"Professor, how do you judge your best spell?" a Slytherin student asked.

Snape said coldly, "Those you learn the fastest and use the best. Other than that--"

"If you can invent a spell yourself, it is naturally your best spell." After that, he swung his robes and strode off the stage.

Offstage, Ron and Hermione looked at Harry at the same time, and the meaning of their eyes was different:

Hermione: So your best spell is the Disarming Charm?

Ron: That's it? It must be an advanced spell, right?

When Felix stood on the stage, the young wizards were still immersed in the atmosphere created by Snape. Although he did not talk about any specific magic, it was still moving.

Felix decided to show some practical knowledge.

"At the end of the last class, we mentioned a point: even if it is the same spell, the effect released by different wizards may be very different."

"This situation is particularly obvious in duels. After all, it is hard to imagine that a wizard would spend a lot of time and energy studying the spell of 'clean up'."

"Most daily magic is the same. We will not use them to explore the mysteries of magic or beat the opponent to the ground." Felix made a joke.

The little wizards in the audience laughed softly.

"For wizards who are good at dueling, they have amazing attainments in one or several magics."

He glanced at the wizards in the audience: "Take the Disarming Spell as an example-"

Felix waved his wand, and a slender red light flashed.

"This is the initial level of mastery."

Harry watched carefully, this is exactly the level he can release now.

Many little wizards who have mastered the Disarming Spell did the same thing. And the result of the comparison is that most people are at this level.

"——This stage is the beginner level, and there is a possibility of failure in casting spells." At this point, Felix said with a little distress: "For the sake of understanding and comparison, let's call it a first-level spell."

"At this time, the factors that affect the success rate of spell casting are your casting movements, chanting, confidence, magic mobilization and other basic contents. I won't expand on it. There is a detailed description in the materials of the last class."

"And when you practice more times, practice makes perfect, and there is almost no chance of failure in casting, just like this-"

Felix waved his wand, and a clear red light flashed across the top of the auditorium.

Harry heard the excited voice of his senior, Albert Balk, who had just been called up to demonstrate, saying: "This is my spell!"

"For the sake of understanding, we can call it a second-level spell."

Felix leisurely drew arcs with his wand, as if he was conducting a symphony.

"On this basis, you have invested more time and energy in studying spells - preferably with the guidance of a teacher, and its power will be appropriately enhanced."

Felix waved his wand, and a red beam of light as thick as a finger shot out, spanning half of the auditorium in an instant.

"This is a third-level disarming spell... By analogy, it is somewhat like the threshold of professionalization in the wizarding world, such as the novice doctors and new Aurors of St. Mungo's who have just undergone training."

The young wizards all stared at Professor Hepp, listening carefully to every word he said. They intuitively thought that today's class was very important.

Even the expressions of several professors became serious. Snape was curious about what level Felix would push the spell to?

Spell grading, huh, that's something he would do!

Felix on the stage continued to speak slowly, "Next, your understanding of spells will become deeper and more proficient. You can even make some changes to the spells themselves to suit your personal habits--"

A beam of light flew out from the tip of the wand, but this time the spell was more condensed, and the color was mixed with white light, and it left a clear arc in the air.

"The power is not much different from the third-level spell, but it is more controllable and wins with subtleties. It can be called a fourth-level spell." Felix said, "In addition, this is also the level of spells that those talented Aurors and St. Mungo's doctors are best at after working for a few years."

Felix nodded slightly. From here on, not everyone can do it. Talent, perseverance, and teaching are all indispensable.

Harry looked at Professor Hep on the stage. He felt that he couldn't breathe. After a long while, he realized that the emotion that just surged into his heart was desire.

After a long pause, the little wizard looked at Professor Hep eagerly.

Anything else? Can we continue?

Level 5 spell? Level 6? Level 7, 8, or 9? I'm really curious!

Professor Hepp lived up to everyone's expectations. He continued, "Above that, if you are a senior Auror who has spent almost half of your life dealing with various dark wizards, then the spell you are best at is probably like this—"

The scene seemed to be reproduced yesterday. A spell as thick as a wrist shot out, spanning most of the auditorium and hitting the wall of the castle directly.

The red arc of magic light like thunder continued to twist and extend.

Until Felix retracted his wand, the red light that illuminated half of the auditorium finally disappeared.

"This may be called a level 5 spell."

The young wizards in the audience watched this scene speechlessly. Even if they saw it for the second time, they were still shocked.

Felix thought, it was like Lockhart's "Oblivion". But it can't be compared like this, because Lockhart was lucky to have received the gift of ancient magic.

Ancient magic is naturally powerful, but there is no point in discussing its power, because you don't know if the next time you use

it, it will suddenly go out of control due to lack of control. The young wizards in the audience were quiet, like a group of quails swept by a strong wind. Looking at their expressions, it seemed that someone had just knocked open their heads and stuffed a bunch of messy things into them, making them completely unable to think.

After more than ten seconds, Felix clapped his hands and said, "Of course, the above spell levels are just for your convenience. In reality, there is no such division as first-level and second-level spells."

"Magic is unconstrained, and it makes no sense to divide many magical spells into levels."

"Also, I must remind you that even in a duel, it is not the best choice to only pursue the power of spells. If you want to become an Auror, you need to master many things, which are equally important."

"Next--"

But these words did not work. The auditorium seemed to explode. The young wizards raised their hands enthusiastically. It can be seen that they have a lot of questions.

"Professor, what is a sixth-level spell like?" Finally, someone in the audience couldn't help but shout out.
