In fanfiction, Harry could use the law to gain political power. By understanding and manipulating wizarding laws, he can rise within the Ministry of Magic or other governing bodies. He may use laws regarding inheritance or magical heritage to his advantage, perhaps to claim certain positions or resources. This would change his role from just a hero against dark wizards to a political figure within the wizarding world.
He might use it for protection. For example, if someone tries to harm him or his friends, he uses laws about magical self - defense to stop them.
Often, Harry uses the law to uphold justice. He might come across a situation where an innocent wizard or witch is being wrongly persecuted. Using his knowledge of the law, he can find loopholes or evidence to prove their innocence. This could involve laws related to spells and their proper use, or laws about magical artifacts and their ownership.
In Harry Potter fanfiction, the application of marriage law can vary greatly. Some fanfics might follow the wizarding world's own traditional 'rules' of marriage which could be different from Muggle marriage law. For example, there could be magical contracts involved in wizarding marriages that are not present in the Muggle world.
In some fanfictions, Harry Potter uses his strong emotions and willpower to perform wandless magic. For example, in times of extreme danger or when he has a very intense desire to protect someone, he can tap into his inner magic without the need for a wand.
Well, in some fanfictions, Harry Potter might use the bo staff for self - defense. He could twirl it expertly to deflect spells and attacks from dark wizards. It might also be used in a more acrobatic way, like he jumps and spins while using the bo staff to create a sort of protective shield around himself.
In fanfiction, it could be that the snake has a symbiotic relationship with a certain type of magic that is beneficial for healing. Harry Potter uses his knowledge of magic and his bond with the snake (through Parseltongue) to tap into this. The snake might be able to detect imbalances in a person's magic or body and then use its own magic to correct them. Harry, understanding this, guides the snake in the process, much like a healer would use a tool or an ingredient in a complex healing ritual.
Harry Potter could use his money to improve Hogwarts in fanfiction. He might donate to renovate old classrooms, buy new equipment for the library or even fund extra - curricular activities for students. After all, he has a strong connection to the school and wants to give back.
Often, he uses his deep understanding of magic theory. Since he's learned a great deal about magic at Hogwarts, he can apply that knowledge in a wandless way. He might use incantations silently and with just a wave of his hand or a focused thought, as seen in fanfictions like 'The Wandless Path of Harry'. Here, he spends a lot of time researching and practicing wandless techniques based on the spells he already knows.
In many fanfics, Harry Potter might learn about money management through lessons or experiences at Hogwarts.
It makes him more cautious. Since he knows the law, he's aware of the consequences of his actions more than ever. So he might think twice before using certain spells or getting involved in risky situations.
It could be that his training in magic somehow awakens his haki. As he delves deeper into advanced magic spells and combat training at Hogwarts, his body and mind start to develop this new ability. For example, during a particularly intense dueling session, he feels a strange energy coursing through him which he later realizes is haki. His professors might initially be baffled by this new power, but as he learns to control it, it becomes an asset in his battles against the forces of evil.
If Harry uses a flask to store a powerful antidote, it can save the day when someone is poisoned. This changes the plot by preventing a character's death and leading to new developments in the story.
