@Frustration It's an interesting video but I don't see how the Leidenfrost effect is applicable to Marasi and air friction.

This is a bit tricky. Moving at Mach 17.62, even for a short distance, should cause a lot of friction, and therefore heat - I think. However, during the course of like 20 minutes or so of googling and reading various things last night, I was not able to find useful information to inform myself about how fast air friction would begin to cause heat and how much heat would be caused. My gut tells me that even though she moved a very short distance, moving fast enough to leave an air vacuum should have produced a non-trivial amount of heat friction. If any scientifically minded users can chime in on this (such as @therunner), I'd love to hear from you. You briefly touched on it here, especially when you mentioned the clothing. The inference appears to be that you would have expected there to be significant heat, such that we should have seen damage to her clothing from it?

@therunner I was a bit nervous when I made that part of my post about the Newtons, precisely because I was worried I was doing it incorrectly, so I have no issue whatsoever with your corrections. In fact, I welcome them! I appreciate and enjoy your attentiveness to detail.

The Lockheed SR-71 Blackbird is the fastest aircraft that we've ever created, clocking in around Mach 3.2. Marasi has already doubled that, as per your conservative estimate of Mach 7~. Marasi did not replenish her available speed by storing, she did not compound, and we do not know how much she had to begin with. She did not experience any deleterious effects, whatsoever, when moving at Mach 17.62. If you want to assert that the Metallic Artists can't reach impressive multiples of Mach speed, I'm open to that - but I don't think there's much standing in the way, given the raw speed of C-Steel and the mitigating assistance from C-Gold, F-Brass, etc. I welcome further debate on this topic. In order to give this some practical application to this speed... The Barrett M82 has a muzzle velocity of 853 m / s and the largest .50 BMG is 800 grams. Mach 17.62 works out to 6043.66 m / s. A .50 BMG weighing 800 grams, traveling at the Barrett M82's muzzle velocity of 853 m / s, is 705.6 Newtons of force. A 10 kilogram metal sphere thrown at a velocity of 3,430 m / s, or Mach 10, is 34,300 Newtons of force. In other words, that thrown metal sphere would have almost 50 times (actually 48.11...) as much force as a bullet from the proverbial fifty caliber sniper rifle. Dare I say that our hypothetical Shardplate has it's work cut out for it?

If anything, C-Steel should be far more potent than this thread has, as of yet, given it credit for. https://wob.coppermind.net/events/305/#e8085 tells us that you could get close to the speed of light, with C-Steel. speed of light = 299,792,458 m / s speed of sound = 343 m / s In other words, the speed of light is 874,030.489796 times the speed of sound (299,792,458 / 343), or Mach 874,030. How close is "close" to the speed of light? Well, let's look at some numbers: 1/2 or 50% = Mach 437,015 1/4 or 25% = Mach 218,507 1/10 or 10% = Mach 87,403 1/100 or 1% = Mach 8,740 1/1,000 or 0.1% = Mach 874 1/10,000 or 0.01% = Mach 87 Even a very conservative reading of "close" is many times more than any of the numbers thrown around in here. For emphasis, here is the relevant WoB excerpt again: You could get close Although air resistance poses difficulties in the form of air resistance and heat, we know for a fact, as per Brandon, that it is possible to get close to the speed of light, with C-Steel. As for surviving the effects of air resistance? F-Brass can deal with heat. C-Gold can heal, among other things... point-blank dynamite, decapitation, Hemalurgical Spiking, and death (Waxillium). It should have no issue restoring tissue damage from heat, broken bones from air resistance, or whatever else might arise.

Applying this WoB to what you suggest: "you become immune to the effects of the ability only." Tapping heat would only make you immune to the effects of the heat that you tapped, it is not a magic bullet for solving all heat-related problems from other sources. The takeaway is that tapping heat won't light you on fire, but it also won't protect you from burning up due to air friction. "Growing colder, however, would be more helpful in this regard." Tapping heat is how F-Bronze helps you deal with low body temperatures caused by being in a cold environment, as demonstrated in The Bands of Mourning... Logical inference and this WoB tells us that... Storing heat is how F-Bronze helps you deal with high body temperatures such as those caused by air friction. Otherwise, our erstwhile heroes in Bands of Mourning would not tap heat to deal with cold environments. They would store heat. However, we demonstrably observe them tapping heat in order to deal with cold environments.

No, you've got it backwards. 1. Storing heat cools you down 2. Tapping heat heats you up Since Marasi was not storing, she necessarily was not capable of cooling herself off.

But she was not storing anything, such as Heat via F-Bronze. Marasi did not experience problematic heat despite moving at your estimated Mach 7. She didn't even comment on becoming uncomfortably warm. In fact, she said nothing, whatsoever, about heat.

What, precisely, does make someone worthy of Bondsmith powers? As seen in RoW's Part 1 Epigraphs, Navani attempted to get the various human factions to come together (uniting?) in order to share technological information and assist one another in the development of further technology. As we see later on in RoW, Navani successfully convinced them to share the secret of how to quickly transfer light between Gems. Navani was willing to work with Raboniel (uniting), despite their differences and status as enemies. A human displaying the willingness to discuss, learn from, get to know, and collaborate with a Fused is a rare thing. Throughout RoW, Navani demonstrates her willingness to reach out to disparate human factions as well as a fused. Textually, she is quite literally serving the role of an emulsifier. I would be interested in hearing about the ways in which you think Dalinar was worthy, while Navani was apparently unworthy.

A & F Pewter strength can help overcome resistance and, as I noted in an edit to my previous post, F-Bronze could assist in avoiding the deleterious effects of heat. F-Gold can also heal from the negative effects thereof. Finally, WoBs can say anything they like, but Marasi noted absolutely nothing in the way of heating up due to her speed or having to deal with wind resistance. I'll be far more inclined to worry about air friction if it actually makes it into the books when Metallic Artists go fast.

The heat and friction are easily solvable. 1. Store heat with F-Brass. 2. As @BenduLuke suggested, wear appropriate protective clothing/armor. Edit: Alternative means: Acknowledge that you might become a human torch while dabbing on the proverbial tortoise-shelled-Rosharan-slowpokes and Heal yourself with F-Gold.

The devastation of Ashyn involved a Dawnshard and I think we've already conceded that if Ishar was given a Dawnshard he stands a very good chance of singlehandedly devastating Scadrial. Without a Dawnshard, I am highly skeptical that Radiants would be capable of such feats without a Dawnshard amping them up. Rysn swore that she would not bond a truespren. If Rysn became a Radiant, she would immediately be in violation of an Oath, which would probably kill her spren right then and there. If anyone wants to seriously propose the Dawnshard be used in this conflict - just bear in mind that doing so probably requires that Rysn be killed in order for someone else to pick up her Dawnshard.

I take that WoB to be referring to the actual conceptual creation or invention - in other words, when Harmony first made Ettmetal into an actual thing that could exist. I think the "laws of the realm" mean that this new element came about because Vessels have corresponding Godmetals, and Sazed happens to be holding two shards, thus he will result in a hybrid Godmetal.

Do we actually know whether Harmony is actively or passiveliy providing the Ettmetal? e.g. if it is a Pits of Hathsin-esque process or if Sazed claps his hands and poofs some Ettmetal into existence? Comedic value of the latter example aside, I don't think we do. All we know for sure is that Sazed has provided the So-Scadrians with access to Ettmetal.

Waxillium Ladrian is 41 years old, meaning that Harmony necessarily enabled him to use the Mists at some point within the past 41 years. In other words, Harmony has recently proven capable of granting access to the Mists. Taking the Stormfather off of Roshar would likely have grave consequences, including but not limited to: No more crem deposits No more Stormlight distribution - Rosharan fauna depend on crem and stormlight, iirc. Singers would lose access to the forms that they obtain by going into the Highstorm, and would only be able to change into forms they obtain by going into the Everstorm.
