@StanLemon In real world, silicon one of the Nicrosil's component were discovered in the 1907. Of course this isn't a prove but you realize how far was to make it. Then the problem remains if those metals were around, why nobody seemed to use them or find them anywhere? Much more in the stomach or the person of the supposed users.? To be completely honest, the TLR's "rebuilding himself with the Well" invalidated the need of a reverse compounding for his feats. We were truly searching for a mechanism because we compared him to elend in the past, but that comparison has no sense as the TLR was far stronger to start with

The Spike hypotesis would imply a lot more Preservation (and still a mostly meaningless amount) than Ruin (assuming there is some Ruin investiture in a Spike at all) in Nightblood. Probably the most likely scenatio is the one @Calderis proposes from some time... A local pack of Ruin's Investiture hanged out on Nalthis was tapped by Nightblood's nascent soul thanks to his Ruin-aligned Command.

Like Cal said the Recreance was the result of multiple factors: - They re-discovered they were the Invasors and their enemies are the descendants of the Roshar's natives. - They discovered the magic (associated with their Surgebinding) destroyed the mankind's homeland and once done they conquered another planet. - The god they followed instead of mitigating this fears and doubts.... Enchanced them stating they will destroy Roshar too. - They (or the Heralds using Surgebinding) shattered the Shattered Plains, an explic demostration of the danger in the power wield by them - They lobomized a whole species All this stuffs were the Recreance's seed and once a strong doubt arose in them, the decision to break their Oaths was just a matter of time. Much more if you consider the Desolations were over and the menace of future ones was gone too.

Also if thematically they are the same, there is a difference between Amaram and Denth's cases. Denth denied the redemption for pure guilt, Amaram refused redemption also for external factors... He is bonded at that point with a Voidspren and litherally linked to Odium. Indeed he explicity stated "He would not let me" (or something like that). Maybe a full self Amaram would accept Dalinar's offer

Yeah, we are talking of Vin that upon discovering Aluminium was truly fast to try to find the alloy of that. And the same group that later discovered Electrum (thanks to TLR). They will be very cautious to every kind of unknown Metal. Without considering the Nicrosil or any other weird metal wasn't in the most likely place if Rashek used it ... TLR's stomach

The Skin isn't required at all, simply Human ripping off the Spikes ripped also some skin that as you pointed in the OP isn't really too strongly attached to the Koloss

Indeed Fuzz was a pawn of Preservation's plan like everyone Preservation considered/predicted the damages trapping Ruin will cause him like he predicted everything else. His damaged version was a part like the rest, as also he predicted Rashek's decision to suppress the knowledge of some metals (by the way also without Rashek all the 16 mundane Allomantic metals can't be discovered during the Era1)

Indeed we don't know if F-Nicrosil is needed. If that level of power is possible (and F-Nicrosil shows this) in theory you could obtain it inany way. Rebuilding your spirit is not an impossible option, as also keep stacking spikes (stupid example, imagine an Inquisitor build only mostly with A-steel spikes). By the way, among the metals unknown in era 1, Niscosil is the One we could be sure it can't be produced without advanced tech as it requires other materials impossible to craft with their tech. There is also the already discussed arguments of no new metal be discovered on TLR, in his palace or anywhere else.

A possible option is that the assassin attacked with a normal weapon and Rock was luckly enough to survive, then he kept killing until someone's death spawn the Honorblade... then he used that. By the way, there isn't even the need of him killing someone to get the Blade, if the Bridgeman who held it...simply summoned as response to the attack. Of course also @Calderis 's option of multiple attackers has merit and it's probably more plausible

Honestly the "closer to the CR so he is stronger and differently affected by Shardblades" have no sense. We saw a good amount of beings with different degrees of Connection to the CR (Radiants, Singers, Lift, Cognitive Shadows and spren themself)... All of those don't have special behaviour with Shardblades. They all have a Soul targettable and everyone of those is Spiritual wounded by bein hitted by a Blade). About his strenght, I think his size and muscle mass is enough for the feat. It's like The Rock (Dwayne Johnson) XD. A bit taller than Kal (that is tall for Alethi's standard) and twice as large.

Actually there isn't a truly difference in what TLR and Vin did. Simply Rashek had access to a drop in the ocean of the Shard's power that once expended (or leaked away) it returned to the system. Dalinar's case is weird and I agree but mostly we don't what he did. As far as we know it could be a scaled down version of what rashek did. A "moment of deity" he used to performe the Realm bending thing. As I said for how I see the Ascension, all the instances proposed made sense in the broader phenomen, but surelly others could think otherwise. By the way, I have to check again Odium's words but it's possible that Dalinar didn't actually Ascended but that Odium witnessing the stuff Dalinar performed, could have deducted that Dalinar is capable of Ascending.

Kal isn't an expert in Shardbow, I doubt he even tried to use one or neither inform in those. He knows only the common knowledge about those. The common knowledge is mostly a single sentence: "A man without Plate can't use them" He mixed this with his own experience with Stormlight and he deduced that a Radiant without a plate can't use a Shardbow... This could be true or false, Kaladin's statement isn't an expert statement. Rock is truly strong of his own, the Stormlight allows him to heal and a scenario of histerical strenght (if I don't remember wrong it's called technically Maxi Maximori Strenght) from him could easily allow to performe such a feat without suffer an heavy drawback. Also in real world there are instances of superhuman feats when the brain for some reason decides to lessen the limitation imposed to the body, it could be the same for Rock... Also if I don't even think it's necessary.

By the way, the Sibling was slumbering and retiring from mankind before the Melishi's plan and the Recreance

Doctor Manhattan's body is just something a bit more than a puppet. Something that could be annihilate and remakes at will without any issue... Returning to the actual point. I don't see the need of multiple terms, Ascension seems to be referred to a specific scenario with requirements. And this doesn't matter in how hard those requirements, imagine if the requirement is "going supersonic", it will not matter if you go a bit faster than Mack 1, at Mack 3 or lightspeed. You regardless are ok with the requirement. Similarly the Ascension requires only to have access to a X amount of Investiture. That investiture associated to the status you reach will have Y effects and will result to the Z consequences for the guy. This regardless if the Investiture you accessed was enough only to performe Y for seconds/minutes (TLR) or forever (Shards). Of course, we could talk endless of the Ascension at this point. We know nothing about... I have my own model like probably everyone has his own. Maybe I am right and maybe wrong but I can't say Brandon are using the wrong terminology if he didn't even explained the meaning behind yet

We are not even sure if there is something magical or Realms related to the Evil. It could be a completely mundane event/stuff, like a pestilence or a social change or a cultural revolution that pushes some people to flee from the Homeland. It would be not too different from the puritans who fled from the Europe to America.

There are not Dark Seons... Those are simply the Skaze

There are other Blades' origins that Brandon RAFOed before, for example the Elokhar's one (that Cal already posted) and it's misterius 10 Glyphs

Rock is confirmed to not be a Radiant but merely a Squire. The simple prove of that is him mostly dying unable to heal in Urithiru far from Kal and recover his Surgebinding only after he was moved to thaylen city. About his ability to use a shardbow, I assume it's only his own phenomenal physical strength helped by Stormlight

@Quantus I think you are mixing the Skaze and the Svrakiss together. the firsts are the well known Splinter of Dominion and analogue to the Devotion's Seon. They are truly influent in the Fjordel empire. The Svrakiss instead are part of the Fjordel folklore and they are the enemies of their god.

It's not truly the paper currency we have habit with. But if you read again Rysn Interlude in OB and her teacher's explaination. You may notice that is the actually basic working of paper currency. Paper stuffs that rappresent the ownership of something valuable stored in a safe place (in this case, gemstones)

He also swared the first Oath to the Spren. By the way.

There is already paper currency, simply the Alethi don't use it. It's what we saw the Thaylen already do, the whole bank exposition showed us how they manage money beyond pocket money

Like other said, regardless of Nightblood's mantra. He has no idea of what the "Evil" is and indeed he simply try to apply this etiquette to everything he could to then destroy it. In the end, most of Nightblood's judgement comes from the self awareness of the ones he judges and using some very meh criterias. I will be not surprised to see some "evil jerk" holding Nightblood and slaughtering "innocients people"

It's not impossible... but why did he have any reason for doing that ? It's just a potential menace without a truly benefit. The only instances where the TLR would advantage of using Cadmius is on himself to spare Atium... and he didn't. Chromium is still more unlikely, as the books shown evidences of Mistborn-based Inquisitors to not having Chromium avaliable.
