The agreement between Ivy and Harry was quite simple.
Since Harry only needed to attend three Quidditch practices per week, the Firebolt 2000 often just sat in his dormitory, and Ivy could take this opportunity to study the latest broomstick model.
In exchange, Ivy only had to help with homework for all subjects except for Defense Against the Dark Arts.
Harry and Ron had asked why Ivy never did his homework for Defense Against the Dark Arts.
Ivy's response was, "Because of Voldemort's curse, the professor of this subject usually doesn't live long enough to see the end of the semester, so there's no point in doing homework for someone who's destined to fall."
"Cool." Ron nodded approvingly, "If it weren't for the fact that my mum sends me howler letters, I wouldn't bother with Defense Against the Dark Arts homework either."
To study the broomstick properly, Ivy also found a very useful skill in the Book of Destruction—the creation of magical artifacts.
The skill of creating magical artifacts allows a caster of level 3 to use magic to create qualified magical items, but it requires time, money, and experience. Of course, the materials for these magical items need to be sourced separately.
Ivy was very interested in this.
After failing to merge wizard magic with DND wizard spells, Ivy decided to use artifact creation as a way to combine the magic from both worlds into one object.
His idea was simple: endow an artifact with the ability to fly.
For example, if he could transfer the ability to cast Evocation spells into a crystal ball and then use wizard magic to make it fly, could he recreate the appearance of the blood mage Kael'thas?
If this magical artifact crystal ball had three versions—one that could cast lightning, one for fire spells, and one for freezing spells—wouldn't that be just like the Seeker Carl?
Excited by this idea, Ivy immediately threw himself into the research.
The first thing to solve was dismantling the broomstick.
Of course, Ivy didn't have any relevant work experience, but Scholar's Touch and Artifact Creation would solve everything.
The former allowed him to instantly read the Flying Broom Maintenance Manual, and the latter gave him the ability to repair the broomstick.
After some preparation, Ivy didn't hesitate to disassemble Harry's Firebolt 2000 completely.
Fortunately, this was happening in the Room of Requirement, so Harry wasn't watching. If he had been there, he would have been panicking like a teapot with each part of the Firebolt being taken apart.
The structure of the broomstick wasn't complicated. It consisted of the wooden shaft, the twigs, the footrest, and the metal rings that held the twigs together.
But when these ordinary components were imbued with magic and then combined, it became a wizard's flying device.
There were many interesting magical principles involved. First, there were protection spells to safeguard the patent charm and the broomstick structure. This could protect it from minor dark magic attacks, but in Ivy's hands, it was practically useless.
Next was the shock-absorbing and cushioning spells on the footrest and seat, which prevented the witch or wizard riding the broomstick from falling off during high-speed flight.
Finally, there was the flying charm on the twigs and the braking charm on the metal rings, which formed the broomstick's propulsion and braking system.
The most interesting part was the flying charm on each twig. Every wooden twig had its independent flying magic, and when they were fixed together by the metal rings, their individual magical effects combined to create a flying spell that could lift a wizard into the air.
Ivy believed the most crucial part of the broomstick was the flying charm at the tail and the braking charm, as they ensured the broomstick's speed and maneuverability.
All Ivy had to do was apply these spells to the artifact he was about to create—after all, he wasn't planning to ride it himself.
Finding the right materials for an artifact was no easy task. The items stored in the Book of Destruction were either too precious or too common, and none of them were quite suitable. Plus, Ivy's experience points couldn't support endless trial and error.
But then, his silver linden wood wand gave him a new inspiration.
Why not use biological materials to craft artifacts? Just like Ollivander uses unicorn tail hair to make wands, perhaps materials from magical creatures could yield extraordinary results.
The Forbidden Forest at Hogwarts, which Ivy knew like the back of his hand, turned out to be the perfect place for this.
That night, Ivy embarked on an unprecedented quest to find magical materials in the Forbidden Forest.
What he discovered was a magical creature he had never encountered before—an eight-eyed giant spider.
Over a hundred years ago, the Forbidden Forest had been filled with spider nests. Ivy had spent a lot of effort clearing them all out when he was using dark magic to combat poachers.
But now, a much stronger species of magical spider had taken over the forest, pushing other magical creatures out of their habitats.
So Ivy was more than happy to eliminate them.
These eight-eyed giant spiders were full of valuable materials. Not only was their venom a hot commodity on the black market but their giant pincers and eyeballs were also useful for crafting artifacts.
Ivy, undeterred by the sticky and wet giant spider eyes, drew inspiration from ancient magic. He used a clever petrification spell to turn these recently removed tissues into crystals.
Together with a miniature core forged from fairy silver, the crystallized giant spider eyes became excellent magical materials.
Contrary to Ollivander's approach of using biological materials to craft wands, Ivy used metal to wrap the magical creature materials. This combination had extraordinary magical conductivity and worked well with the magic from both worlds.
The crystallized giant spider eyes carried the flying charm and braking charm, allowing the artifact to freely fly under the caster's control, almost like a floating magical cannon.
As for the fairy silver core inside, it was akin to a level 3 Fireball necklace in the DND world, capable of casting seven Fireballs a day.
Yes, dealing with the eight-eyed giant spiders gave Ivy experience points and earned him a level 3 spell slot.
Originally, he had only intended to create a few magical orbs capable of firing Fireballs or casting the Thunderstrike spell, but a large amount of experience points pushed him to take a gamble, and he succeeded in creating what he called the Elemental Orb.
These three orbs, each the size of an adult's fist, appeared as solid black crystal balls when inactive. Once in standby mode, they began emitting elemental glows and floated around the caster's shoulders.
With the flying and braking charms, the orbs could fly freely within a certain range of the caster and unleash Fireball bombardments from a greater distance. Furthermore, during their creation, Ivy used his wizarding expertise to alter the Fireball's damage type. Thus, the three orbs had attributes of Fire, Ice, and Lightning.
In a way, he had created something like the Seeker Carl.
Looking at the spectacular visual and sound effects of the orbs, Ivy nodded in satisfaction.
