In the fanfiction, Harry might learn the etiquette of dueling. This could include proper pre - duel salutations and post - duel respect. He could also learn about the etiquette of using magic in public places. For example, there might be rules about not using certain flashy spells during normal daily activities. And he might be taught the proper way to interact with magical creatures, like bowing to a centaur or offering a gift to a hippogriff.
One interesting lesson could be table manners in the wizarding world. There might be specific ways to hold a wand while dining or proper incantations to say before and after a meal. Another could be how to address different levels of wizards and witches, like the proper title for a powerful elder wizard. And perhaps the correct way to enter and exit a magical room or building, which could involve specific spells or gestures.
His learning of etiquette might initially cause some strain. His Gryffindor friends are used to his more laid - back ways. But as he becomes more refined, he starts to interact better with students from other houses. For instance, he could have more civil conversations with some of the Slytherins who value proper behavior. This could slowly change the dynamic in the common rooms and in classes, as people start to see Harry in a new light.
One of the interesting spells could be 'Tempestus Ignis' which creates a fiery storm in some fanfictions. It gives him a powerful offensive move against dark creatures.
There could be a book of ancient runes that holds the key to powerful spells. Another might be a tome about magical beasts, which gives Harry a better understanding of how to deal with them magically. And perhaps a book on forgotten magic arts that provides him with unique ways to use magic.
In some fanfictions, Harry might use necromancy to bring back important figures like his parents. This could lead to complex emotional and moral dilemmas as he tries to interact with them in a world that has moved on without them.
One interesting story could be Harry's initial struggles. He might face challenges like accidentally causing chaos as he tries to control his wandless magic. For example, he could make objects fly uncontrollably in the Gryffindor common room. Another aspect could be his secret training sessions. He might find a hidden place in Hogwarts, like an abandoned classroom, to practice without others knowing.
Another idea could be Harry learning magic from a time - traveling wizard from a far - off future. This would introduce futuristic magical concepts and technologies that he would have to adapt to. It could also lead to him having to use his traditional Hogwarts magic in new and unexpected ways to keep up with the advanced magic he's learning.
There are fanfictions where he learns elemental magic in a new way. For example, being able to combine fire and water magic in a unique and powerful way that was not explored in the original books. He could use this to create new defensive or offensive spells against dark wizards.
In some fanfictions, there might be a plotline where Occlumency lessons lead to unexpected friendships. For example, a Gryffindor and a Slytherin are paired up for Occlumency practice and end up understanding each other better. Or perhaps a character discovers that their Occlumency abilities are linked to a long - lost family magic, which then sets them on a journey to uncover their family's past.
Well, in fanfiction, one key element is the way purebloods interact with each other at formal events. They often use formal language and have strict rules about greetings. For example, a proper bow or curtsy might be required when meeting an elder pureblood.
One great plot development could be that the elemental magic Harry learns is not part of the traditional Hogwarts curriculum. So, he has to seek out hidden mentors or ancient texts. This could lead to him exploring parts of the wizarding world that are long forgotten. As he delves deeper into elemental magic, he might also start to question the limitations of the magic he has been taught so far at Hogwarts.
