Thanks! I tried but failed to search for WoB. That makes sense, though still leaves completly open why did Vasher run away and Vivenna is chasing him

So in RoW Kaladin duels Zahel, who uses Awakening to Awaken sheets and use them in a fight. Notably though, he never makes audible Commands during the entire fight. Which means he must have been Awakening mentally, which means he must be of 10th Heightening at minimum, and so must have 50 000+ Breathes. Which raises question, where did he get them?. Did he steal Peacegivers Treasure? Is that why Azure is after him?

Not actually true, one Lerasium is never seen being pushed or pulled on (as afar as i know), and atium was retconned to be atium-electrum alloy, which would explain why it can be pushed/pulled (similar to why duralumin can be, despite being ~90% aluminum). No, godmetals are the most dense form of Investiture. Gas < liquid < solid. What makes you think other godmetals are not as Invested? Awakened items don't seem to be more difficult to damage, not unless the command somehow specifies it. Could be misremembering Warbreaker, but nothing there suggest awakened items are more sturdy. Kaladin notes that some still writhe on the ground as if in wind, so either they retain breath, or Shardblade completely destroyed breathes that were awakening the items. Or Vasher was cleaning up after himself in the middle of the fight, and had timing precise enough to take Breath back the moment item got destroyed. Also, technically the fight shows that somehow Vasher must be of 10th Heightening, because he awakened the sheets without audible command. So he must have 50 000+ breaths. Did he steal Peacegivers Treasure? Is that why Azure is after him? Ah, makes sense.

The only Atium post-Catecedre was with Marsh, so Atium is not the answer for Spook. TLM spoilers

Remember that limbs cut by Shardblade also turn grey, so that is not specific to Vivenna blade. If anything, I would say that absence of burned out eyes suggests less damage than what Shardblades does. Fused also typically avoid Shardblades, and in Oathbringer Fused were still relatively rare, so they would not wish to suffer unneeded losses. I doubt that Vivennas blade can kill Fused permanently, after such big deal is made of Nightblood being capable of killing them permanently. If Fused knew that they can be killed permanently by Vivennas blade, then surely Raboniel would make mention of it, since it would be second sword that could do that, so clearly replicable. But if only Nightblood can do it, and Nightblood is special, then alternative means (like anti-light) are needed). Also, I mean that Vivennas blade does not consume Investiture from wielder. Honorblades and Shardblades are not Invested with neither Stormlight nor Lifelight. They are both Godmetal and that is that, made of Investiture (https://wob.coppermind.net/events/6/#e247). While I expect there to be some differences between Orders, per WoB we can treat all Shardblades as same alloy (https://wob.coppermind.net/events/372/#e11949). That is factually not true. Metalminds are not harder to damage, Awakened items are not harder to damage (unless specifically Awakened with that Intent, and there are limits due to physical properties), fabrials are not harder to damage, etc. And again, you cannot have uninvited Tanavastium, since Tanavastium is Investiture. That is like asking for dry water. Shardblade/Honorblade being unbreakable has to do with their nature as singular entity, and also with the nature of Godmetal I think. That is roughly how I was imaging it yes. Though notably, it requires a lot of Investiture before objects start resisting meaningfully, as seen from duel of Vasher and Kaladin. Again, as stated before, Shardplate is about as Invested as Shardblade, see WoB (https://wob.coppermind.net/events/217/#e7299). The reason it then takes damage must have to do with something else then relative Investiture levels. (or not just that). Clearly not the case, e.g. Invested sheets being cut trivially. So metalmind must contain some amount of Investiture before it start resisting being cut in any way, and much more than that before it starts blocking Shardblade. Notably, Bands of Mourning, the most Invested artifact on Scadrial, is not Invested enough to be considered 'Shardblade' in general sense (https://wob.coppermind.net/events/13/#e4878). Ah, good point. I did not think of it, as it is such a different level from Shardplate honestly Thanks for correction. Yeah, but if as seen from the video, you can penetrate the armor without need to directly strike the individual chains (simply break them with blunt force, not cutting force), then chainmail cannot protect wearer very well against strikes from Shardblade, since you can shapeshift them into a large war hammer with long shard spikes. Rosharan Shardblades also turn body parts gray when they cut them. Only when severing the spine/brain do the eyes burn out, which frankly sounds like more damage then simply turning grey. Eyes being the windows to soul and what not. Also, Rosharan Shardblades do cut on all 3 realms, so no Vivennas blade is not more powerful than Shardblade. The spheres could still hold Stormlight just badly, as per WoB you quoted, so not that useful against Radiants. And if the Radiant had spheres within Plate, Awakener could not touch those. And in Urithiru: SA5 spoilers

So, in TLM we see that Dor can be stored in jars and is in possession of Ghostbloods. Similarly, in RoW, in Lasting Integrity Stormlight is held both in perfect gems and also in large jar that was bought from Ire. Few notes: By the time of RoW, Ghostbloods seemingly don't know that Investiture can be stored in jars like those seen in Lasting Integrity and TLM. The reason is that Ghostbloods are trying to get their hands on perfect gemstones to transport Investiture, which makes no sense if they had access to those jars. Since Shallan reported to Mraize that Honorspren had the jar, and that they bought it from 'Eyree', it is possible that that was the moment Ghostbloods learned of this. This can possibly mean that Ghostbloods simply bought purified Dor from Ire, which would explain why it is treated as so rare a thing Also, in RoW Navani notes that Stormlight is not gas, but has elements of both gas and liquid. Possibly then, purified Dor is not as different from blanked Light as it can seem at first glance. But question is, what are the jars made out of? They don't seem to be a fabrial of some kind, but I doubt they would be ordinary glass.

At that point the rock is basically a cannonball, it could feasibly tear through chainmail, unless that chainmail is magically enhanced with greater structural Integrity. Remember that chainmail is good against slashing , not against blunt force. It is made of small pieces of steel, that would give way more easily under such force. Miles would still care, because one hit with Shardhammer (wielded by someone in Shardplate) would still crush his internal organs and break bones/spine with a single hit, because chainmail is flexible. Even Miles would take 1-2 seconds to heal from that, and he was F-Gold savant. Point is not blunt force trauma, point is that shardhammer would tear up the chainmail, and make in ineffective. Yes, it would stop the one-shot potential of Shardblade, that much I agree with. From regular hammer strikes chainmail won't break most likely, but then again, neither will Shardplate. From hammer strikes that are ~6-10x the size of regular warhammers, and wielded by someone with superstrenght? Chainmail will break. And even if not, a single hit would still completely crush organs and break bones of the wearer, because of the flexibility. Kaladin lashed himself as many times as he could, which could be just 4x which would be inconsistent, but it could also be 50x which would be consistent. Basically, since we don't know exactly how many times he lashed himself, it is as consistent as Brandon wants. I don't think Plate has been made weaker, it was just out of focus for a moment, as we were exploring Radiants before 4th Oath. Now that Kaladin has Plate, I expect we will see more of it again. We still basically never see anyone in Plate get killed without Shardbladed opponent. Sidenote: I wonder how feasible is to use chainmail as metalmind, since it is made up of small links and is not a large continuous chunk of metal. In theory the metal could have been Invested first, and then forged into chainmail, but would it work as small metalminds (if it retained appropriate ratio of metals). For Awakening this won't be an issue, as it ordinarily takes over more complicated objects. Sidenote 2: Why did the Five Scholars not create Awakened armor? When they visited Roshar, Plate was already in existence, so they would have known about it. So why create only the weapon, and not the defensive (and arguably more useful) tool? Edit: WoB confirms Zahel does not know how to Awaken with Stormlight, so the sheets were Awakened using Breaths

Based on what is said in Ars Arcanum it sounds to me like the opposite. In that Compounding with Hemalurgy worked only because Ruin was actively pushing to make it work, and on its own it won't. Similarly, the ability to gain many powers, hemalurgic decay etc. were result of Ruin actively pushing on and trying to leverage Hemalurgy more. I.e. current Hemalurgy is 'how it is supposed to be', and Era 1 Hemalurgy was supercharged version. Relevant Paragraph:

I honestly don't know. It depends on what exactly happens when Shardblade is blocked by Invested item. I would wager it either losses some Breathes per hit, or it loses some 'idealness', which eventually causes it to catastrophically fail (e.g. shatter) and it is during that Breathes get destroyed. In some sense yes, it is more brittle then weak. But I would say it is still stronger material than tempered steel. Again, Shardplate can take a hit from ~5 kg of rock flung at ~100 km/h without virtually any damage. Do that to steel chainmail and it gets torn through. Shardplate is basically supernatural cast iron, but basically all its properties are above those of regular metals. Invested steel will still be only steel (unless some Command helps enhance its properties). Doubtful. It might rival it in some aspects (since you can replicate a lot of Invested arts using a different one), but it would not surpass not, not by great margin. Per Brandon, Shardplate is 'powered armor' of Cosmere and There is one WoB saying plate would resist bullets well (https://wob.coppermind.net/events/100/#e3561), and another saying that Wax with specific weapon, in the right moment, with the right bullet might break section with 2-3 bullets. And Wax as Crasher can put a lot of weight behind his Pushes (and uses it to enhance power of his shots to make them penetrate barriers they would not otherwise), so it is entirely possible that Wax can do it...if he uses up years worth of weight in a single Push. Possible in principle, but exactly reliable. Roseite Aether can resist bullets easily, and is seemingly both more brittle and less strong then Shardplate metal. Shardhammers can break through plate after dozens of hits (or more), and is wielded by someone in Shardplate (so someone who is ~15x as strong as human). And they are so heavy that 2-3 people have to carry them. Shardhammer would absolutely destroy any chainmail, or the person wearing it, since flexibility of it would work against the defensive goal here. The material plays a role only when it comes to the regular cutting/defense potential. But against Shardblade that does not matter, only the Investiture content matters. I don't look past it, Shardplate is basically impervious to non-Shardblade attacks. Look at what Sadeas took, bunch of warform parshendi wailing on him with hammers for minutes and they did not break a section. If he had plate or chain mail, he would be dead within seconds. Shardplate is vastly stronger material than regular materials. Plate shields from Blade regardless of having Stormlight in gems. Stormlight is only necessary to heal Plate (and allow movement in deadplate). No difference in how light spills out, only it takes a lot more to damage Plate when using anything but Shardblade. Most likely, depends on Command, number of Breathes, and maybe other conditions. Not sure honestly. One, Awakening Atium blade would be probably difficult (Investiture resists Investiture). Two, Atium is soft and pliable, so it would not make good sword, but perhaps that can be improved through awakening. I think there is another question here: What properties of Shardplate/blade are result of being Investiture/heavily Invested and what are 'natural' properties of the Godmetal alloys that make them up?

No need to apologize,it makes sense Good question, dont know Based on this WoB (https://wob.coppermind.net/events/379/#e12667) Awakening with Stormlight is plausible, though it seems to basically require changing Stormlight into Breathes. But this newer WoB (https://wob.coppermind.net/events/475/#e15045) states they did not yet crack how to change one Investiture into another, so Zahel cannot do that. So I think he used Breathes. On whether he was able to recover some Breaths after cloth was cut, I would expect that yes, though less then he used to Awaken it. We know that recovering Breathes from damaged or destroyed Awakened items can result in loss (https://wob.coppermind.net/events/202/#e5957), and I would expect that Shardblade would among the more destructive ways (considering it damages more comprehensively then mere physical damage). (Also we have this WoB (https://wob.coppermind.net/events/358/#e10748) that answers whether Awakened cloth could resist Shardblade.) I don't think that is the case, simply because Shardblade only differentiates living vs non-living objects. It cuts cloth basically as easily as it cuts metal. So more Invested cloth would resist Shardblade better then less Invested metalmind, physical composition of object basically does not matter to Shardblade (aluminum being the sole exception). I don't think that is the case. As we see from Notum, hurt spren require Stormlight to heal, they don't just draw it from anywhere. Simpler explanation is that the Godmetal alloy Shardblades are made out of is simply incredibly strong metal (e.g. unbreakable, as is fitting for Honor's alloy), and the possibility of breaking Plate is due to it being composed of multiple spren (who have to 'bond' so to speak). So when Shardblades clash, neither actually damages the other, or only in very minor ways (effectively 'scratches'). Investiture wise or Cognition wise? Because Investiture wise I would put it like this: Nightblood >>>>>>>>>Honorblades>=Shardblades>Vivennas Blade. Cognitive wise, I think Vivennas blade is a bit more concious then Honorblades, but less then Shardblades and Nightblood (though maybe it is just shy ) Nightblood is special case, and Vivennas blade does not seem to consume Investiture. We know too little about Type 4 entities to make sweeping statements about them. The best example we have is also an outlier. I don't think you pull any Investiture from spiritual realm in such way. Yes, both of those swords have spitiweb in SR, but that does not mean they draw upon Investiture, just that they are alive. But I do agree that Type 4 entities being alive is the reason why Breathes cannot be retrieved, since they are now keyed to Identity of the created Type 4 entity. Same reason why Mistborn could not burn Nightblood (https://wob.coppermind.net/events/85/#e2901), and possibly also Shardblades. As stated above, he most likely could not Awaken with Stormlight. And I think Vasher does not care much, since he has guaranteed 5th Heightening from Divine breath, and is feeding on Stormlight to survive. If he used ~100 Breaths in that fight, and lost even half, that is relatively ok amount for him. Physical mass lets you hit with more force, so that part tracks. But I don't think it would make any appreciable difference in how many strikes can metalmind take, the difference is too small, because the chainmail is still the item that takes brunt of the damage.

Aluminum negates the Invested power cutting itself, Invested item just matches 'strength' against 'strength'. So instead of just physical strength of material, it is also spiritual or Invested strength that gets matched. The WoB does not say the straw man would block the Shardblade, only 'block to some extant', i.e. resist And considering Lifeless would act like living being, I would wager that straw man with single breath would get cut just as easily as anything basically not Invested. If you dump couple thousand Breaths in straw man, then it would resist better. Additionally, we see Shardblade cut through Invested cloth in RoW, in the duel of Vasher and Kaladin (where we know Vasher used Awakening), and it does not seem that it offers really any noticeable resistance, Quotes (note that Sylblade is dull for most of the fight, and only becomes sharp when mentioned): So at minimum we can say that anything Invested with 1-10 breaths won't offer meaningful resistance to Shardblade, and it would probably take high-hundreds, low thousands before any effect (even minor) would appear. Heavily Invested metalminds can block Shardblade, any metalmind won't do. As we see from Awekening example, you will need quite a bit of Investiture before anything noticable starts happening. Wax's and Wayne's metalminds would most likely get cut quite easily. BoM would block some blows, but how many? Ehm, it takes much more force for a rock to crack a section to any noticable degree. The one time we did see rock crack Shardplate, it was rock size of human head (so several kg's), thrown from a sling by Warform (who are stronger than humans, so the rock is moving up to ~150 km/h), and all it did was puff a little. Compare to Shardblade, where a hit noticeably and considerably cracks a section, which then leaks for a while. Also, steel would deform and break under the sort of attacks that Shardplate regularly withstands, so while it breaks differently, I would not say it is more brittle then steel. It is considerably different in how they respond. You won't break a section of plate (or half-shard) with 2-3 strikes from any ordinary melee weapon, even when wielded by someone with supernatural strength. (up to a point of course). No. As said in the WoB (https://wob.coppermind.net/events/100/#e3353) the Royal Locks just count as living unlike regular hair. So they will get cut just as easily as human. Most likely yes (as seen from Kaladin and Vasher duel), unless Invested enough (e.g. hundreds maybe thousands of Breaths). Not leeched, damaged/destroyed. As seen in duel in RoW, Awakened cloth offers basically no resistance to Shardblade. Metalminds have also never been attacked with Shardblade, so we don't know how they will behave. But based on WoBs, they will get broken after some hits, and I suspect broken in this context means that the Investiture in them will be destroyed or rendered unusable. That is not what I am suggesting. I think that the spiritual ideal of the item gets damaged, and as a result the object degrades. In the context of plate, degrades = cracks, and then starts leaking Stormlight through those cracks. In the context of half-shard, degrades = the fabrial gets damaged. In the context of metalmind, degrades = ??, but possibly at minimum the structural integrity would lessen? Or the Investiture in the metalmind gets a bit lessened (since Shardblade cuts on all three Realms (https://wob.coppermind.net/events/100/#e3560) it must have ability to destroy Investiture). We don't, but we do have the duel in RoW. Straw man would 'block to some extant', and the WoB does not specify how many breaths the straw man would have. And the duel shows that couple of Breaths won't offer any meaningful resistance to Shardblade. As seen from the duel in RoW, not really. Kaladin did not even use Surges in that fight, but Awakened items were getting destroyed by Shardblade easily. Aluminum has poor properties to make chainmail out of. Pure aluminum (which is the relevant material) is quite soft and weak metal (it has smaller yield strength than plastic, polypropylen), so it would get easily deformed/torn by Shardblade. Some alloy would be better, but it would have worse defensive properties against the Invested cutting part. Good question, I don't know. Though Nightblood did chip Honorblade, so it is not inviolable. I would wager that to damage Shardblade you have to remove considerable amount of Investiture from it/it's spiritweb, and regular clashes are simply not enough. As you say, Nightblood now holds faar more Investiture then 1000 breaths (plus Shard was involved in its creation), so he is not good example of anything really. Vivenna's blade would be better example, but we don't know how exactly it was created, and we have never seen it clash with Shardblade, so it is possible it would get chipped. Since Honorblade got only chipped when cut Nightblood, both Shardblades and Honorblades must be ridiculously Invested, or have some other means of staying whole, since Nightblood outright vaporizes everything else. Additionally, those are not merely Invested items, but more akin to artificial spren (https://wob.coppermind.net/events/100/#e3586), so they would behave differently most likely. Also, Shardplate is not 'far far far' less Invested then Shardblade, they are comparable. So the reason Plate cracks and Blades don't is probably related to the fact that Plate is formed from multiple spren, and not single spren. One, Shardplate is not Invested metal, it is Investiture in metallic form. Two, its resistance is not due to holding Stormlight. Three, as seen from RoW duel, sticky Investiture (Breaths being the most sticky we have seen so far) does not really offer meaningful resistance, and there is no reason to believe it would offer better protection. Based on the examples above, clearly when in WoB we see resistance or blocks to some extant it simply means that cutting the object would not be as effortless as usual, and if Invested enough (i.e. on level of ~half-full metalmind) it will start to actually block Shardblade strikes, but it will break after few (1-2) hits.

I don't think that is it. One, in half-shard the fabrial is one the opposite side, so is completely shielded by the actual material of the shield, and even then non-plated Shardblade wielder can break them in two blows. Two, Shardplate section can withstand minutes of superahuman blows from multiple assailants, will withstand bullets well, and yet 2-3 hits from Shardblade brake a section, even when opponent does not have Shardplate. In both scenarios the material breaks despite the supernatural cutting being negated through material being Invested (and in the second case Shardplate is far harder than most metals and is also much more Invested than any metalmind), but it still breaks far faster then when attacked by non-Shardblade. So clearly, being Invested is insufficient protection against Shardblade. So something else must be going on. Since Shardblade cuts on all 3 realms, I would wager that even though the Investiture in the objects prevents it from being penetrated by Shardblade, the hit still damages it on cognitive and spiritual Realms. I.e. the Investiture/spiritweb of the objects gets damaged. And we only have WoBs that Invested objects resist being cut, not that they are immune to being cut. So I would conclude that somehow Shardblade damages the Spiritual aspect of the metalmind, and so degrades (not leeches) the Investiture within it. You can still use it to block, but I bet it will get damaged and it would eventually fail. Edit: And this WoB literally says that metalmind will break after repeated hits from Shardblade

Oh, Fullborn could heal cut from Shardblade, I was just disputing that F-gold is more efficient than Stormlight healing for soul wounds. We have zero evidence to say so, and some WoBs hinting the opposite, that Stormlight healing is more spiritual based and so more efficient in that regard. Full metalmind is said to be 'middle of the realm', comparable to half-shard, and those can block Shardblade for one or two hits. So Shardblade does damage to heavily invested items, so question is, how will that interact with metalminds? Edit: (accidentally posted before finishing) Yeah, but that is 'just' regular damage, Radiant could possibly heal like that as well (if they had enough Stormlight). Key here is that if Shardblade severs spine/head and so removes severs Fullborns link to his body, Fullborn is left without access to Investiture and so cannot heal at all. The second option won't work, you cannot push/pull objects outside of speed bubbles. (they interfere with Investiture). The first option still won't work, since F-Iron conserves momentum (you slow down when tapping, speed up when storing), so you get exactly one push on the anchor, and if you try to recall it back, you lose all the momentum you gained that way (and you would end up right where you started when the anchor gets back to original position). Basically, you can push on the anchor, but you cannot pull it back, else all the movement is undone. So the first option lets you move like a yo-yo around central point, back and forth, but will not get you any net movement (unless you just push away and lose the anchor).

I think it is human bind points in general, but it only shows those that would be possibly relevant in creation of Steel Inquisitor. You don't have to use all of them, but any combination of them (though minimum is probably 8 + lynchpin) can be used. Why would you say that such spikes don't warp you into Hemalurgic monstrosity? I don't see any reason for that. Why are you saying other metals have little impact in savantism? We know actual 'full' impact of only 3 metals (Tin, Pewter, Bronze) and have no information on the other. The impacts can be more on cognitive side of things for example, or such that within Scadrial 'Investiture-poor' ecology they won't get noticed (e.g. Bronze savant might have weakened life-sense compared to baseline humans, but they won't really notice because it is subconsious anyway). To generalize that non-physical metals have little impact is a bold statement.

Probably not, Hemalurgy takes only relatively small portions of the spiritweb, with some left over Identity and Connection. However, even when you spike yourself, you still remain yourself with all of your Identity and Connections, with the Hemalurgic bit allowing you only small things (e.g. use metalminds of donor Feruchemist), and not much else (e.g. you won't suddenly be able to speak Terris, or start acting a bit like that person). And since Forgery is extremely reliant on precise knowledge of the object/person you want to stamp (see Emperor's soul and how long it takes to prepare soulstamp for a person), I don't think you could use the stamp on yourself, the spiritweb is too different. Basically, unless you somehow replace your entire spiritweb (at which point you would cease to be you) you would not be able to use such Soulstamp. However, there are now Universal soulstamps (though seemingly only for objects at the moment), so if there is a sliding scale of 'universality' of soulstamp, then perhaps some soulstamps that were intended for specific person, but high enough on universality scale could be used by someone with a spike.

If it was latent benefit, they would notice it while not holding Stormlight, which they don't. The feats appear only after breathing in Stormlight, which is kinetic Investiture. Additionally, both Elantrians and Returned require Investiture to remain functions (AonDor in Elantrian case, regular supply of breaths or other source for Returned), so they don't have just passive effects. High Heigthenings are the only fully passive effect, and those don't grant neither healing nor strength, though they do get immunity to most toxins and illnesses. It appears that there can be similarities, as Riino originally thought Kaladin attained Heightenings (but was not specific about it), before realizing he is Surgebinder. Passively though, Surgebinders are still regular humans, just their spiritweb started merging with spiritweb of Spren. So if we consider them to be fully merged, the effect would be somewhere below First Heightening I think, at most 2nd. So they don't really have that much Investiture by themselves, see this WoB

I think some game breaking things won't be possible due to intentional restriction on Brandon end. E.g. TLM spoilers I don't think you could fit that much charge into single Hemalurgic spike. They contain (or serve as conduit for) parts of spiritweb, which are just Investiture and quite a bit of it. Even if you could, I think you would end up with some sort of Hemalurgic construct/monster, because at the end of the day you are still spiking in ~100 people's worths of spiritweb fragments to single spiritweb. And finally, you can never fully store an Attribute, so there will always (at least within scope of Feruchemy alone) be some left-over Identity. There is a floor to storing. So I think it would have to be with single donor who would have to heal all the damage done.

Funny thing, Brandon actually RAFO'ed this question But apparently it is not hard to figure out, so we might try. Cosmere spoilers

To me it feels a bit low, but you did great job of sourcing your hypothesis and it seems a reasonable estimate. Only thing I would adjust would be that clergy should be included in the number of nobles (as they were sourced from them), so that would increase it from 3% to ~10% (taking average). However, as you state, in fully enslaved society the ratio could be different, and since Skaa were of lower intelligence and more docile early on, this would bring the percentage back down. But, not all were Skaa, as TLR was conquering other societies. So I would probably go for something like ~5% noble population? That would raise the numbers a bit, but no by that much, to something like ~132 Mistborn being sort of soft statistical cap. Still though, Mistborn would be much more rare than I thought! ~1:100 000! Which feels too low.

I doubt that for simple reason, Kelsier is Cognitive shadow made of Harmonies (or maybe Preservation's ) Investiture primarily. So the Investiture that is making him up is Connected to Scadrian system. So to do what you suggest is to suggest he basically completly remakes his soul. I doubt he could even spike himself with Trellium spike, since it would be repulsed from him.

Kaladin could not have used surge in that instance, as the suppressor fabrial was on. The only surge he could use was Adhesion, and that would just glue his hand to Fused, not hold him back. And in that section of RoW every single usage of Surge is described to us, because it is plot relevant (to understand how suppressor fabrial works). Edit: Reverse lashing would also not help, since it would draw Fused towards Kaladin, something he was trying to stop in that instance. This is pretty much as clear cut as it can get that Stormlight does enhance strength. Stormform are far stronger than humans, and yet Kaladin + Stormlight could hold him back and grapple. Stormform was still stronger, but not as far as 2-3x, because then Kaladin could not do what he did. https://en.wikipedia.org/wiki/Hysterical_strength feel free to browse. Arguments are that due to weight distribution, they are lifting just something around several hundred kg's not tons. Still more then they could do in ordinary situations (and the people are not trained worldclass deadlifters). And Stormlight could probably let you push even further, since it heals the damage done. Ultimately though, hysterical strength was more of a illustration example, not a statement on limitations. Those two situations are definitely something else going on, and it was even directly stated by Brandon, and I acknowledge that above.

F-Gold has also never encountered Shardblade, or really had to heal anything but ordinary physical damage. So I would say it is a bit early to say such thing for certain. And healing Shardblade wounds with Stormlight is not difficult? Mere 3rd Oath Radiant can easily do it. That is again external healing applied upon someone. Also, there are differences between the two situations per WoB The problem is still the same, all that Investiture is coming from their physical body, they need either metalminds to tap, or metal in body to burn. If the connection to body is severed, Fullborn has no more access to Investiture, and no more Investiture.

I don't think that the people Ruin would kill per the original deal between Ruin and Preservation would consider that cooperation 'harmonious'. They can work together to create, but the cost is that they must then also let it be destroyed/destroy it.

As @Frustration said, Bondsmith can increase that rate as well. But that is besides the point, as the only reason to do that is possibly buy time to get to CR, where Bondsmith is safe and can manipulate Fullborn at leisure.

Yeah, those are beyond what is reasonable. Shardbow requires Plate, so at minimum something like 15x strength, and the rock Dalinar was lifting was something like a few tons or around that (someone did some math once). Interestingly though, the 'adrenalin'-like effect then puts Radiant with Stormlight near A-Pewter who is not flaring, or possibly even one who is. IRL incidents are of people lifting ~1-1.5 tons at extreme ends, which is definitely in the ballpark of 3x strength. A-pewter would still peak higher though, since they can get adrenaline rush on top of A-pewter.
