Hogwarts: I'm Harry's older cousin

Chapter 341, page 335: Isn't it said that Hogwarts forbids the study of dark magic?

"One by one, you're the last one. I want to see how you're going to tear down my castle," Grindelwald said, staring at Dudley, his heterochromatic eyes seemingly trying to see right through him.

Dudley shrugged innocently; he was genuinely afraid of tearing the castle down.

After all, transmutation arrays can also be classified as magic.

"Redhead, you're the first one here."

Grindelwald casually pointed and hit Ron.

The most powerful spell

Ron, whose name was called, scratched his head in a bit of a headache. He didn't seem to be very good at offensive spells. So...

Ron pointed his wand at Grindelwald.

"Thunderous explosion!"

Strictly speaking, this is an extremely dangerous curse, one of the most destructive curses, capable of exploding anything it touches. Peter Pettigrew used this curse to blow up a street and kill 12 Muggles.

It manifests as a ball of fire that explodes.

As the spell ended, an orange fireball-shaped flame engulfed Grindelwald's body.

Ron wasn't worried at all that his spell would hurt the other party, who was Grindelwald, the legendary dark wizard who was on par with Professor Dumbledore.

"It's powerful, but it has many shortcomings. If you had raised your hand just a little bit higher, its destructive power would have increased by at least two levels."

After giving his brief assessment, Grindelwald looked at the other person: "The one with the platinum hair, you're the second one."

Draco didn't mince words. Although he wasn't an Austrian wizard, he had grown up listening to Grindelwald's stories.

"The Divine Blade is Without a Shadow!"

Aside from the three Unforgivable Curses, the Divine Edge is a fairly standard form of dark magic. It's powerful enough without violating wizarding laws. Most importantly, if you don't know how to counter it, you can't undo its effects.

An invisible wind blade pierced through Grindelwald's body, cutting a deep crack in the wall behind him, revealing the other side of the wall.

Thunder Explosion is an area-of-effect (AOE) spell, while Divine Strike Without Shadow is a single-target spell.

"That's a very interesting spell. I think I probably know the trick."

Grindelwald, who should have been pierced through the body, was unharmed. He extended a finger and flicked it, and an invisible wind blade, just like the one Draco had just cast, struck less than ten centimeters from his feet.

He mastered the secrets of the Divine Sword Without Shadow after just one viewing.

Third place.

Neville tossed a few seeds at Grindelwald.

"What is this?"

While Grindelwald was still puzzled, the seeds rapidly changed, taking root and sprouting at an incredible speed, eventually turning into mature plants.

The next second, a massive net swept towards Grindelwald.

These are devil's webs.

"!!!"

Grindelwald remained calm and pointed his finger at the demonic web as if it were a wand. No one knew what spell he used, but the demonic web immediately withered and died.

Grindelwald picked up the withered branch from the ground and examined it for a while before exclaiming in surprise, "It's not a magical summon, but a miraculous plant that has been ripened by artificial means. What a brilliant idea!"

Hearing the praise, Neville said somewhat shyly, "I'm not very good at dark magic. I made these based on Professor Sprout's ideas. Although my goal is to make magic cabbage, unfortunately, I can only make these devil webs for now."

Even a Devil's Net is already quite impressive. Imagine the opponent suddenly throwing out a Devil's Net. Even if it has weaknesses like being afraid of light or fire, it is still very useful when you are caught off guard.

Incidentally, Neville's dark magic is being compared to that of Dudley and Harry.

"If I were a professor, I would give your herbalism class an O."

Grindelwald's gaze fell on Hermione, who was the fourth to make a move.

After the first three young wizards, Grindelwald's attitude towards them changed considerably. As Dumbledore said, they were indeed outstanding. Of course, the disciplinary group also looked at Grindelwald in a different light.

As expected of the new tutor Dumbledore found, he is more capable than all the other professors at Hogwarts combined.

Hermione flicked her wrist, making the standard starting motion that even Grindelwald praised.

"Is that a Transfiguration Charm? It's quite sophisticated for your age."

Grindelwald was slightly disappointed when he first saw Hermione's spell, but then he noticed something and his eyes lit up. He said, "No, it's not just a Transfiguration Charm. There's something else in it. Oh, it's a combination spell. It's quite beautiful."

What is a combination spell? For example, Grindelwald once added a Transfiguration Charm to his Fiendfyre spell, which allowed his Fiendfyre spell to take on various forms, not only increasing the power of the spell but also enhancing its versatility.

Hermione's addition of other spells to the Transfiguration Charm is similar in principle, and in a sense, it can be considered an innovation in spells.

Just as other people's Spring Water is just an ordinary water gun, Dumbledore added a Transfiguration Charm to Spring Water and increased the flow, thus creating the Water Prison.

In terms of difficulty, it's not a case of 1+1=2 for both sides.

Grindelwald remained nonchalant, offering his critique of Hermione's magic before effortlessly deflecting it with a flick of his finger.

"You are the most outstanding witch I have ever seen at this age."

Nowadays, very few wizards study combination spells. This requires not only extremely strong talent in spells and transfiguration, but also rigorous basic training day after day. So when Hermione cast the combination spell, he already had the idea of ​​teaching her.

Grindelwald turned his gaze to Harry, the protagonist of "The Boy Who Lived," or rather, one of the two futures he saw. The first four had already given him quite a surprise, so what would the fifth bring him?

Harry looked intently at Grindelwald, his palms slightly sweaty as he gripped his wand. Dudley had told him before he came that he must show his best.

My strongest magic?

So

"Fiendfyre!"

The tip of the wand shattered, and black flames instantly filled the entire room. Just as Grindelwald was about to intervene, the black flames quickly condensed into several fireballs, which floated around Harry.

"Fierce Fire?!"

He was a master of Fiendfire himself, and was extremely familiar with the Fiendfire spell. He was not mistaken; it really was Fiendfire, without a doubt.

Releasing Fiendfire isn't difficult; many wizards can do it. The challenge lies in controlling it; if you don't control it properly, you'll turn yourself into charred remains.

This "savior" is truly skilled at controlling the notoriously unstable Fiendfire within a certain range.

But a new question arose in Grindelwald's mind at that moment.

Isn't it said that Hogwarts forbids the study of dark magic?
