Pitched battles are shockingly stupid. The Europeans, a people whose continent is largely fields and flat land, tried to get battles in forest, marsh, and hills because fighting pitched battles on neutral ground is so shockingly dumb. I don't mean to be rude, even if it doesn't seem like it, I'm trying to point out that a pitched battle is unlikely for both sides, especially when you have world's worth of people on both sides.
But moving metalborn is far easier.
Still, I think your estimates about the size of Radiants is a little too hopeful. Radiants depend on the psychology of spren, some who think Odium is preferable to humans. Meanwhile, metalborn are just products of population trends.
Uhh-the reason why their fully charged is so that the wearer can see through all three realms, and push on virtually anything.
What are you mentioning here? Sorry, I couldn't find it.
Generators? But yeah, this one's tough to imagine. It'd likely involve multiple, massive fleets of airships primed with hundreds of metalborn.
Kandra? But yeah, they can't communicate...maybe a new use of duraluminum? But Bronze detects all investiture. Or at least the high amount being expelled by transcending the border between realms.
Other theory: bloodmakers used as meat bags in the unlikely case of a large-scale battle.
Here's the thing about all of these theories, though. Modern warfare (even some older warfare) isn't necessarily about large-scale battles. Or rather, those who are remembered as military geniuses don't start those. Instead, it's logistics, careful planning, large-scale ambushes, and multiple small-scale ambushes. It's getting behind enemy lines and causing disruptances. It's putting psychological fear in your enemy. Roshar has the advantage when everyone around fights the same and has shared history. But Brandon has said that Kelsier would win in a fight between him and Kaladin, and the reason why reflects their planets' warfare. Roshar will try very, very hard to catch Scadrian forces. But said forces will do their best do avoid, draw in, ambush, and launch surprise offensives. And Scadrial is well equipped to do that, while Roshar is well equipped to carry out their strategy. No doubt, in a siege or pitched battle, Roshar will win. But I think, based on existing martial traditions and magic, Scadrial will win in virtually anything else. They will not win on a massive offensive campaign. They will win if they can draw Rosharan forces, trap them briefly in an ambush, and then launch a surprise attack on immobile Rosharan war commands and cities. Roshar can try to siege Scadrian cities, but things like land mines and artillery will make that hard. Bronze compounders and allomancers can keep watch alongside tin metalborn to make sure enemies don't slip past, while iron and pewter users can catch those that do. Twinborn backed up by allomancers and ferrings is just such an appealing model for war. However, Scadrial will not win in the conventional sense. If they try to, Roshar will grab them by the neck and break them. Instead, they'll wear the people and troops of Roshar down. They'll drive Roshar's command insane with surprise attacks and deft reactions. Scadrians literally can use Bronze compounders to quickly analyze situations to come up with the best outcomes, Electrum allomancy and feruchemacy is immensly useful on the battlefield, and the destructive capabilities of even a coinshot are incredible. (Wax's rampage in Bilming). Sure, Radiants are probably more versatile than I give them credit for. But their entire model (besides Lightweavers) is to provide a bulwark between their immortal, untiring, overwhelming enemy and humanity. That's not a group designed for subtlety or deft militaristic maneuvering. Most of Scadrial is. What isn't, it's designed to be even more domineering than Roshar. Massive (or at least fairly large) airships. (Thanks Frustration!) A navy that can far outpace everything Roshar has. It would be close, definitely, but in the end, Scadrial is just more annoying.
Sorry, I meant storing Identity.
And it took Wax some ten minutes.
I think it'd take a talented Bondsmith. Of which we have none.
Yeah, you're right, I should've considered that. But the idea of a metal ship is inconceivable to the Rosharans, while it's a tiny aside to Scadrial.
Alright, thanks.
Hey, could Chromium drain Stormlight? Because if it can, that's also huge. Think about it. Flying platforms crashed if they can get one person onboard. Radiants taken out mid-battle. It'd be a pretty large (if hard to exploit) advantage.
