IIRC, it was never said if Szeth heard screaming. Since it was never commented on, I doubt it happened. Kaladin definitely didn't hear screaming either when he held it. What indication is there that Taln has abandoned the Oathpact? It seems more likely that he's still with it considering he's trying to warn the people to get ready so that they can survive the True Desolation, to the best of his abilities.

Sprenblades are made from solidified investiture of spren, whatever that is, we don't really know for sure, but most spren are a mix of Honor and Cultivation's investiture so the metal is probably of both of their investiture. Honorblades are probably made from the solidified investiture of Honor directly. As such, they're both more than likely unique metals and would be allomantically inert. Also, in any case, even if they are an allomantic metal, they're extremely invested so it would be hard to burn them, to the point of allomantic inertness.

You can compound with hemalurgically gained allomancy and feruchemy abilities. The hemalurgically-gained abilities become coded by a mix of both your identity and the victim's identity, allowing you to access metalminds made by either. In any case, if inquisitors couldn't compound, then Marsh wouldn't have been able to live 3 centuries by compounding atium. So far, all we've seen of nicrosil feruchemy is that it can only store the ability to use a manifestation of investiture. Personally, I don't think it is possible to store other parts of innate investiture since other forms of feruchemy store those. In any case, even if you store the a hemalurgically-gained manifestation of investiture, when you compound the nicrosilmind charge with allomancy, it would be the power of Preservation mimicking the power the feruchemical charge would give, so there wouldn't actually be any weird problems. Also, I don't think the hemarlugic charges are necessarily of Ruin's investiture, more likely direct pieces of the victim's innate investiture. In any case though, a Nicroburst/Soulbearer twinborn has the potential to be incredibly powerful, with or without hemalurgy. All they would need is to get a hold of a medallion and they would be able to indefinitely possesses the abilities the nicrosilmind of the medallion holds, providing they're careful and don't allow a charge to run out. They could, with a bit of effort, become as powerful as TLR, and possibly more so, though with stricter limitations and a dependence on nicrosil.

Skybreakers or Stonewards? Skywards isn't an order. One didn't betray according to an epigraph in WoR.

All the steelrunner would have to do is hold a knife or a sharpened wooden stake and run at him. Right before hitting him, they let go of the piece of wood, sharp end facing him and run around him. The momentum of the stick would probably be enough to go through him. A glass knife would work as well.

The problem I see with that thought though is that Yata specifically defined the question as being about the "perks" of the interaction of two powers, and since Brandon is more than likely aware that the two is different, it seems unlikely that he would confuse the two. Also, the fact that he uses the term "mechanics" to explain why those with many powers don't have the lesser perks seems like an indication that he isn't referring to the fact that a misting would just specialize better at their one power versus a mistborn being a proficient at all of them, but more so that there are some underlying rules of how powers work together along with the makeup of innate investiture which would prevent the tangential perks from appearing. I'm using the term tangential to describe the fact that the perks aren't an amplification of a part of one of the powers, but rather something that is only possibly present with both powers.

I believe it was said that brute metalminds at least aren't full bracers, but rather open bands which go around the arm and which can bend with the muscle expansion. Nonetheless, there would definitely be limits, though IIRC, Sazed tapped a fair amount in WoA and grew a fair bit without any problem. The stretchy suit would be an interesting idea. It would be tricky to have it setup so the pewter is always touching the skin, while still keeping it stretchy.

Could you elaborate on how that annotation exemplifies that the enhanced abilities of a savant and the perk of someone with two powers as meaning the same thing? I assume you're talking about the section at the end which talks about Wax being a steel savant. Also, it seems fairly obvious why no distinction was made. There was no need for one since the concept of savantism hadn't even come up in the question. Could you also explain why you think the two are the same? Just a thought, for anyone who doesn't have a copy of SoS or BoM to view the passage we're discussing:

They're made from investiture, like everything else, but they don't contain investiture, which is what would make them resistant. While they are more than likely made from more investiture than most other metals, it isn't that significant a factor.

Yes, Warbreaker spoiler.

You don't get two souls when a person is cut spiritually. Only the main spiritual piece remains connected to the physical while the other spiritual pieces is destroyed, as examplified by the body going grey. [Source]

No, they cut through the soul/spiritual and physical. Only Nightblood, as we've seen so far, can cut through cognitive as well.

True, I didn't think of it as a perk, but I've always found the scene at the end of AoL to be a bit extreme, where he intentionally deflects a bullet off of another bullet. The insane accuracy, as you put it, being a perk would make sense.

@Yata Good catch on the WoB. I've been wondering that for awhile, before even Oversleep posted. It has been stated in the Ars Arcanums for SoS and BoM that, according to the writing, possessing more than one "power", or ability to use a manifestation of investiture, results in the formation of an unique effect for each intersection of powers. These are the "perks" that Yata was asking about, as he defined more accurately in his question. You can compare surgebinding to allomancy and feruchemy in this regard because they are all manifestations of investiture. Just because we haven't seen any obvious sign of perks from the Twinborns isn't saying much. Also, don't forget we're getting the PoV from these characters, so whether they are doing something which is beyond what is normal for their powers wouldn't be obvious. For all we know, Wayne's ability to mimic personalities might be a perk of his power. Probably not, but still possible. For the most part, we know of the KRs perks because they were explicitly mentioned. If we had been shown it happening a lot, we might've not clued into the specific perks as easily. The Lightweavers' and Skybreakers' described perks could be naturally-gained quality. However,with the Windrunners, you cannot really say they creating an excessive amount of squires is natural. Also, we have a WoB that does state that those abilities have supernatural ties in their origin.

Fair support to a theory that at least one original shareholder. However, since it isn't fact you probably shouldn't state it as such. I do agree that chances are very good that at least 1 was a dragon.

There are still limits, and I'm fairly certain steel feruchemy can go well beyond that. Besides, I still addressed the fact that Kelsier wouldn't be burning atium in advance, unless of course he was aware that the keep had a steel compounder.

They're just invested, with someone's innate investiture. Interestingly enough, I've actually found the whole "counting through non-living things on the first time" trait of sprenblades kind of odd since all objects have a spiritual aspect, so I wonder why sprenblades only cut through the spiritual of living things. [Mistborn in spoiler]

Steel compounders build a hugely charged metalmind then go out and one-shot Kelsier at such a high speed that he doesn't notice is what I presume the plan is. Since you can compound steel enough that you're moving well faster than people are aware, I'm fairly sure one could move faster than even Kelsier could well notice, even with tin. The only defense Kelsier really could have is if he were burning atium, but since he wouldn't start burning atium until he engaged another mistborn, he wouldn't be prepared in advance. Also, I'm doubtful of atium even helping against a steelrunner with enough of a charge since the reaction time and physical movement time would still be well too slow.

Interesting idea, except for the huge flaw in that there were no twinborns during the time of the Final Empire. Feruchemy isn't even known either for the most part. So the idea doesn't match the setting at all.

Yes to the above, though the last two wouldn't be completely effortless, though fairly so since their charge would be pretty negligible. With shardblades, the only limiting factor is how invested the object they are cutting is. In other words, more or less, the resistance of an object to a shardblade is proportional to how invested it is.

Spoilers guys, please, as Argel said.

WoB that non-Nalthians with breath can use biochroma (breath), and I'm assuming by the question, awaken. It is interesting that the person said BioChroma instead of Awakening, so it's possible that the question just meant that they could give the breath away without awakening as well as gain the heightening perks. I feel like there's another WoB which more directly says so, but I can't remember its details and I can't find it. There was a WoB where he did say "if a non-Nalthian gained the ability to awaken", so you may in fact be correct. I don't think IVs have bindpoints, unless it's a living entity. In any case, a precept of hemalurgy is that the spike has to touch blood in order to take or bind a charge so I'm not sure how you would make that work with non-biological and living Type IV entities.

Lerasium has only been confirmed to have a spritual side effect. We don't actually know what its actual allomantic power is, just that it can turn people into allomancers as a side effect. Nonetheless, I think this is a good idea. The thing is, atium allomancy isn't drawing power from investiture in the metal, it's drawing power from the investiture which is solidified into the metal. This power is released when atium is burned. As such, I don't think lerasium hemalurgy would draw any power from the lerasium making up the spike, as that would require the physical metal to be converted back into investiture, which I don't see happening naturally. Also, I don't think hemalurgy requires an outside source of investiture to occur, unlike allomancy. Copper steal intelligence and memory according to the coppermind, but I have a feeling that that is sourced from MAG which may not be entirely accurate. I suppose the capacity for sapience is a bit different, but not really I think, not enough to be an entirely different metal. I'm thinking more of a possibility would be that lerasium steals connection, something which could be fairly powerful in the right hands.

Erm. Unless I've gotten bad at counting and reading, I asked for 12 names and you only gave 11. Also, Grey Boy.
