Harry would begin by researching different wand - making techniques. He'd study ancient texts in the Hogwarts library. After that, he decides to use a combination of traditional and his own unique methods. He travels to different magical places to gather the materials. For the wood, he visits an old, enchanted grove. He uses his wandless magic to cut and shape the wood. As for the core, he makes a deal with a magical being to get a special, rare core. Then, he uses his deep understanding of magic and his own personal connection to magic to fuse the core and the wood, creating a wand that is truly his own.
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.
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, Harry could also be inspired by the wand - making techniques of Ollivander. He might study the way Ollivander selects woods and cores. Then, he'd start his own process. He could use his connection with the wizarding world and his friends. For instance, Hermione might help him research the history of wand - making, and Ron could be there to support him during the more dangerous parts of gathering materials.
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.
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.
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.
Wand inheritance in this type of fanfiction could also be influenced by prophecies or family legacies. Maybe there's a prophecy that only a certain member of the family can inherit a particular wand at a specific time. Or perhaps the wand has a long - standing family legacy attached to it, and only those who uphold the values of the family can successfully inherit and wield it.
Maybe he discovers some ancient spells or incantations that don't need a wand. These could be spells that were forgotten over time but are still effective. He spends time researching in old books and uncovers these wand - less magic techniques.
In many fanfictions, it serves as a major turning point. It might be the catalyst for Harry to discover hidden powers or to make new alliances. For example, he could be forced to seek help from a reclusive wizard who has knowledge about wandless magic. This encounter could open up a whole new storyline about the history of magic and how it can be harnessed without a wand, greatly influencing the overall plot of the fanfiction.
Perhaps he barters with magical beings. He could offer his services in solving magical problems for them in exchange for rare building resources. For example, he might help a group of centaurs with a prophecy issue and in return, they give him enchanted wood or special stones. He may also get help from his friends who have access to different resources. Hermione might provide some rare books with building spells, and Ron could get some things from his family's old collection.
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.
