Hemalurgy and spren

[Silva]

I might have gotten some of this wrong, but in Edgedancer it seems as though Lift can touch Wyndle. Theoretically, could she hemalurgically spike him and if so what would happen?

[Farnsworth]

Lift can touch Wyndle because she's been pushed a bit into the CR by the Nightwatcher. The spike, however, wouldn't be pushed into the CR, so I don't think it could spike a spren. Basically, stuff that Lift holds doesn't have the same ability that she does.

@SilvaThere is a WoB which states that one could spike attributes from a spren. This for instance:

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...

or this:

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.

Lift could spike Wyndle, but even if she wanted to and knew how, there is no way she would stay focused on it for long enough to get the materials and actually do it.

On the Contrary, Lift would get distracted at just the right time that at some point down the road, all of the materials would present themselves to her at the perfect time for her to complete the task.
