A Windspren

A lot of these suggestions have been really Amaram-y. Considering the way he turned out, I really hope that they aren't the Fourth Ideal.

I will accept that I cannot protect them all.

Skyward sounds kind of like the floating upside-down cities I've seen mentioned in connection to Ashyn. Let's hope for a Greater Roshar system novel!

Is it just me, or is the link broken?

Koloss do an all-out charge. Alethi set spears similarly to how they do against heavy cavalry. Koloss impale themselves against 12 ft-long spears and die. Alethi military superiority wins. Simple, and involves spears. I like it.

It could have to do with the fact that the Eyes are the body focus of Lucentia (crystal), and the Focus for Roshar is gemstones (from what we've seen).

Maybe Stick served as a Kandra's Blessing for some time? IDK, it might be waaay too Invested for even Adonalsium to handle, let alone a Kandra.

So, it seems that most people think Larkin are some sort of "Investiture Vacuums" that just consume any Investiture around them. However, I think that this isn't the case. When Rsyn gets her Larkin, there isn't really anything different about it (other than the silver eyes and wings), but when Nale uses the Larkin on Lift, it is described as sickly and weak looking. Therefore, I must conclude that Larkin just have the ability to use Stormlight, like a Surgebinder. The Larkin drew in the Stormlight to heal itself from injuries that Nale likely gave it. Naturally, to draw in Stormlight, the Larkin must have a bond with a spren. However, this is probably a higher spren, such as something below Radiantspren but above normal spren. The most likely candidates that we know of are Riverspren and Windspren, though there may be others. I hope I cleared some things up.

I also think that anything that is cognitively considered a gemstone can store Stormlight, not just the Polestones.

Well, lightsabers are supposed to have some Force-crystal thing (don't ask me, ask my friend. He's the Star Wars nerd, and I'm the Cosmere nerd) to direct the energy that makes up the blade of the lightsaber, so I think it's fair to assume that there's some Investiture affecting the lightsaber. Cap's shield, however, is just really overpowered metal.

Magic System: Surgebinding, because the sheer awesomeness of what you can do with it is mindblowing. If I could have any power, it would be the Surges of Gravitation and Regrowth. Character: Sylphrena, but since she's not there, Kaladin. Series: Hmm, tough one... How about... The Stormlight Archive, because I want book 3 NAAAAAOOOOOOWWW!!! (Yes, I'm 160% Stormlight fan)

The Powder Toy. It's a game.

How could there only be 2 ways of doing something? That scenario is pretty much impossible.

It would be more honrable to find another way.

I think this would be much easier to play on TPT. I'm also planning a full Cosmere-Wide that will include all of the magic systems.

Gravitation Surge + Progression Surge Falling with style, pulling objects towards you with Reverse Lashings, and being the worlds best doctor. You would also get unlimited healing from both passive Stormlight abilities, along with Pewter-level strength (and probably more than that), and Progression would allow you to grow food whenever you wanted to, as well as winning every gardening competition with 16 ton pumpkins or something Other choices Transportation Surge + Copper Feruchemy Travel all around the universe and store all of your information in a coppermind Gravitation Surge + Iron Feruchemy Advanced flight skills (I suppose you could basically replicate iron Feruchemy with just the Gravitation Surge, though changing gravity and changing mass are different) Transformation Surge + Awakening Soulcast grass figurines into titanium, and Awaken them for your own personal army.

He was more just cutting him to torture him, not really to take him apart.

When he was in that barn, he was cutting some kid open and poking at his insides. Not sure if that counts as dissection, but still...

Wouldn't Roshar be much, much more populated than Scadrial? Humans can only survive near the poles on Scadrial, and they have to survive in high temperatures and ashy conditions while Rosharans have an entire lush world with Stormlight enhancing their immune systems to the point where a few cases of the common cold are seen as a plague. It seems to me that Roshar could easily raise an army 3-4 times larger than the Scadrian one.

What if Kelsier got ahold of them, melted them into a spike, and used it to spike his Coginitive Shadown into a body? That could explain how he got Feruchemy.

There's also Atium compounding.

Perhaps it is a radioactive isotope of cesium, which is an alkali metal which has certain isotopes with glowing properties.

I think you're all forgetting that: a. Kanda can't kill people, so using them to replace leaders/generals is impossible if you can't kill them in the middle of a warcamp, get the body to a secure location for a few hours for the Kandra to eat and recreate it, and get them back into the warcamp before they have to attend any meetings or battles. b. Soothers/Rioters can only affect a few dozen people at once, so using them against an entire army is useless c. Koloss aren't nearly as powerful after their blood frenzy, and charging them before they get angry can easily beat them, as they have no coordination. d. A significant fraction of Allomancers were nobility, who wouldn't fight, and skaa, who couldn't reveal that they were Mistings.

Well, Wax stopped tapping the memory when he saw Kel's arms, so I would assume that there's still a good portion of memory left in the coin.

He could just had them the Coppermind coin, of course.
