Professor Malfoy was naturally not so idle, and casually went to pry open the student's Heavenly Spirit Cover to see what bulls, ghosts, snakes, and gods were inside.

- After all, it is so convenient for the Dementor to take the mind, and it is too bloody to pry open the Heavenly Spirit Cover or something, which is not in line with the behavior of a pure-blood wizard.

After filling the shelves, he took two steps back, looking at the wall decoration made of fragments of various magical creatures with appreciation, and his heart was satisfied.

Black magic should have the appearance of black magic, and it's not too much to decorate the classroom with hearts, brains, eyeballs, or something, right?

"However, over the years, many biological tissues with strange magical powers have been inactivated, and now they can only be used as decorations."

I have to say that this is a big pity.

Fifty years have passed, and with the exception of some specially preserved things and a few objects with strange powers in their own right, many of the good things he has painstakingly collected have become worthless and have to be cleaned up.

"After all, the space in which the Traceless Stretching Spell unfolds does not have the effect of preserving freshness, and the attack by Grindelwald back then was too sudden, and many plans were forced to fall into a deep sleep before they were completed, avoiding the impact of the Death Curse."

Professor Malfoy turned to look at the Dark Magic Professor's work, and saw that more than half of the students had managed to blow up their armor with their wands.

He took out his dark gold pocket watch and looked at the time, there were still twenty minutes before the end of class.

"Twenty minutes...... Well, ladies, gentlemen. ”

The slight light on the wand in his hand flickered slightly, and Professor Malfoy's voice overshadowed the still deafening explosion.

He still sighed in his heart that the sound insulation of the castle was really good, and the explosion was in full swing here, so far no other professors had come to talk to him about life.

Professor Malfoy's voice was so recognizable that several young wizards had just tried a spell and swallowed the sound they were about to blurt out.

They looked over, and a few lines of words automatically appeared on the blackboard behind Professor Malfoy.

Confringo.

Spell Weight: 4.

Hazard classification: relatively safe.

Subordinates: Attack Spells\Demolition Spells.

Legal Restrictions: Not for use in the Muggle world.

The third-year students, even if they shattered their armor, did not leave rashly.

Professor Malfoy was pleased with this, though he knew it was because of the meditation basin from the previous lesson, and the morning incident that had spread silently.

But it doesn't matter...... Professor Malfoy smiled, he had come to Durmstrang for one purpose, teaching was only incidental.

Whether the students like him or not has no effect on him, in his eyes, as long as he doesn't make trouble, he is a good child.

Well, as long as you don't mess with it, everyone is a good boy.

"I'm sure you've already noticed that the explosion spell you used couldn't completely destroy the armor at first...... Mr. Cotton. ”

Professor Malfoy stared at the students in front of him, not explaining what was written behind him.

Cotton was agitated and hurriedly squeezed away several students in front of him.

"Professor!"

"Now please tell me what are the specific precautions for the Confringo."

"Yes, yes." Cotton hurriedly recalled, word by word:

"The essence of the explosion spell lies in the specific object it points to, and generally speaking, the explosion spell can only shatter those things that have no magical limitations and are relatively weak inside, but this varies from wizard to wizard."

"Again, the direction of the spell is very important, well-"

Speaking of this, he was suddenly a little surprised, and the eyes of the classmates around him made him nervously forget his words.

"Where the spell hit." Professor Malfoy added, "The explosion is the most powerful where the explosion hits, and the location of the explosion is crucial in order to deal damage more effectively. ”

The explosion spell performed under the same conditions, one to the head and the other to the leg, these are completely different endings.

"Yes, yes!" Cotton immediately agreed.

"Please continue." Professor Malfoy bowed.

"Oh, good, good." He tried his best to ignore the gazes of those around him, as if he were an endorsement:

"The second is the chanting of the spell, the amplitude of the wand swing, and the mental state of the caster, which may cause the difference in the power of the spell. We should be careful when we wave our wands......"

Standard textbook statement.

Professor Malfoy nodded, signaling to Mr. Cotton to be already.

"Generally speaking, the magical power of the spell itself will vary from one wizard to another."

"The spell, the wand, the psychological factors of the spellcaster, including the object of the spell's hit, are among the reasons that affect the power of the spell."

"The armor in front of you regenerates itself, using the Explosive Spell to hit the target...... Mr. Brassau. ”

This is the first little wizard to attack armor.

Brasso squirmed slightly, and felt unnatural under Professor Malfoy's gaze: "That, that ......"

"yes, I mean, I've been trying to attack the helmet, but I can't blow it up......"

Obviously, the repair charm engraved on the armor is not on the helmet, and the spell is not powerful enough, so it is normal that it cannot be blown clean.

"Thank you very much Mr. Brasso for your valuable advice."

Professor Malfoy didn't comment, but instead called out the little wizards who didn't blow up the right place one by one, and let them eliminate the wrong options themselves.

Mass-produced repair spells are all engraved in one place, and the location is relatively hidden, but as long as they blow up the right place, they can completely shatter it at the level of their spells.

And it was clear that Professor Malfoy, who had been struggling with what to put on the shelf, had been paying attention to them.

- I'm afraid that one of them will accidentally blow himself up and increase his workload.

"To sum up, I believe you have a full understanding of how to choose the direction of attack...... Well, there are ten minutes left and there is no continuation of the next time to blow up the armor, then we will add a very important concept now. ”

"I'm sure you've seen what's written on the blackboard."

Professor Malfoy leaned over and looked at the lines of words written behind him.

"The danger classification of the spell, the subordinate and the corresponding legal restrictions, I think the ladies and gentlemen should be able to understand."

"So who can tell me what is the weight of a spell that is a fairly important indicator in Charms?"

The classroom was silent, and Craig wrinkled his eyebrows and whispered to Colin, who read the most books among them, "What is the weight of the spell?" ”

Colin was also at a loss, his knowledge was limited, and the weight of spells obviously belonged to advanced spell knowledge, which he didn't know.

Victor on the side explained in a low voice:

"An authoritative indicator that comprehensively considers the danger of the spell, the conditions under which it is used, the impact it will have, etc., to distinguish the level of the spell."

"To put it simply, it's how easy it is to learn spells. The higher the weight, the fewer people will use it, the more powerful it will be, and the greater the damage and impact it will cause. ”

Although the weight of spells is not touched upon in the knowledge that young wizards are exposed to, most adult wizards have not even heard of the name.

However, in authoritative spell books, the weight of spells is used as a standard to measure the power of spells, so it is very specialized, and it is an indicator academic term that is not seen in daily life, but often appears in academic discussions.
