Can you reforged a metalmind?

[Sythrin]

We know that only natural born twinborns or a Fullborn could compound.

With Hemalurgy you have identity contamination unless you somehow manages to remove the identity from a spike or the spiked (but that is another toppic)

But what happens to metalminds that are reforged?

For example what would happen if Wax took one of his ironminds, made them to steel and than burned it? I believe Sanderson has mentioned that the investiture does not get lost or at least all of it, but gets inaxcecable. But what if you can burn the same metal? Identity contamination should not be an issue right?

Nope - at least not reforge into an alloy - you could melt down a coppermind to change the shape - and the memories would still be accessible as long as it is still Copper at then end, but if you changed an Ironmind into Steel - the power could be sensed, but not accessed, just like Vin trying to burn Sazed's TinMind.

It seems that taking something metal that is Invested and melting it down, and reforging it, does not destroy the Investiture in it. For example the spike that got turned into a bullet.

Brandon Sanderson

Well, and the-- yeah. There are other examples as well.

Mason Wheeler

If that doesn't ruin its Invested nature, what would happen if Wax were to take one of his ironminds, have that melted and alloyed into steel, and then tried to burn it?

Brandon Sanderson

So you are saying mixing in-- right. Um, this would probably not work. But I'd have to go to the document on this one, because I've theorized in it. So I'm going to say probably won't work, but I have to go to my document, so Notes And Find Out. As soon as we get into the really detailed-- One of the things I want, even when I was building the Mistborn magics, is I wanted it to get really complicated. Because, my philosophy was making a wheel is easy to understand what's going on. Making a car uses all the same physics and simple tools, but is infinitely--well, you know, not infinitely--hugely more complex. Making a spaceship goes beyond that. And I wanted when we dug into all the actual mechanics it all works, but it's like the difference between making an abacus and making a computer. And we're starting to stray-- not into computer-making realms, but starting to stray into combustion-making realms, and so these are the sort of things that I just can't talk about off the cuff as easily. Because I have this document and I'm like "this, this, this, this." Does that makes sense?

So I'm going to say that probably wouldn't work. I believe what is going to happen there is you're probably going to end up with one of these things where you see a reservoir there but you can't access it that happens quite a bit when things get muddled once you mix in other metals and things like that. But I can't give you 100% on that without the notes to double check myself.

What would happen if a Feruchemist fills, for example, a tin metalmind then mixes it to make a pewter metalmind? Does the stored attribute change? Is the Investiture gone when you melt the metal? What if he just makes it into a tin metalmind again?

Brandon Sanderson

If you make it impure, you'll keep the investiture, but won't be able to get it out. If you make it back into the same thing, you'll be fine, and can access it normally. If you try to fill it, after changing the composition to make another viable metal, it will act a little like a computer hard drive with corrupted sectors. Some of it will work for the new investiture, but you won't be able to fill it nearly as full. (Depending on how full it was before you melted down.)

This holds for basic uses of the metallurgic arts. Once you start playing with some of the more advanced parts of the magic, you can achieve different results, which are currently RAFO.

Similarly, if you were to soulcast a metal would it have similar effects of corrupting the investiture and making it inaccessible? Like if you turned a steel metalmind into pewter.

Brandon Sanderson

I've stayed away from soulcasting and forging in these types of discussions, as I feel my answers will dig too deeply and prompt more questions that, eventually, will lead to lots of RAFO type questions. I don't really want to go there--but I will say this. Changing invested objects with other magics is hard, and often requires such a force of investiture yourself, that it becomes very power-inefficient. Just like we can technically turn lead into gold right now--by spending way more money than the gold is worth.

BipedSnowman

So you could, for example, use electrolysis to dissolve a metalmind in water, then reverse the reaction later to get the investiture?

OR, better question, if you store investiture in one allotrope of iron, can your retrieve it off you change to a different allotrope?

Brandon Sanderson

I see no reason why these wouldn't work.

What happens when you break a Hemalurgic spike or metalmind? What happens to that power?

Brandon Sanderson

Hemalurgic power can be split among multiple spikes and reforged, but remember that the longer a spike is outside of a person, the more the power is going to decay. Things like splitting it will decay it even further. Metalminds can also be broken and still be accessed
