It was only when the complete wand was in Luke's hand that he felt something different.
If the magic power within his body was like water in a reservoir, then the wand was the valve controlling the water's outflow from the reservoir, and his previous wandless casting was like digging a hole in the reservoir.
Although water could still flow out, the outflow was uncontrolled, and even a slight mistake could lead to a dam burst and a flood, causing serious magic accidents and endangering his life.
More importantly, for magic of the same power, the magic power consumed with a wand was only one-tenth of that used in wandless casting, the magic output was stable and continuous, and the difficulty of casting was greatly reduced.
Luke held the wand tightly with joy; with this wand, his strength could be further enhanced.
Luke was never a stubborn person who believed wandless casting was superior to wand casting. After all, the reason humans are more advanced than other animals is because they can think and are good at using tools.
Just as the wand is to the Wizard, it is because Wizards can use wands that they are able to overpower various magic creatures and become the masters of the magic world.
Otherwise, if it were solely about wandless casting, many magic creatures in the Harry Potter world are born with magical abilities, such as Goblins and House-elves, who can perform wandless casting and can ignore Anti-Apparition jinxes to appear in places like Hogwarts.
But one became a bank manager for Wizards, and the other became a servant for Wizards, both existing dependent on Wizards.
Of course, Luke would not give up practicing wandless casting just yet, as there's always a 'what if' scenario; without a wand, he wouldn't become a Squib who couldn't cast any magic.
With the wand, Luke excitedly tried all the magic he had learned, and basically, all of them succeeded on the first try, and their power was stronger than before.
Tom and Goldberry also witnessed Luke's wand-making process firsthand. Seeing Luke cast various magic effects with the wand, Tom immediately became interested and wanted Luke to let him play with the wand.
Luke handed the wand to Tom and taught him a few spells. He was also quite curious if Tom could use the wand.
Tom waved Luke's wand, and golden notes flew out from the wand's tip, emitting joyous music filled with magic. The music grew louder as the golden notes spread, gradually echoing throughout the entire forest.
Under the influence of the music, the resentful trees had their grievances appeased and became peaceful.
Luke, who was closest, felt it most deeply; under the influence of the music, he became incredibly joyful, and this joy was not like the effect of having taken a cheering charm, but rather a joy that originated from his heart.
It was as if, surrounded by this music, he became fearless, and no sadness or negative emotions could affect him anymore.
What surprised Luke was that Tom could use the wand, even playing very beautiful magic music with it, but he couldn't cast Luke's spells.
According to Tom, while he could produce magic with similar effects, the essence of this magic differed in principle from Luke's spells.
Luke was not surprised by this, but he was now more curious about Tom's musical magic.
This musical magic seemed to have no destructive power, but Luke saw its potential and utility; it could remove negative emotions from people, filling them with joyous and positive emotions. Such magic could completely resist the negative effects brought by the Dark Arts.
Although Luke had not yet learned the Dark Arts, he knew that while the Dark Arts were powerful, they would inevitably have negative effects on the caster, potentially leading to the distortion of appearance, soul, and even mind.
That's why the magic world has repeatedly and strictly forbidden the Dark Arts; if one uses unforgivable Dark Arts like the Killing Curse, they will be imprisoned in Azkaban.
Luke had a premonition that as he signed in at more places in the future, he would definitely acquire Dark Arts spells. If he wanted to become stronger, he couldn't abandon the study and use of the Dark Arts.
Therefore, when he encountered this musical magic that could generate positive and joyful emotions, Luke was moved.
He shamelessly asked Tom if he could learn this magic.
And Tom readily agreed.
But what Luke hadn't expected was that Tom's first lesson in musical magic was to have him learn to sing along with him.
According to Tom, this musical magic has no specific spell; instead, it is music that comes from the heart. Therefore, to successfully cast it, one needs to sing loudly, and with emotion; the stronger the emotion, the more powerful the magic effect.
Luke didn't have a terrible voice, but it wasn't particularly good either. So, with a sense of shame, his face flushed, he followed Tom word for word, learning to sing, and was constantly reminded by Tom to sing with emotion.
Under the guidance of Tom, his music teacher, Luke sang haltingly.
And Goldberry sat among the water lilies, weaving cloth while smilingly watching the lively scene between the two.
Finally, Luke learned this musical magic. As he waved his wand, nimble golden notes darted from the wand's tip, hopping and skipping, emitting cheerful music.
However, unlike Tom's music, which could spread throughout the Old Forest, his golden notes could only produce music at close range.
But Luke was already very satisfied.
Moreover, besides using the wand, Luke could also achieve the same magic effect by singing.
The difference between the two was more like singing in one's heart versus singing with one's mouth.
However, compared to the socially embarrassing method of singing aloud, he preferred to express it with a wand.
After staying with Tom for a long time, Luke now had his first wand and had learned musical magic. With ample preparation, Luke officially bid farewell to Tom and Goldberry, preparing to go to the Barrow-downs.
His purpose in going to the Barrow-downs this time was not only to find the sharpest tools for carving the iron-hard tree hearts. Another part of the reason was that he also wanted to see if he could sign in at the Barrow-downs.
Perhaps because they had lived long enough and experienced too many partings, the couple did not try to hold Luke back too much when he said goodbye.
At the time of departure, Tom gave Luke a map of the Barrow-downs that he had drawn, and also marked the location of the sharp tools he wanted to find. The clear and precise location made it feel as if Tom had really been there.
Goldberry, on the other hand, prepared a perfectly fitting black Wizard's cloak and robe with silver trim for him. The material was woven from black swan feathers and silver thread, and the style was inspired by other Wizards in Middle-earth.
Moreover, Goldberry had blessed it; the robe had the effects of being durable and clean, and the cloak also had the ability to conceal, making him easily overlooked and less likely to be targeted when he wore it.
Receiving such a precious farewell gift, Luke was overwhelmed.
"Goldberry, this... this is too valuable!" Luke was surprised and moved. He hadn't done anything for the two of them, yet he had received such kindness.
"Take it," Goldberry said with a gentle smile, pressing the robe and cloak into his arms. "This is from Tom and me. Your future is destined to be a journey of constant movement. We hope this gift brings you a little warmth."
Tom, standing nearby, also said, "Take it, Luke. Don't disappoint Goldberry's kindness; she spent several days weaving it."
Luke finally accepted the gift, and at their persuasion, he immediately changed into the robe and cloak.
Luke's previous clothes were the ones he had worn when he transmigrated, and they had only remained intact thanks to repeated mending charms.
Now, dressed in new attire, his entire demeanor changed. Enveloped by the black cloak and robe, he looked incredibly mysterious.
He truly looked like a genuine Wizard.
