World Domination

[Through the Living Shadow he/him]

We've had a lot of hypotheticals about combat between magic systems, but how could they work together?

A radiant (choose the order) a Mistborn and a Feruchemist are sent to an alternate dimension (The Earth!).

They have a goal implanted within them-they must take over this planet within the shortest time possible, without this resulting in any of their deaths.

Each of them are the best of the best at what they do.

(It would be like Kaladin w/ Kelsier w/ Sazed all focused on world domination)

The radiants spren can manifest in this world like they would manifest in the Physical Realm

Radiant gets stormlight once a week, but this is a few pouches worth.

Mistborn/Feruchemist don’t have access to G-Metals, but can take whatever initial supplies they want/can carry

Main issue I see right off the bat is ensuring continuous resources for them

Oh yeah, that too.

First step, then, would be to take over some sort of metal refinery using emotional allomancy, get some source of clean A-Iron (This would probably be the easiest, most effective metal for them)

Oh and assume the Earth does not have cosmere books.

Alright, here's what ya gotta do.

Soulcaster soulcasts a blank set of Hemalurgic spikes. As of TLM you can spike someone without killing them, so you use Hemalurgy (plus functionally infinite metals from the soulcaster) to make either the Mistborn or the Feruchemist able to compound F-Nicrosil (for infinite Connection to easily conquer nations) and F-Duralumin (For enough Investiture to supply the Soulcaster).

Proceed to create a Hemalurgified Lord Ruler and conquer the world.

Hmmmm

promising, but there's a limit to how many spikes can go into one person, I think it capped in the teens.

Can you continue to invest already invested spikes?

Soulcaster could potentially be very dangerous.

A good source of Nicrosil could be nice, yes.

Does the Radiant know the required balances of metals? Oh that leads me to an interesting question. I'll ask it in Q&A

[First of the Tide He/him]

Okay, terrible idea that might not work and is only kinda world domination, kinda annihilation.

Mistborn flies an Elsecaller and the feruchemist up to upper atmosphere above.

Elsecaller spren turns into a giant disc(if a fork works, why can't this)->can supposedly  "protect against heat that could burn a person alive in seconds."

surely enough to cool a city-wide space enough to kill inhabitants.

If investiture is an issue, soul casting for hemalurgic spikes for unsealed metalminds

teleport to other cities and repeat

I think a Stoneward would be a pretty powerful force to have, cause they can literally just go through the ground where it's significantly harder to hit them, and they can disrupt any fortifications

Stoneward+Steelpushing combo?

that’s quite interesting

Then the feruchemist goes in while soldiers are distracted

[Aliroz-The-Confused]

Mistborn negotiates world peace with emotional allomancy and convinces all significant political leaders to arm-wrestle/pumpkin-throwing-contest/sock-organizing-contest Feruchemist for their positions.  Feruchemist cheats and wins.  Since these guys made world peace happen, and since the last respectable politician died on December 5, 2013, nobody rebels because everybody likes world peace and wants to see what happens next.

Radiant brings snacks for Mistborn and Feruchemist.  Radiant sees a piano.  Radiant learns how it works, then learns to play, and, by a twist of fate, turns out to be the greatest pianist since Liszt.  All other music is abandoned because nothing else has any appeal once the pinnacle has been heard.  This means the end of musical theater.

Upon being freed from the evil that is musical theater, humanity, in infinite gratitude, unanimously agrees to cede the planet to these newcomers.  All is well.

[Through The Living Grub He/Him]

Mistborn can kidnap/spike people in the night and make a koloss, which can create an army (would require a Soulcaster for the metal, or a solid supply of iron at the start). Countries are conquered or sign a treaty and come under the trio's control. This is even better because of the Earth's ~8 billion people, so there is still a sizeable workforce. An Elsecaller would make surprise troop deployments much more devastating. Feruchemist could store spike locations and their effects in a coppermind, and emotional allomancy makes conquering later countries much easier.

[Through The Living Ash he/him]

Lightweaver + Feruchemist to figure out how to fly an airplane = portable space laser.

Where do they spawn? Assuming they have no knowledge of our world and they end up in many countries, they're likely to get detained. If they try to escape, then they're likely to end up shot, or at the very least, unconscious until country's head of state decides what to do. Without info, they're likely to use their powers in public (probably enough in most countries). This risk would be mitigated if in an area without heavy control by a state, but that has other risks with crime/terrorism where the Feruchemist is the only one who can speak any language from our planet and none of them know anything about the political geography.

Edit: Even if they manage to get control over an area, it would be hard for them to expand or even rule.

Hhmm

Assume that they know their powers are an abnormality
