Streams of green and red light shot across the ground close to the foot of the castle.
Shattered stones.
Broken wooden clubs.
It was clear that the tactic of using stone soldiers as support while the professors led the main assault had indeed caused the enemy no small amount of trouble at first, even showing signs of pushing the front line back.
But once the elite Death Eaters led by Barty Crouch Jr. entered the battlefield, the balance of the battle quickly began to shift.
Although most of Minerva McGonagall's attention was focused on how to deal with Bellatrix before her, she still had a very clear grasp of the current situation on the battlefield.
If reinforcements did not arrive soon, she, the other professors, and the stone soldiers would not be able to hold out much longer.
"Hmph, hmph. Is your heart wavering, Minerva?"
"..."
"By now, you should understand. With your strength, you cannot stop the Great Master's plan!"
Looking at the witch before her, who went mad at the mere mention of Voldemort, Minerva McGonagall tightened her grip on her wand, breathing heavily.
Especially when she saw the Werewolves and Giants on the verge of rushing into the castle, her heart grew even heavier.
Just as the other side had said.
If this continued, not only would they fail to stop the enemy, but they might even have to sacrifice the lives of the professors here.
I wonder if Albus has managed to lead the students safely out of Hogwarts.
"You dare lose focus while fighting me? Then die! Avada Kedavra!"
In Minerva McGonagall's widened pupils, a ghastly green light reached her in an instant.
She could not dodge it.
In a battle between powerful opponents, even a single second of distraction could decide life and death.
And Minerva McGonagall, the Deputy Headmistress of Hogwarts, seemed about to deliver her final lesson here.
...
Avada Kedavra.
Also known as the Killing Curse, the Death Curse, or the Life-Taking Curse.
It was a powerful dark magic known as one of the three Unforgivable Curses.
When cast, it fired a green beam of light from the wand, instantly killing any target it struck. It was one of the dark magics most commonly used by murderous dark wizards such as Voldemort.
Although most wizards needed to shout the Killing Curse aloud with murderous intent when casting it, a very small number of exceptionally powerful wizards, such as Voldemort, could cast Avada Kedavra silently, making this dark magic even more hidden and dangerous.
It was worth noting that because the casting gesture involved drawing a lightning shape downward from above, this was why the scar on Harry Potter's forehead was shaped like lightning.
In any case, the Killing Curse Minerva McGonagall now faced was an extremely powerful dark magic, because it could not be blocked by the vast majority of ordinary Charms.
In other words, it could still be blocked.
Just as the Killing Curse was about to strike Minerva McGonagall, an urgent shout rang beside her ear.
"Wingardium Leviosa!"
No one was unfamiliar with this Charm.
It was the first basic Charm every young wizard learned after entering school.
And it was this unbelievably simple Charm that blocked the Killing Curse, a curse that terrified anyone who heard its name.
Boom!
A flying stone collided with the incoming green light.
Although the Killing Curse shattered the stone, it also lost its forward trajectory.
That was right.
Aside from dodging, the simplest way to block an attack from the Killing Curse was not magic.
It was physical defense.
