Finishing Random Twinborn Combinations

[Lopens Tenth Cousin he/him]

I was very, very late to this party. The last post in the main thread was on March 11, 2024, which was over a year ago. I ended up reading through all of the thread and I liked the idea. I almost continued it, but I decided to get new people interested, it would be better if a new one was made. The original thread was made by @Koloss17 right here. (I got permission to post from them before I posted)

I will do my best to not repost any of the combos that were found on that thread, so if you want to review those options I highly encourage looking through that thread if you have time. Additionally, @Atlas333 was kind enough to make a spreadsheet with already done Twinborn Combos right here:

https://docs.google.com/spreadsheets/d/1_Xbhypr0ihq1A3rLzmvr0wcHL-TKnm81m6LIyK9lMqQ/edit#gid=0

Green highlighted squares are Compounders, and the blue highlighted squares have been done (some are blank because there were no great names I assume) Atlas can correct me if I'm wrong.

The original thread was any Twinborn combinations of the 16 base metals and Atium included because why not. It was randomly determined and posted each day until it kinda died. I can't promise to post each day, but I can post pretty consistently (also if I don't post one day feel free to post I don't have to do everything). There will be a discussion of the individual powers, and how they could possibly synergize, with possible resonances, a suggested name, and an arbitrary rating.

That being said, I want to do the first combo today, starting off with combo #1 of this thread:
 

A-Duralumin/F-Copper

(Enhances Current Metal Burned / Stores Memories)

Allomantic duralumin is interesting in the fact that the burst of power is useless without other metals to enhance. However, in the previous thread there was discussion pertaining to whether or not duralumin would provide a burst of power in relation to other MoI - most relevantly Feruchemy. So, while a duralumin gnat, there may be potential benefits when combined with feruchemical abilities.

That being said, F-Copper stores memories - exactly the same as they were when you first received them, but with degradation for however long it was out of the metalmind. The memories are impeccable - but you don't notice anything with enhanced perception (AFAIK).

From this, I have two different conjectures:

1. Burning duralumin while Tapping Copper will enhance the memories to the point where you will notice a lot more than typical but it will degrade the memory at a higher rate. Other mental benefits could be prevalent, such as in this WOB (Talks about Copper Compounding, but duralumin could do something similar):

   1) What benefit does Compounding copper get? Exceptionally clear and detailed memories? Memories that can be split into a new coppermind while still remaining in the Feruchemist's mind? Something else?

   2) How does Feruchemical luck work? If a chromium Compounder tried his hand at day trading on the stock market, what would happen? Would it make him choose stocks that were coincidentally going to go up anyway? Would it change stock prices by altering the world around him? Would it fail because the required scale of action is too large? Something else?

   So, I've said before that I want to hold off on talking about different forms of compounding and types of twinborn until I can address them in the series. So I'll have to RAFO the first two.

   17th Shard Forum Q&A (Sept. 27, 2012)

   
    
2. Burning duralumin while Tapping Copper causes the memory to flash by too fast for you to really make any sense of it and it degrades the memory majorly. This is probably more likely to happen than #1, but I think #1 would be cooler so I'm going to go with that.

I'm just going to go ahead and say that more details would be able to be noticed.

 

Resonance: These are hard to define but I will do my best - I think an increased ability to process information during explosive events or normally deep perspective thoughts

Name: I'm going to go with Mindburst, seeing as it is similar to Nicroburst although to do with memories.

Rating: This twinborn wouldn't be the most useful in combat, but for a detective or some similar occupation it could be pretty useful (if my theory is true) so 7/10 as it would be useful in daily life. Unless my theory is wrong, then it would be a 3/10, as it wouldn't be better than having just F-Copper, but it would be better than just having A-Duralumin.

This is really cool! I really liked the original series, and I'm glad it was revived! Could you talk about Iron Compounding? I feel like its a bit underated. I would be very happy to see someone talk about its city leveling powers.

Well, I mean, you're still limited by Metalmind storage (how much you can realistically carry on you) as well as needing to Push in order to not obliterate yourself with its full power (requiring Hemalurgy or an Unsealed Metalmind). 

Plus, the range of your Pushing is limited by your Allomantic strength, so even if you could hit with enormous force your range of effect may still be very finite. 

You could still level a city with it, but it would take a lot of work to accomplish with this powerset.

2 things. 1, really big metalminds. 2, don't hate me, *pulling

I dont think that metalmind storage will really mess you up on this one. Iron is cheap and plentiful. We see Wax level a building and burst through his floor without compounding. If Wax weighs 200lbs and he stores 30% of his weight all the time... then in the 16 hours of him being awake he has amassed almost 3.5million lb seconds (a made up unit but if he tapped it all in all second I assume that would be 60lbsx 16 hours × 60 minutes × 60 seconds right?)  

And he did that day after day after day storing into bracers alone.  

This combo is terrifying and nearly blackhole worthy, especially if you got a buddy who was a nicrosil allomancer who was willing to sacrifice themselves as you burn instantly all of your metalminds at once.

True, true. That could solve the storage issue.

So, pulling a Wayne, essentially?

Wouldn't your Pulling range be limited still? You could topple a skyscraper with ease, sure, but if your Allomancy only goes to a range of like a few hundred feet at most I don't know if that is city-collapsing power.

Maybe if you were to burn loads of iron at once with the help of a Nicroburst (or Harmonium) it would be more feasible. If your giant Ironmind pierced your body you might be able to Burn the non-Invested portions for extreme Allomancy and the tap the rest for mass.

Range is also dependant on how large the piece of metal is. 

I feel like so many PoV are from coinshots who are pushing on small objects, but the larger the object, or the more metal in it, the further away you can see it. 

To topple a city this Deader (the MAG and my favorite term for iron compounder) really doesnt have to pull down a whole building at once. Simply targeting the support beams at the base of each building should be enough. And if Waxes braces (which I dont remember being described as full at any point) were able to give him the weight to topple a building I dont think a compounder would really need to have some massive storage space. 

Just think of Miles and his compounding... he had metalminds throughout his body but he wasn't needing to wear a whole suit of armor or anything and he was compounding to the point of savantism. 

Lurchers commonly wear large plates on themselves to pull metal toward for protection. This could easily double as a metalmind for them and I would bet would offer more than enough storage to cripple a city. Just look at how much the bands of mourning had and they were split between all metals. Marasi went mach 1 for a few seconds with 1/16th of a spear head she was able to hold in her hand. 

So I really really don't think a Deader who is compounding what is probably the cheapest and easiest metal to get is going to have storage issues. 

I think setting up on a city street and targeting the footings of skyscrapers could easily result in a toppled mess. And if you switch to storing rather quickly you can probably pull yourself to safety while the support beams are all busting up and the buildings start to topple. 

Maybe not leveling a city in one moment but I could see a cinematic scene of this Deader monster walking and causing between buildings only to see the road crack beneath him and the sounds of popping support beams and crumbling concrete. Then he slingshots himself forward with a giant pull a bit higher on each of them and stores his weight (like Spiderman with the double website slingshot). He becomes massive again mid air and the last tugs to bring the buildings down before landing at featherweight, tapping again, cracking the street again and wrecking the next buildings in line. 

Certainly the storage potential is there given our examples. Normal everyday storage for iron doesnt fill up Wax's bracers. And the amount of potential weight for a single second of use from a non compounder is millions of pounds in a single 16 hour day of storage at even 30% of body weight. 

Edit: 

Just wanted to throw in the epic wall running an iron compounder could do too. Store weight and little pulls along the supports... you could literally climb walls and crawl around on ceilings like Spiderman too which would be dope. As the building is crumbling your running / pulling yourself along it only to jump at the last minute and store more weight to float and take zero fall damage. 

While perhaps only multiple building leveling strength instead of full city toppling power, this combo is one of my absolute favorites for ultimate bad guy cinematic effects.

Lol I love how we're already getting super meta. I'll get to it I promise but since...

I rolled a compounder, I'm going to do two (especially because it is a compounder we've already seen), and not do Iron compounding today, sorry.

Twinborn Combo #2:

A-Gold/F-Gold

(Shows past self / Stores Health)

So allomantic gold allows you to see possible past versions of yourself simultaneously, which would be a very weird experience, especially the first time. Although it would be great for a philosopher and for self reflection, it's not that useful for combat situations.

Feruchemical gold, on the other hand, is very useful, with the storing of Health to use to heal yourself. Realmatic theory doohickies below (slight SA spoilers(Not WaT)):

Spoiler

When you tap gold, you are healing your Physical self based on your Spiritual self (ideal self) that is influenced by your Cognitive self (group perception of your self). This could lead to some very interesting possibilities pertaining to healing, as it could achieve feats similar to that performed by THE Lopen, where since he didn't perceive his missing arm as a part of him, it grew back once he obtained Spiritual Healing. Changing your perception of yourself would be nigh impossible for the mostly sane person, but theoretically if you perceived yourself as having four arms, for example, you could grow two extra arms using the stored Health. 

Additionally, Brandon has said that transgender people would transform into their perceived gender using Spiritual Healing, changing their Physical self into someone that relates more closely to their Cognitive self.

Compounding these two abilities would be insane, as we have seen from Miles Hundredlives and the Lord Ruler. Basically, while you have metalminds, you're really never gonna die. 

Resonance: Due to the nature of compounding, resonances rarely occur due to over-reliance on the feruchemical power, but if both powers were developed significantly, I would think the resonance would be somewhere along the lines of being able to heal scars better (as it's a form of your past self, but it goes with your healing power)

Name: Atlas said Immortal on the document, and I think that name fits mostly, but as they can still die of old age I think I'll go with Invincible (I'm not ever going to rewrite one of Atlas' names without their permission)

Rating: 8.5/10, due to the fact that although it is insane, it is likely to lead you down the path of savantism and cause issues.

 

Twinborn Combo #3:

Can't believe that I got F-Gold twice in one day but whatever.

A-Pewter/F-Gold

(Increases Physical Abilities / Stores Health)

Now this, this could be insane, as A-Pewter, although it increases strength, speed, and temperature resistance, also increases the time you can stay standing with injuries. I don't know if it would be considered "Healing," as it's more like prolonging injury, but you may be able to store this inside of a gold metalmind in order to pull on it on times where you're low on Feruchemical health. Basically, with this combo, you'd be insane in close range fights, and would be able to shrug off most wounds that would be mortal wounds on most people. 

Resonance: I think the resonance to this would be an increased higher health capacity, similar to that of someone with a Nalthian Biochromatic Breath.

Name: Atlas and the MAG (Mistborn Adventure Game) agree on the name Bruteblood, and that seems to be the general consensus of the name.

Rating: 7/10. Also absolutely insane for a fighter (particularly in hand to hand), but probably will lead to savantism.

 

Also for future reference, I'm open for discussion on any of these things that you disagree with or want to expand upon.

I actually think that for combat this bruteblood ranks higher than the immortal. 

Gold compounding is insanely powerful and Miles has shown us well the reason for that. But in everyday life I think that it is just too expensive and not worth it... I dont like pain personally and I dont do anything in my life that would require me to heal through getting shot in the face most of the time. 

A-pewter on its own is a 7/10 for my purposes.  Its a ramped up Captain America build on a timecrunch. Offering it F-gold as a buffer makes it even scarier. 

My thoughts on infinite healing are more just a matter of we have seen how busted it all is with no modern day armor and protections. But what happens when you add in some sort of armoring to protect the vitals that likely cost the most healing anyway? Pewter will already dampen the blow and if you can stop yourself from having those vitals punctured then you can really start to ramp up the power scaling. 

And it should be noted that this build doesn't just limit you to melee combat. How much more protection could a pewterarm move around well in than not? They could probably function fairly well in ballistics plating along their legs and arms as well moving as quickly as a normal man with no armoring... and they could definately carry and handle far larger weapons onto the battlefield... the F gold they would use would be almost exclusively applied to shots that just happen to land on unarmored areas... 

If you can wear enough armor to cover up 90% of shots you would take and allow the pewter toughness to brute your way past the blunt force trauma of those shots landing on that plate... even a small tapping of gold could heal a ton of those issues. And being able to carry around far larger weaponry you really are able to function like someone with powerarmor-lite. 

I choose that over gold compounding because it offers so much more flexibility in the build. And if your not fighting... then A pewter is one of the most beneficial abilities in the entire cosmere for day to day life of a working man IMHO. 

[Lopens Tenth Cousin he/him]

@DoctaDajmanyeah I agree with the combat applications, but the rating isn't based on that. It is the cost -benefit analysis based on how much better it is than just having one power or the other. I do agree that Pewter gold would be better for most combat situations (you don't need to heal something if you can just avoid it), but unless a gold compounder runs out of gold they're essentially unkillable. Maybe not as dangerous, but less likely to die.

Yeah I can see that. I will have to maintain my feelings that Allomantic gold drags it down and Allomantic pewter lifts the other. My rating would be the opposite of yours for that alone. Even non combat I dont see much use of looking at who I could have been in another universe, but a pewter is always needed. 

And if combat isn't being counted then F gold on its own is likely more than enough. 

Being immune to trauma and acute illness doesnt save you from death entirely, Miles still got old. 

Having A-pewter to help take the edge off of storing in goldminds and not facing the risk of a traumatic death through constant combat makes the non compounded ability set even better. Every part of an active lifestyle would gain bonus points from pewter allomancy, look at Vin when dancing at the balls even. Doing yardwork or even moving furniture would be far easier as a pewterarm. If you are not constantly throwing yourself into traumatic situations then typical F gold is perfect for healing through the odd car accident or mugging. Spend a couple hours every day storing a little bit and that 2 weeks you would have have the flu gets cut down to 10 seconds if you want to fast track it. The odd knife cut... healed instantly. 

Compounding gold is only really beneficial if you are combat centric. Typical f gold and A pewter are great 90% of the time.

Yes, I know, it was something I addressed in the naming portion. However, in space age cosmere (or if you're just a worldhopper) gold compounding would be amazing due to the fact that the thing scientists are most worried about when interacting with other forms of complex life is the diseases we do not have a resistance to - with gold compounding, you would essentially have an unbeatable immune system, and it would allow you to study things that are normally too dangerous otherwise (e.g. the First of the Sun or maybe even possibly Sel's subastral)

Edit: I'm also just a huge nerd and wish I could worldhop and be immune to most of the possible negative effects.

Essentially. Or sometimes multiple names would be suggested without a clear consensus on which was better (if I'm remembering right)

[Lopens Tenth Cousin he/him]

Okay, today is an interesting one. (don't get too excited @Koloss17)...

Twinborn Combo #4

A-Atium / F-Tin

(See the near-future of others / Stores senses)

Allomantic Atium, as we saw it in the books has already been retconned, as Brandon Stated that the nature of God Metals should've been able to be used by everybody. In the Coppermind, it states:

Quote

Despite its name, the metal known as atium is not actually the pure form of Ruin's God Metal. Instead, atium is an alloy of electrum and that pure God Metal.

In other words, they are essentially an electrum misting, but I digress. Burning Atium gives you the ability to see into the near-future of those around you and of objects around you. It does this in the form of "shadows" that are perceivable to the user. Since the metal doesn't exist in real life, and it was rare back then, nonexistent around the Wax and Wayne series, I think you're going to have a rough time being this misting.

Feruchemical Tin stores senses - however, not necessarily the 5 basic senses that people think of. There have been multiple WoB on the subject:

Quote

BartimaeusTrilogyFan

Can Feruchemists store more than the five ‘traditional’ senses, and does Allomantic tin enhance more than the traditional five senses?

Brandon Sanderson

More is possible.

Herowannabe

I recently picked up the Mistborn Adventure game and am loving it. I made a character who is a blind Mistborn because hey, I thought it would make for some interesting possibilities. As I understand Allomancy, he can hear/sense well enough to get around with Tin, plus even though he's blind he can still "see" steel lines (like the inquisitors), and I assume Atium would work the same way- that is, he could still "see" Atium shadows. Please correct me if I'm wrong.

Brandon Sanderson

No, you're right. That works. He'd have to burn metals a LOT though. It might warp him a little.

Can Feruchemical tin store Allomantically granted senses like bronze sense?

Brandon Sanderson

Possible.

General Signed Books 2018 (Feb. 8, 2018)

There's more, but I keep getting distracted. Therefore, you should be able to store proprioception (feeling of body part location), nocioception (sense of pain), and Allomantic abilities (like Bronze pulses and Steelsight). 

So, I believe you would be able to store your ability to see shadows. Not your ability to perceive them, nor your ability to use Fortune at that moment, in which case would make this combo slightly useless - unless you can also store the ability to "feel" incoming attacks. You would be able to "see" the shadows at any time, but you wouldn't be able to see them have the future echo like when Atium is burned normally. If you can store the ability to feel incoming attacks, then you might be able to become insane at dodging (again, if you can find Atium)

Resonance: I think the resonance between these two metals would be an increased sense of the location of others - When burning Atium you can dodge attacks that come from behind when you don't necessarily "see" the shadows but you "feel" them.  It wouldn't be too overpowered, but more like a more advanced form of when you can feel somebody standing behind you.

Name: there is a scientific thing called Pareidolia where your mind creates shadows and patterns because your bored, and I feel like you would become extremely jumpy with this combo, so possibly Paranoid.

Rating: Honestly, mostly because it would be extremely difficult to get Atium (in real life impossible), I would go with 4/10 in world, 2/10 out of it. F-Tin is still extremely useful, but Atium is too rare to really cause much of a difference. If you had a supply of Atium, I would go with 5/10 if you could feel incoming attacks (although I think just burning Atium would be more useful)

 

 

Edit: If you pulled upon already stored senses, and burned Atium, would you be able to have it so you could "hear" the shadows, see them better, or maybe even be able to "feel" them even though they're ethereal, thereby giving you an edge, especially upon other Atium mistings?

Twinborn Combo #4

A-Atium / F-Tin

(See the near-future of others / Stores senses)

Allomantic Atium, as we saw it in the books has already been retconned, as Brandon Stated that the nature of God Metals should've been able to be used by everybody. In the Coppermind, it states:

In other words, they are essentially an electrum misting, but I digress. Burning Atium gives you the ability to see into the near-future of those around you and of objects around you. It does this in the form of "shadows" that are perceivable to the user. Since the metal doesn't exist in real life, and it was rare back then, nonexistent around the Wax and Wayne series, I think you're going to have a rough time being this misting.

Feruchemical Tin stores senses - however, not necessarily the 5 basic senses that people think of. There have been multiple WoB on the subject:

There's more, but I keep getting distracted. Therefore, you should be able to store proprioception (feeling of body part location), nocioception (sense of pain), and Allomantic abilities (like Bronze pulses and Steelsight). 

So, I believe you would be able to store your ability to see shadows. Not your ability to perceive them, nor your ability to use Fortune at that moment, in which case would make this combo slightly useless - unless you can also store the ability to "feel" incoming attacks. You would be able to "see" the shadows at any time, but you wouldn't be able to see them have the future echo like when Atium is burned normally. If you can store the ability to feel incoming attacks, then you might be able to become insane at dodging (again, if you can find Atium)

I agree with your assessment of 2/10. Atium is so rare that using it to store the shadows without any added benefit is a complete waste of time and a fortune... 

Sure you can store it but without the benefits is atium even really atium?  

Talking about how electrum mistings are who we saw use atium in the past thanks to the retcon... this may be a far better use of the combo. 

Electrum doesnt have the same mental enhancements that atium does and it is going to be far far cheaper and more available than atium. Not that I want to push past the one combo at a time but you could almost copy and paste this one over and give it a higher ranking than the atium one. 

The shadows are going to be largely ignored for these combos imo and they are more useful for pseudo dark vision. In a pitch black warehouse, cave, or even diving without goggles or light?  Tap into your stored spiritual vision and you can see. 

Electrum just makes that vision so so much more available for use compared to atium. Furthermore, atium being burnt only to store it would be an utter waste of one of the most valuable resources in all of the cosmere. 

Not to mention that electrum burns longer than atium and the only amount of time you could store is equal to the total time of a burn. 

For those reasons I could see electrum / tin being ranked higher than atium / tin because it is easier to fulfill the single trick that this pony is with electrum as well as offering more benefit for far less cost thanks to electrum burning for longer than atium and being far cheaper and easier to aquire. 

Atiums rarity may make it a 0.1/10 in my book vs electrum combo being closer to the 4-5 / 10 range.

WOOOO F-TIN!!!

I will say that it can be a little confusing on whether or not you could store the atium shadows. It relies on fortune, which F-tin obviously can't store. So if the shadows were stored, would you be getting that fortune? Conversely, if you had F-chromium instead of F-tin, would you see the shadows? I don't really know the answer.

However, for selfish reasons, I think it should be able to be stored under F-tin.

If I remember correctly everything has a shadow and not just people. Even if you got a different version of inquisitor (god vision according to Kel in TLM) sight from storing gold/ electrum / atium / malatium and the future / past shadows were not present this combo would be valuable.

Yes these options WOULD be better, but IIRC, the only metal that showed object shadows was Atium(and possibly malatium). All the other "Shadow" metals showed the shadows of people

Here is a WoB that sheds some light. 

Spoiler

Herowannabe

What happens when a blind person burns Gold- especially of he "sees" a version of himself that isn't blind? Can he see the other version or just hear/feel/sense him? What about the other version, can it see things? Could a blind person use gold in this way to see the world around him?

Brandon Sanderson

A blind person would indeed sense these things, but not have the vision with the eyes. In the same way that a blind person still dreams, but doesn't "See" in them. (As I understand it.) I'd suggest talking to someone who is blind and getting their take on how this would work.

/r/fantasy AMA 2013 (April 15, 2013)

As I read this I am led to believe that a gold burning blind person could sense the world around them with the gold burning in a way a blind person dreams.  

That makes me think that sensing the world around you while burning gold would be effected in whatever way you dream and sense / see things. 

My head cannon following that is that all 4 of those metals offer a sort of spiritual vision of the world around them.

In the original post it said that there were 289 possible combinations this is slightly wrong because we know combining a god metal with one of the basic metals makes a new metal and the god metals we know of are atuim, lerasium, raysium, trillium, honors metal mixed with Cutavations metal, and honors and Cutavations metals separate that's 7 if you combined each of those with the bace 16 you get 112 metals then to get twinborn combinations you multiply it by its self which gives us 12,544 possible combinations plus what ever other gods have metals like harmony but his metal is as of right now not burn able due to it exploding if it touches water. Brandon also said that if a shard switches hands that shard has a new metal so the shard Preservation has had 3 metals lerasium, Kelsiers metal, and vins and is know mix with ruin to make harmonium which also make raysium and honors metal no longer because they are one.

Yes, however, like in the post for today, it seems that the metal you are an allomancer of will give you the abilities of it alloyed with godmetals as well, which isn't more combinations, just more variety for the combinations. Personally, I think that an Electrum Ferring would also be able to use the abilities that Atium gave feruchemists, and that there is the exact same number, just effects will change depending on if you store in that metal alloyed with a godmetal.

[The Grand Jesk]

We know that malatium is a gold and atium alloy and if you look on the malatium page it says that you can snap and be a malatium misting so with this i think that you can also be a misting with a metal from another shard, alloy or not

Yes, in the original series it was like that, but afterwards Brandon retconned it so then Atium would fit more with how godmetals should work. WoB:

Spoiler

AAKS

My understanding is that Brandon thinks it is a plothole that lerasium can be burned by Scadrian (regardless of if they are Mistings/Mistborn) but atium can't.

His solution is to retcon the Pits to naturally produce an atium/electrum alloy, presumably by the design of Preservation. Therefore we don't know what pure atium looks like or does when used in any magic.

Peter Ahlstrom

We do know what it does. It’s on the Allomancy poster, and the effect appeared one time at the end of Hero of Ages.

LewsTherinTelescope

Interesting. Do you know if he had already conceived the retcon by the time the poster was written, or if that line about pure atium just turned out to fit really well retroactively?

Peter Ahlstrom

The retcon is way older than a lot of people assume.

LewsTherinTelescope

Does this mean he had it in mind by the time Hero of Ages released (since the first public version of the poster dates to 2008), or just that it's old but not sure exactly how old?

Peter Ahlstrom

Remember that what's in the books is filtered through the understanding of the characters. So even if Brandon planned it from the beginning, if the characters didn't know about it, it's not going to come out in the book.

And see this thread reply from 2009.

Footnote: The link is to a post on the Timewaster's Guide forums, where Peter responds to someone asking about whether atium is an alloy by saying he now knows enough to confirm or deny the theory, but is not allowed to.
General Reddit 2022 (Dec. 4, 2022)

So: in the first series, there were malatium mistings, but they were really gold mistings that used the malatium alloy

[The Grand Jesk]

Ok Sweet but does that mean that like how anyone can burn lerasium can any one burn any god metal?

It is very vague. Possibly only allomancers can burn any god metal, but possibly normal people can too. WoB:

We know that any person can burn lerasium. Are there other God Metals that any person can burn?

Yes.

Twinborn Combo #5

A-Brass/F-Tin

(Soothes emotions / Store senses)

Allomantic Brass is the ability to soothe people's emotions - to dampen specific emotions and make someone more susceptible to suggestion. This would make you seem to be the best friend ever! (unless one of the many, many, many, many, people you've manipulated finds out and gets mad)

Feruchemical Tin, as I described yesterday (still don't know what the chances are that I got it again) stores senses.

This combo seems almost identical to the Mindwhisper from the previous thread - but with brass. Using stored sight to be able to perceive people's body language to better use your allomancy was suggested, and I agree with that.

Resonance: Possibly an enhanced perception when somebody is feeling negative emotions - not which emotions, just emotions.

Name: I was thinking Reassurer - the soothing does the reassuring and the F-tin provides the context to the soother.

Rating: I will go with 8/10, because having enhanced vision while soothing seems like it will provide major benefits.
