As you say, we see one of these spiking scenes from Marsh's viewpoint and not only was he acting on Ruin's orders to spike someone, he had Ruin literally guiding his aim to hit the right bindpoint. Odium would have to have been doing something similar to Moash if he was actually doing hemalurgy and there's absolutely no indication in the text that it's happening, nor is there any reason for us to think that Odium knows enough about hemalurgy to provide the necessary guidance anyways. Brandon has said that Moash's knife is 'similar' to hemalurgy but it's not the same thing. The dagger itself is probably Odium's godmetal ('Rayseium' or something like that) since it doesn't look like any of the other known godmetals but the faint golden color does fit with how Rayse presents himself both to Dalinar and to the Singers and requires far fewer assumptions than Odium somehow getting his hands on godmetal from other planets. Since we're looking at something similar to but not identical to hemalurgy, whatever Moash did probably doesn't have the same requirements as hemalurgy and just killing Jezrien with the knife was enough to do the trick.

Welcome to the Shard! One comment on Hoid, we don't know that he's actually able to perform Sand Mastery, we just know that he has some sand. Brandon has mentioned that even if you can't Master it, the stuff makes for a handy sort of Investiture Radar because it will react to any 'kinetic' Investiture used in its vicinity. As @RShara said, there really hasn't been much multi-world magic actually seen other than Hoid, in the sense of a character having direct access to multiple systems and using them in combination. Brandon has said that he thinks he's included at least one instance of hemalurgy being used off Scadrail but it's not meant to be noticeable, but that would potentially count if our mystery spiked person also had access to a non-Scadrian magic system. Brandon has confirmed it outside the books. Vasher has tried using Stormlight to Awaken but hasn't worked it out yet, but he's able to survive off it just fine in place of consuming the usual Breath per week. It's actually why he chose to go to Roshar in the first place, because it's much easier and less distasteful to get Investiture to feed his Divine Breath there. Brandon confirmed (again outside the books) that the man in the lighthouse is the hoed who shows Raoden and the others the way to the pool above Elantris and is then placed in it. Somehow he survived the transition to the Cognitive Realm and he wound up joining the Ire. It's possible they had a hand in his survival. There are a couple visual clues to his identity, the bald head, the fact that Kaladin thinks he looks really old and the fact that he 'looks Shin' which is a pretty good indication of a worldhopper who's not trying very hard to blend in. His name's also very Aonic-sounding. And then there's the real big hint: He swears by 'Merciful Domi' when he realizes Kaladin is a Surgebinder. Yes, but that means that he's got a bit of Odium's Investiture mixed in with what he's doing, so it's a combination of magic that's not 'natural', even if it's magic from the same planetary system rather than entirely different worlds. Brandon confirmed that Renarin's got some Voidbinding ability which is likely (but not confirmed) to be related to his apparent inability to use Illumination. We know that the metal comes from a Shard and it's one that we already know about, and 'Trell' and this Shard are one and the same. The most common theory and the one best supported by the evidence is that the metal comes from Autonomy.

Yes, it would be possible. As mentioned we've seen atium bracers that Rashek wore and atium spikes are invaluable for hemalurgy so it can be melted and cast into different shapes, or alloyed with other allomantic metals even if we only know of malatium right now. So yes, it would be possible to make an atium sword if you got enough beads. However, we don't know of its properties like ductility, malleability or hardness so we can't say whether it would be any use in weapons or armor and we definitely know that using it that way would be a fanastic waste given how powerful it is in the Metallic Arts. Plus, you'd need so much atium to make even a small sword that it's not even funny. As mentioned, atium is Ruin's Investiture condensed into solid form. This same Investiture in gaseous form is the 'dark' mists that are occasionally seen, which continue to exist post-Catacendre. And the black pool that Alendi writes about in his journal was Ruin's Perpendicularity, the liquid form of the Investiture. So far as we can tell, it didn't have any special power or function, it just allowed Realmic transition like any Perpendicularity. However, molten atium is not the same as the liquid in the Perpendicularity and gaseous atium is not the same as Ruin's mists, so the three forms of condensed Investiture should be seen as separate manifestations rather than a single manifestation in three states. Liquid or gaseous atium would function the same as solid atium Realmatically, except that it would be extremely dangerous to try burning in those states. We can infer this because we know that molten metal can be used in feruchemy, with the same caveats..The metal doesn't gain new effects just because it's undergone a phase transition. Related WoB:

Well, there were three sapient races on Yolen and none of them were bunnies so no, no Bunny Shard. But for all we know, one of the original Vessels could have a thing for them and have made a planet with uplifted rabbits just because they could. We know there's at least one inhabited planet (not Braize) that has no humans so hey, until proven otherwise it might as well be Bunny Planet. Or possibly Crab Planet.

There's nothing I can do about it one way or another so no, I don't bother worrying about it at all.

Liquid-state Investiture is the most potent. Given that Brandon says that the form of the Investiture is critical, I don't think that liquid Investiture will do the same sort of things that it can do in solid or gaseous form. The Well of Ascension was specifically set up to do one specific thing (which didn't entail swallowing it) but that doesn't mean that other Perpendicularities would do similar things. Given how potent it is, I wouldn't be surprised if trying to drink the liquid did Really Bad Things to you. Following that WoB, drinking out of the Well won't make you a mistborn. There's another that Devotion's Perpendicularity works differently from Preservation's so there's no reason to think drinking from it would make you Elantrian (by the way, the Dor is the same everywhere and is a mix of Devotion and Dominion, so there's nowhere that doesn't have at least some of both) and since humans can't gain Aviar talents there's definitely no point in trying to drink from Patji's Eye.

Welcome to the Shard! While I think that yes, he probably could break a Shardblade if you gave him one, I think there's an important qualifier to that: Whether it would be funnier for him to succeed or fail under the specific circumstances involved.

Wax had the Bands of Mourning, he literally was a Full Feruchemist at the time he inspected the statue. Since his A-Steel trick to detect whether a bit of metal is a metalmind would be useless on aluminum, the only way he could have tested the aluminum on the statue (and thus the only way that line makes sense) is if he did it while holding the Bands and thus had the full slate of feruchemical abilities that would let him detect if the metal was an aluminummind.

Bear in mind that feruchemists can sense when a metalmind has a charge even if they can't use it themselves. When Vin tries burning one of Sazed's metalminds as an experiment, he recognizes her description of what the metal 'feels' like because it's the same thing that he feels when holding a metalmind filled with another feruchemist's charge. All that Wax would need to do to test if the aluminum on the statue is a metalmind is to hold the Bands and then touch the aluminum while thinking that it might be a metalmind, and he'd be able to know whether it's got any charge or not. In fact, the only way that Wax checking the aluminum makes any sense is if he did it while holding the Bands. He can't even detect aluminum much less Push it so doing his 'steelsight test' like he did to figure that the gold bracelet was carrying a charge wouldn't have accomplished anything.

We know that a bullet can be used to create a hemalurgic spike. You need the Intent to create a spike when you're firing it and you need the usual combination of right placement and right metal but the fact that you're firing it from a gun doesn't make any difference.

Domi is derived from Aon Omi, which means Love. That it sounds like the beginning of Dominion is just a coincidence.

We know Scadrial has bunnies (which means Yolen does as well) since Wayne is reading a story that's clearly modeled after Watership Down during Bands of Mourning and asks VenDell if he could become a bunny.

This is easy: Either Khriss or Hoid because then I'd Know Things, the likes of which I'd give an arm or a leg to know right now. xD Setting named characters aside, being a member of the in-universe Seventeenth Shard or a scholar in Silverlight would be awesome. When you're a Vessel, you really don't get a choice. There's some wiggle-room to interpret the intent of a Shard but you can't get away from the essence of it. And if you're not well-matched with the Shard, you'll get twisted by the intent far worse than if you were. See what happened to Ati compared to how well Rayse is coping with being the embodiment of divine hatred.

Yeah, A-Bronze detects kinetic Investiture so it's not going to do a thing for a metal that's not currently being burned, even a godmetal that literally is Investiture in solid form. Here's WoB on how it works. If A-Bronze could 'sense' all Investiture whether kinetic or potential then the Steel Inquisitors wouldn't have had any problem finding feruchemists because Invested metalminds would be like blinking neon signs saying 'Here I am!'.

I don't think Kaza actually knew anything herself, she was killed because she could have learned things and the Aimian didn't explain their actions further because Team Odium might have found out what that conversation would have revealed and that would have been Bad.

Kelsier! Oh wait... Since my first actual choice has already been mentioned repeatedly (Elhokar) I'm going to pick someone else and say Karata. She did everything possible to help the children of post-Reod Elantris, she really just wanted to see her daughter again and she was just on the edge of becoming a 'true' Elantrian but she died protecting Raoden before he could finish fixing the Aon. Denied the possibility of a happy ending by thiiiis much.

Brandon has clarified what Khriss said in Arcanum Unbounded. He targeted Ambition first because he saw her as the biggest threat but he didn't find her until after killing D&D.

Responding to the general question, it's possible (but difficult) for most spren to form 'complex structures' but there are limits to what they can become and they still have to be one piece. Making anything with two or more separate pieces requires splitting the soul of the spren and they really wouldn't like that. This means that even if you could get a working Shardgun in a single piece, the bullets would have to be separate (and thus have none of the magical advantages of a Shard-weapon) or you'd need to make the spren the projectile and then you'd need a fully working gun, in which case you might as well just make those for normal people let the spren do something more interesting. Shard-chakrams for example, which would be a hell of a lot more effective at killing things than a Shardbullet given how the Spiritual damage works. Do you have a source for this one? I know he's mentioned (paraphrased) that things will get interesting when Lightweavers figure out enough science to learn how to make lasers but not that they could be weaponized in fabrial form. Though that would get pretty crazy and I can definitely see something like that happening by the time we hit Mistborn Era 4. On the other hand, a fabrial that can replicate a Basic Lashing is pretty much a magical railgun, which seems like it would be easier to make and potentially much more devastating, especially against something like a thunderclast.

This isn't very likely, as Khriss mentions in Arcanum Unbounded that there are lots of iinhabited worlds in the Cosmere that aren't host to a Shard. We know of enough 'spare' worlds right now that you could distribute the paired Shards up between them with room to spare. We've got a whopping three inhabited worlds (plus one more habitable one) in the Drominad System which is enough planetary real estate to house all these Shards in and of itself. Or two-thirds of them if you only count worlds with sapient life and decide that First of the Sun currently having an Avatar of Autonomy makes it off-limits. Then there's Obrodai which certainly didn't have any Avatars until recently, so it would have been 'empty' yet life-bearing when the Shards left Yolen. Then there's one other habitable (but not terribly hospitable) world in the Selish System and two in the Threnodite System. And those are just the worlds we know of. The way Khriss frames her discussion of what makes First of the Sun so interesting makes it clear that there's lots more we don't know of and most of which we likely never will. Oh, and there's at least one inhabited world with no humans other than Braize. So plenty of room for the Shards to spread out, meaning that there's no real need for them to have teamed up due to a lack of individual worlds to Invest in. In retrospect, I don't think that he's claiming to be the creator of humanity but he's claiming that he's the entity that Vorinism says is the creator of humanity. The exact words he used were "I am... I was... God. The one you call the Almighty, the creator of mankind.". The key here is 'the one you call', with the whole creator bit following directly from that rather than being an independent claim.

Welcome to the Shard! To add to what Ripheus23 and RShara have said, Odium killed Aona and Skai first and he shoved the power of Devotion and Dominion into the Cognitive Realm because he had a particular goal in mind (keeping anyone else from being able to easily take up the Shards) but he didn't know the side effects it would have and didn't have any opportunities to test it out beforehand. What he did with Ambition and Honor was different due to his having more experience and thus a better idea of how to accomplish his goals, and the situations with those two Shards differ from each other as well in various ways. At the point that Odium showed up in the Rosharan System, Honor and Cultivation had already Invested in Roshar so they'd have the same problem leaving the system that Odium does right now: Lots of the Shard's power is 'in the world' and can't be easily withdrawn so Honor would either have needed to take steps to deal with that or he'd have to leave it behind. So, less that he didn't have a chance to run away and more that he wasn't willing to make the sacrifices that running would have demanded, vis a vis abandoning the planet (and possibly Cultivation if she didn't join him) to Odium or sacrificing a hefty chunk of his power. Given what Honor (apparently) represents it might also have been flat-out impossible for him to flee even if he really really wanted to, since Shards are all bound by their oaths and he's extra-bound by his specific intent.

I submit to you that Captain (thank you very much!) Jack Sparrow has Plot Detection Senses and always knows where he needs to be, like so many characters in films and books. Which is pretty much how Hoid's power works, it's just that Brandon has formalized and justified it. You mean like jumping off falling blocks of stone in the last movie? Yeah, he's got to be using Basic Lashings there. xD And the secret of 'bullet time' in the Matrix movies is that everyone has A-Bendalloy.

I wouldn't hold my breath if I were you. There's no way he's going to give a definitive answer on something this big outside of the books themselves and Dragonsteel is a long way off.

Yes, aluminum is consumed when it's burned and it burns quickly. When you burn it, you wipe all your metal reserves. Or at least, it seems that way, if you had a very large amount of metal in you and a smaller piece of aluminum the latter might burn away before it's finished working on your other metals.

I don't think so. The 'ability' comes from the spike and it's been described as something stapled onto your spiritweb, so once the spike is removed there's nothing there on your spiritweb to be healed, just the original template. Now, the purely Physical manifestations of having a removed spike (ie, the hole in your body) would be healed, but that's sort of a separate issue. You mean like the hypothetical person who survives being a hemalurgic donor? Kind of hard to say since we know practically nothing about them other than nobody knows how to do that right now and if it could be done, the victim would be worse than a Drab. It might be similar to what we see in Stormlight Archive: But as far as the damage to the spiritweb itself, the 'worse than a Drab' thing sounds like it's doing far more damage to the soul than just taking away the bit that says 'you're an allomancer with A-Steel' or whatever it is the spike steals, since that would leave you at the 'baseline human' level and we know that's not the same as being a Drab. Actually, the fact that Sazed could heal Spook tells us that there's got to be some record of what your spiritweb looked like in the past (an earlier code revision, let's say) that could be reverted to. But since humans perceive time moving in a linear fashion, they don't have the means to access these previous versions of the spiritweb. Sazed with his much greater ability to perceive the Spiritual Realm could do what an ordinary human, even a highly Invested one, couldn't. As for Forgery and Soulcasting... well, in the latter case the most common uses are to change one thing into a pure essence. I'd imagine that what happens is that you'd look at the parts of the code that say 'these are your bones and composed of this, these are your muscles and composed of that, etc.' and replace all of that code with whatever the Essence is. So, you get the criminal whose soul suddenly tells him that he's actually made entirely of quartz, or the Wind's Pleasure suddenly getting all of its code for the wood, caulk, rigging, fastenings, sails and everything else suddenly changed to 'water'. Forgery is like hemalurgy in that your original code is still there, it's just gotten something added to it on a non-permanent basis. In the case of living things, maybe the best analogy would be that the Soulstamp is like a virus that tricks you into running modified code (whatever the stamp is programmed for) until such time as the antivirus software is able to remove the virus, at which point the Soulstamp fails. More plausible stamps would be like a better-programmed virus that takes longer to detect. The analogy kind of falls apart since there are stamps that can persist indefinitely for inanimate objects but even the best stamp will only last a day or so on a human, but it's close enough I think.

Let me try a programming analogy and say that your spiritweb is a computer program. When your spiritweb is damaged (say, because some Shardbearer took a swing at your left arm) the damaged portion is like code that's been commented out. The code that tells you how your arm works is still there, it's just not currently on speaking terms with the rest of your spiritweb. Healing then fixes this damage by repairing the block that keeps the rest of your spiritweb from interacting with the damaged portion, like a programmer removing the comment and allowing the code to be run again. With savantism however what's happening is that the underlying code is being rewritten so that it's no longer the same as what it used to be. Therefore the healing doesn't do anything because there's no 'damage' to repair as far as it's concerned. Does that help any?
