Questioner
So I have heard that it is harder to Push a Shardblade with Allomancy than it is a normal sword.
Brandon Sanderson
Yes.
Questioner
Is that true of both living and dead Shardblades?
Brandon Sanderson
Yes.
Questioner
Equally?
Brandon Sanderson
Uh, no.
Questioner
Okay, so it's even more difficult to Push one alive.
Brandon Sanderson
The thing-- An Invested object is more difficult with any of the magics. So, for instance, even a Feruchemical metalmind is going to be harder. Depends on how much it is Invested, and things like that. But, y'know, it can range from you barely notice it or don't even notice it to "Wow, that's hard to Push on". Same for a Hemalurgical spike, depending on how much Investiture is left over, how long has it been outside of a body, and things like that. Same thing Pushing on something inside a person's body, their Investiture is going to interfere with it.
Same thing, when you read White Sand, why a person slapping their hand through someone's stream of sand can throw off the entire creation of the sand mastery. It's just-- There's interference patterns, and things like that.
Questioner
And is that true of a Drab as well? Does the body affect--
Brandon Sanderson
The Drab is going to have less.
Questioner
So they just have less Investiture, but they still have some natural Investiture?
Brandon Sanderson
They do still have some. They've lost their Breath but that isn't the entirety of the Investiture inside of them.
Almost all of the times we see Vin--in fact I think every time--we see Vin, or someone in the Mistborn books, Pushing or Pulling on an Invested metal they are either drawing on the mist or they're Elend or the Lord Ruler who have the enhanced power, or something like that. Or it's a duralumin Push, or its one of the Inquisitors who's had a spike-- y'know, and things like that, that've-- And so it's not something that you see done very often in the Mistborn books.
Rubix
I can actually confirm that's correct.
Brandon Sanderson
Oh you guys looked it up?
Rubix
I checked.
Brandon Sanderson
I mean it can be done. And depending on Investiture it can be not even that hard to do but--
