As long as he knows it, he can eat soulcasted meat. WoB:
 

Lift uses Lifelight not because she's an Edgedancer, but because this is her boon from Cultivation. Normal Edgedancers use Stormlight to power their Surges, they can't use Lifelight as far as we know. The only person that can use it and generate it is a Nightwatcher's Bondsmith and that position is open for now. It should be possible for a Skybreaker to also bond Nightwatcher and use Lifelight as their fuel, but that Lifelight would be generated more like how Navani and Dalinar generate their light, not how Lift does it by metabolizing food. But your character could have visited Nightwatcher and asked them for the ability to generate Lifelight just like Lift can and Nightwatcher granted them this boon and an appropriate curse.
However, in your case an Unoathed wouldn't be able to use any light, not even Stormlight, and won't be able to use Surges. They don't have a Radiant bond with their spren and it's this bond that allows them to draw Stormlight in and use it to power Surges. But with the boon from Nightwatcher they might be able to hold it and get some healing and enhancement effects like Stormlight gives, but with no Surges because they are Unoathed. 
RoW ch 60:
 
 

Allomancy is a gift that grants you strength to preserve yourself, that's why it's end-positive. The Shard of Preservation isn't about preserving itself, just like the Shard of Ruin isn't about destroying itself, they can fuel any kinds of interactions so the fact that Allomancy draws from Preservation, which might seem like it weakens it, doesn't matter to the Shard - and it doesn't weaken it, the power once drawn will return to the Shard after being used. 
As for Feruchemy being of Harmony, that's not the case. Invested Arts are born from interactions between the world and Shards present on it. Feruchemy is a merger of both Ruin and Preservation and it represents the balance between those two. I don't think we know why Feruchemy is end-neutra;, but if I were to guess I would say it's because Preservation's magic is end-positive and Ruin's one is end-negative, which sums up to end-neutral. An Invested Art born from mixing two Shards doesn't always end up end-neutral. For example all magics on Sel are end-positive, despite them all coming from both Devotion and Dominion. Surgebinding also is end-positive, despite being of both Cultivation and Honor. But again, we don't know why Feruchemy is end-neutral or even if there are any rules dictating how a mixed magic will be fueled.
 
 
 
 
 

Ars Arcanum of TLM did mention that the idea of Marsh as the impersonation of death is spreading throughout Cosmere, asking if this is something supernatural. I personally think this is a combination of those two factors - Worldhoppers do spread the news about Marsh, but due to Scadrian perception of Death as Marsh, other words might subconsciously also perceive death as looking like Marsh (due to the Spiritual Ideal of Death shifting to match that of Scadrians).

Hello, welcome to the Shard. Check out Sharder FAQ for some useful tips  
That's a very good question. Unfortunately the answer is no. Breaths and Shardplates are essentially made out of the same thing - Investiture. Investiture is a magical energy that can be manifested in many different ways and is even making up the souls of people. Breaths and Stormlight are gaseous Investiture, Shardblades and Shardplates are Investiture in the solid form (it's called a god metal), even spren are made out of pure investiture (that's why they turn into god metals, they are very highly invested). Because of that the system would already consider a Shardplate to be Awakened. That's why it would be impossible to Awaken it. 
The basic rule in Cosmere is that investiture resists investiture - the more something is invested, the more it will resist being invested by something else. People like Radiants or Awakeners are more invested than average people and some magics will have trouble affecting them (like Soulcasting for example). This is also the reason why a Shardplate or a Shardblade stops Shardblade cuts - because they are highly invested and that stops it. This means that something that is highly invested can resist or even stop a Shardblade cut - you can Awaken something with lots of Breaths and it would be able to stop a Shardblade. 
Here are some WoBs for you about this (Words of Brandon):
 
 
 
 

Roshar doesn't have a standard magnetic field fueled by the dynamo effect in its core - there is no tectonic activity on Roshar, there is most likely no active core on Roshar. Whole Roshar was artificially created this way by Adonalsium, Shinovar was later created to resemble Ashyn.
I don't think climate has much to do with magnetic poles, rather than with axial tilt (which is 0 on Roshar), latitude, ocean currents and mountain ranges. But Roshar has continent sized hurricanes coming every few days so we can throw all of this into a trash can - except ocean currents I guess. The colder water from the southern pole is carried by currents towards the southern tip of Roshar - Frostlands - and that's why it's "cold". Hotter waters from the equator are carried into the Reshi sea, making this area hot. Azir is a bit deserted because there are relatively few rivers there - less water for plants to grow - and being separated on three sides by massive mountains doesn't help. The highstorms are also much stronger on the eastern side of the continent, so vegetation on the western side can be more lush.
In the end I don't think we will find an answer to this question. It was just made this way and that's it. 
 
 
 
 

We will see. I don't think it was breaking his oath, but his Highspren might be disappointed. Perception will matter a lot here. If Szeth believed that by doing this he was protecting Dalinar, it most likely wouldn't matter. However it seems it wasn't done for this reason, Szeth did it out of anger. He disobeyed Dalinar, but I don't think it would mean breaking oaths. He just went a step backwards. Szeth hasn't sworn the 4th Ideal yet, so he still has to follow Dalinar. RoW ch 113:
However this might count as something positive, a step towards his 4th Ideal. He made his own choice, trusting his own judgement, something that the 4th Ideal requires of him. RoW I-7:
 
He did. Quote above plus:
Not even Szeth knows Odium was there. RoW ch 114:

Hello, welcome to the Shard. Check out Sharder FAQ for some useful hints.
 
This seems unlikely. Metallic Arts are generally hard to fuel by external sources. Lift metabolizes food into Lifelight directly, which is keyed to Cultivation. This most likely will prevent her from using it to fuel Allomancy, if she were to have it. WoBs seems to all agree that it would take some extra work for Rosharan light to fuel Allomancy - just having it is not enough. I believe it would work if you were to unkey the light, just like unkeyed Dor can fuel other Invested Arts - but Lift has no means of unkeying her Lifelight. WoBs:
 
 
 
 
 

Yes, this is possible. You can either tap so much heat that you will burn people with your touch, or store it to create frostbites on others. You're right that a Firesoul would be mostly immune to the effects of increasing or decreasing their temperature - Feruchemy protects them from that - but there are still some limits. It's possible to store/tap too much heat and hurt yourself in the process, but this is really hard to do, even if you're a  brass compounder. This protection seems to be more internal than external - if you want to walk through fire, you should store heat, not tap it. Becoming hotter won't be as helpful as storing heat that is transferred to you by fire (but we don't know if becoming as hot as fire would prevent you from being harmed, it seems reasonable to assume this would happen). 
One risk which is clear is tapping so much heat that you will melt your brassminds (~930 degrees C), or even much earlier when your clothes would self-ignite (for cotton it's between 200-400 degrees C). Both of those things might harm you, molten brass will for sure harm you and it will most likely prevent you from using your brassmind (while you theoretically can store attributes in molten metals, it will have some effect on investiture, so I imagine it will not end well even for a Firesoul).
However there are low limits in Feruchemy, there is only so much attribute you're allowed to store. We don't know what those limits are in the case of brassminds, but they should prevent you from storing too much heat which would harm you. You most definitely can't store all your heat at once and lower your temperature to the absolute 0K, that's for sure.
 
 
 
If you also have access to healing, you can extend the upper limits of brass Feruchemy and heal yourself from any self-inflicted damage. On the very hypothetical end of the spectrum, providing infinite investiture, a Fullborn can tap so much heat and mass that he will become a star - however in this hypothetical scenario infinite healing is a must, otherwise he would die waaaay earlier.
Still, this suggests that you might be able to tap heat even from molten brassmind and reach much higher temperatures, as long as you have enough healing (a huge amount of healing I must add). But unless you want to melt steel with your bare hands, there is no need for you to go anywhere near brass-melting temperatures. Burns can be caused by just 44 degrees C, 70 degrees C will be immediately destructive to tissue. Stick with those temperatures and save your dignity and clothes.
 

Screaming when? In both RoW and OB, Shallan never tried to summon Testament as a Shardblade and only then a deadeye screams. However, in WoK and WoR I believe that every Shardblade Shallan summoned was Testament, not Pattern, and it didn't scream too. Why? Shallan is already in the process of reswearing her broken Oaths with Testament, thus she is reconstructing her bond with her, which is a way to resurrect a deadeye (only if done by their original Radiant, the one who broke their bond). Moreover, screaming is a conscious decision made by a deadeye - Dalinar's Oathbringer was screaming less than others, because they remembered oaths Dalinar made, while every dead platespren is content in their state, thus none of them scream. Testament, because she willingly went to bond with Shallan most likely knowing she will die, might have accepted her fate and that may also be the reason she didn't scream at Shallan. I suspect however that the primary reason is that Shallan has started to reconstruct her Oaths, one of which probably was "I'm terrified" said to Testament in WoK before she Soulcasted a goblet into blood. Testament is not fully dead anymore. OB ch 89:

We don't know Hoid's end goal, that's a big RAFO. All we know is that Hoid wants to stop Odium by all means necessary (even sacrificing Roshar). There is something in his past that he deeply regrets doing and many think this is about the Shattering. Many people believe that Hoid wants to restore Adonalsium by recombining all Shards - that's why he's collecting all invested arts by this theory, to gain needed Connection to all Shards. There is even one WoB in which Brandon hinted that Hoid wants to "make that which once was." From his interactions with Sazed from SA letters and his involvement with Wax, it seems unlikely that Hoid is against Harmony, rather they seem to be allies right now as Sazed is one of few who sees Odium as a great threat to Cosmere.
 
 
 

Yes, every Nalthian will get a Breath when born, it doesn't matter that their parents are both drabs. 

Correction 80. 300 Radiants from 2 orders abandoned their Oaths at the Feverstone Keep. WoK ch 52:
2000 Honorspren were killed during Recreance. That's the entire species of spren gone. Other spren were probably similarly numbered, but only Honorspren answered to the call in the fullest. So there still should be high thousands of deadeye spren all around Roshar. RoW ch 87:
 
Yes, I've noticed that too and there are some WoBs on that, but they don't show the full picture. In my opinion two things have to  happen to leave behind a Shardblade:
You have to be at 3rd Oath to be able to summon the blade in the first place. Those of 1st and 2nd Ideal would not have left a Shardblade behind, just a deadeye spren in CR. You have to break your Oaths while having your spren in the form of a Shardblade. If you don't do that, the spren would be deadeyed in CR, they wouldn't have left behind a Shardblade. For example Syl wasn't left behind as a Shardblade when Kaladin almost broke his Oaths because he wasn't of 3rd Ideal, nor Testament was said to be left as a Shardblade in the garden because she wasn't summoned as a Shardblade at that time.
The Feverstone Keep was probably a unique event, one of a kind. The Recreance took place over a few days, most Radiants and their spren independently came to the same conclusion and abandoned their Oaths - they would most likely do it in silence, alone, without summoning their blades, thus leaving behind only a dead spren in CR. That's my explanation why there aren't thousands of Shardblades laying around, just a few hundreds. 
But that still is a lot of missing Shardblades . Maya is a Cultivationspren, even if only Windrunners and Stonewards left their Shardblades in such numbers, there clearly were others that did the same - probably for the sake of humanity in the future, leaving them weapons to fight against Odium, just in case. Where are they? 
Yes, I agree that many are hidden in Shinovar - they have a tendency to collect fancy swords. They also invaded Roshar on several occasions using cavalry, Honorblades and Surges. They might have even used those invasions to cover up that they were collecting Shardblades. They certainly have a small cache of Shardblades by now. Skybreakers also have a few of them. But many blades were lost to weather, crem, or the ocean. Around half of them. Not a satisfying answer but that's a canon for now.
 
 
 

They would not be benefited at all. They can't use Stormlight, Stormlight doesn't "fill" metals. Metals are a Scadrian thing, Stormlight is Rosharan. Unless a Feruchemist is also a Surgebinder and has a means of unkeying Stormlight - which is hard as nobody ever did that - they can't use Stormlight in combination with their Metallic arts. Lots of WoBs for you:
 
 
 
 
 
 

There is no confirmation yet (maybe in KoWT) but that's a popular theory that makes a lot of sense. 

Time still is in the Spiritual Realm, but not really in the same way as it is in the Physical Realm. In SR the time and space are compound into one - time and distance doesn't matter. But Shards still can't travel back in time, they are still moving forward in time, just like you do. However because of this weirdness, sometimes things can start happening as an echo of future Connections that will form, but aren't formed yet - that's why Syl knew Kaladin before they met, because this future Connection was echoing.
Changes still are happening in the Spiritual Realm over time - future sight is the proof of it. The fact that you see a split future the further away you look, or you're influenced by someone else seeing the future, tells you that the future isn't set in metal even in the Spiritual Realm (because that's where you look when seeing the future). Changes are happening, souls are developing, forming new Connections and stuff like that. Things aren't constant in SR, they move through time but just different.
 
 

Hello, welcome to the forum!
The way the Surge of Gravitation changes the gravitational acceleration and the direction of it isn't by changing masses or Affecting spacetime, it's by changing the spiritual Connection to gravity of affected objects. In Cosmere the Physical Realm is only one "dimension" of reality, there is also the Cognitive Realm (realm of the mind) and the Spiritual Realm where investiture and souls exist. The Surge of Gravitation affects your Connection to gravity, Connecting you to a virtual supermassive object in the Lashed direction, that doesn't actually exist. It doesn't change mass or warp spacetime, all work is done in the Spiritual Realm, not Physical. WoBs:
 
 
 
No, that's not how time dilation works. Planets with double the mass of Earth don't have half as slow time passage. The difference in time dilation caused on such a low mass scale is miniscule. For example the Sun is around one million times more massive than the Earth and on the surface of the Sun time passes slower only by a minute or so per year. That's nothing.
Because the Surge of Gravity doesn't affect masses or warp spacetime, no gravitational time dilation would happen - I guess, depending on how the Spiritual Connection would play with it. Would it fool the soul so much that it would behave like it was in the gravitational field dictated by a Lashing or not? If yes then gravitational time dilation would happen, but you would need massive amounts of Lashing - you probably can't even have that much Stormlight in the first place to generate such visible effects. The time dilation that would be important is due to speeds involved - a Surgebinder can Lash himself to eventually reach near light speed velocities and that would make him experience a considerable time dilation.
That's not something that is happening in books. The world around them doesn't suddenly slow down when they use the Surge of Gravitation. 
You really went wild by the end here. All of this doesn't work like that. Reverse Lashing doesn't work like that, it's a combination of the Surges of Gravitation and Adhesion. And backwards time travel is definitely and canonically impossible in Cosmere:
 

Hello, welcome to the Shard  What other books have you read? Have you read Mistborn Era 2, or The Secret History?
A Shard is made out of two major parts: a Shard, which is the power and a Vessel, who is a person holding that power. A Vessel is the mind of a Shard, they control the power. Sazed is now the Vessel (the mind) of both combined Shards of Ruin and Preservation, the Vessel of Harmony. For Preservation to give up his mind it means he used the essence of his own mind - the soul of the Vessel you might say - to trap Ruin's mind. This mind, this soul is made out of the same stuff that everything else is made out of, it's the same thing that Shardic power is made out of, the same stuff that powers Metallic Arts - investiture - which basically is energy. Preservation, or rather Leras - the Vessel of Preservation - used up his own soul, his mind, to trap Ruin's mind, or rather Ati - the Vessel of Ruin. 
Releasing Ruin from his prison didn't bring back Preservation's mind. Leras was gone, he was almost dead at this point and his mind was used up as power - there was no going back from that. When Vin Ascended, the former Vessel of Preservation, Leras, had finally died, leaving just empty Shardic power with no mind to control it (this happened just after Elend talked with the Mist Spirit, after taking over the new Koloss army on his own). Vin provided a new mind for Preservation, becoming the new Vessel of Preservation.
Some WoBs, Words of Brandon from Annotations to Mistborn:
 
HoA epigraphs ch 55:

What do you mean non-human? Animals? Not possible generally, they lack sufficient intelligence to use powers even if they got them somehow. Non-human intelligent species like Singers, Kandra or Sho-Del? Fully possible and we've already seen Kandra using Metallic Arts in SoS.
To use metalminds you either need to be a  Feruchemist (by birth or Hemalurgy), or have unsealed Malwish metalminds. It's just invested art, like any other.
Note: Below in my post I'm using the term "human level" meaning not just humans, but all kinds of sapient, humanoid species like Singers, Kandra or Sho-Del etc.
A normal animal would need to become really intelligent, comparable to human levels, to be able to use invested arts given to them - you can do that with Hemalurgy but that's a brutal way.
 
Chasmfiends or Ryshadium are still not intelligent enough to be on a human level. They have above animal intelligence, but they are still not sapient to do that.
Mistwraiths are mentally stunted people. They have a mental blockade. I would say for them it's also impossible.
Spren - True Spren should be able to do that. They are intelligent and sapient, and as seen by Syl in early chapters of WoK, they can use some simple Surges. Lesser spren aren't sapient, they aren’t intelligent enough. But they are a piece of raw investiture, using invested arts, especially genetic ones, might be different for them.
 
What you need for this to work is a human level intelligence. You can achieve that through different means. One is Hemalurgy, have your squirrel being spiked by a copper spike or two, giving it enough intelligence. Second is being a Kandra in a squirrel's body - they're either on some mission, or they've liked being a squirrel so much, that they've stayed like that for centuries and they've forgotten how to switch back or change their body to create a human-like vocal cords. Thirdly make it a squirrel that lives/lived on Roshar and had entered a symbiotic bond with some kind of spren that increased its intelligence to human-levels. Lastly, Tress spoilers:
Or ignore it and have fun, that's always an option.  

I don't think so. There is some cognitive aspect in a spike, everything has it, but it's probably not significantly developed. "Talking" to it won't change anything, the spike isn't sapient, sentient or fully self-aware. Soulcasting a spike into something else is pointless (it wouldn't change anything) and would require a looot of investiture, because investiture resists investiture, and spikes are invested. Forgery also wouldn't work. In both cases, Soulcasting and Forgery, you can only affect the metal and the charge it holds, and I don't think you can convince it to think it's in a body without adding anything else. It would be easier to take a piece of wood, nail a spike into it and then Soulcast/Forge it into a piece of meat - that's possible and much easier to do. But just sticking it in a piece of meat is even easier to do. 
It's probably more spiritual, I think a spike needs some spirit web to attach itself to it, which stops decay. The spirit web needs to be big enough to trick a spike into thinking that's something living, some animal, person etc. A piece of meat is ideal for it. 
 
 
But this isn't needed anymore. TLM Ars Arcanum states that Hemalurgic decay is a thing of the past - they've found an easier way to stop it or it's because of Harmony's nature which somehow stopped, like it stopped Hemalurgic compounding. The easiest solution might be to put a spike into an aluminum box for example. But I would guess it's something different, not some object, maybe a proper Command? Set's scientists handled spikes openly, with no box or no additional objects so I think this might be something different, Relmathic in nature (if this wasn't Harmony's doing, WoB seems to deny it, telling decay still happens in Cosmere, they just know how to avoid it). TLM Ars Arcanum:
 
 
 

You didn't say it must be safe to activate  
Anti-investiture bombs are the best. Just use three gemstones, one holding Stormlight, the second anti-Stormlight - use tuning forks to drag investiture from them both into the third, empty gemstone, placed in between the two. The Stormlight will interact with the anti-Stormlight and boom! However this will work on a small scale, not with large gemstones, because the explosion would happen with minimal amount of interaction between investiture and anti-investiture, blowing all gemstones to pieces before most of investiture got transferred to the central gemstone. This isn't that big of the problem with smaller gemstones, as RoW showed us. 
This anti-investiture bomb can be made with any kind of investiture - two jars of Dor, one filled with anti-Dor produced in the same way Navani produced anti-Light. Throw one at the other and boom. Capture some Mists, or use Metalminds, fill one with anti-investiture and transfer investiture from the other one into that with anti-investiture. Anti-Breaths - make those and with "my Breath to yours" Command, transferring your Breaths into the object containing anti-Breaths. Remember, investiture and anti-investiture must be under pressure to cause an explosion.
Use Aether spores - some mechanism to throw water into a barrel filled with Sunlight spores for example. That's a more conventional type of bomb.
Malwish use F-iron to somehow store the weight of their ariships - you can do the same with F-brass, but in reverse. Have a big metalmind filled with lots of heat and make it release all of that heat at once into the air. The expansion of extremely heated air will cause an explosion.
Yes. But leech only investiture not anti-Investiture. Anti-investiture would annihilate your soul. For bigger bombs you would need a lot of chromium.
Yeah, Zephyr and Sunlight spores would make a nice explosion together.
I don't think so. The explosion in gemstones with anti-Light happens because the investiture is under pressure, when it's outside, like a soul, there is no explosion. Breaking a gemstone would just release the investiture without having any effect. RoW ch 97:
 

Technically yes, but in practicality no:
Shardblade are already full of investiture, they can't fit additional Hemalurgic charge:
Also Shardblades are made of an alloy of Tanavastium and Koravellium, god metals of both Honor and Cultivation. Pure Tanavastium is in Honorblades, but the problem is the same - you need to separate a piece of it from the blade to make it work like a spike.
 

There is only one person that we know of, who has a spike in one of his eyes. That's Kelsier for sure. And WoB confirmed it:
 
 
Edit: @Bondsmith-Edgedancer about theories, Kelsier as CS reattached himself via a spike to the mistwraith's body, who consumed his bones and recreated Kelsier's body - that body isn't his, it's a mistwraith with his bones. That's a theory at least, WoBs support it:
 
 
 

Nohadon was a Dawnshard - that's very likely (Here is the topic about it if you want to read). Then I think he hid his Dawnshard in the vision that Dalinar entered at the end of WoR. But Dalinar hasn't become a Dawnshard yet. Nor was he one during the OB battle. That wasn't Dawnshard (because Odium's words "we killed you" wouldn't make any sense). He either partially Ascended to Honor (which is the most prominent theory) or did something else, maybe related to Adonalsium himself. The power that Bondsmiths used to have is likely Perpendicularity, not just Dawnshards (Ishar created Perpendicularity without any Dawnshard).
When somebody Ascend, it's about Shards, not Dawnshards. You don't Ascend to a Dawnshard, you become one. If Dalinar was a Dawnshard the change would be very visible. He would exhibit Heightening-like attributes. Not to mention holding a Dawnshard would warp his soul in such a dangerous way that it would likely hurt Stormfather or change him. Rysn was forbidden to bond a spren, not just because she would access Surgebinding.
 
 
No. Brandon RAFO if Rysn would have the same Torment as Hoid. But we know different Dawnshards have different effects, and one is very different from the others, so it's likely that Torments are also different.
 
 

Riina knows Hoid can't kill or hurt somebody because of his Dawnshard. This still works on him. But he can do something to her, which would be very nasty and unpleasant, might even cause her death, nut technically wouldn't count as hurting her. This is what she feared. WoB:
