Crossover Muggles in Harry Potter

[Midnighter13]

That just shows how stupidly powerful and easy to use it is. As for the spell burning out, actually it was contained in the RoR, note sure what the word of god was on that, but I am pretty sure the room was destroyed. That is why Hogwarts didn't go up in flames. Just imagine a bunch of 'Goyles' teleport in with portkeys to their assigned cities, cast the spell, and then say the word to port key the heck out of there. Even if it is 1-4 blocks that are consumed, that would still be on a similar level of devastation to 9/11. Heck wizards could fly disillusioned around the city on brooms casting the spell and then portkey out when they are in danger.

See, now we've gone from a single wizard being able to burn an entire city in seconds, to 4 wizards being able to burn a few blocks per strike. That's a huge downgrade. If that's what they are using, the muggle world is vast enough that they could tank those sorts of attacks until they are able to recruit enough muggleborn to raise anti-apparition wards and stop them. Even the equivalent of a 9/11 per day for a year or two wouldn't be enough to destroy the muggle world. The Blitz wasn't able to stop Britain after all. There is a reason Voldemort couldn't just Fiendfrye all of Hogwarts in book 7. Its not the all powerful nuclear option you seem to think it is.

Magical fire that chases down the living, is immune to water, and can burn stone is not something that muggle techniques can fight.

As for city killers, Grimdelwald was casting a spell that would have burnt Paris to ash and killed everyone in the city save those who were loyal to him.

My example was the bare minimum in regards to AOE from what we have seen. In addition The Blitz gave warnings and people were evacuated or took shelter. This is not comparable to a multi-city attack, all times of the day, no warning, no defense. It would be more accurate to compare a small group of wizards attacking as ~100 9/11s every single day. There is no way any government or populace can hold up under such an attack.

The reason Voldemort doesn't want to use Fiendfyre on Hogwarts is that he views it as his home to some extent and it is a symbol and place of power of the magical world. He also seems to prefer killing people in person. It should be noted that the fire based attack he used against Dumbledore bares similarities to Fiendfyre, showing he is not averse to using such a spell if necessary.
