Can you use A-Duralumin to drain your metalmind realy fast?

[Sythrin]

Can you drain that way a metalmind realy fast, without to loose access investiture like if you would drain it manifold?

And can you do tge opposite? Fill a metalmind realy fast and drain yourself of something to the extreme?

Like make yourself temporarily extremly light (maybe phasing is possible because of the concentration of mass?), make yourself extremly depresseed and so on?

While a Feruchemist can only store attributes at a reasonable rate, there isn't an upper limit of how much they are able to tap at any given time.

Yeah sazed does this a few times in final empire where he taps and stores a lot of strength. the quote is from the coppermind. the only reason a feruchemist can only store at a reasonable rate is because they cant store 100% strength without dying due to all of their mussels like the ones in their heart being too weak. But it is possible to store all of your weight. This wont make you phase through something because feruchemial weight has no effect on mass.

Ok. But can you drain a metalmjnd faster without loosing access investiture?

For example goldminds can be deained faster to make yourself quickheal or heal normally impossible wounds. But you loose access health that way. Could A-Duralumin help?

This one is hard.  We dont have numbers so take these with a grain of salt. There are diminishing returns when tapping beyond what you stored.  

If you weigh 200lbs and store 50% of your weight then that is 100lbs. You will not lose any of that to diminishing returns so long as you tap it in that same increment. 

1 minutes at 50% storage is 6,000lbs 1 hour is 360,000. 

The only way you dont lose any of this is if you tap it at a rate that would stretch it out for an hour or more. If you choose to tap it all at once some of that weight will be lost in the conversion. We dont know how much... say you lose 20%.  Instead of weighing 360,200lbs for 1 second you would only weigh 288,200lbs for 1 sec. 

Again we dont know how much you lose but we know you will lose something. 

As for duralumin and its uses here... I dont know 100% but I would guess that those allomantic metals would work on metalminds. If you were tapping a ring and used duralumin you may be forced to use it all with no loss of attribute... but then you are losing all excess anyways because the entire metalmind would empty. 

I believe the same with nicrosil vs a feruchemist and chromium against a feruchemist. The metalmind in use actively will be wiped clean. 

In golds case, you have enough health to heal 5 bullet wounds over a few hours. You want that healing instantly? Maybe you only heal 3 bullet wounds from what is lost. Using duralumin while tapping will make sure you lose all health, 5 bullet wounds worth, no matter how many holes you are trying to patch up... 

Using larger amounts quickly comes with a promise of waste right? But some waste while you rapidly titrate the amount of attribute you need to use could still be far more advantageous than using duralumin to make sure yoh dont lose any of your storage if it ends up being way overkill on use.

I suspect feruchemical steel, storing physical speed, might let these sort of processes to store/tap faster, but I have no idea how to avoid losing energy.

[AltonicKeys he/him]

For the Allomantic duralumin bit, I think it's kinda iffy. Its stated purpose is to enhance and burst the current metal(s) being burned by the same allomancer.

But at the same time, WOBs about nicrosil burning and duralumin with surges.

Questioner

Nicrosil and chromium, do those have any interaction with people using Feruchemy, or other Investiture in general? Leechers or Nicrobursts.

Brandon Sanderson

Could you use those on Feruchemists? You should be able to, yes.

Questioner

Would that only work while they're tapping it?

Brandon Sanderson

If it's active Investiture, probably yes. You'd probably need it to be kinetic Investiture in order for them to do anything about it.

If a person had the power of Mistborn and other powers like Surges, could he use duralumin to power the Surges?

Brandon Sanderson

This is possible.

Skyward Houston signing (Nov. 19, 2018)

So while Sanderson says that it's possible, and you can use it, at the same time he doesn't elaborate on exactly how. We don't see duralumin used on anything but other A-metals, and the same goes for A-Nicrosil. Even if this would 'work,' I feel like you'd still get that discounted attribute and power loss from the speed.

F-Nicrosil, however... That might have some potential.
Though it's not explained, not even understood by the users, the general gist of it is that you can store investiture. Coppermind states someone storing it would be storing their ability to use investiture. The example used is that a Feruchemist storing their Feruchemy abilities would lose their powers, and someone else tapping the metalmind would become a temporary full Feruchemist and be able to fill metalminds. 

So. Say you have a full Nicrosilmind and a full Pewtermind. The Nicrosilmind is full of your Pewter ferring powers. You tap Nicrosil and double it, so you're twice as 'able' to use pewter. You tap pewter, at a doubled rate. How much strength would you get out of it? Will you get 4 times a normal rate, since you're double-tapping it twice over? Would you get 2 times strength, but without any power loss, since you're twice as 'able'? 

or What about F-Aluminum, and you tap your Identity as a pewter ferring at a doubled rate? (Would you lose some of that identity due to power loss over time?)

I get that I am asking more questions than I am answering, but I think it's relevant to bring up other Investiture-related shenanigans.

I dont think tapping f-nicrosil allows you to access more investiture. I think it makes you just better at it and have less investiture loss. If you would gain alomantix powers, the force of the metal you burn would be maybe stronger. To the point similar to ancient mistboen. Being able to move metal inside bodies or controling Kandra. And in case of feruchemy probably you loose less investiture when you tap faster.
