Spren. Their bodies can shapeshift fairly easily and don't have to follow bone physics. They'd need to be highly Invested to interact physically, but that's achievable. Maybe a Substantiated Lightweaving or piece of Midnight Essence could do it too.

How does Emotional Allomancy factor into this hypothesis? Investiture projected by Emotional Allomancers cannot penetrate aluminum, and there's even a field effect that will block it from a small surrounding area.

Welcome to the Shard! We don't have any true numbers for most of these yet, but Metalborn themselves are not terribly rare. Less than 1 out of 50 people will be Metalborn though, but we don't have exact numbers. Twinborn will be rarer than Ferrings or Mistings. We learn in passing in book 3 of Wax and Wayne that there have only ever been 3 Crashers (Allomantic steel/Feruchemical iron Twinborn) recorded in Scadrial's history. Assuming Compounders are as likely to exist as any other Twinborn type (which may not be entirely true, it's been debated whether certain types of powers like Allomantic steel are more common than others) you could very roughly expect a single Compounder of each type to exist once every century. It also should be noted that the type of Allomancer or Feruchemist you are appears to be mostly random- you'll have a higher chance of having one if your parent had one, but you won't necessarily be the same type of Metalborn power.

Friend, you have no idea.

I don't know, he was able to survive an indeterminate (but very long, compared to most Invested entities) time in the CR. He eventually held the entirety of a Shard as well, which I think would be more than Endowment would be willing to fork over, even temporarily. I think it would be safe to assume killing his physical form will only set him back to that state, in which a more permanent method must be used to end him. That's directly linked to powers though (wait, would power spikes strip a Fused of their immortality?) I think duralumin might be better, if Connection is what anchors him. If it's Connection due to raw Investiture, usa big nicro spike.

Won't his Cognitive Shadow still be around in Shadesmar though? He should be able to get back eventually, especially with his organization backing him.

So basically I just have to make sure I teleport to a place that is utterly safe or I die unless I have a form of regeneration. Interesting. I'll have to aim for a nearby janitor's closet then, since there isn't as much (immediately) dangerous stuff in there. Actually, a bit off topic, but does the Sibling need janitors to clean their insides? Or is that job automatic for them as well? Anyways, I'll also want to expect a bit of recouperation time after Traversing to get in the Tower and I will want to set up a cushioned saferoom beforehand for my return so I can escape whenever I feel the need to.

Book of Nails has been on my top list for a while now. More Scadrial and more HEMALURGY is more than enough to convince me. Caveman Heist sounds so bizarre and different than what I'm used to in the Cosmere that I now really want to read it. Silence Divine I think we got a tiny sliver of, and now I want to finish it to see the rest of the disease magic. Grand Apparatus should be pretty cool, especially after recent events in books.

Well, for material items it could be done via trading with other people. Cultivation has followers and agents. Or, I suppose it could be Soulcasting and that would muck things up a bit for my original idea assuming it cannot be replicated with sufficient Connection fiddling. Personally, I think it could. My current thought process is that most forms of magic rely on some form of Connection manipulation at their core. Elantris spoilers: It does appear after re-reading the WoB though that it is not purely Connection manipulation though, so I may have to drop that previous assumption of mine down a peg. Still comes into play for most magics though, I'm thinking.

Oh, I'm just having a bit of fun is all. . . Got it. Let's see, one boon is preferable. This is by far the most potent resource I have, so I need to use it wisely, preferably to give me some ability that is extremely hard to counter, allows me to enter the Sibling to assassinate Jasnah I mean Navani, and still work within the lines of Cosmere mechanics and the Nightwatcher's power. Let's go with an ability similar to Nomad's Skipping, but hopefully with a little more fine tuned control so that I can pop in, do what I need to, then pop out. If I can get a Shardblade somehow and take it with me I can use it to crack the amber shield Navani has. Actually, as the OP @Aliroz-The-Confused you should probably choose a fitting curse for me to go along with my Skipping power. Then I'll have to come up with a way to sidestep it. Oh ho ho, I see how it is. Captain.

The Old Magic (at least the more modern rendition directly stemming from Cultivation and the Nightwatcher) seems a bit like it is hand-wavy on just how it works. Presumably there is an infusion of Investiture in many cases, but other than that it's pretty mysterious. I wonder though, isn't it pretty convenient that the only known Spren to be capable of giving Boons and Curses (Cultivation doesn't count) is also a Bondsmith Spren? I hypothesize that the Boons and Curses are merely a matter of complex Bondsmithing, adding, changing, and deleting Connections in order to shape the person receiving the boon/curse and their Investiture appropriately.

*Herms and haws in a totally justified and sincerely arrogant fashion* Was not the Herald killing thread the one to kick it all off? Question: do we get to ask for boons from the Nightwatcher? Do they still come with curses? Are we limited to one (otherwise it might get broken pretty fast)?

So, the goal isn't to kill Nightblood, but the wielder (let's say Szeth, since he's the last user and has competence with most of the Surges). Regardless, I don't think this is actually that difficult, at least compared to killing Nergaoul or a Herald. The user is mostly just an Honorbearer, but with an instant-kill Blade if they happen to touch you, but said Blade is draining their Investiture at an exponential rate until it consumes the wielder too. Even with White Sand all around them, I'm pretty sure it's less Investiture dense than gemstones or Breaths. That's just a hunch, but even if that isn't the case the exponential greed of Nightblood will very quickly make using the artifact impossible- you'd need to keep moving to new patches of sand until it drained the Investiture too fast to keep up with. The Blade can be largely countered with large amounts of aluminum armor and firearms. Swords are a lot less effective when they can't hit you. The Surges themselves are probably a lot more dangerous to you and your hired muscle, especially in the hands of someone competent. However, aluminum can help block the most directly dangerous types, like Soulcasting or Releasing, and again, using those Surges will only quicken the rate at which they deplete their available Investiture. I think the situation is similar to that of killing a Mistborn- the user is a glass canon, and can dish out a lot of damage, but realistically cannot take a lot. They even have an additional weakness in their instability and rapid Investiture consumption. They're definitely more dangerous up close, but aluminum is a really great shield against that.

Now, hold on a minute- who am I in this scenario? Am I just some schmuck that lives on Taldain? Do I have knowledge of the Cosmere and other worlds? Do I have any resources from Auto, or am I purely on my own?

Don't forget that in addition for Flaring and enhancement metals that make an Allomancer temporarily stronger that those with innately more Investiture squeeze more out of their metals. Lerasium (as you bring up in the title), the Well of Ascension, and Savantism can all widen the gates used to Invest the Allomancer. Plus, we've have seen people swallow larger individual pieces of metal before, such as when Vin and Kelsier needed to Pewterdrag for an extended period of time and ingested entire beads. Those are individual pieces, as are the flakes they normally burn, but there are not individual wells of power they sense nor do they get any boost from stomaching more metal. You could possibly chalk this up to perception again, but I feel like the evidence is stacked pretty hard against this hypothesis. The innate level of Investiture or other enhancing Investiture is the primary thing that determines an Allomancer's potency at burning metals.

I don't think that metals on their own would have an impact on a Shardblade's function (aside from aluminum or highly Invested metals in blocking their magical edge). It would be simple enough that steel, bronze, copper, or other metals that come in close contact should have had a noticeable impact, but we don't hear of this. I do think it would be possible in theory to create a Fabrial, possibly one that harnessed duralumin, to enhance a Blade, but we haven't seen direct evidence for such a contraption yet. For broader back and forth discussions, I would recommend creating a thread in the Cosmere Discussion forum. Q&A is typically best for questions regarding Cosmere stuff that you would like a direct answer for. No harm done or anything, it's just easier for everyone involved with that setup.

Okay, so I purchased the digital book Stormlight Scenarios from Demiplane. For one of the quests, a big factor is that one of the high-ranking Fused grew romantic feelings for a Radiant and vice versa, causing them to betray Odium. This feels. . . off? They're literally millennia old, have been fighting, killing, and dying to humans and later Radiants for ages, and are permeated with Odium's essence of loud, selfish emotions. I mean, I guess it's not impossible- people have their own agency and uniqueness. But this just feels too implausible in my opinion, and may have been shoehorned in for the sake of the RPG. Would anybody care to show me a different (or aligning) perspective? I would actually like to hear what other people think of this scenario.

Excellent question. Duralumin, despite being mostly comprised of aluminum, has a different spiritual set of properties. So, an aluminum shield would negate the vorpal edge of the Shardblade (though it can be cut through regular means if it's thin enough), but a duralumin shield should be cut as any other metal.

From what we've seen, it appears that each, or at least some, forms of Surgebinding have a more advanced use that is not as intuitive as their standard use for Radiants. Transportation not only lets you create miniature Perpendicularities, you can use it to teleport long distances as seen by Ishar in the SR visions. Adhesion (possibly conjoined with Gravitation) can be used to affect pressure differentials, creating bubbles of still air. Bondsmiths can use Adhesion (possibly conjoined with Tension) to affect the spiritual, not just the physical. While these may not all be using the same mechanism to achieve new results (though they may. We don't have enough info yet), they are certainly using something different than their basic Surges. I've been wondering about Soulcasting specifically, as it feels like one of the higher potential Surges. Normally, you alter an object's or being's Spiritweb to transform it into another physical essence, or to purge unwanted essences (like poison from the bloodstream). I wonder, could you edit a Spiritweb in more complex ways? You'd need a good visualization, but as meat, grain, and blood prove you don't need a perfect image of biology to make complex biological structures- it's the Intent matters more with Surgebinding, as Khriss would say (which does require a level of technical knowledge, but not a perfect one). Perhaps a Soulcaster who had a great deal of practice and medical knowledge could change a person's body in a way that Progression cannot achieve, such as adding muscles, limbs, or organs. We've seen that Raboniel was able to begin corrupting and Unmaking the Sibling, and while she's pretty unique amongst the Fused (even having her own Rhythm) her main power is Transformation. I strongly suspect that her ability to corrupt Spren is directly related to her Surge, and I further suspect that other Surgebinders with enough power and know how could achieve a similar result.

I've been thinking, both Nohadon's and Hoid's Spiritual Realm echoes are exceedingly aware and capable. They can speak and adapt in a way that does not seem to be possible to the standard echo. I offer a hypothesis for this- both individuals, I believe, held a Dawnshard or very large portion of Investiture at some point, turning them into Slivers or Sliver-adjacent beings. Hoid is confirmed for this, and while Nohadon himself is an unknown we know he was special amongst the Surgebinders, and Dawnshards have had a history with Ashyn and Roshar (though it's also very likely he could have been a Bondsmith). A Sliver or Dawnsliver might have a larger echo in the SR due to their expanded Spiritweb and Connections to their power. As an alternative hypothesis, both are quite knowledgable. Hoid for obvious reasons- he's Hoid. Nohadon had a knowledge of Realmatics, as he educated Dalinar on the topic during on of his visions. This could also explain the phenomena of self-aware SR echoes, as the Investiture seeking to replicate them thinks that they would be aware of their predicament (I believe not-Wit himself says something along these lines, but unreliable narration is a thing, so it's not the only possibility). In any case, we see that self-aware SR echoes/shadows are a thing, and that makes me wonder how they could shake things up. Could they be seen and interact with someone who had visions of the SR (okay, Dalinar does this, so I think yes)? Maybe an Oracle or Auger could see a more dynamic and communicative version of themselves when burning their metals. Or, could they make their way to the PR? Items can be pulled out via Perpendicularity, as we see with Navani taking Shalash's hair ribbon (I think that was what they took, right?). Cognitive Shadows can't do this with a Perpendicularity, so there may need to be an extra step, like Hemalurgy, but I think it's possible to bring a SR echo out of the SR if you wanted to.

Welcome to the Shard! I don't think I've ever considered this before. Allomantic nicrosil only targets kinetic Investiture from what we've seen, so after the Blade is summoned I don't believe it would have an effect. However, Shardblades are kinetic during the act of summoning, so I think you might be able to summon a Deadeye Blade instantaneously with the application of duralumin or maybe nicrosil since you probably can count it as a separate being. Edit: whoops, you meant Feruchemical nicrosil, my bad. I think you might be able to store some residual Investiture, the kind that lightens your eyes and is passed down to your offspring, but the bond itself is probably more duralumin Feruchemy territory.

Yeah, you could just do that. But for some reason it seems like there's been a restriction on Unsealed Metalmind use (though that might just be the meta getting in the way in all the secret projects). There are also time periods where that might be harder to do. For example, if Sazed had lent Metalborn to Roshar during the True Desolation there's a good chance medallion tech wouldn't have been up to spec yet. But yeah, artificial powers will probably make many things redundant in the future.

I just have to jump in and say ditto on that. This is my current assumption for how aluminum Hemalurgy would work.

I asked them that question a few days ago. They told me they don't know how to do it.

Yup, the ones with spikes through the eye sockets.
