Ishar is likely messing with their Connection to CR and PR, but that should not change their Connection to Roshar - that's something different. Spren have bodies in CR, those killed by Ishar had the same bodies in PR, so those bodies were moved between realms. Their Connection to Roshar is because they are saturated with investiture of Honor and Cultivation and that binds them to the system. No matter if they are in PR or CR, they are still bound by this. You need to manipulate this specific Connection to Roshar, which Ishar likely wasn't touching at all as that wouldn't help him manifest bodies of spren.

I was going to write that spikes aren't part of their body, so they should not decrease in weight but then I looked at this WoB which I had in mind: So spikes can't be pushed because of their proximity to the soul, but that also makes them a part of PR. So maybe? It makes sense their mass would be affected by F-Iron if they really are considered as a part of the Hemalurgist body. Edit: Per this WoB they also have this proximity to the soul so they should count as well.

It's because you don't find and get Ryshadium, you are chosen by them. Most won't be that lucky. WoR ch 81: Historically speaking horses weren't really used for fighting on Roshar. They are especially expensive, require special care and aren't well adapted to the Rosharan environment. The first nation to use cavalry as a fighting formation was Shinovar during their numerous invasions of Roshar, which most likely happened after Recreance, thus after the Radiant era. Therefore most Radiant would not use horses like the classical medieval knights. Even now cavalry is still very rare because of how rare and expensive horses are. In WoR ch 67 Dalinar remarks that loosing on a plateau run could easily cost more than what won gemstone would be worth. I'm uncertain how useful Ryshadium would be for most Orders. Two of them can fly, so horses for them would be pointless and other Radiants would be Lashed by them to arrive quickly to their destination - as seen in the Starfalls vision. On a battlefield their horses would be extremely vulnerable and could expose their rider to enemy strikes when killed.. Moreover Surges are a devastating weapon to wield - Jasnah soulcasted air all around her into oil and set it on fire, which would kill her horse. Unless they somehow get a Shardplate for their horses (which should exist after Recreance if that was practiced, the lack of such horse Shardplates implies it wasn't), Radiants should not bring horses to a Surge-fight. Adolin learned this lesson the hard way. So while Ryshadium are called a Third Shard, I wouldn't necessarily assume that they were called that during the Radiant era. For me it seems like a modern development, rather than something carried from ancient times. I think spren fill the role of "a knight's horse" - it's not just about riding on a horse, it's about companionship, that's what spren are to their knights. And Kaladin hates horses. He would rather ride on a Chull than on a horse. Imagine, a graceful knight in a glowing full plate riding on an oversized crab.

Savanthood is a bit different. You become a Savant because you were using your powers for so long that it warped your soul to match the power, which often have some very drastic consequences to your body - Kaza from OB interlude 4 or Ithi from OB ch 81 are Soulcaster Savants. Soulcaster Savants' bodies change to match the substance they're Soulcasting things into - Kaza is turning into smoke while Ithi is turning into grain. But to have those effects you have you use your powers for a long time. Both Kaladin and Shallan barely started using their powers, they aren't Savants yet. It takes years to become a Savant. But Radiant suffer less from Savanthood - they don't turn into smoke for example. Moreover Brandon is a bit careful with making people Savants left and right - the idea of Savanthood is that the power warps your soul and it has some harmful consequences, it's not just a power boost, it's something important to their story. I highly doubt he would have made both Shallan and Kaladin into Savants (which also isn't very obvious). I think Windrunners in general can lend their Shardplate to protect others, which just fit with their order. But I find it likely that all orders can do that, it depends on the level of control they have over their plates. You were talking about extra powers - that's not Savanthood, that's resonance. This can be the reason why Kaladin is able to lend his plate to others. But we know the resonance of Windrunners, it's having more squires then other Orders. Mistborn Era 2 spoiler WoB:

That should not change their Connection to Roshar. Heralds are physical and they still can't travel off-world.

We don't know and Brandon doesn't know it himself what aluminum really does to metals in your body - does it burn them away or just break their Connection to SR. Metal has no power of itself, it glows in CR or to Shardic eyes because it's a conduct to SR which power seeks. That's probably why aluminum (and chromium too) can interfere with that, metal is just too close to SR.

Transformation affects the soul itself, which is in the Spiritual Realm. Dalinar can use Bondsmithing to affect the Spiritual Realm as well. Surges are fundamental forces of Cosmere, which is made out of three interconnected realms. Because of that some Surges will be focused more on one Realm than other, because that's its nature. A mental component of a person is actually just them, what they think. There was no talking there (because that would mean they would be hearing a voice in their head), Jasnah forced change upon them, overcoming the resistance of their souls by using more Stormlight. But Soulcasting at a distance is something that Elsecallers can do, even Lightweavers can learn how to do that, but it's harder for them. If you draw Stormlight from a gemstone very fast it cracks. That often happens in Soulcasting. That's why it cracked. Transportation is not just about traveling to Shadesmar, it's about traveling as a whole. The Oathgates, that are fabrials using the Surge of Transportation, can move you between two different points in the Physical Realm - like from Urithiru to the Shattered Plains - all without entering Shadesmar. Elsecallers can bring other people into CR, what they are doing is creating a mini-perpendicularity and slip themselves into Shadesmar. Lightweavers can move just themselves, no other people and can't go back. Elsecallers might potentially be able to move between the Physical Realm just like the Oathgates can - the way people from Ashyn came to Roshar was by using a huge non-Rosharan, pre-Radiant Elsecalling to move them all from one planet to the other. It's not that far-fetched to say that Jasnah can do something similar (but not on that scale).

I don't think so. Iron in your bloodstream doesn't just sit by itself, alone. It is bound to other molecules or proteins like Transferrin, or Hemoglobin. It's not a pure element anymore, it isn't Allomantically valid. If a tiny bit of impurity makes an alloy Allomantically useless, then a huge molecule full of other stuff will make bound iron impossible to burn. Look at the structure of Hemoglobin, that's a lot of things bound to that iron:

The Oathstone held no power over Szeth, he wasn't bound to it, he just did as he was obligated by the law and his honor. OB ch 92:

And plate spren don't bless their Radiant? I think it's made vague on purpose by Brandon. I agree, it's most likely some kind of Radiant Lesser Spren, because True Spren aren't really attracted to people in the same way as Lesser Spren, they would have to decide to show up in the Physical Realm and many can hide their presence from people. And I think hundreds of True Spren disappearing without any trace would be quite a big deal in Shadesmar cities. It was Taravangian's better day.

Yes. They can resist a few hits of a Shardblade before breaking, but they are a Fabrial. Everything invested enough will resist Shardblade. All ancient Fabrials are spren manifested in the Physical Realm as devices, so I think if you find and convince the right type of spren to do exactly what modern Half-Shard Fabrial does, you can do that. You probably don't even need to be a Radiant. But Syl won't be a Half-Shard, she can just become a shield that will never break - as long as she is bonded and close to Kaladin. We don't know what type of spren was used in Half-Shards, Taravangian said it's "the one that might have blessed a Radiant," but we don't know what it means or what type of spren is that. OB ch 100: RoW ch 46: Metalminds, Awakened objects, Hemalurgic spikes - all will resist Shardblades for a few hits. So they would be like a Half-Shard.

Probably because other attributes store your physical things like muscle mass and you need some bare minimum of that to function at all, while iron vaguely stores mass, which doesn't decrease your size, nor your density, nor your fat, muscles or anything physical. It's the weirdest attribute to store because it has to work weird as mass is essential for basically everything. Can't tell if those numbers are correct, someone smart would have to do precise math. But you need to store a lot of mass to stand on water, or little less than a lot but with running. Either way you need to store a lot.

I think that "point of no return" was when Moash chose revenge over his friendship with Kaladin and the Bridge Four at the end of WoR. It's not about punching Kaladin, not about killing Elhokar, it's just about getting revenge. There was no going back from this moment on because Moash made his choice and all things that happened afterwards just made him dig a deeper hole. He chose to be overwhelmed by vengeance. He was unable to stop himself from killing Elhokar in OB, in WoR he at least hesitated after hearing Kaladin.

Here: By Halfborn we mean a Mistbron + Ferring, or a Full Feruchemist + Misting combo. It's still one or all within each Metallic Art. But there are no Full Feruchemists or Mistborns because those genes are so diluted in the population. But it's possible for someone to be born like that.

It's not about floating due to buoyancy, it's about being light enough to not break surface tension. You can store so much mass that you can actually float in the air, or imitate a microgravity environment - I think walking on water is easier than floating. Yes, it would be hard to get a hang of it, you would lose balance quite often at first, but it's still possible. It would be a very weird feeling, but running on water would be easier than just standing. If the question was can a person run on water then you are right. But the question is can a guy that has a magical ability to reduce his mass down to a feather run on water. Yes, yes he can. Magic solves all your problems. As you store mass your mass to surface area ratio increases dramatically - you can walk, or even stand on water without being a Steelrunner, just store enough mass. There is nothing else a Skimmer needs to do. https://www.youtube.com/watch?app=desktop&v=6jyoBp2dBAo - here is how you calculate surface tension. By my understanding it should work the other way, instead of pulling the object away from water until the tension breaks, push it until it submerges underwater. The surface tension of water is 72mN/m - that means as long as you stay below that value, you will be held by the surface tension of water. And because the equation for it is v=F/2L (for something like a wire), where F=m*a, where m is maas, a is gravitational acceleration for an object at rest, you just need to decrease your mass enough to get that tension value below the breaking point. Disclaimer, I'm not very well versed in that topic, so my understanding of this is flawed. But mass is a big factor in surface tension. Here is another, better example with razor blades - https://user.engineering.uiowa.edu/~fluids/archive/HW/Solutions/2007/Ch01/01_084.pdf. The important part to see here is that for an object to stay on the surface, you need to find equilibrium between its mass and the resultant surface tension. The single edge blade was around 4x heavier and 1/4 shorter than the double edge blade and that's why the single edged blade sank while the double edge blade didn't. A Skimmer can reduce its mass until he finds that equilibrium. That's it. There is nothing else needed. No buoyancy, not even running (but while running you don't have to reduce your mass that much, just like that lizard).

Diagram served its purpose. Taravangian is now a Shard that can look into the future like no mortal can dream of.

Yes, they can. If they are light enough the surface tension will hold them on the surface of the water. There are lizards that can run on water, insects that can stand on it, you can put a needle, paper clip or a razor on the surface - it's all about the surface tension which depends on mass. A Skimmer can stand or run on water, if they can reduce their mass that much (running is easier). It's not about displacement of water at all. The whole idea of the surface tension is that it holds the object despite its density - a razor blade can be held by the surface tension and it's much denser than water. A Skimmer can change his mass (but not density), so he can get so light that buoyancy won't matter anymore, only water's surface tension.

Oh right, but Khriss suspects the Old Magic is something else entirely, so it would not have ten levels.

Small correction, it would make you vulnerable to emotional Allomancy, but one spike in Kandra is not enough for Harmony to seize control. Paalm used Trellium spikes that shielded her from Harmony, but he still was able to sometimes see her. She wasn't fully immune. SoS ch 7:

What's your source that the Old Magic specifically was meant to have 10 "levels" and be related to Voidbinding? I've found nothing. Brandon is always dodgy about the amount of magic systems on Roshar, it depends how you count them because there is no nice and clear division between them. Fabrials are one of Rosharan magic systems and the Old Magis is "its own weird thing," which sounds like it was always meant to be separate from all this binding.

The Old Magic is what Nightwatcher does - she gives boons and curses to people who come to ask her for something, Dalinar was affected by the Old Magic among a few others (his boon and curse was granted to him by Cultivation directly, but that still is the Old Magic). That's really it.

I think it's about whatever Mraize is doing to transport Stormlight out of Roshar. They've already figured out what to do, they just need to blank its Connection to Roshar (not Shards, just to the planet), they need BAM. RoW ch 13: I don't think the same result could be achieved by messing with their soul's Rhythm - you can't make it without any Rhythm, when the sphere with Stormlight leaves the vacuum it will pick up the first Rhythm it hears - Anti-Rhythm in the case of Navani's experiments. Leaving it blanked might be impossible.

That's a very good question. No idea. Possibly. Nightblood isn't made out of anti-investiture, he is full of corrupted investiture and keeps sucking in more and more. But as a solid investiture himself (he kind of is a god metal now), he might be more resilient to effects of anti god metal (or anti-investiture in general) - it might look more or less the same as when he struck a Honorblade (god metal), a big explosion, which didn't kill him. Sucking in gaseous anti-investiture might be more harmful, especially that the corrupted investiture Nightblood holds is under immense pressure, so it might react like mixing Stormlight with Anti-Stormlight in a gemstone. I think giving Nightblood anti-investiture might be a way to kill him, but who knows, Nightblood himself is just an extreme and unique thing.

It will kill you so the effects of it aren't really important. We don't know anything more than that. We don't even know what other properties anti-light has - there is not a single person in Cosmere who would be able to interact with anti-investiture to figure this out. You can't breathe in anti-Stormlight to check how it makes you feel, you can't swallow anti-Atium to see what it does - both of those things would react violently with your soul, destroying it.

Yes, you can stop withering from Shades and on the extreme end aluminum Savant can cleanse his soul of unwanted effects of investiture. It works on everything. Yes. Yes. It should not burn your metalminds away, because they usually aren't inside of your body. It should work like chromium, it could burn your piercings but that might take time. I think it will definitely suck investiture that you're actively tapping out of your metalminds, so just remember not to burn aluminum when tapping a goldmind. But a gold bracelet should be fine - it's not an Allomantic metal reserve, it's not in your body, it should not be affected (but that's unknown, it's possible it would try to but that might take too much aluminum to burn an entire full metalmind away). It's possible that a skilled A-aluminum Misting could use his intent to target specific metals instead of burning off everything. Any metal? No, it wouldn't get rid of lead. Any Allomantic metals? Possible? But because aluminum Mistings are called gnats, I think it's also possible that it would not get rid of metal reserves that aren't usable by that person. How? No. Aluminum doesn't protect you from physical injuries. Normal weapons don't have to be made out of the right Allomantic alloy, so it may not work on them at all. And because chromium burns quickly and affects small metals first, you would probably need a TON of aluminum to burn an entire sword away. That won't work. Unknown. Chromium can do that, but it requires a lot of it. Having a right intent should also be required - in BoM Wax was hit with a granate charged with A-chromium, it burned his steel reserves away but not his metalmind. In TLM Wayne was fighting a Leecher and his metalminds were unaffected. This in my opinion suggests that you have to have the right intent to use chromium and aluminum to burn something else, like piercings, or metalminds. Oh and I've just remembered this WoB after writing all of this. An inquisitor burning aluminum would not destroy his spikes - this implies that aluminum won't work on spikes and metalminds, but it's still possible that a precise intent is needed to do that (at least with metalminds). That's a good question. Spikes are unaffected so a Divine Breath might be unaffected as well. And it's not an unwanted effect of investiture. But that would probably take a lot of aluminum.
