A possible fanfiction could be set during a war. The good side is losing until a powerful wizard creates a new variation of the lightning spell. This spell is so powerful that it can turn the tide of the battle. But the wizard has to train others to use it quickly while also fending off attacks from the enemy.
One idea could be a story where a young wizard discovers an ancient and forgotten lightning spell. He has to master it in secret because the spell is considered too dangerous by the Ministry of Magic. As he learns more about the spell, he uncovers a plot that the spell is key to stopping.
Perhaps a fanfiction where a group of students compete in a magical tournament. One of the challenges involves using the lightning spell in a creative and controlled way. A shy student, who has been secretly practicing the lightning spell, surprises everyone with her skills and determination in this task.
One idea could be creating a new spell that combines the elements of existing ones. For example, a spell that has the speed - enhancing aspect of the 'Accio' spell and the protective shield - creating part of the 'Protego' spell. Another idea is to write a fanfiction where a character discovers an ancient, long - forgotten spell and has to figure out how to use it properly. It could lead to all sorts of adventures and challenges in the wizarding world.
One interesting idea could be a new spell using lightning magic that only a chosen few can master. It might be a spell that can either protect Hogwarts in a more powerful way than existing spells or be used to track dark wizards by following the electrical impulses in their magic.
One idea could be creating a spell that allows the caster to communicate with magical creatures in their own languages. For example, it could be used to negotiate with a hippogriff or understand the complex social structure of the house - elves through their conversations. Another idea is a spell that can reverse the effects of dark magic without harming the victim. This would add an interesting plot point if a character has been affected by a dark curse and the protagonists have to find or create this new spell to save them. A third idea could be a spell that temporarily gives the caster the ability to fly without a broomstick, which would open up all sorts of adventure possibilities like exploring hidden parts of Hogwarts from the air or chasing after a flying enemy.
One idea could be a story where a character accidentally uses a modified memory spell on themselves and starts to forget important things about their magical abilities. They then have to race against time to reverse the spell before it erases all their knowledge. Another plot could involve a dark wizard using a powerful memory spell on the entire wizarding world to make them forget about a certain dark prophecy. And a third idea might be a young witch or wizard using a memory spell to help a Muggle friend remember a near - death experience they had with magic, but things go awry when the Muggle starts to remember too much and attracts unwanted magical attention.
One possible plot idea could be a character suddenly developing a new magical power similar to the speed and unpredictability of a lightning bolt. For example, a young wizard who has always been mediocre in magic suddenly discovers they can move at lightning - fast speeds during duels, turning the tables on their opponents.
In some fanfictions, there could be a story where the Lightning Bolt scar has a mind of its own and communicates with Harry in times of danger, guiding him through difficult situations. This adds a whole new layer to Harry's character and his connection to his past.
Well, one plot could be a student accidentally shrinking the Hogwarts castle while practicing the shrinking spell. It creates chaos as everyone has to navigate the now - tiny corridors. Another plot might involve using the shrinking spell on magical creatures to study them more closely in a safer, smaller form. And there could also be a plot where a villain tries to use the shrinking spell to hide important magical artifacts in a minuscule size, and the heroes have to find and enlarge them.
In harry potter summoning spell fanfiction, a common concept is the evolution of the summoning spell. Some stories might have characters modifying the traditional summoning spell to make it more powerful or specific. For instance, instead of just summoning a book, they can summon a particular page within the book. Also, there could be the idea of summoning living creatures in a different way than in the original series. Instead of using the regular animal - summoning spells, a new and more complex spell for summoning mythical or endangered creatures might be created.
First, study the existing lore about magic in the Harry Potter world. Know how spells are typically cast, what the limits are. For the lightning spell, think about its power and potential uses. Then, create interesting characters. Maybe a character who is afraid of the lightning spell at first but has to overcome that fear. Keep the story flowing with a clear plot.
One interesting plot could be a new adventure where Harry discovers a hidden power related to lightning that was unknown in the original series. This power might help him face a new dark wizard threat.
