I dont think so, but I could be wrong. My understanding of the push/pull issue for metalminds is more from their being Invested at all but not so much from Identity interference. I think the same can be said for the resistance to Pushing/Pulling on metal that is inside somebody. A case example being that Drabs are easier to Push but seem to have fully functioning and unique Identity (which is why an awakener cant take their animating Breath back.

Agreed, and Ive long expected to see exactly that eventually. At minimum it would be a very reasonable and humane (assuming it's reversable) way to contain metalborn and/or off-world criminals while they're actually in prison, but it might also be a sort of parole where they are allowed Out but not allowed to keep their powers active. That becomes a whole other can of worms that will depend heavily on the cultural outlook on Hemalurgy. It would make sense for people who are about to Die to want to leave a piece of themselves for their family and heirs, etc. But it's so easy to abuse with good ol' fashioned Murder that it would inevitably become a legal flashpoint. Just like the RL debates about assisted Suicide, there's a lot to untangle before the whole population would accept it. I doubt it would ever get to the point of Harvesting inmates against their will, but I could see a blanket Cultural Right to leave a piece of yourself behind that could still be open to inmates.

A Kumquat A Spider + a Demonic Bargain

Yes, the working theory is that it grounds out investiture (in the electrical sense). Per WOB's about Cosmere continuity, no Investiture can stick to aluminum*. So in the physical world it blocks investiture effects like a Faraday Cage for Investiture. And if you actually realmically interface it with your spiritweb directly, as with Hemalurgy, it prevents you from ever channeling Investiture and/or creating Investiture-based effects while it's inserted in your spiritweb. So while you have a part-aluminum spiritweb, thanks to the spike plugged into it, you'd be unable to use allomancy, feruchemy, sandmaster (per WOB), and presumably Surges, honorblades, or anything else that requires a Bond or Investiture to pass into, out of, or through you. *Which means that neither aluminum metalminds or aluminum Spikes ever actually gain an Investiture Charge, which is consistent with the evidence so far. Under this explanation it's interference rather than destruction (consistent with the Aluminum vs Silver WOBs) so logically those powers would come back once the Spike was removed unless they are specifically fragile. For example, it might just Kill a Returned because of the Divine Breath aspect of their Spiritweb, but since WOB says normal breaths are in the body and not the spiritweb, they might be safe. Im guessing that a Radiant bond would be suppress but not destroyed (the way leeching does not permanently sever it), and ditto Aviar bonds. Im assuming that All Powers interference would extend to things that create weak/temporary bonds like Midnight Essence spores, honorblades, or medallions. But anything that can operate entirely without sapient intervention like ettmetal devices or most rosharan fabrials would be safe unless the aluminum was physically close/touching it (to interfere the normal aluminum way).

The spike works by essentially adding additional functional parts of spiritweb to yours, and since Aluminum spikes can affect more than just scadrian magics I think it would be able to block your use of the powers regardless of whether it was natural or hemalurgic. I think the weirder question would be how it interacts with medallions. They are more external but still create and require a Bond to function, so the Aluminum Spike should block those Powers too. Ettmetal Grenades, on the other hand, require no interaction or Intent from a person so the aluminum spike would not block it.

It also might not have mattered in those specific instances, since any bind point would work equally. There are two scenario's where all bind points logically act the same: Aluminum Power Blocking Spikes, and Shardic Control of Kandra via two or more spikes. For those you dont care about a successful removal of Spiritweb or reintegration, just the basic realmic effect of the spike's presence. And hitting ANY bind point is a lot easier than hitting a specific one, and there are some specific ones that are relatively big targets. Shooting somebody through the eye socket is well withing Wax's abilities, for example, and WOB says there's a dense cluster of them around the heart so it might legitimately be hard to miss them all with a heart shot. PS. If we're talking about the night wax shot Paalm, Wax was not spiked at the time because that spike is the one he turned into a bullet and shot her with. He didnt shoot her with aluminum, it was his Pathian earring made into a bullet.

Agreed. Not to mention that if Fear of the Singers had been the 16's primary motivation, then the first thing the Shards would have done after taking BigA's power would have been to descend on Roshar and blast all the singers into oblivion. They wouldnt have been left to whichever Shards wandered by.

Meanwhile, Per WOB Rosharans are one material science lesson away from having nukes in Dalinar's technological era.

What are you looking at for circuit functionality, LED lighting or EV wire maybe? I would suggest considering more of a base, perhaps including some of the natural mountainside that it rises from, so that you have enough space for a battery cavity and any control circuit you'll need.

Agreed, especially since Aluminum being off-limits for Investiture effects is apparently considered such a continuity element that Peter wont allow Brandon to make the shardblade guards out of aluminum.

Agreed. And a big part of the classic Mutant Registration conversation is the inherent dangers posed by the entirely random and potentially catastrophic powers people might gain, but the Metallic Arts as they stand now are just not that Unknown to the general population, and overall getting weaker rather than trending stronger like Mutant powers. That sort of registration would probably be limited to off-worlders (which might arguably be a reasonable immigration policy) and any revival of the full Mistborn or Feruchemist of legend that might be unlocked through their scientific advancement. Also I could see a very strict and detailed system tracking Hemalurgic Spikes. For society's sake Hemulurgy would need to be either outlawed or heavily tracked and regulated to ensure spikes are either historical enough to predate laws or were created under whatever their "modern" definition of humanely harvested might be (full written consent of a terminal Donor, Heirloom family Spikes, etc).

I dont think we'll see magic surveillance Cameras for that sort of thing, but I could see ettmetal tech that uses A-Bronze to detect and alarm in the event of a nearby allomantic Burn.

Even in the final empire it was considered bothersome that allomancers would use metals in buildings for their anchors and cause damage because they weren't stout enough to support a full person's weight, etc. So I think at minimum you'll see specifically designated lanes and "roads" with stout metal anchors that they have been built and installed to support the allomantic acrobatics. Anyone caught using other metals and/or actually causing harm would face appropriate legal penalties, akin to driving on a sidewalk or through a park. I could see individual cities having ordinances against dropping metal trash as your own personal anchor (like the spent bullet shells Wax used). So I could see that getting caught up in littering laws. Though I could also see there being a specifically stated exception for using Coins and just calling that a nominal act of charity for whomever picks the coin up later on.

You are storing/tapping your Body's warm-blooded ability to generate Heat internally. But it's that Internal heat generating capability, not raw Thermal energy storage. So for example, to survive a hot environment you cant resist it by raising your body temperature to match it (per the WOB but I might argue the thermodynamics there), but you could lower your body temp to counter the environmental effects.

They certainly could, but they'd be in extremely high demand for both honest and corrupt work. So it would essentially be all the different tropes for why a talented young person might fall in with Organized Crime instead of the honest job their grandmother always wanted.

To be fair, it's still an open question whether any of the three Metallic Arts are capable of making Investiture stick to aluminum, which would otherwise be unique in the cosmere. WOB says that compounding aluminuim wont be useful, which I think is because Aluminum metalminds dont ever actually gain investiture so there's no Charge to compound. Similarly, I can't think of any logical Spiritweb chunk you'd need to Intentionally rip out to get an aluminum spike to work, but Im open to suggestions. Otherwise it seems like Aluminum still just grounds out Investiture rather than being affected by it, which would explain why it's feruchemcial power is all about Blanking something with no examples of tapping it (so far), and its hemalurgic power is all about blocking All Powers at once by the same general virtue of Investiture not playing well with Aluminum present in the equation, especially if spliced directly and realmically into the spiritweb.

For what it's worth, Isles of Emberdark looks ready to give us a more detailed look at the dragon life cycle, if the preview chapters are any indication, so we should know more soon on the Dragon side of the question when that get's published. If you're interested and dont mind that kind of spoiler you should check those chapters out.

Just to a bit clarify further: Savantism comes from over-use Warping the Spirtweb (and doylistically will always have a downside). Resonances are when the energies of two Powers interact in weird ways to create effects that are related (thought not obviously so) but generally distinct, like Windrunners getting more squires in a weird Spiritual Twist on Gravity+Adhesion, or Lightweaver Memory in a weird Cognitive Twist of Lightweaving+Soulcasting. And then there's just good tactical/synergistic use of two powers together, like weight+Pushing making you hit way harder, or F-Tin protecting you against A-Tin's downsides. There are also some things that were once described as Savantism but now are being called Just Skill, which I believe is where Wax's bubble push currently is.

More than a decade, less than 300-ish years that is the earliest they could have been founded at all.

Sorry, you lost me. Can you elaborate?

I think it's an arms race to solve opposite limitations of their magic systems. Roshar has stronger Powers but relies on naturally occurring sources of Investiture in the Physical Realm in the form of either Perpendicularities or a very Finite number of Godspren-empowered Bonsmiths. But they have Rosharan Fabrial tech developing that is likely on the way to solving that sort of problem. Every Allomancer has the ability to pull Investiture from the Spiritual Realm directly in relatively large quantities, but the actual applications of their Powers (currently appear to be) more Limited, and you generally need to be born with the powers. Scadrian Fabiral tech is already well on it's way to allowing anyone to use the powers, though we dont yet know all the details and limitations of creating or using them. Rosharns have lots of Power and versatility but rely heavily on Investiture Supply Lines. Scadrians have to work harder (or be luckier by birth) to get specific Powers and/or effects can get to their Investiture source from anywhere in the Cosmere.

Having just watched the Death Stranding 2 trailer, I thought this would be a whole other conversation. The polarized Light bit caught my attention. But lets back up for a sec, what do we know about Fain life that is Canon? Im counting recent WOB's that he seems committed to but really just not the explicitly non-canon prime stories. Yolen had both ecosystems Fain is an Invasive Ecosystem Fain life is characterized by 6 limbs. Dragons are of Both? (per info in the Isles of Emberdark preview) The Fain Ecosystem is Colorless. [Non-plot related WoT reference] So that's where Im at, I've always been fascinated but confused by the role of Color in the broader Realmics and Investiture, from how the Dawnshards cause a Vibrancy aura just like Breaths to how some plants in Shadesmar are occasionally full color while most are greyscale. Also the role Color-drain plays in Awakening, since it's not the investiture Key (like metal or Aon shapes) but also not the source of investiture itself. Sooo... Any thoughts?

My understanding of Miles Pain issue was that it was Savantism from overusing Gold at full allomantic levels. But Savantism has and/or is likely to be retconned per WOB, so it's a bit of a moving target to draw the line between the two. I was referring to how they've more recently learned to store their Sense of Pain in tinmind to suppress their pain response. If eventually can similarly store specific physical Traits in a Pewtermind, rather than just physical bulk the way Sazed did it, they might be able to start playing with storing and manipulating much more targeted traits (both natural ones and things A-Pewter grants).

Can we talk for a moment about the possibilities (if any) of Twin Pewter? This WOB implies that Pewter could actually be activating a Mind-Ove-Matter state with potential for larger changes akin to Returned. And in general Feruchemy seems to be developing where metals have more and more variety of use and application than Era1 realized, as an overall trend (storing Pain in Tin, pretty much all the spiritual metals, etc). So Im wondering if there are any benefits to using them together, either in traditional Compounding to get the Feruchemical version of Strength, or some more specific benefit to selective storing the way A-tin and F-Tin work together well. Or Both, if you can use the A-Pewter's Mind-over-matter state to modify more specific/focused physical Changes. So for example, I wonder if F-Pewter could target just Height, or just Physical Endurance, and then store that alone in a Pewtermind (at which point you could Compound it for more if you wanted).
