In some fanfictions, the purity potion might be used to test a character's moral purity rather than just blood purity. For example, it could show if a character has pure intentions in their actions.
Some fanfictions might explore the idea of creating a new type of purity potion. This could be a potion that measures not just wizarding purity but also purity in terms of loyalty to friends or commitment to a cause. It could be used as a tool to either unite or divide characters in the story, depending on how they fare when tested by this new potion.
The purity potion can also create conflict between characters. For instance, if one character passes the test and another fails, it could lead to jealousy or discrimination. This can drive the plot forward as characters deal with the fallout of these results. In some fanfictions, a character who fails the purity potion test might be ostracized by their community, which forces them to either fight to regain their standing or find a new place where they are accepted.
Some cool potion ingredients in Harry Potter fanfiction are the fangs of a werewolf. These could potentially be used in a potion to control the werewolf transformation or to gain some of the werewolf's enhanced senses. Moonstone dust is also a great one. It has a connection to the moon and in fanfiction might be used in potions related to lunar magic, like a potion that only works during a full moon. And let's not forget the blood of a vampire. It's a rather dark ingredient, but in fanfiction it could be used in a potion to gain immortality or some form of dark power, although using it would likely be very controversial in the wizarding world.
One interesting concept could be exploring more about the Marauders' time at Hogwarts. Fanfiction might expand on their adventures, like pranks they played that were never mentioned in the original book. Another could be different interpretations of Sirius Black's escape and his relationship with Harry during that time.
Some fanfictions in Harry Potter 2 might play with the idea of the basilisk having different powers or weaknesses. It could also explore the idea of a hidden connection between Ginny and the Chamber of Secrets that goes beyond what was in the original story. There might be fanfictions that change the role of certain characters, like making Neville a more central figure in solving the mystery of the Chamber.
A great plotline in such fanfiction could be a Potion Master being framed for creating a harmful potion. The real culprit might be someone trying to discredit the Potion Master for personal gain, like a rival for a teaching position at Hogwarts. The Potion Master then has to prove their innocence while also dealing with the chaos that the false accusation has caused in the wizarding community. They might have to enlist the help of their students or former colleagues to clear their name.
One interesting 'Love Potion' fanfiction could be about a character accidentally drinking a love potion meant for someone else. This could lead to all sorts of comical and chaotic situations as they start to have strong, uncharacteristic feelings for another person.
One idea could be a story where a young, inexperienced wizard accidentally creates a super - powerful luck potion. This potion not only brings good luck to the creator but also starts to affect the whole Hogwarts in unexpected ways, like making the Quidditch team win every game without much effort or students getting top grades without studying hard.
One interesting concept could be exploring new magical creatures in the Harry Potter kingdom. Maybe there are some hidden species that haven't been discovered in the original series. Another could be alternative forms of magic that are unique to the fanfiction's version of the kingdom. And also, new relationships between different houses or characters can be quite fascinating.
One interesting concept could be the use of magic in relation to physical laws. For example, how spells might interact with gravity. Maybe a levitation spell actually counteracts the force of gravity in a way that can be explained through some made - up 'physics' in the fanfiction.
Well, some fanfictions play with the idea of blood magic in relation to family bonds. They might show how the blood of one's ancestors can be a source of hidden power or knowledge. For instance, a character discovers that their long - lost relative had a special blood - related spell that can only be activated by someone with their exact bloodline. It adds an element of mystery and heritage to the story.
