The Kandra's blessing of Presence negates Ruins control somewhat (This as one of TenSoons blessings and the reason he wasn't as easily controlled despite having 4 spikes) But other than that one type and the number of spikes I don't think there's any difference

Given everything we know about allomancy I think that's a fairly safe assumption to make, there's no logical reason whatsoever that the metal burn rate would be dependent upon the time elapsing outside of the bubble. Something like that, I doubt it would be particularly useful, be more suited for Cadmium than Bendalloy.

Both the metal and the allomancer would be inside the time bubble.

I suspect the second, the former would be getting more power out of the metal, and also is the opposite of how Duralumin usually affects a metal burn, if Wayne flares his Bendalloy it's not going to last for a longer time is it? I don't have alloy with me now but I'm pretty sure he does flare it at one point and everything outside slows down more so that's definitely evidence for the second.

Being able to hide from lifesense would be pretty useful to Siri, as would being able to remove toxins and unwanted investiture, I'm pretty sure anyone would be happier knowing that they don't have to worry about poisons. Marasi's abilities are useful, they are a pivotal point in the book, however contrived it may feel and there are certainly other useful applications for the ability if she chose to take advantage of them. If Sarene were actually invested that would have actually been helpful, she could have done a lot better in a fight and Hrathen might not have needed to die, her being tricked is an example of someone suffering the consequences of Investiture without actually being Invested, showing if anything that even the minor consequences of investitures can apply just as easily to someone without it. The magic from illness (Silence Divine IIRC) gives a benefit to those suffering, without the magic they'd still be just as sick, except not able to fly. Being able to completely seal a wound over would be pretty useful to a surgeon, even if it's temporary, I can think of one situation where one of Lirin's patients might not have died of blood loss if he could.

That's not really exploiting a weakness in most of those situations, Vin beating Zane is arguably the only real exploit and even that's not so much a weakness as it is an oversight, if Zane wasn't using Atium he would've lost the fight long before and if not still would have fallen for the feint. Yes people can be useful without investiture but give any of those people pretty much any type of investiture bar Hemalurgy and it would only help them.

I had the same problem when I read it, particularly since if I was Alethi I'd want to be an artifabrian But then again as long as you're not in a Vorin culture you can still learn any of them

It's possible that whatever Lerasium steals is the one thing Atium can't steal, kindof like the mists can act as any allomantic metal except for Atium.

You could reach near light speed with that method but you still wouldn't be able to exceed it, and as you pointed out you'd kill the coinshots. The current preailing opinions on FTL travel mostly involve time bubbles of some form.

It's worth noting that just because D/N don't add power to the metal doesn't mean that bursting a burst wouldn't do anything, as Brandon said when you compress that power to an instant it can become infinitely strong, if say bursting caused a metal to burn in 1/100th of the normal burn time that would make it 100x stronger, if you bursted that burst then you could compress the time even further to 1/10000th of the normal time for 10,000 times the strength.

I just imagined it stealing one specific albeit incredibly useful trait, although there is a case for it decaying less as well, given that Atium is used up so quickly in allomancy Lerasium should do the opposite, then again Lerasium burns instantly in allomancy so i guess that might not carry over. I was thinking something along the line of stealing fortune would be sufficiently awesome.

He was taking advisement from Breeze, black was just getting too monotonous.

I imagine you could still spike the abilities without getting the spren, spiking a Metalborn doesn't give you a piece of Lerasium, it just gives you the spiritual connection which allows you to utilize the ability.

The fake Atium would have to be invested with Marshes feruchemical age for him to compound with it, you couldn't store an attribute in a metalmind, then burn some random other metal source to compound I'd see it more as Marsh just not depleting his feruchemical charge when in the Mists.

Well Jedi foresight seems to be more instinctive than visual most of the time, probably more like Vin's shadow split when she's fighting Zane, just a single split right before the event, rather than a continual stream of thousands of shadows.

Hmm, I do kindof see your point here, I think I'm just stubbornly holding to my initial perception at this point I just can't get over feeling that since it's in a Rithmatist library that that is the intended audience, it's not in the church library or anything

He's specifically said that he tries to work around thermodynamics but he still makes his magic obey thermodynamics, that's why we have the whole power of creation thing, the energy to run magic doesn't come from nowhere, in the cosmere it is an open system, not closed like our universe, so it still is completely in line with thermodynamics. Sure it could just have a low rate of decay, but that's still decay which puts feruchemy as end-negative, directly against what we know of it from WoB.

I agree that it's a human agent, but I was thinking more along the lines of the potential rithmatist to be, in picking a vessel for the shadowblaze to bind it to them, granting rithmatic powers.

Yes but that's only when you compound it, which makes more sense for temporal relocation really, if it were really just a charge then it shouldn't matter how much you tap at once, you shouldn't just get 1 for 1 you should be able to compound without energy loss if each time you store it always just becomes an identical charge, then the rate of storage doesn't matter, and the rate of tapping shouldn't matter. But if it were end-neutral then there shouldn't be any decay over time if you just try to get back 1 for 1, but as per the second law there has to be a decay over time, unless it doesn't experience any time.

Those in charge of the binding? How do you mean?

because a 1% change in entropy to something with 10^25 joules of energy is much more easily observable that a 1% change in something with just 1 Joule, there will be some noticeable entropy to the statue, however that is reflected. More importantly if entropy is involved in feruchemy in any way at all, it ceases to be an end-negative system. EDIT: Same reason the amount of metal matters, you need a gateway to access the power and once you go through the feruchemical charge that gateway can't remain open.

Yeah I don't see this as being likely to happen, especially since all the other magic systems would need an equal mirroring of all 16 Shards' natures.

Yeah I read the bindagent as being the potential rithmatist, the fourth entity removed part is interesting though, removed from what? It's been established that rithmatists have varying religious beliefs so it can't be anything too religious in nature.

The energy in a proton is miniscule compared to a filled metalmind, sure complete decay might take ages but it would still noticeably decay in some respect within an observable span.

It should also be pointed out that without a temporal aspect to it, feruchemy would still need to deal with entropy, feruchemical charges should decay over time, but they don't. I'd say it'd effect the length of time you could burn it, just like having a larger metal reserve.
