If Harry Potter snapped his wand in fanfiction, it would be a huge turning point. Maybe he'd start a journey to repair it, like finding some ancient magic or a powerful wizard who could fix it. Or he could discover latent powers within himself that didn't rely on the wand. It would be a great opportunity for the writer to explore different aspects of Harry's character and the magic world without the typical wand - based magic.
If Harry Potter snapped his wand in fanfiction, the plot could take a really interesting turn. Harry would be at a significant disadvantage. Enemies might see this as an opportunity to attack him. However, this could also be the start of a new adventure. He could go on a quest to find a magical artifact that could replace the function of his wand. Along the way, he would face numerous challenges and learn more about the deeper secrets of the wizarding world. This could also affect his relationships. Some might distance themselves from him, while others would stand by him more firmly, adding more drama to the story.
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.
If Harry Potter snapped his wand in fanfiction, one possible scenario is that he would need to find a way to repair it. There are many magical creatures and objects in the wizarding world that could potentially help with that. He might search for the Phoenix whose feathers are used in his wand, hoping it could assist in mending it. Another possibility is that this event could be a turning point in the story where he realizes that his true power doesn't solely lie in his wand but within himself. So he could start to train in magic that doesn't require a wand, like wandless magic that some powerful wizards are known to perform.
Another idea for a fanfiction could be a side character, like Neville Longbottom, having his wand snapped. Neville is often underestimated, and this could be a chance for him to prove his worth even without his wand. He could turn to herbology and use his knowledge of magical plants to create makeshift magical tools or find a way to repair his wand using rare plants. It would show his resourcefulness and determination.
There might be a fanfiction where a snapped wand is a symbol of a broken magical bond. For example, a wizard's wand snaps during a fight with a dark wizard who was once a friend. The story could then focus on how the wizard overcomes the emotional turmoil and the loss of power, and perhaps even tries to repair the relationship as they attempt to repair the 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 the fanfiction 'Wandless in the Shadows', Harry's wand snapping leads him to a secret society of wandless magic users. They teach him their ways and he becomes a part of their fight against dark forces that want to control all magic. It's full of mystery and action. Another good one is 'The Snapped Wand's Legacy', which explores how Harry's broken wand affects the balance of magic in the wizarding world and how he tries to set things right.
He might have lost his main means of casting spells. This would put him at a great disadvantage in any magical battles or challenges. Without his wand, he would have to rely on other forms of magic or his natural abilities, which could be much more difficult.
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.
