Yeah, this is one of those solutions that, had I been writing, I would have ruled as not actually workable. Takes too long, Voldemort or a Death Eater sees the threads and breaks them on general principles, nanotubes don’t actually have enough tensile strength to reasonably slice up everybody at once consistently, and so forth. I pretty much filed any tactical violence plan under “not practical”.
Still, not my story. It’s not out of keeping with the rest of the stuff in HPMOR.
High odds that Voldemort escaped. He’s been extraordinarily hammy this whole time, and he called all the Death Eaters together, killed or crippled a few, and then explained his evil scheme to the hero before giving him a countdown to his inevitable death, while leaving him armed. It seems very plausible that Tom Riddle was tired of Lord Voldemort, and decided to retire him via dramatic massacre. Why make his new body a snaky freak-show, after all?
On the pedantic nitpicker trivia side of things, you don’t have a tank of “oxyacetelene”. An oxy-acetylene rig uses a tank of oxygen, and a tank of acetylene. But Harry is probably not a welder, and neither are the Weasely twins, so nobody involved was equipped to notice the problem.
The volume of the transfiguration makes it negligibly quick; nanotubes have the highest tensile strength of any material and they were not lone tubes, but braided; I’m fairly sure spotting a braided nanowire in the dark is nearly impossible; and the tension transfiguration is what made the slicing consistent. How exactly is it not practical?
I pretty much filed any tactical violence plan under “not practical”.
That’s why you have multiple tactical violence plans running at the same time. Mine had neurotoxin and jets of fluorine. Also, Harry could transfigure a flashbang if he gets noticed, and he reinforces his body with carbon nanotubes for in case he gets shot.
We know for a fact that the Hogwarts wards do not raise an alarm when they should, because they did not detect Draco being under a Blood-Cooling Charm. And we also know that Voldie had a better idea regarding those wards (whether he actually had said wards in place around Draco is debatable, but still, he had the idea).
So I think it’s extremely probable that the wards he has to detect his own death are more efficient than the Hogwarts wards, and he’s currently riding Bella’s body and kicking himself for once more not having just used Avada Kedavra.
Or he and Bella are kicking back on a beach in the Caribbean, drinking alcohol from coconuts and murdering anyone who plays loud music nearby or fails to clean up after their dogs.
The Blood-Cooling Charm was invented for the story specifically to offer a means of murder that didn’t set off the wards until the point of death; furthermore, if a professor (Quirrell) cast it, the wards wouldn’t trigger anyway.
Well, yes, but it had to be believable that Hermione had cast it, therefore we can assume that it would not have triggered the wards even if Quirrel had not cast it.
Me too. I didn’t say this a couple of days ago, owing to a lack of confidence that I now see to have been misguided; but while the nanowire PT solution is reasonable and effective and exactly the sort of thing that a sci-fi fan who fancies themselves clever would come up with, it’s narratively shallow. And I can’t see messily killing thirty-six people as in character for Harry at this moment, however much noise has been made about killing intent. Coming up with creative ways to kill people is one thing; actually going through with it in anger, or even thinking of it when faced with real hostility, is quite another.
(I’m also not totally sure it would work, but that depends on messy materials-science math that I can’t be bothered with right now.)
Lest I be accused of being overly negative, though, the Obliviation bit does have a certain elegant symmetry to it.
And I can’t see messily killing thirty-six people as in character for Harry at this moment
Convenient, is it not, that Harry had the apparent necessity of killing all the Death Eaters?
Good guys only kill when they have to—but somehow, after the heros have nobly declined to kill the bad guys when they aren’t forced to, the cops always manage to get their guns stolen by the criminal, and the good guys get to take them down in self defense anyway.
MoR!Harry’s opposition to killing has always been more of a philosophical objection than an instinctual one, foreshadowed heavily back in chapters 7, 10, and 16. Given the effects of Voldemort’s alterations to his brain during youth, depending on your idea of identity this not the typical situation of confronting the psychological cost of taking life.
Ironically, non-lethal transfiguration was probably available, even if Harry wouldn’t or couldn’t think of it—there’s no restriction to, say, converting people’s blood into propofol or methohexital, for example. That’d be unhealthy even beyond the normal health risks of human transfiguration, but in exchange for its risk of breathing issues and transmutation-related blood-clot-in-brain effects, comes with the benefit of exceptionally fast activity, and the volume required is well within the constraints of the problem. While the Deatheaters are more complicated a problem despite Voldemort calling them useless, there are a handful of other possible solutions that would be less likely immediately lethal. The only person Harry /had/ to maim was Voldemort, and that’s because direct transfiguration would have alerted him.
Given that Harry almost certainly killed Sirius, and probably killed Lucius, and we have a number of chapters left, this may well end up being a narrative complication and a flaw, even if an understandable one.
there’s no restriction to, say, converting people’s blood into propofol or methohexital, for example.
Free transfiguration requires wand contact with the object, right? Seems a little arbitrary at the quantum level, but I think that prevents Harry from just transfiguring someone’s blood from afar.
It’s implied that more experienced wizards and witches can freely transfigure objects at a range, but Harry can’t do that. However, even without Partial Transfiguration, objects that have been joined together can be transmuted as a whole (see chapter 28, with a wand touching one part of an object and converting parts into different components. We’ve also seen transfiguration operate differently on different components of a system. Once Harry has stuck spider-silk between his wand and a Death Eater, he can convert components of the Death Eater as easily as if he were standing next to them.
Harry’s not shown any interest in this sort of biochemistry (the closest we’ve seen is a reference to “knockout gas”, which means he knows less than nothing), and while propofol was well-known in 1992, it’s not referenced in the sort of literature he’s likely to read, he has been trained not to consider transmuting humans, his character isn’t really aligned with less-lethal conversions, and there is a very high complexity penalty to this plan.
There are also some possible volumetric issues. We hadn’t gotten an actual transfiguration rate since chapter 23, where he could only do five cubic centimeters per minute, while it would take about ~15 cubic centimeters of propofol to rapidly sedate this number of Death Eaters. The post-exam chapter gave an update of cubic millimeter “as fast as he can concentrate his will and magic” and “in a fraction of a second”, which is imprecise enough to be useless. He was able to transfigure a unicorn in about an hour and a twelve-year-old’s corpse fast enough to avoid notice, recently, and presuming unicorns are similar in volume to even a small horse he’d need to be moving much faster than 15 cubic centimeters a minute (900 cubic centimeters is less than a liter, a very small shetland pony would operate somewhere in the area of 180-200 liters, so… not sure folk did the math on that one).
But it’s interesting as a thought experiment.
This isn’t the only or even a particularly useful option—Voldemort’s gun could be rigged to fail in a cubic milimeter transfiguration, and to catastrophically fail in a cubic centimeter transfiguration; wands become dramatically less useful when they and their owner’s fingertips are coated in a fine layer of teflon, vocal cords or the median nerve turned into cheese at about 1.5 cubic centimeters per person would make even wandless spell-casting impossible. More destructive but non-lethal options are left as an exercise for the reader.
Ironically, non-lethal transfiguration was probably available, even if Harry wouldn’t or couldn’t think of it—there’s no restriction to, say, converting people’s blood into propofol or methohexital, for example.
Now, why didn’t you suggest this during the exam!?
On the other hand, the description in chapter 114 read a lot nicer than all the suggestions that I read in the discussion thread on chapter 113. I guess there’s a difference between the bare-bones suggestion (which is clever, but unsatisfying) and the fully fleshed out story (which I found satisfying enough) and I did not think of this in my earlier comments. My apologies to everyone who got a doubtful response from me!
But, what would “letting Harry out of the box.” mean? Letting him live, while Voldiemort still takes over the world?
Well, that’s not really a worse situation than we’ve had all through chapters 105-112, and still leaves Harry in a position to take any opportunities to stop Voldemort that appear. Being dead while Voldemort takes over the world, however, would have been quite a lot worse.
Well, it depends how long EY wanted the story to go on for. With another four chapters to wrap everything up, there’s not enough time for Voldemort keeping Harry alive while he takes over the world, before the tables turn again, Harry is sprung from a dungeon and saves the day.
They prohibited saying something too abstract, like “Harry comes up with a way to persuade Voldemort to let him out of the box.” They did not prohibit actually figuring out a way to persuade Voldemort. By extension, it would also not be allowed to say “Harry comes up with a way to kill all the Death Eaters with magic.” It just had to be specific enough.
Voldemort doesn’t want the world destroyed, and he just made Harry into a world-destruction-preventer. Pointing this out — and pointing out that Harry is now a better world-destruction-preventer than Voldemort could become — doesn’t involve changing Voldemort’s utility function.
(Voldemort can’t swear an Unbreakable Vow akin to Harry’s because nobody has trust in him that could be sacrificed to power it.)
He didn’t make Harry into a world-destruction-preventer. He only made Harry swear not to actively destroy the world. Also, while Merlin might think that with all the effort Voldemort went through to prevent Harry from destroying the world it would be easier to destroy the world with a piece of cheese, I wouldn’t find that so comforting.
He doesn’t have to be persuaded to be good, he just has to be persuaded to let Harry out of the box. If he lets Harry out of the box for non-good reasons, that still counts.
The rules stated that we couldn’t change Voldemort’s utility function or turn him good, but his utility function already placed an extremely high value on not having the world destroyed, or losing his immortality. It was quite possible that the solution would have been to convince him that killing Harry would end the world, or that he required Harry in the future in order to save it. The Vow and the parseltongue both were valuable tools in convincing Voldemort of this.
I’m surprised the Vow allowed Harry to do anything except talk to Hermione. I did worry that V would think of Harry triggering resonance by touching her. But I also thought the doom-sense would allow V to detect any spell whatsoever that Harry used.
I’m so disappointed that the Partial Transfiguration faction turned out to be correct.

Thank Merlin they didn’t listen to us and continued submitting PT solutions. :)
Shotgun plotting: sometimes one hit is all you need.
Yeah. I really hoped Eliezer would go for a pure verbal solution. Something like what I proposed, but smarter.
As opposed to? (I wasn’t keeping close track of the theories as we went forward).
Those who tried to honestly persuade or verbally trick Voldemort into letting Harry out of the box.
But, what would “letting Harry out of the box.” mean? Letting him live, while Voldiemort still takes over the world?
