If I remember right you can't because the Forgery can't give you the access to Preservation's power... But if you are already an allomancer (for example a Rioter) you may be problably Forgable in a Coinshot (and any other Misting) or a Mistborn. Somewhere in the Forum there are similar question to Mister Sanderson, I hope someone may post here, at the moment I can't

I imagine yes, unless with 11-30 Spikes also a very weak Misting may take control of an Inquisitor...More Spike=more easy to control.... Rashek can't allow that some Ska Rioter take control of an Inquisitor, and we never saw something like that...therefore they have some kind of "protection" to resist better to mind control

Someone who used a lot of Spikes, for an Human 4 or more Spike give to a Shard enough control over you, but less are safe. As far as we know a powerful allomancer may take control of you if you have enough Spike but you may protect yourself through A-Copper (both form Hemalurgy or Medallion) or Allumin Hat. Without thinkng about how difficoult would be in the AoL era to find someone with enough strenght to control you...They need a team of Allomancer to overcome your resistence.

Wait wait, you need to WANT (put the intent) performe Hemalurgy to create a Spike, then after if the Spike is put in the right place (also without any Intent) gift its power. The Shardholder of Ruin (or now Harmony) may puts the Intent instead to create a Spike, it's what we saw in the Mistborn trilogy with many of the Spike of Agent of Ruin... But without a Shard Interference, the Hemalurgist have to put the Intent to steal a specific trait, without you have just a murder. PS: Quite all the Magic Systems have need of some Intent to do what they do, Hemalurgy is not different

In Warbreaker Annotation (it's there if I remeber right) it's said that Nightblood make a bond with anyone who unleashed it and survive. From that moment this person will have no nausea or lust to held Nightblood.

The Ars Arcanum said Enhancement Allomancy, but I think the Author made a mistake at that time and it's wrong about what the allumin may steal

Hemalurgy is a Spiritual Genetic Enginering. It removes and implants part of Spiritual DNA with conseguence for the user. Of course this may be done with "average Spiritual DNA" (attributes that every human has) or "uncommon Spiritual DNA" (attributes and ability less common, like be a magic user)

Until we saw how difficoult is to create a Medallion we can't say anything about. If they need the tools that Kel lefted to them to make Medallions, this kind of device will be pretty limitated, without talking about the mix of power where the medallion's technology is pretty behind. The Hemalurgy has its own use and flexibility that the medalion probably can't reach, of course the Hemalurgy is less "cheap"

I define myself as an Atheist. But to be honest the stricty semantic of Atheist don't apply to my though..therefore I suppose to be in the between from Atheist and Agnostic (but very near to the atheist). I have need of many words to describe better my PoV and as all the Forum knows I began to make error in English when I try to explain long concept...therefore I will avoid you any kind of suffering

I am not sure about that. Ok that positive-End/negative-end are in-world knowledge therefore may be unclear. But we even know if the "Sacrifice" is build into Dahkor or it's simply a side effect, like to say "they may tap how much Dor they like but, they can't manage safety any kind of amount of Dor". The loss of life isn't probably something build into the magic system, it's like if the AonDor is Negative-End because the user may die using too much Dor, or if the Allomancy is negative-end because the Savantism at the end may kill you.

At the moment I start to think that in the Cognitive Realm you don't age...therefore when a worldhopper travel there, that amount of time don't age him. If the 17th Shard has some "homebase" in the cognitive, it possible that many agents remain live through the ages.

There is a WoB somewhere in the forum about Breaths as unstealble through Hemalurgy (if I remember right because the Breath is mainly physical while Hemalurgy works with the others realms) but a Divene Breath may be steal

The only thing that come to my mind from the informations about Inquisitor, is some kind of compatibility problem. Feruchemy is "build" around an Human User, you may give the power to another kind of creature with Hemalurgy..But the matching "Human Attribute-non-Human Attribute" works with some limitation (or power loss in the conversion). From my previous post I removed the Decay from the causes, because I thinked about it, also if a Spike loses some kind of efficienty with the Decay, many pratical limit (storing without die) of the Feruchemy are very below the possibility of the magic system (storing without thinking about your safeness). Example: I kill a Bloodmaker (I am an horrible person, I know) to make a F-Gold Spike, then because I am an idiot and I have fear of the needle, I wait a long time before gifting to myself that ability... The Spike in the meantime loses half of his charge and (for hypotesis) through that Spike my absolute Store rate is "just" the 50% of my health, but to me is meaningless because I can't store more than 20-30% without die. An Inquisitor is less dumb of myself and they didn't the Spike to decay so much, therefore also if their theory-store speed wasn't less than 100% they can't notice more difficoult to store attributes...therefore the cause must be somewhere else.

Also if uses sacrifice in the "energy balance" is positive, you start with an amount of power and gaining some of it. Much more, on Sel there is just a single Magic System, every Selish magic we saw are just different regional sub-manifestation of the same system... Therefore it's quite impossible to the Dahkor to be end-negative while AonDor, Forgery, Bloodsealing,ecc... are all End-positive. Without counting about that the Dahkor like all the others sub-type is fueled by an outsider source, the Dor.

I have to be honest, I don't think the "knife" is something different from a metaphor...something like a cognitive reflection of the ability of the Vessel to hurt something/someone or some dedicated Splinter of itself (like a Shardblade).... If I remember right, we saw that knife in action and it didn't anything more than cut from the cognitive to the physical (some in common to the Shardblade's cutting between realms ability).

I don't rememeber if one of Dalinar's vision had Tanavast in his form, or if He always used some "dummy/actor" to give his own messages.

But Dakhor magic is end-positive :S

The only Vessel's descriptions are of R&P's Vessels...If you talk about the "orginal vessels" only Ati and Leras both in SH and HOA (very few words of both)

Probabily it's possible but more hard because an Allomancer is already filled with Preservation Investiture. Remember that Investiture interfers with other Investiture, much more if the Investiture and Magic System are from different "Sets" (different worlds) Now I can't search it, but there is a WoB about a child from a Nalthis and Scadrial power and with the child born with a bit of Preservation and a bit of Endowment...strange thing may happen to him.

The problem is that a Feruchemist has no limit to his Speed Storage, we saw people store ALL their attributes at once... you can't go further. Maybe the Inquisitors can't store too much because they have "imperfect" Feruchemy's power (due the Decay) or their peculiar anatomy (being not exactly an Human were you try to store Human Trait may have some kind of problem I suppose)

Probably Nightblood on Roshar would develop some power unrealated by the Surges.. Something more Awekening (or Endowment) related. In the same way I think the Seon would develp (on Roshar) some AonDor relate effect (maybe they may actuallizate their Aon to give its effect) much like be used as a "bridge" to performe Selish Magic with Stormlight.

This may be an Idea but for example we don't know if the Heralds have the same "side powers" than a KR. The Heralds recive their powers trough the Honorblade, I don't think they develop the side effects of a KR and much more they left their Honorblades and actually they probably haven't any Surge powers. PS: There was some theory about "you have to be in touch with an Honorblade to gain its surges", Did we discovered more about ? Because the Honorblades seem to work without altering the Holder deeply while the Nahel Bond develops a deep change in both Human and Spren

Probably the generic Shard no, but we saw how that specific God Metal carry a "Stealth ability" with itself... Bleeder may be invisible to Harmony's Hemalurgic sense trought that Spike... Maybe this "Invasion" is made possible only because That-Shard's God Metal have the ability to hide itself (and it's something that push me away from Odium to be honest, more near to Autonomy)

durallumin if you are a fullborn may be used to compound faster... but unless you want to compound very fast Durallumin itself it's something impossible to a twinborn
