"Professor, how can I judge which spell I am most comfortable with?" A Slytherin student asked. Snape said coldly: "Those you learn the fastest and use the most. Other than that--"

"If you can invent a spell of your own, it is naturally your best." After saying that, he flung his robe and strutted off the stage.

Offstage, Ron and Hermione looked at Harry at the same time, and the meaning of their eyes varied from each other.

Hermione: So you are good at disarming charm?

Ron: That's it? How can it be compared to advanced magic spells, right?

When Felix took 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 stirring.

Felix decided to pull out a little dry stuff.

"At the end of our last lesson, we brought up the point that the effects of the spell, even if it's the same spell, the effects released by different wizards can differ widely."

"This is especially true in dueling; after all, you can hardly imagine A wizard spending a lot of time and effort researching the spell 'Scouring Charm'."

"The same is true for most life magics. We don't go through them to explore the mysteries of magic, or to beat the crap out of our opponents." Felix made a joke.

The young wizard on the stage laughed lowly.

"For wizards who are good at dueling, they have amazing attainments in one, or a few, spells."

He swept his gaze around the stage at the wizards, "Take the Disarming Charm as an example-"

Felix waved his wand, and a slim red aura flickered away.

"This is the initial level of mastery."

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

Many of the young wizards who had mastered the disarming charm carried the same action. And the result of the comparison is that most of them are at this level.

"-This stage is at the novice level, and there is a possibility of failure in casting spells." Speaking of this, Felix said with a slight bitterness, "For the sake of understanding and comparison, let's call it a level one spell."

"At this juncture, the factors that affect the success rate of spell casting are your spell casting motion, chanting, confidence, magic power utilization, and other such basic elements. I won't expand on that, it's described in detail in the materials from the last class."

"And when you practice more often, practice makes perfect, and there is almost no failure of release, just like this-"

Felix waved his wand and a distinct red light streaked across the top of the great hall.

Harry heard the excited voice of his senior, Abbott Blake, who had just been called up for the demonstration, saying, "That's how my spell works!"

"For the convenience of comprehension, we may call it a Level Two spell."

Felix leisurely drew an arc with his wand, as if he is conducting a symphony.

" You invested more time and effort to delve into this spell - preferably with the guidance of a professor, and its power will be appropriately enhanced."

Felix waved his wand, and a finger-thick red beam shot out, spanning half of the great hall in an instant. Sᴇaʀch* Thᴇ N0ᴠᴇFɪre.nᴇt website on Gøøglᴇ to access chapters of nøvels early and in the highest quality.

"This is a level three disarming charm ... in the horizontal classification, somewhat like the threshold of professionalization in the wizarding world, such as a novice St. Mungo's healer who has just undergone training, a newcomer Auror."

The young wizards were all staring at Professor Hap at this point with unblinking eyes, listening carefully to every word he said. They intuitively thought that this lesson would be very important today.

Even the expressions of other professors were serious, and Snape wondered how many levels Felix would push the spell to.

Magic spell levelling, heh, is something he would do!

And Felix on the stage still unhurriedly narrated, "Next, the deeper understanding you have of the spell, the more comfortable you are with it, you can even make some changes to the spell itself to suit your personal habits--"

A beam of light flew out from the tip of the wand, only, this time, the charm is more cohesive, the colour is also mixed with white light, it is even left a clear arc in midair.

"The power is not much different from the third level magic spell, but the controllability is higher, and it wins with subtlety, so it can be called a fourth level spell." Felix spoke, "One more remark, this is also the level of that talented Auror and St. Mungo healers, after working for a few years on their best spells."

Felix nodded slightly, and from here on out, it wasn't for everyone. Talent, perseverance, and teaching, you can't have one without the other.

Harry looked at Professor Hap on the stage, he felt like he couldn't breathe, and it took a few moments before he realized that the emotion he had just felt welling up in his heart was longing.

After a long pause, the young wizard looked at Professor Hap dimly.

Is there more? Can we continue?

A Level Five spell? Level six? Seven, eight, ninth level? I'm really curious!

And Professor Hap lived up to the expectations as he continued, "On top of that, if you were an experienced Auror and had spent almost half your life dealing with various dark wizards, then your best spell would probably be something like this-"

The scene was like yesterday all over again, a wrist-thick magic spell shot out, spanning half of the great hall and hitting the castle wall straight on.

The red thunder-like arc of magic kept twisting and stretching.

Until Felix withdrew his wand, the red light that reflected half of the great hall finally disappeared.

"This might be called a level five magic spells."

The young wizards offstage looked at the scene wordlessly, even though it was the second time they saw it, it was still shocking.

Felix pondered that it's like Lockhart's 'Forgetfulness Charm'. But again, the comparison could not be made in this way, because Lockhart was lucky to have been blessed with ancient magic knowledge.

Ancient magic is naturally powerful, but there is no point in discussing the power because you don't know if the next time you use it, whether it will suddenly get out of control due to lack of control.

The young wizards on the stage were quiet and peaceful, like a flock of Quails swept by a gale. Looking at their expressions, it seemed that someone had just cracked open their heads and stuffed a bunch of messy things inside, making them completely unable to think.

After ten seconds or so, Felix clapped his hands, "Of course, the above magic spell levels are only for your convenience of comprehension; in reality, there is no such division as level one or level two spells."

"Magic is unconstrained, and there is no point in dividing much of the magic that is described as miraculous by hierarchy."

"Moreover, I must remind you that even in a duel, the one-sided pursuit of magic spell power is not the best choice; if you want to become an Auror, you need to master many things, which are equally important."

"Next-"

But the words didn't kick in, the great hall seemed to explode as the young wizards raised their hands enthusiastically, and it's obvious that they had many questions.

"Professor, how does a level six magic spell look like?" Finally, someone offstage couldn't help but exclaim.
