situation where it would make sense, is if the object was already moving, which I already said. If the object is at rest, then it will simply fly towards you, because the centripetal force will be far larger, and the object has no centrifugal force that would be counteracting it (since it has no orbital momentum), no matter how you move your hands around.

Yes, as you said, you create tangential force by pulling the rope and the rope then pulls the object at the end. And neither of these are possible with A-Iron, since the Connection is only spiritual, not physical. No. The reason rope works is because the force is transferred along it, so the tangential motion can happen. But there is no such analog in A-Iron. If you motion with your hand, or move the pull to distinct body parts you are minutely changing the body part to which it is drawn, but there is no appreciable tangential acceleration to speak of. Since you like ropes, it would be like if you would argue you can get object to orbit you when all you can do is drag the rope towards yourself. Because that is what A-Iron does. I think it is you who should consider the chosen example actually works, instead of drawing on imprecise analogies. Rope can create orbit because it can pull in the tangential direction. The rope does the pulling. A-Iron cannot create orbit, because there is no metaphysical rope that could create pulling in tangential direction, only Misting themselves.

Though, If you are not healing power back, all you are doing is transferring the (degraded) power to someone else. And because they are expansive, only rich people can afford them. Arguably that makes it ethically problematic (imagine what the world would look like if poor people had to sell parts of themselves to rich, loosing skills and abilities in process). Doubtful. Problem with Hemalurgy is that you tear off piece of soul, quite violently in fact. In SA we see what happens when you do that forcibly and it is not a nice result (though it was for Cognitive Entities). I don't think Twinborn would in any better shape than Ferring/Misting. I mean, there is no reason to think that Ferring is left better off than someone with no powers who 'just' gets attribute stolen. Ghostbloods have possibly had ~340 years or so to figure stuff out, they did not. They did not even manage to figure out that non-lethal spikes are possible (as far as we know). And the Set are currently destroyed, with their research either destroyed or confiscated. They will have difficulty just getting back to original level. Though I do expect to see more of Hemalurgy in Era 3, I just don't think that much progress will have been made. 'Same principle' is there the key to me. And I would note that being infused with Stormlight is sufficient to heal spiritweb damage, if you are Knight Radiant, because the bond is deeper there. There is literally WoB on it and I quoted it before. So yeah, how much is the power 'integrated' into soul, does play a role. So, F-Gold medallions which are 'mechanically' accessed power, that are confirmed to be in some cases more limited than 'natural' powers, could quite possible be limited in same way. I mean, they are quite similar. Priming: Cubes have to be primed by allomancy or feruchemy. Diffenet Misting/Ferring priming cube produces different effect. Fabrials are primed by trapping particular spren. Different spren produce different effects. Fuel: Cubes require pure Investiture as fuel (Harmonium which burns and is slowly burned in process). Fabrials require pure Investiture as fuel (Stormligh/Lifelight/Voidlight/whateverlight). Construction: Primer cubes require other parts outside of the Harmonium and priming user (seemingly some metallic contraptions and such, based on what we see in their airships). Fabrials requires metallic cages to harness/modify their function. Medallions on the other hand are far simpler, being basically 2-3 Metalminds in a trench coat. Yes their making is most likely somewhat complicated, but the complications are of very different kind than those in making of Fabrials/Cubes. You can make fabrial without any powers yourself, presumably you could also Primer cube (as it seems to require Harmonium and just mechanical parts), but you cannot make Medallion unless you have Invested power. It was a speculation on part of Ghostbloods and Moonlight, she never used it before and was aware there could be some risk. We don't know why she would not revert with time, much less how real the risk was. The Sorceress could have bunch of Dor jars hidden nearby for all we know. But you do have a point there. I suspect some form of limitation is still present even for Elantrians, simply because that is what Sanderson usually does with his magic systems. The more powerful they are, the more restrictive they are. Excuse me, but no. Most of knowledge of Hemalurgy comes from Ascension of TLR and now Kelsier. As far as we know, Ruin did not really share much information on it (outside of manipulating some people without their knowledge). Any A-bronze Misting can hear Rhythms of Metallic Arts, they have no idea what they signify, nor any idea how to exploit it. Scadrial is a bit behind when it comes to Realmatics, they barely even know about CR and SR, much less anything else. Again, no. Scadrial (and Ghostbloods) know quite little abou Realmatics. Kelsier cannot even get himself out of Scadrian system, and has to rely on spying/extorting Rosharans to figure it out for him While blank Investiture might have been known before, I doubt Ghostbloods know/can make it, considering how they treat unkeyed Dor as basically a nuclear option. If they had easy way to get more, there is no reason to treat it as they do. And since Dor itself is relatively 'easy' to get, unkeyed part is going to be the problem. Yes, mechanized use of Investiture, like what Southerners are doing with ships and stuff. And even then, Scadrial is going to be 'Earth' analogue in future Eras, Roshar is the designated magi-tech civilization in Cosmere. So then powers however accessed cannot distort things too much. WoB: You mean like how in Era 1 we had throw away line about how it ought to be possible for Allomancer to somehow burn metalminds, and that ended up basically working only in extreme edge cases (i.e. you happen to be born with the two powers, literally 1:16 000 000 chance, if not lower)? So yeah, I would not be surprised if pure-Investiture spikes ended up a dud. Not every idea works out, especially when you are trying to discover or invent something. Fair enough.

Thank you, I am blushing It is quite fun to discuss with you. I don't think this argument holds up. Just because the ability to tap and store is part of spiritweb, and 'knows' what it can do, does not mean that the person can do it. I mean, all of us have ability to do somersaults literally encoded into us, and yet most cannot Like anythings, ability requires practice, and in Cosmere also Intent. So I don't think you can tap or store without knowing what attribute you are storing. I mean the fact that you cannot store while sleeping strongly suggests that conscious Intent to store something in particular is quite important.

That would not work at all. Lasso works because there are two forces involved, one is the centripetal of the rotating object (counteracting the centrifugal force) and also tangential force accelerating the object along the 'orbit'. Both of these are transmitted through the rope. However, A-Iron only pulls towards you, e.g. it can only replicate centrifugal force, not the tangential force. Hence, A-Iron alone cannot help you force object to accelerate. Edit: Better analogy is planet rotating around sun, in that case there is also only centripetal force. However, there the original velocity of the objects was already present when solar system formed. Hence, at best if you were in vaccuum, the object already had some speed, you knew exactly what the speed is, and what distance you are, and you could modulate your Pulls with precision bordering on impossible, then yeah, you could do it. But that is just 'catching' something into orbit, not putting it there using A-Iron. And you can forget about doing it on the ground, there the object would simply fall, because A-iron could not counteract that. (Again, the rope does a lot of work). You should consider physics a bit more before making statements like this.

Basically the same reason as cometaryorbit, couldn't find one that would 'fit', and at the same time it is not too much of a big deal for me personally. I'd probably get something Kelsier-related, since I like the character quite a bit.

Spike would not be made, there is no Intent happening in the scenario you outlined. In the Spook case, Ruin supplied Intent, because it got actively involved in manipulating the person and making him spike Spook. Intent is always needed (https://wob.coppermind.net/events/2/#e209). In your scenario, that would be equal to that 'observer' somehow manipulating and forcing the first person to spike the second person. But if they just happen to see it, Intent is simply not there. Thank you Regarding Warbreaker spoilers

Wouldn't that just mean Shardblade cuts you as if you were non-living object? Because as far as I know, it does not 'mist' when cutting non-living objects. Also, even if the supernatural aspect would be blocked, it is still quite large, incredibly sharp, unbreakable/unbendable sword, so you would still get cut up, just differently.

But one ever use Well to fuel allomancy. And regarding TLM, that one sort of 'broke the rules' even in-universe, and they started draining it before it opened. It is feasible that removing the liquid (which you can do) makes it no longer kinetic, since it is no longer part of perpendicularity. Feasible. It is true that only Vin and Alendi heard it as far as we know, so it is possible that only 'the chosen' can hear it. There does not seem to be any mention that other Seekers at Alendi's time heard it.

Oh it is possible...if you wield Well of Ascension or something like that I mean, Larkin are not enough to do damage to Shardblade, Nightblood only chips Honorblade (and Honorblade and Shardblade block each other with no issue, so Honorblades don't seem to be more powerful in this way) despite vaporizing Thunderclast. Shardblades are completely different power level than anything appearing on Scadrial, Misting 'attacking' Shardblade would be like toddler attacking tiger.

I don't think Savantism would really help, it is not always (or even often) increase in power, and Shardblades are far too Invested to be affected to any dangerous degree. Per WoB Aluminum savant can clean their soul of impurities and such, but that sounds more like 'poison' healing, not straight up negating any damage to soul.

No, spike is not made. Intent has to be behind the actions, perception of the actions would be insufficient, because there is no intent there (capital or otherwise). Edit: The reason is that what is required to make viable spike is 3 things: 1) Spike 2) Victim 3) Intent . In the scenario you outlined there is only spike and victim, Intent is lacking. I am well aware that godmetal is physical Investiture, that is like half of my argument. But when burning godmetal, the power does come from the metal itself. Godemal is what directly fuels the power then, the entire ending of HoA literally hinged on this point when Seers burn away Atium to keep Ruin from getting his power back. If that was not the case, then Atium could not be used that way. Yes I do. One, ending of HoA would not make sense otherwise (wheter or not Atium there is alloy does not matter). Two, WoBs https://wob.coppermind.net/events/100/#e3658 , and WoB that Atium is directly the fuel (https://wob.coppermind.net/events/270/#e8028) Logically, this would then hold also for other godmetals and their alloys. Hence, if the Investiture of godmetal is coded with Identity, it will be inaccessible just like metalmind stores of another Feruchemist. And there is also this WoB on burning (Warbreaker spoilers) which basically confirms that Identity does play a role in whether or not Shardblades/Honorblades would be burnable.

Based on Secret History, Well was also perpendicularity, and we know that Stormlight can be heard once it is doing something. So perhaps holding perpendicularity open counts as 'work' so the Investiture in well is Kinetic.

Like I said, only examples of healing soul show that it uses more Investiture than Physical healing. Hence healing spike wound, even to a scar state, would take considerable amount, months at minimum. Yes, and non-lethal spikes don't grant anything, not yet at least. You cannot use it to steal powers even. Those people would plausibly require less healing, however you also need more volunteers for spiking and figure out how to turn it into usable spikes. Maybe, for one person. Because it is Honorblades and Medallions bestow their powers in the same way (https://wob.coppermind.net/events/331/#e9408) , and Honorblades cannot heal souls. Fabrials are completely different thing, they don't bestow power upon anyone, which is exactly why using them (e.g. Soulcasters) can be so dangerous. Fabrials have analogy on Scadrial in primer cubes, not Medallions. Elantrians are powerful if they have fuel continually supplied to them, without it, they are not much. And power of spikes does not lie in creating synthetic Metallic arts, but in the fact that Hemalurgy can be used to manipulate spiritweb in ways e.g. Bondsmith or Forgery can. Synthetic spikes would be insane power creep for any side that would know how to make them. You could hotwire your soul in basically any way, provided you had the knowledge. Why? Other Invested Arts are not anymore complicated. The Set, despite interrogating Marsh and so having access to all knowledge on Hemalurgy Spook had, were unable to make spikes created surviving victims work. I do not think it was a red herring, more in-world speculation that is wrong. And if they will be able to create them, I suspect they will either be far weaker, or there will be some limitations to them. Sanderson's magic is all about limitations and restrictions, and he does retcon things to keep things in line (Compounding with spikes being the most prominent example). So no, I don't think victimless spikes will be as simple as that line would suggest, if it will be even a thing. Yeah, that does not contradict what I was saying though. My point was, that Medallions are enough to ensure that powers are not lost once someone dies. If the Metalborn creates Medallion, that Medallion will continue to be available long after the Metalborn dies. That won't help for mainting southerners Magitech though. If Metalborn retains their power after creating Medallion, then they can create as many as they wish (barring material and time constraints). Passing the power down then becomes secondary. Passing the powers would be useful yes, but not necessary.

Notice the wording in WoB "If you were able to get a hold of that piece and burn it", the if clause includes burn it, so that does not preclude the Identity limitation I outlined. Except in this case the godmetal itself is coded to certain Identity, not just Investiture stored in the metal. And if Identity stops you from using burning to take advantage of foreign Investiture, then Identity of the godmetal should preclude you from burning it because it is the Investiture itself that is coded. Just like in metalmind where you simply cannot draw upon Investiture that is not coded to you. And burning godmetals does not draw Investiture from SR like you imply, but uses the physical Investiture directly, so that argument is flawed.

It is possible that minds simply cannot be created in such a way as to not be affected by being CS. Nature of mortals, lets say. Similarly how you cannot be immune to Savantism, it is simply a consequence of 'laws of realmatics'. Shards are not all powerful, so they could not make you immune to it, but they already shown great ability to affect mind, body and soul, so I think it should be well within their abilities. We did not see a persons broken body be healed by a Shard, and yet it is not impossible. Shards interfere directly very rarely, the most examples we have are from Era 1, and most are shortly after Shard changed hands. So it is not surprising we don't have examples.

There could be a complication, we know that metalminds and spikes are not burnable by anyone but their originator due to Identity (https://wob.coppermind.net/events/404/#e13536). And Stormlight spoilers

I think Shard could heal them, however it could be blocked by Intent. (e.g. Honor could not heal them because their madness was at least partially caused by oath-breaking, Cultivation did not see reason to heal them, or could not interfere for another reason). I mean, Shards can make planets, sentient and sapient species with souls, heal Savantism and most likely a lot of other stuff. I don't see why somehow this would be out of their powers. Perhaps the healing would be only temporary, but I think they most certainly could do it.

None of those specify how replicable it is. Can Bloodmaker do it? Yes, the powers allows for it. Will they have enough stored to do so? Since physical wounds seem to take less Investiture to heal than Spiritual ones, I think while Wayne could perhaps do it, he would do it once and deplete his entire metalmind. Remember that a lot of the more extreme feats shown by him in Era 2 are when he either had time to build up stores, or when he gets his hands on very full unkeyed goldmind, not every day situations. Huh, TIL. Though based on the WoB there is possibly something else going on too, since the two situations are 'different'. Still good to keep in mind. I don't think Honorblades would ever allow spiritual healing, even when their nebulous true power is unlocked. This WoB seems to suggest that the reason Honorblades don't heal is that the bond between Honorblade and wielder is 'shallow', compared to Radiant one. And since Duralumin is used in Medallions creation somehow, and Medallions have Identity of their own, I would wager that when using Medallion you also form a kind of bond with it. Theoretically you could perhaps create specialized Medallions that would allow Spiritual healing, but it might be semi-permanent bond, so they would not be usable just by anyone. Why not? Rashek moved them there specifically to preserve original genetic information, so it stands to reason he would want to preserve Terris as well. If he moved only those who he though were not Feruchemists (since he did not realize yet heredity of Feruchemy), there would be potential for Feruchemy in South. And since there would be weak potential for Allomancy as well, they would interfere together to produce Ferrings. And perhaps there were Ferrings before Terris did whatever it was that granted them full Feruchemy, similar to what Lerasium did for Allomancy. After all, Terris had to have some motivation or idea that certain experimentation could yield Invested Art, otherwise it is quite odd. It seems to me much more natural explanation that there were occasional Ferring in South even prior to Kelsier's coming, than that every single Southern Ferring is either produced through Hemalurgy, or offspring of someone who was, since we know that Hemalurgy has some consequences for reproduction.

The WoB was about Miles being able to heal spike damage, and the answer was that he would need a lot of investiture to do that, and if he did not have enough he would be left with scar on soul. It is the most applicable statement we have. We can also compare how much Stormlight Radiants consume to heal physical damage, and how much they consume to heal Spiritual damage. And they consume a lot more for Shardblade wounds. Good point on healing the arm, all I can say is that perhaps healing deadly Shardblade wound (and so deadly Hemalurgy) is what is beyond Regrowth unless fast enough. And he was not fully dead, his soul did not leave for Beyond, even Nale acknowledges that he was lucky to get there fast enough. Why? In Medallions seem to be closer to Honorblades, granting their wielder the ability to use Invested Art semi-directly. Analogy being that what Honorblades are to Surgebinding, Medallions are to Ferrings/Mistings. Fabrials would be more akin to Primer cubes I would say. Yeah, but where are any others? There is no hint of them in SoTD for example. SoScads were placed there by Rashek as control so that he could undo the modifications he did to people when Ascended. So it stands to reason he would have placed there 'examples' from various peoples, including his own. And on top of that there is WoB that Southerns have seed of all Metallic arts in them. (https://wob.coppermind.net/events/243/#e6148) Yes, and creating Medallions is sufficient to ensure the powers are continually available. Once you have Brass Medallions, you are set. And to have enough Medallions for populace, they must be able to replicate powers somehow, otherwise you would never have enough Medallions (if one Medallion = One dead/powerless Ferring). Well all of that is planned for Era 3, Era 2 was a 'side-story' so to speak. Well Hemalurgy is not the answer, for the simple reason of diminishing returns, and inability to replicate powers, only transfer them. I suspect the answer will be some application of Nicrosil, Duralumin and Harmonium. And yes, perhaps some Hemalurgy to kickstart the process.

Because per WoB it would be a lot even for Compounder like Miles. Miles can get month worth of storing in days, if not in shorter time. If it was months, Wayne could heal that, and Wayne is quite outside of Miles' league when it comes to healing potential. So it should be years worth of storage, if not decades. If it is difficult for Compounder to get enough, it is nearly impossible for regular Ferring to pull off. Secret Project 1 spoilers Most are though quite certain it would take two things Healing soul/spiritweb. A lot of Investiture. Medallions alone cannot provide 2), and I strongly dispute they allow 1) based on example of Honorblades, and every other example of external healing. That was retconned, so far Regrowth fabrial was never used to heal Shardblade wound. Only things that were shown able to heal Shardblade wounds were innate Invested healing abilities, i.e. being Squire or Radiant or Fused. Fabrials are not enough, Honorblades are not enough, external healing via Radiant is not enough. I don't see any reason why Medallions should be different in this regard. No, we know per WoBs that Southerns were unmodified pre-Ascension population. So they had potential for Feruchemy, and also low potential for Allomancy. It was weak enough that Full Feruchemists and Mistborn would not appear, but occasional Misting or Ferring would. And since Feruchemy used to be the more common of the two (prior to introduction of Lerasium Mistborn to gene pool), Southerns probably have more Ferrings then Mistings. Yes, and we know they are being worshiped and revered, neither of which is suggestive of ritual murder. Fair. We don't know how involved Kelsier was with that. Notably, considering his outlook in TLM, why would he hide such a powerful artifact, instead of having him on hand for his Ghostbloods to use in emergency? There are things around BoM that don't really make much sense, and while Kelsier was apparently involved in their creation (though more recent WoBs RAFO this), we don't know to what extent.

Yeah, it would let you let you get required Investiture about 3x times faster (8 hour shifts). But that does not change the fact that the raw amount of Healing required is still on order of years, so you would still need to wait years before single Medallion could heal anyone with spiked out power (if even possible). We don't see fully powered Elantrians rampaging across Cosmere, and they are restricted in different ways. I think Hemalurgy will play important role in future, but not as something that is comodified. Can they? Do we have some examples? Because I cannot think of any. No, Regrowth is always less potent than internal healing (https://wob.coppermind.net/events/451/#e14448). Even healing someone harmed with Hemalurgy might not be possible with Regrowth. (https://wob.coppermind.net/events/171/#e8579). And Honorblades cannot heal soul (https://wob.coppermind.net/events/116/#e4788) and Medallions function in similar way to Honorblades in that they are both external tool that allows wielder to access Invested Art, and both have some Cognitive/Spiritual Aspect of their own (https://wob.coppermind.net/events/509/#e15930 and https://wob.coppermind.net/events/508/#e15901 ) So far all the evidence seems to be that external healing methods are strictly weaker than similar internal methods, and that using Invested power that is not native to your spiritweb means it is less potent, especially when it comes to healing. I don't think that would be possible, since I don't think Medallion lets you heal spiritweb at all. It simply is not possible. Healing only to extent of Spiritual scars would simply be result of not having enough Investiture, as other WoBs specify. No, they were there, just rare. Otherwise there would be no one Kelsier could teach how to use powers. And Kelsier got to South very shortly after Catecedre, so it is doubtful that by then Spook would have figured out Hemalurgy.

Not at the same time, that is the key constraint here. Multiple can use Medallions yes, but not at the same time. One person, One Medallion. That would be interesting. Question is, would it be economical? But a smart work around nonetheless. Those would be interesting, if they will ever become viable. Personally, I think that fully synthetic spikes will never become a thing, for two reasons In-world: It goes against the Intent of the Shard associated with Hemalurgy. The means of accessing Invested Arts are typically linked to given Shards Intent (Bonds/Oaths for Surgebinding, Giving for Awakening, etc. ). Hemalurgy is tied with Ruin, hence to access it requires Ruin. Out-world: Fully synthetic spikes would lead to gigantic power-creep, which is something Brandon is clearly avoiding (see restrictions of spikes and Compounding introduced in TLM). Maybe you could hack it somehow together, but I think it would end up far less powerful. But as I mentioned, we see in SA that healing that does not come directly from the person is less powerful. Honorblades, Regrowth, all those are less powerful than natural healing of Surgebinders, and is explicitly not powerful enough to allow healing of spiritweb. In Medallions, the source of healing is against external to the person, just like when using Honorblade, and so it stands to reason that Gold Medallion simply would not be capable of healing spiritweb damage. Sure, if all you want is to spike out power and give it someone else, then yeah, Medallion could keep them alive, but they would still be spiritually damaged like Drabs (but worse). Donating a kidney won't diminish your quality of life in every single way, which is what surviving spiking apparently entails. Spiking survivor is in certain sense, less 'alive' then before. Very few would volunteer to be depressed for rest of their life, to get ill more easily, to have their thinking compromised, etc. I don't think they are. They revere Metalborn, that speaks against, well, killing them for their powers. Remember that spiking without killing was news even to Kelsier, so Southerns are certainly not practicing it. Medallion production apparently does not necessarily require Hemalurgy though.

The first one.
