Invocation

Here's the ones on BSandy's shop: https://store.brandonsanderson.com/vial-necklace/ & https://store.brandonsanderson.com/vials-of-metals/ There's no liquid in them, but they are official, technically. If you really want liquid, try olive oil. That should work.

Hemalurgy and...

In my defense, I am not an intelligent person. Hm...how about the prison from the Skybreaker test thing? The one that all the dudes were kept in the dark in.

Kredik Shaw, maybe. Many Inquisitors, the birth of Kelsier's scheme, guarded, and the Hoid/Kelsier punch meme, or maybe the Pits of Hathsin. Unless I missed something about it being Roshar-specific.

I have to agree with @Lunamor on this. Steel is cool, but even if you move fast you're still burning all of those calories that you then have to replenish just to be Sonic for a second. Gold makes you heal fast (so you can potentially donate organs and grow them back immediately) and just in general much better than the other metals. Steel is a close second, though.

There have been some theories about that, but I don't see it as much of a thing to happen. For one thing, I don't think any of them would put Taln or Ash back into it and they're both sitting in the back half of the books. They're proven weakpoints, Ash more so than Taln, but neither are good candidates to get tossed back into the very same thing that's left them broken to extremes. Dalinar is another oddity. He's Ascended once, sort of, and is also significantly older (in a physical sense, so Taln and Ash are debatable) than most of the other candidates, which doesn't spell out anything good for his ability to resist things like that without access to Stormlight and (RoW spoilers) Dalinar is also a monarch, along with Jasnah, so both make minimal sense for that reason too. Kaladin is the most likely for this to be the case, with his whole "self-sacrifice" thing. Shallan might be able to wall off the pain in another personality, but she's also not reliable in general. Szeth just isn't stable. I'm not entirely sure he qualifies as sane. Renarin...is an oddity in general. Personally, I think his futuresight will have its day of fame and it may not be the best idea to toss him into an incarnation of hell when you can use him as a radar for if the ones you do banish some people to that and they begin to slip. My money is more on them finding something else to solve their Odium problem, potentially a large perfect gem (maybe the core of Roshar or something) that they can trap the Shard in, while forcing Rayse himself to de-Ascend.

Least understood, but also even cooler for the oddities.

Welcome to the Shard! Truthwatcher gang

I had a whole theory posted somewhere else (I can't remember what I did with it) that Shallan managed to come into contact with whatever Unmade was there and it caused the initial split of personality and some bit of Connection lurks inside her, having corrupted her initial personality into what is now Formless.

I believe Kaladin made a shield once. But a suit of armor made of Blades wouldn't provide the same boosting of strength and endurance that Plate does.

Imagine Windrunners making a large apple-cutter looking thing out of Plate with the cutters on the bottom made from the Blade and then Lashing it downward a bunch of times in Roshar's first kinetic bombardment.

"Leshwi’s spear was lined with a silvery metal that resisted Shardblade cuts." Is that...not confirmation?

[Insert Law & Order clanging sound + jingles]

Imagine the sound of hundreds of 4th Oath Radiants jinglejangling across a stone battlefield.

Yes! That! It'd be clickyclacky but it'd probably work.

It would probably work based on sole Intent. A really thin layer of lesser spren would probably work.

Shardcape. Just integrate it.

I want in.

Gotta go with Hero of Ages for me. Even that one part in Oathbringer didn't hit me as hard as the end of that one did.

They may have been moving planets while Taldain's lockdown was happening, where their travel got restricted by Autonomy.

Red was venting right in front of me he's sus!

Ah. Interesting. Thank you.

Wait I thought there was a WOB about that not being possible without Hemalurgy. Did I miss something?

Hey, whatever works man. Gotta remember it somehow.
