I’m curious now...
We know that Obliviation doesn’t erase everything—it erases memories but not every effect of the experience it erases. We’ve even seen it in story—Rianne Felthorne felt sad when looking at her “found” ruby. McGonnagall also hypothesized that Harry might have been abused(or otherwise experienced something awful) and then Obliviated.
Either way, I’m curious how this effect would interact with something like this.
If Harry told you the secret of the True Patronus(and you weren’t the sort of person who could kill Dementors with that knowledge) and you Obliviated yourself, would that be enough to restore the capacity to use an animal Patronus?
Ch 78 You know, of all the things in the chapter, the law of Potion-Making seems the most important, by far—if I understand it correctly, it has staggering implications.
It’s clear that you can extract more than purely physical processes from ingredients—since we have potions that bestow even entirely abstract concepts like luck(and canon!Snape claimed to be capable of brewing fame and glory, I’m unsure if MoR!Snape claimed the same).
So, could you, say, take a CD with some software on it and use it as a Potions ingredient in order to extract the mental work that went into programming that software, creating a Potion of Excellent Programming or something? Or, even better—could you take a copy of some brilliant scientific research paper, extract the brilliant scientific genius out of it and use the resulting Potion in order to create an even more brilliant scientific breakthrough? That’s godhood in one shot right there.
I also have to wonder how Potion-Making interacts with the Mind Projection Fallacy. If you use a video game as an ingredient, can you create a Potion of Fun out of the video game or no? Fun isn’t an inherent property of video games, it’s in the minds of the players.
