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.

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.

When Khriss visits Scadrial, does Harmony know it?
Brandon Sanderson
(paraphrased)
*written* Some times He does. (more often than not, these days...) But it is possible to hide.
*spoken* Khriss doesn't have a lot of reasons to hide. She doesn't mind the attention, usually.

Is the programming-esque nature of the Dor a product of the power being in the Cognitive Realm or is it for some other reason?
Brandon Sanderson
(paraphrased)
A mixture of the Vessels' personalities, the fact that the power's in the Cognitive Realm, and the nature of Sel's focus.

Imagine a hypothetical Shard of Tenacity. What happens when the Vessel of that Shard dies?
Brandon Sanderson
(paraphrased)
The magic will change drastically. Among other things, it would be very easy for practitioners of that magic to become Cognitive Shadows.

Does Harmony have Straff Venture's hidden atium?
Brandon Sanderson
Harmony has everything he needs, but that doesn't answer your question. No, Harmony does not have Straff's atium.

If you made a sword-shaped nicrosil metalmind, and dumped a lot of unkeyed Investiture into it, could you make a Nightblood-esque Shardblade? And if you actually didn't go to the trouble and just dumped a lot of keyed Investiture into it, would that change the outcome?

You're getting close to how this type of thing works but you're missing a few things. Keep working on it.
