He might choose holly. In the original series, Harry's wand has a holly wood. Since he's making his own in this fanfiction, he could still be drawn to it for its traditional associations with protection and courage.
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.
In fanfiction, his wand could potentially be used to reveal secrets. Snape was full of secrets himself. Maybe his wand could be a key to unlocking hidden chambers or revealing long - lost knowledge. It could be used to decrypt old spells or manuscripts that were crucial to the wizarding world's history.
Perhaps in the fanfiction, Hermione's motivation for making her own wand comes from a need to break free from the norms of the wizarding world. By creating her own wand, she could be exploring uncharted magical territory and discovering new ways of casting spells that are more attuned to her intellect and power.
Well, he starts by going into the Forbidden Forest. There, he communes with the trees, seeking one that calls out to him. Once he finds the perfect tree, he uses his magic to gently remove a branch. He then spends time carving and molding the wood, all the while focusing his magic into it. For the core, he might go on a quest to find a special magical creature from which to obtain a suitable element. After getting the core, he combines it with the wood in a ritualistic way, using his most powerful spells to bind them together.
One scenario could be Snape using his wand to communicate with the dead. Maybe he discovers a spell that allows him to use his wand as a conduit to speak to Lily Potter. This would add a whole new layer to his character, as his love for Lily was a major driving force in his life.
The wand crafted by Merlin for Harry is special because it's not just a tool but a symbol of a connection between two great magical beings. Merlin, with his age - old wisdom, imparts a certain quality to the wand. It could have a unique resonance with Harry's soul. The materials used are likely to be of the rarest kind, and the way Merlin enchants it gives it an edge. It might be able to adapt to Harry's growth in magic more easily than other wands, and it could have hidden powers that are revealed as Harry faces different challenges in the fanfiction.
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.
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.
In fanfiction, Harry with a different wand can lead to all sorts of interesting scenarios. Maybe the wand has different magical properties that he has to learn to control. For example, it could be more powerful in certain types of magic but less so in others. This would force Harry to adapt his magical techniques.
