Like @anna said, Mistborn Era2 took place in the middle of Stormlight Archive (not exactly sure if between 5-6,6-7) and between the Era 1 and Era 2 passes 341 years. This means Stormlight Archive is roughly 300 years after Mistborn Era1

We don't know, but I believe the stormfather need to wait for the Stormlight to stack over a certain treeshold to summon a new Highstorm. When he did this in WoR, they were in the middle of the Weeping and the Stormlight on ROshar was mainly returned to the Spiritual so it was avaliable to be released again in the physical realm

Eyepatch+ hat could help but it's not a great camufage.

First of all, it's not easy to burn a Spike as like for the Metalmind you need the Spike's Identity to match the allomancer's one to burn. Anyway the splicing of sDNA could honestly gives every kinds of effects. One could gain a degree of the attribute in the Spike but honestly every weirdness could happen.

Do you realize that Elend wasn't fighting alone right? And he Ned to both maximize his killing rate and the allies' survive rate. There is no actual sense in not using other metals, expecially the One that burns slowly. And as I said before, the simple fact Elend runned out of metals that Will last hours...means he used them for hours.

Assuming the Atium gives you a Perfect view of the next seconds and the best action to take. Be' stronger and Faster means you could use those nexts second to influence a wider area and in a Better way. If in those 2 seconds you could move farther (both thanks to Pewter or for Steel/Iron) your options rise and this allows you (and the Atium) to pick something you could not performe usually.

It's not impossibile but It's really unlikely. First of all Kelsier has problems to leave Scadrial for his status. But this is something that can be' solved with the right technique (that I don't know). But Kelsier has a "no-sense look" with a Spike into his Skull. It's not something Brandon could simply Place without context.

TLR could be a special case, as he could use his Feruchemy to store some of the Informations or change himself with the Power to be' able to retain them

The problem like others said, It's your definition is wrong. For example, someone could say that Feruchemy is "store Investiture into a Metal object that could be retrived later" but this doesn't mean storing Breath in a Metal object is Feruchemy.

Could be that and could be simple a way to protect her exposed arm from counterattacks

Hoid jokes about his one-armed but he doesn't see himself as a one-arm. He never accept the arm's lost...don't mix know something and accept something. Hobber's change is not due the Healing itself. Kal pushed him in want to be whole again, he pushed Hobber to change in the Cognitive and once he did that. The first surge of Healing fixed him...but that will happen regardless of the Healing's source. By the way we know by WoB and WoR's scene that Regrowth could heal a Spiritual damage quite fine. Probably there is some efficiency difference between the Stormlight's Healing and Regrowth (and Regrowth by description is superior in this) but not in what those Healing could heal

Except for Lerasium and its alloy, you need the right Spiritual Marker to performe Allomancy so a Raysium or Tanavastium will be useless to a guy who wanted to burn them allomantically. Harmonium is in the grey zone as its a metal who has associations with Preservation (and Ruin too) and we can't predict if it is auto burnable (I believe yes but it's a speculation for his effect)...Luckly it's not an issue as nobody could ingest Harmonium

@Brightlord Maelstrom A, B - Agree at 100% C - Indeed her Blade could be made by everyone.I only believe the Type 4's crafting process is beyond Viv's skill. I believe she could craft one if someone else explained the process to her but not be able to figure out it alone D - Nothing in the text seems to imply a Investiture draining and neither an Attive-Passive's switch for the Blade. This made me think that Azure's Blade is a superior Type-4 than Nightblood. An affordable and not suicide weapon designed after the Roshar's Shardblades E - Only that the possible timeframe is under the 300 years but this only because 341 years pass between HoA and AoL and both WB and TWOTK happen in the meanwhil

Ehm no...Every kind of Healing (except the Selish ones as they work under other principle)will be able to fix Rysn's damage. Regrowth didn't work because Rysn sees herself unable to walk as her normal state now. It's not something to fix for her because her Cognitive Self sees herself as unable to walk (it's exactly the same thing that prevent Kal from healing his Scars). Everything I said before will be still true if Surgebinding's Stormlight is involved EDIT: I wrote the post at the same time @Kasimir did and he is right and my reply unnecessary XD

That is because she has a bit of Divine Breath inside of her. What I was trying to explain you is that she is below any regular Returned in this regard and Nightblood's creation was well above the skill of beings with tons of Breath and quite genius in Awakening (Neither Vasher knows the details on Nightblood's Awakening). Without considerate the simple fact, that Awakening a Nightblood-like sword will need to the Awakener to have at least 20.000 Breath to have the right Heightening only to try the task. If someone explains her the process, I could see her uses it (also if again this will require at least 20k Breath) but she developing the Type4's process alone is extremelly unlikely

That is far above her natural intuite. Everyone with a lot of Breath will start to understand intuit Commands. But Nightblood is far above everything we saw so far. Also Returned can't easily figure out the method. Vasher also with his sperimentation and the past Breath's count....still don't complete understand Nightblood's existence

Roshar is often described as weird place. Where phenomens Cosmere wide manifest differently there. It's possible on Roshar you could access a glimpse of the Beyond (but I find it unlikely as Brandon doesn't want to give us an answer) or actually Dalinar heard a glimpse of past or yet A piece of Evi remained in the Spiritual (it's rare but could happen by WoB). If the last is the case, I believe this didn't happen naturally and someone setted this (maybe Cultivation)

Nightblood could be there bot not be the weapon used to kill her. If he was...it could be did without remove his cover so no 3 Aspects destroyed. By the way, I am not saying Nightblood wasn't used to kill her, simply we don't know

there were at least 12 Beads of Lerasium but many people believe there were 16 originally. 9 to make the Original Mistborn+ the one Elend used+ the one Hoid stolen+ kept by Rashek for himself (unknown use)

We don't know if Vasher killed her with Nightblood. And also in this case, it's still debate's argument by Cosmere's Arcanists if someone killed by Nightblood's full power is completelly to the point to not reach the Beyond

I may be wrong indeed. Anyway after thinking about Renarin's case for some days. I change my mind another more controversial. I could see Renarin's Powers as Voidbindnig (probably both of Surges are in their Voidish Forms) IF the Fused are not Voidbinder. I wanted to open a topic about but I have not the time to do it properly. In my optic the Fused are.... organic "Savant fabrial users" (honestly I don't know how to call them) and they are simply employing some organic version of the Surge Fabrial we already saw.

Indeed Baon and Galladon have nothing in common...really nothing (except the base stuff of be both humans and males)

They burn Pewter almost every moment of the day. Do you really need an explicit mention to Elend using Pewter in a crazy battle ? Anyway the simple fact he runned out of them is an implicit proof as they burn really slow and would last hours (a bit less for Elend because it's very powerful in allomancy)

Mmm I am not too sure to follow you. Connections change all' the time into someone's Life. Just because here someone could rawly add a connection, It's not too troublesome. Most of the magic does It also if It's not explicity descripted.

Why did you say Skai wasn't a great guy? We know nothing of him or Aona.
