Spiking a Radiant

[The Grumpy Elantrian]

How exactly does one steal the investiture of a radiant using hemalurgy?

I would assume an atium spike is needed since atium is supposed to be able to steal any attribute, but when you steal their investiture do you force the spren to bond to you via the spike or do you simply take their ability to use stormlight without the spren?

[Calderis]

It shouldn't require atium, but we don't know the breakdown of classifications in other systems. 

As far as their abilities, you can steel the bond... But that's a good way to end up with a dead spren.

Questioner

So, the fan page wanted to know. Would it be possible for Hemalurgy to steal a living Shardblade? That was the top voted question.

Brandon Sanderson

Ok, so you're bonded to a Shardblade. You get spiked, then they spike off the bond so that the Shardblade is bonded to someone else.

Questioner

I assume so...

Brandon Sanderson

But can they do it with a living Shardblade? You can definitely do it with a dead Shardblade because its just stealing the Connection. With a living Shardblade, yes you could do that 'though the spren could break the bind at will.

Questioner

So the spren would survive? That was the second-- the corollary--

Brandon Sanderson

Ehhh. Would the spren survive? The spren would survive as long as the oaths were--

Questioner

Intact?

Brandon Sanderson

--the person didn't break the oaths. But you could theoretically steal the bond, break the oaths, and kill the spren. If you wanted to. Its a very convoluted to kill a spren, they are easier to kill than that, but yes. You could do that. That is a viable but twisted route that you can do. You would end up with a dead spren and a Shardblade, so there is that. But there are easier ways to accomplish that...

As to just stealing the powers... You could do that if you spiked the Spren too.

Mr. Suit

Can spren - like Syl - be pierced by hemalurgic spike? Will it give some effect?

Brandon Sanderson

Yes. A spren can be pierced by Invested metal…

Oversleep

Could it be spiked?

Brandon Sanderson

Could a spike be used to give abilities to spren? That’s not going to work really well.

Oversleep

Could you steal from a spren?

Brandon Sanderson

Yes, you could steal the Investiture of a spren. Any Investiture can be used in a spike if you know what you’re doing. It’s actually not that hard to use one on a spren.

Oversleep

Because I thought you said Hemalurgy needs moving blood.

Brandon Sanderson

It needs, uh, yeah… there are places where spren have more physical form, more tangible form.

Questioner

Roshar?

Brandon Sanderson

No, no, no, not Roshar.

Questioner

The Cognitive Realm on Roshar?

Brandon Sanderson

Yeah, if you go to the Cognitive Realm on Roshar the spren act differently than they do.

Oversleep

So you could spike in the Cognitive Realm?

Brandon Sanderson

Yeah I’ll leave a RAFO with you on that. That’s your fifth one. So there are ways to get any Investiture into Hemalurgy if you know what you’re doing. But yeah this is not something that would be a common use for Hemalurgy. Let’s just say that.

Oversleep

We do not concern ourselves with common uses.

Brandon Sanderson

Yes, I know you don’t. But yeah Hemalurgy, when you’re spiking into somebody you… you’ll see when we get around to it.

Questioner (paraphrased)

If I wanted to Hemalurgically acquire a power from First of the Sun, which metal would the spike need to be?

Brandon Sanderson (paraphrased)

This is going to be pretty complicated, but several metals would work.

Questioner (paraphrased)

Would it involve Connection between the person being spiked and the bird?

Brandon Sanderson (paraphrased)

Well it would be even harder than on Roshar, where you need to somehow spike the spren and also the Radiant. You would need to spike the bird and steal the power, but also spike the person and steal Connection.
