The Rune Mage Starting at Hogwarts

Rizz first found an old third-grade textbook in the locker, and then turned to the section for shrinking potions.

He didn't have Harry Potter's magic potions book; instead, he had a notebook filled with them.

This old textbook is very clean; there are no notes on it.

Ritz first dutifully took out the corresponding materials according to the book, and then sat down in his favorite seat to read the book carefully.

After studying it for about fifteen minutes, he memorized all the details of the shrinking potion and even performed a simple arithmetic calculation on it.

During this time, he also asked Ellie to go back to her room to fetch his potion-making tools and notes.

Snape paid no attention to Ryze's attempt to calculate the potion formula.

Although potions are indeed a type of magic, there are corresponding theoretical formulas in arithmetic divination.

However, at Rizz's current level, he can only verify the part of the theory that applies magic to potions; it does not help with the processing of materials or the temperature of the brewing process.

Sure enough, after Ritz verified the formula, he was a bit flustered when he first tried to process caterpillar slices and mouse spleens because he was not familiar with them. He also wasted a lot of juice when squeezing out the leech juice.

Needless to say, the potion-making process was even worse. Basically, less than ten minutes after Ryze first poured magic into it, the color of the potion in the crucible had already begun to change to a toxic orange-yellow.

Seeing that the potion had clearly failed, Ryze didn't waste the remaining materials that hadn't been thrown into the crucible. Instead, he quickly tidied up the crucible and began to review his failure.

After a more detailed review, Ritz handled the materials more gently and carefully this time. Although the final material was not in the best condition, at least the mistakes from the previous time were not repeated.

This time, Ritz followed the instructions in the book exactly, persisting until the first heat change half an hour later, and then inexplicably the cooking failed.

As the potion in the crucible turned orange-yellow again, Ryze looked at the materials placed to the side and rubbed his head.

The magic treatment was fine; the materials were processed only moderately but are usable; and the temperature control process was followed exactly as described in the book...

Ryze meticulously reviewed all his actions and found no obvious problems, yet he still failed.

"Something must be wrong, but the textbook doesn't mention it."

Rizzi pondered this as he dealt with the failed medicine.

At that moment, Snape also came out of his office.

He glanced at the failed potion without offering any warning.

"Don't expect anyone to bring you food; if you're hungry, go to the auditorium yourself."

He locked the office door and then warned Raz: "If I find out you sneaking into my office, I'll pour your failed potion on your head."

Having said that, Snape waved his bat-wing-like cloak and quickly left the Potions classroom.

After watching the old bat leave, and finding no results from his recap, Rizz took out Ravenclaw's ring from his pocket and put it on. Then he walked to the podium in the Potions classroom and reached out to touch the old crucible that Snape usually used.

"Since I failed to make it according to the textbook, I'll just come and see how you made it."

After all, Snape had said that it didn't matter who he asked for help from, as long as they saw the final result.

So, it seems there shouldn't be any problem for him to use Snape's crucible as a medium for divination.

Chapter 63: The Giant in the Underground Passage

After receiving Ravenclaw's gift, although she couldn't find any other people with a talent for divination to compare herself to, Rizz felt that her divination skills had improved rapidly over the past two months.

Two months ago, he needed the help of the Extrasensory Charm to barely complete a proper divination.

With the buffs he now has, he has successfully completed the initial steps of divination and no longer needs to use up all his mana in a single divination session.

Although he couldn't perceive future omens like Grindelwald, he was still much better than Professor Terry Laurie, whose divination talent was completely uncontrollable.

With a medium, and without the medium being imbued with magic, he can already use these mediums to rewind or predict events with relatively high accuracy. Of course, the longer the rewind and prediction takes, the greater the consumption will be.

However, all he needs to do now is go back to the time when Snape personally brewed the shrinking potion.

Coincidentally, the third-year students had already taken this course two weeks ago.

He didn't expend too much energy before the image of Snape brewing potions appeared before his eyes.

Even the messy handwriting behind the opponent quickly became clear thanks to Ryze's 200+ spell power and extra mana consumption.

Ryze jotted down these points of knowledge as quickly as possible, and then quickly read through Snape's entire cooking process.

"Phew..." Ryze took a breath and then wiped his forehead.

It took 10 minutes and nearly 80 mana points.

A normal divination session would only cost around 2 to 30 points of mana.

However, since Ryze needed to record the details of the other party's potion-making process more clearly, it would naturally take more effort.

Wearing dragon-skin gloves, Ryze had Ariel take Hagrid's pumpkin cake from his pocket and feed him a bite.

At this moment, he really needs something sweet to help him recover quickly.

"As expected, Snape's methods and cooking process differed slightly from the textbook instructions."

After quickly finishing the pumpkin cake, Ryze continued to look at the notes he had taken.

Snape did not change the recipe or cooking process in the textbook; he simply added some more specific steps to improve the success rate of the cooking process in details not mentioned in the textbook.

For example, the book only gives approximate amounts of leech juice and caterpillar slices, while Snape controls the amounts much more precisely.

In addition, some materials also require additional stirring after being placed in the crucible, and there are clear standards for the requirements of temperature changes.

This is typical of Snape's style; as long as you follow his and the textbook's steps exactly when brewing potions, the success rate is over 90%.

Although he doesn't explain the reasons for adding these steps, students just need to remember them and follow them.

"With these notes, making a regular shrinking potion shouldn't be a problem."

Rizz carefully reviewed the notes, confirming all the details, and then prepared to reprocess the materials according to Snape's methods.

Of course, he also remembered to ask Ellie to go to the auditorium and get him some food, and to tell his roommates about his situation, and to tell them not to worry about him if anything happened at the banquet, and to just go back to their dorm.

Rizz knew that Quirrell would bring out the trolls to disrupt the Halloween dinner.

However, he has not felt any sense of crisis from his divination talent so far.

After all, although trolls are XXXX-level magical creatures, they are indeed incredibly stupid. Apart from their large size and high magic resistance, they are useless. Some of them are even tamed by wizards to serve as guards.

Basically, students in fourth grade and above who take the Defense Against the Dark Arts class seriously can easily deal with trolls.

However, Hogwarts still has many more young wizards, and in order to prevent these young wizards from being harmed and to confirm whether it is a dark wizard invading Hogwarts, it is necessary for all students to return to their dormitories.

In the original story, all three of the little ones could use the Levitation Charm to stun the trolls. Ryze, who knew the trolls' habits better, also had Aery's protection and Arcane Comet, and had completed most of the Ultimate Flash spell, so he naturally had no need to worry about the trolls.

Rather than wasting a whole night eating fries and fish and chips in the auditorium only to be sent back to his dorm by the professors halfway through, he decided to stay in the Potions classroom and brew the normal shrinking potion first.

After Ariel returned with several smoked meat sandwiches and some fries, Ryze closed the door to the Potions classroom and then began to concentrate on processing the materials.

After preparing it, he followed Snape's method exactly, lighting the fire and adding the ingredients, then turning the fire down to a low flame for the first time half an hour later.

This time, there was no failure.

He steadily poured magic into the potion in the crucible, and then added the ingredients a second time according to the notes.

It was at this moment that Ryze felt a slight tremor coming from the underground classroom.

"Aili, go out and check the situation, but be careful not to get spotted," Ryze said, as he precisely added the ingredients and quickly stirred them, then adjusted the flame to medium.

Seeing that the medicine was still clear, he breathed a slight sigh of relief.

Once the most troublesome step is done, all you need to do is wait another ten minutes, and then turn the heat down to low and infuse it with magic once more to complete the brewing of the regular shrinking potion.

He took out his wand and used the time-keeping spell from his family's magic to make sure he didn't miss the last minute.

After exploring the area outside, Ari described the giant's appearance to Ryze.

He was half a head taller than Hagrid, with gray skin, an ugly face, and a bald head.

He was also holding a huge wooden stick that he had found somewhere, and he was causing damage all over the underground passage.

After walking all the way to the Potions classroom, this big guy seemed to smell the potions inside. He first pounded on the door of the Potions classroom a few times, and when he found that the door was locked, he roared and started kicking it hard.

Hearing the sounds of the trolls causing destruction, Ryze knew the locks on the main gate wouldn't hold for long.

He glanced at the timer magic.

There are only three minutes left until the final step of the shrinking drug treatment.

"Three minutes... that's about enough time, let's get it done quickly."

With that, Ryze picked up his wand and began to gather magic at its tip.

At the same moment the troll kicked the potion classroom door, Aery instantly unlocked the door, causing the troll to lose its balance and do a troll split right at the entrance to the potion classroom.

Listening to the troll's horrible howls, Ryze had finished accumulating his magic.

"Final Spark!"

With the consumption of 100 mana points, a laser beam compressed to about five centimeters in diameter shot out violently from the tip of his staff and pierced directly through the giant's chest!

Chapter 64: I thought that troll was someone's prank.

The destructive power of the Ultimate Flash primarily comes from the extremely high temperature exceeding several thousand degrees Celsius at the center of the beam, rather than pure magic. Therefore, it is highly efficient at breaking through ordinary defensive spells.

That is why it was able to penetrate the troll's solid and magically imbued skin.

But the troll lived up to its reputation as a dangerous creature of XXXX. Although the Ultimate Flash pierced its chest instantly with a compressed and concentrated high-temperature beam, the beam was too thin, and since it did not hit its heart, the injury was obviously not fatal.

This pain caused the giant to let out a deafening roar once again.

"As expected, the unfinished magic was still a bit lacking. Otherwise, it wouldn't have just pierced through the chest; it would have melted half of the troll's body," Ryze said with some regret.

According to Professor Flitwick and Ritz's discussion, the current ultimate flash only compresses and converges the light, while ensuring that the beam can maintain an effective attack range of at least ten meters after it is emitted.

Further improvements would involve increasing the power of the beam to make it thicker, and also stacking multiple beams together.

Even if they can't ultimately unleash a massive beam of light thicker than a human like Lux's, they should at least create a beam of light over twenty centimeters long to be considered a success.

As Ryze pondered this, he saw the giant struggling to stand up, clutching its chest.

He casually tapped the troll with his wand, detonating the magical mark left by the Ultimate Flash on its body. This caused a small-scale magical explosion at the troll's wound, blasting the giant out of the Potions classroom.

The magical damage from the magic mark was indeed much less effective on the troll, but the physical impact of the explosion was still considerable, blasting it heavily against the wall outside the potions classroom.

Looking at the giant monster lying motionless against the wall, it must have been completely knocked unconscious by the explosion.

"His magic resistance is indeed very high, probably over 200 in numerical terms, but his physical defense is too ordinary. Just as described in the book, no wonder he could be knocked unconscious so easily by his own stick in the original work. He's such a big guy, but he's wasted his time."

Ryze, who was originally preparing to smash an Arcane Comet onto the opponent's head, commented like this.

Since the other party has fallen, let's stop here.

He had Ellie watch over the troll, and whenever the troll showed any signs of consciousness, he would take a stick and give it a hard whack on the head.

After doing all this, he turned to look at the timekeeping magic.

Even including the time it takes for the magic to charge up, only half a minute has passed, which is plenty of time.

Just as Ryze had calmed his magic and finished brewing the shrinking potion according to Snape's instructions, looking at the clear, bright green potion in front of him, Ryze was wondering whether to test the potion's effects on a troll when a noisy sound came from the underground passage.

"Merlin's beard, Ryze did that all by himself?"

"That's amazing!"

Ryze quickly recognized Ron's voice.

His expression was a little strange. Could it be that Hermione's storyline had shifted to his side?

The Gryffindor cubs realized he wasn't in the Great Hall, so they came here to look for him.

However, Professor McGonagall's voice soon made him realize that the plot had changed.

"The troll has passed out. Ellie is guarding here, so it seems Mr. White is safe."

The next moment, several figures appeared at the entrance of the potions classroom.

At the front was Professor McGonagall, and behind him were the Iron Triangle, whose faces looked somewhat uneasy.

Before Professor McGonagall could speak, Rizzi asked him, "Professor McGonagall, this troll must have come from the dungeons. It tried to break into the Potions classroom to interfere with my potion-making. I don't know if this was some kind of Halloween prank by a Hogwarts professor, so I just knocked it unconscious. I don't think that affected the Halloween atmosphere at Hogwarts, right?"

When McGonagall saw that Ryze looked completely clueless and that the potion in his hand was clear and bright, obviously just brewed, he toned down the blaming look on his face.

“Mr. White, this troll is not some Halloween prank. It accidentally entered Hogwarts. We don’t know yet whether it was put in by another dark wizard, so the entire Hogwarts is currently on high alert.”

She paused for a moment before asking Ritz, "So, Mr. White, why didn't you attend the Halloween dinner? It was Granger who found me and said you might still be in the underground classroom, so we rushed over. Luckily, you're alright now."

Ryze looked at Hermione, who was standing behind Professor McGonagall with her head slightly bowed.

Well, he only remembered to tell Ellie to inform his roommate, and he didn't realize that there was also a Hermione who liked to "meddle".

This meddling isn't meant negatively, because if Rhys were just an ordinary little wizard, he would naturally hope that a classmate would think of him immediately in such an emergency.
