Also the thing with multiple wands doesn't seem fully explored

Maybe there are potential drawbacks

There's also the logistics of multiple wands and how could that be optimised,

would packing multiple cores into one wand achieve the same effect, or would it damage the wand ?

And I assume more wizards haven't tried to wand thing due to arrogance and being stuck in the past

Duck-foot pistol, but it's just a lollipop stand loaded with Ollivander's factory seconds. It'd almost look like a toy broom until it sweeps an entire squad.

Whatever you say is Latin for "fuck everyone in this general direction."

I'll just use my bundle of sticks, my wand strap to Wingardium Leviosa you straight into the sun.

I wish he did this. This is Gold!

In the books, wands aren't just objects. They have a degree of sentience and therefore can conceivably rebel against the user. I imagined there is a compatibility issue with using multiple wands at once that may have been temporarily suspended when Harry used them on Fenrir. Might be cause the wands hated Fenrir too or liked Harry enough to let that one spell go. I don't know. But in my own head canon the use of multiple wands is untenable because it just doesn't work out and the wizard is more likely to explode themselves that fire off a good powerful spell and Harry, as always, just has really good fucking luck.

Is this in the books or the movies

Wands don't generate mana / magical energy. Wizards do. The wands are just efficient at chanelling it in a single beam. So if you use multiple wands together, you sacrifice staying power for firepower. Which means if you miss, you'll take longer to recharge, and meanwhile you are a sitting duck.

In one of the Fantastical Beasts movies there is mention of atomic bombs in some visions and they see it as a major threat. So it's kinda canon that some non-muggles know about nukes.

When Harry meets Hermoine he tells her to name all the quarks or else she's an NPC.

Which is intense whiplash from the previous chapter, where politely asking Draco to describe the Death Eaters' whole deal has him ticking off rhetorical beats for plain old fascism.

Basically, the Less Wrong guy wrote a full Harry Potter novel, and it is exactly what you'd expect. Some aspects are fantastic! Others... yikes.

A detail I love that's not a spoiler: Crabbe and Goyle are well-characterized to act exactly the way they are in canon. They've been molded as bodyguards since they were little, and now they're in wizard middle school getting to play tough-guy bruisers on Draco's behalf, so of course they're tryhard doofuses that he finds mildly embarrassing. But when Quirrel invites one of them to spar, demonstrating the ancient mystical defense known as... judo... Goyle quietly asks what belt he has. Quirrel says "seventh dan." The tough-guy act comes right back up, and Goyle throws himself into it, because he knows he's about to get his ass kicked, safely.

The whole thing is ultimately about modeling people on these layers of facade. A lot of it gets overly analytical and kinda up-its-own-ass. Certain characters call that out and condemn actions at face value, so some of it's deliberate writing for the protagonist and antagonist. But only some.

Even with abundant benefit of the doubt, figuring 'this guy wrote Harry like a know-it-all child,' any recommendation would be complicated.

Dammit, I really need to read the rest of Wildbow. I only read Worm. Is the one after Worm any good, or are the other series better?

I have so much to reeaad...

Thanks! Good bot.
