Well, if Harry has a bone wand in fanfiction, it could completely transform his character's journey. First of all, it might give him access to magic that is not as easily accessible with a normal wand. This could attract the wrong kind of attention, from dark wizards who want to use that power for their own gain. Harry would then have to be more vigilant and learn to protect himself and his wand in new ways. Also, the wand might have a different kind of connection with Harry, one that is based more on instinct and primal magic. This could make his learning process more difficult as he has to adapt to this new way of using magic. His relationships with his friends could also be affected, as they might not understand this new aspect of Harry and his wand.
Perhaps it was related to some new and untamed magical ability within Harry. For example, if he discovered a hidden power within himself that was too much for his wand to handle. His wand, which was made for normal magical use, couldn't withstand the intensity of this new power, and thus shattered.
In many fanfictions, dragon bone wands are rare and sought - after items. Wizards who possess them are often seen as either very lucky or very powerful. They can also be a source of envy among other wizards, leading to conflicts and adventures centered around the ownership and use of the dragon bone wand.
He might choose a phoenix feather because it represents rebirth and magic. And for the wood, perhaps he'd pick holly, which is often associated with protection in the wizarding world.
The story would change drastically. Harry would be without his main means of magic. His enemies might take advantage of this. For example, Voldemort would see it as an opportunity to attack. Harry would have to rely on his wits and the magic he can do without a wand, like some basic spells he might have learned instinctively. His friends would also be more protective of him, and they might have to work harder to keep him safe.
The plot would change drastically. First, Harry would be in a vulnerable position. His enemies might take advantage of this. Second, he would need to quickly adapt. Maybe he'd start looking for an alternative magical tool or way to cast spells. Third, his relationships could shift. His friends might have to protect him more. Overall, the story would move from a more traditional wizard - based plot to one of survival and adaptation.
The wand maker's character can be developed by showing their passion for their work. For example, they could be shown spending long hours in their workshop, carefully selecting and carving each wand. This would show their dedication.
The different wand might change his abilities in terms of spell specialization. Say the new wand has a different wood that is attuned to certain types of magic. If it's a wand made of willow, which is often associated with healing magic, he could find himself more proficient in healing spells, even if he wasn't before. This would be a significant shift in his magical abilities as he would be able to contribute in a different area of magic within the wizarding world.
The dragon core wand might make Harry more confident. Knowing he has a powerful wand could boost his self - assurance in his magical abilities. For example, in duels, he might stand taller and be more assertive.
His second wand could be made of different materials. For example, his first wand was holly and phoenix feather, but the second might be made of yew and unicorn hair. This difference in materials could lead to different magical properties.
Well, it might make some characters fear him. Since the Elder Wand is so powerful, some wizards could be worried that Harry might become too powerful and turn to the dark side. For example, the Ministry of Magic might keep a closer eye on him, which would strain his relationship with them.
