Are we still accepting suggestions on this one? When I was thinking about Nightblood Ascending I came up with Crusade as a tentative flavour of Dominion×Devotion. Perhaps if it were reinforced by a third Shard like Odium or Ambition?

This should be correct. If you're confused about what he's talking about, remember that momentum = mass * velocity. By conservation of momentum, if you're halving your mass, then you double your speed/velocity, and if you double your mass then you halve your speed. Feruchemical iron relies on Investiture to make up the difference and ensure conservation of energy, as kinetic energy = ½ * mass * velocity², so halving your mass and doubling velocity would end up doubling your kinetic energy. This does suggest some really interesting things about Investiture and energy as a conversion, as it implies that when you Invest in an iron metalmind you're decreasing in some form of potential energy, but that's rather beyond the scope of the question.

A lot of Ruin/Preservation's abilities on Scadrial are caused by the fact that they created the entire planet and all the people on it, rather than just finding it premade and working from there. So it's possible that a Rosharan would have to work a lot harder than a Scadrian to open themselves up to the influence of Harmony; perhaps a Scadrian with that kind of spiritweb damage could hear Harmony's voice in their head, but there aren't many Scadrians facing the pointy end of a Shardblade these days.

I've seen all of those before and they don't really support or deny anything in this thread. We are not attacking the focused power of two Shards with Nightblood, but rather throwing Nightblood at a raging storm of Investiture which is equivalent to the power of two Shards.

@Nameless @Booknerd what do you think about the Intent question, by the way? I was really struggling to come up with a good Dominion×Devotion Intent that matches Nightblood.

"He died as he lived; bursting with energy."

Actually if I'm wrong then we could just wander in and carefully sheath Nightblood while in the now-clear dead zone. Imagine this: Kelsier's Sel equivalent dies and latches onto the Elantris perpendicularity. He goes to find the local God and give him a piece of his mind, and also soul, and instead there's just a giant sword screaming DESTROY EVIL! at the centre of a huge accretion disc of pure Investiture.

I have reasons to doubt this. As I said, the Dor seems to be built on pressure — that's one of the main conflicts that Raoden endures in Elantris; the Dor keeps trying to push through him to relieve the pressure. If there were a null spot, then the Dor would have a concentration/pressure/etc gradient which would push it into that area to be sucked up, kind of like a vacuum cleaner (maybe a black hole is a better comparison?).

I was taking a gander at all of the posts on the Arcanum about Nightblood, and I couldn't find anything which exactly answers this question. Here's the information/assumptions I started with: Nightblood is powerful™: perhaps the strongest non-Shardic object in the history of the Cosmere, maybe ever (though that's still basically nothing compared to an actual Shard) The Dor is effectively the power of two Shards all trapped within the Cognitive Realm around Sel, a bit like a 40k Warp Storm but with fewer Daemons (hopefully). Nightblood really likes eating Investiture.[Citation needed] The Dor would not pull back from Nightblood in the way that the mists would, as they seem to be very pressure-driven and totally mindless, rather than being connected to a living Shard. Here's my proposal: Get Nightblood to Sel with an Elsecaller who really doesn't have much to live for. This is a trivial step and left as an exercise to the reader. Transfer Nightblood to the Cognitive Realm using said suicidal Elsecaller, while the sword is unsheathed. This should actually be pretty straightforward, from what I understand about Elsecalling. I'd rather not go via a Perpendicularity here, because Brandon's suggested that they might just collapse. That's not a very reliable way of accessing the Dor. Doing this rather than as per my initial phrasing of the question would mean that Nightblood appears in "the middle" of the Dor, rather than on the edges where any effects might not be so great. Wait a couple months. My hypothesis is that Nightblood would happily devour all of the nearby Dominion and Devotion Investiture; the result of this slow cooking at 70°C would be Nightblood becoming significantly more powerful and tender, perhaps even to the point of being Shard-threateningly powerful. Among the Shards, Odium is torn because on the one hand, Passion, but on the other hand, dying, while peaceable folk like Autonomy just wet themselves in fear and made another dozen Avatars to try to relax, and Endowment is consumed with equal parts laughter and terror. In other news, Vasher goes back to Nalthis and kills Shashara again just on principle. The other options are far more terrifying in my opinion: either Nightblood overloads from destroying so much evil and explodes, killing anyone nearby and losing us Sword-nimi as a character, or Nightblood Ascends and takes on the Shards of Dominion and Devotion in some capacity. Brandon hasn't committed to whether Nightblood could Ascend, but assuming it could I'd be interested to hear what you guys think its Intent would be as a combined Dominion/Devotion. Crusade; being Dominion over "evil" and Devotion to the sword's Command?

If the Surgebinder (presuming for the moment that they're a Windrunner) understood Atium, then they'd just sit a ways away and start lobbing rocks at you with Basic Lashings. A fist-size rock that's been falling for a hundred yards is not something you want to get hit by, and at some point as you throw more of them you either force the Mistborn to dance and use up their iron/steel/pewter, or use atium for more economical dodges. Alternatively, Shardbows work too. Stay at a range where you can't dodge them reflexively and the only option is to use Atium or copious amounts of Steel.

Somehow Brandon manages to hold his cards close to his chest, and also give us so much information… Unless I'm mistaken, Lerasium is practically impossible to get now that Leras has come down with a severe case of Ruin, so Mistborn is now difficult. Still, I'd forgotten about how easy it's going to be to get unsealed and unkeyed metalminds in the future — make unsealed metalminds which grant the power to make more unsealed metalminds, and you can flood the cross-cosmere market, right? Provided that you have enough Excisors and the raw nicrosil for it, of course. Actually, Knowledgeable One, while you're here, something has always bugged me about the distribution of powers within the Knights Radiant. The 10 orders of higher spren all have a nice pairing of surges going on, forming that very Vorin ring shape. However, honorspren and exclusively honorspren are described in the SA books as being created by and parts of Honor. Which begs the question: why do they fit in with the rest of the higher spren? They seem to be unique in that they are Splinters of Honor, where the other Nahel Bond spren are in some way different, and yet it's just like they complete the cycle and fit in as one of many spren. Oathbringer is basically chock-a-block with references to 9 types of Odium creations and spren, so my tentative hypothesis which I am 100% making up as I write this would be that Rosharan magic is organized into multiples of 3 (3 Shards, leading to 3 systems, each with 9 facets), like how Scadrial is base 16, and the 10th type of 'normal' Honor-ific spren is effectively Honor 'interfering' and creating an extra type of spren for his magic system. Am I just overthinking it?

Thanks! I have a bad habit of lurking for years in case I make a misstep without realizing. I must admit, I had seen some already, especially regarding Vasher, but it's very pleasing to hear that someone else has done all of the heavy lifting and gotten answers for these questions. Huh, that's... interesting. It seems I really don't remember what Cognitive Shadows are, then. I assumed that Szeth wouldn't count because of the method by which his soul got dragged back into his body, but having checked the wiki it seems I underestimated how broad the definition is. My reasoning behind this was that it doesn't seem like it would be as large a change as some of the ones we see in TES, if one were (for example) born as a non-mistborn member of a family with a very strong history of Mistborn and Mistings; your spiritweb would have been in close contact with many closely related Mistborn, and in terms of a 'difference', it's a small change to imagine that the genetics went by chance the other way. Do you think that's a poor analysis of it? This seems to apply to a lot of other magic systems — it's really difficult to get into unless you're from the culture or planet where it originates from. I wonder how much of that is just Brandon's meta-level storybuilding so that we do not have tonnes of magic systems crossing over except in noteworthy characters — if a character is a Surgebinding Elantrian, or a SoulForging Awakener (wow that would be quite the combo...), then it would be so powerful that they would be hilariously overpowered from a narrative perspective through that alone; however, if it is a main character and they are unique, it suddenly justifies otherwise large levels of plot armour.

I was wondering about this on my most recent read-through of Warbreaker & SA, because in Mistborn Era 2 we've seen that combining Feruchemy and Allomancy produces some really neat things; I wonder if we have received any confirmation about how other magic systems might interact. Also Hoid is living out his inner Ash Ketchum with Shardic powers so it's going to come up in the future. So yeah, Awakening and Surgebinding. Returned are, according to the coppermind wiki, Cognitive Shadows, however, as shown by Nale becoming a full Skybreaker, that doesn't exactly stop the Nahel bond from forming. Which raises a question: can a Returned become a Surgebinder? If they were to do so, would the different forms of Investiture combine, to allow them to go out into a highstorm with some bright clothes and start mass-Awakening big things? On the other side of things, if one were to create coloured illusions via Lightweaving, could this be used as a source of colour for Awakening? Speaking of Returned, could Type IV BioChromatic Entities become Surgebinders (imagine Nightblood the Windrunner, with its spren taking on the form of a person wielding the sword...)? Going the other way, could a Surgebinder Return? How would that affect the Nahel bond? Would their death cause it to break, and then they would have to spend time reforming it and reswearing the Ideals? Would the newly-Returned even remember their spren? Assuming that it can happen, we're presented with a number of interesting implications. If we fast forward to the more interconnected Cosmere which is coming in later Mistborn eras, it would be really cool to see artists try to desperately acquire a large number of Breaths and a Cryptic or Truthwatcher spren in order to become a better artist. Returned have a headstart by being propelled up into the 5th Heightening straight away, with all of the cool art appreciation features that come with that; a Returned with access to Lightweaving could conceivably create illusion-based 3D artwork with all of the depth and complexity that only another massively Invested Nalthian (or perhaps a Tin savant / relevant Feruchemist?) could appreciate. Add in SoulForging and you've got a seriously upmarket art installation. On the topic of SoulForging, if you spent time on Nalthis and Roshar, could a Forger rewrite your spiritweb to make it so that you became a Surgebinder or Returned? Or an Allomancer/Feruchemist based on a life spent on Scadrial? How would that work?
