It's debatable. For once, Levicorpus was a popular nonverbal spell at the time, and I don't see Snape as the sharing type - if it's silently cast, how come everyone knew it? And while Levicorpus is written in the book after many crossed out versions (maybe Snape tried to replicate it?), Sectumsempra is scrawled there without any prior notes, and Harry thinks that the Prince simply copied the curse into the book. Snape claims he invented them, but that doesn't really comply well with the evidence.

 

Ha! Fuck Snape.

I'll reread the books, but the claim was something like "Using my own spells against me, Potter?" during the impromptu duel after the breach of Hogwarts in book 6, right? Or is there more about it?

 

He straight up claims he invented them, and IIRC Lupin says Sectumsempra was his signature curse in DH. Still, the discrepancies keep the question open.

 

Okay then, Thanks Atram Noctem. My headcanon: Fuck Snape, he was a petty braggart.

 

There's also the question of how James would have used Levicorpus on Snape in his memory from OotP, if he had invented it and it was nonverbal, unless the Marauders had gotten hold of the book at some point.

I've heard it said that the spell used to cut James' cheek may have been Sectumsempra, as well, and it would be interesting to compare that to Harry's use of it in sixth year, and for the first time at that, to utterly devastate Malfoy.

 

Just re reading DH.

Saying Voldemorts name not only alerts people but it causes protective charms to collapse. That's how they catch Harry.

So if your in prison, in, lets say Makfoy manor. Why not just say his name and cause the spells to break and apperate out.

In fact it seems a great way to catch Death Eaters or Snatchers. Get a dozen friendlies, sat the name and ambush who ever comes. A little imperio a bit or truth serum. You could destabilise the regime in a matter of days.

 

The magical world and logic just don't mix I guess. However I think part of the problem is that people expected Voldemort to show up when they said his name and people knew that they couldn't fight Voldemort and win.
I also think that the wards at the manor wouldn't have fallen simply because they had a Death Eater spell mixed within the ward scheme if you recall the gates would open for the dark mark. So I think what you might actually get is the Malfoy's alerted to your presence in their house and no freedom.

 

I don't think the anti-disapparation spell counts as a protective spell.

 

Ron couldn't apperate back to the camp when he left. Yet the snatchers could once the spells collapsed.

Which brings the point, why didn't the trio pop away when the heard the snatchers arrive?

 

IIRC, they tried and couldn't, but I could be mistaking. Considering the purpose of the Taboo, it would be logical if it prevented to apparate out of the location, but not in.

 

The trio didn't have any protections preventing apparition. Ron did try to apparate back:

Also, he caught with Harry and Hermione towards the end, but he still couldn't find them thanks to their protective enchantments:

Furthermore, the taboo didn't break the Fidelius at Grimmauld place nor the anti-apparation spell at Hogwarts. Safe to say that the taboo does nothing to anti-disapparation spells.

 

Wow, that bit about him escaping makes Ron seem like much more of a badass.

 

The only thing I can say is that Harry and Hermione didn't really go to see Bathilda herself, Nagini went to them when they were in front of the Potters house. So I think she was just waiting for him to visit his old house.

As to why not leave Nagini in the house itself instead, I'm not sure. Maybe he thought Harry would have expected a trap in the house and so would be harder to surprise?

 

Nagini's task was to alert Voldemort if Harry came to Godric's Hallow and keep him there until Voldemort came. However, Voldemort knew that a snake, no matter how powerful, would not be able to keep a wizard by force for a long time, especially if the wizard would likely have companions. Even if Nagini could attack and injure Harry, there was always a chance Harry could apparate and escape. And Nagini killing Harry was not an option, since Voldemort believed he must do it himself during the DH.

So, it would be highly likely that Nagini would not be able to hold Harry by force. A better plan, then, would be to divert Harry's attention until Voldemort could arrive. But to do so, Nagini would have to disguise as someone who 1) was significant enough to hold Harry’s attention in the first place and 2) did not pose a danger to him (which would make him run away). The best solution would be Bathilda Bagshot, who was a renown historian who also happened to be known as Dumbledore’s family friend.

 

Yes. From DH:

 

Is there ever a mention of what Dumbledore's original wand is made of? (The one before he wins the elder wand)

 

No it was never mentioned.
