What could be an interesting plot in a 'Mix of Mana and Od Fate Stay Night Fanfiction'?

For a character like Rin, her understanding and use of mana could be enhanced by the introduction of od. Maybe she starts to question her traditional magical training when she discovers the power of this combination. This could lead to her developing new spells or techniques, and also a more open - minded view of magic in general.

Well, perhaps in this crossover fanfiction, the power systems of both could merge. For example, the magical abilities of the Fate Stay Night characters could combine with the Freezing characters' abilities. Let's say Saber's Excalibur could be enhanced by the energy manipulation skills of a Freezing character. And there could be a love triangle between a Fate Stay Night male character, a Freezing female character, and another character from either universe, which adds a lot of drama to the story.

In a Fate Stay Night Skyrim crossover, Archer could be summoned by a powerful mage in Skyrim. Archer would find the concept of the Thu'um fascinating as it's a form of magic he's never encountered. He could start exploring Skyrim, looking for ways to use his own abilities in conjunction with the local magic. He might get involved in the civil war between the Stormcloaks and the Imperials. His strategic mind could help whichever side he decides to side with. And when the dragons return, he could use his Unlimited Blade Works to create weapons specifically designed to fight dragons, like blades that can pierce dragon scales more easily.

A great plot could involve the magic systems of both universes colliding. For instance, the spells in Harry Potter and the magecraft in Fate Stay Night. The Grail in Fate Stay Night could be related to a powerful and dark magical artifact in the Harry Potter world. Characters like Shirou could meet Hermione, and they could compare their knowledge of magic. Shirou might learn some new spells from Hermione, while Hermione could be intrigued by Shirou's ability to reinforce objects. This could lead to a joint effort to stop a common threat that is using the combined power of both magic systems for evil.

A fascinating plot aspect in such fanfiction is the idea of the Holy Grail War in the Naruto universe. Picture the ninja villages competing for the Grail. The characters from Naruto would have to form alliances and strategies similar to what happens in Fate Stay Night. Also, the concept of summoning Servants in the Naruto world. What if Naruto or Sasuke could summon a powerful Servant? How would they interact? And how would the Servant adapt to the ninja world? These are all really interesting plot elements.

In the Fate Stay Night visual novel, mana transfer is a crucial concept. It is mainly related to the relationship between Masters and Servants. Masters provide mana to Servants, which is like the energy source for Servants to exist and perform their powerful abilities in the Holy Grail War. Without sufficient mana transfer, a Servant may not be able to function at their best or may even disappear.

Perhaps a plot where the Holy Grail War from Fate Stay Night gets disrupted by the arrival of some key players from Fate Apocrypha. This could lead to new alliances and rivalries. Like Shirou from Fate Stay Night having to team up with a character from Fate Apocrypha, say Sieg, to face a common enemy that is after the power of the Grail in both their worlds.

Personally, I think the development of the relationship between Shirou and Saber is one of the most interesting plots. Their different outlooks on life and values gradually change as they interact more. Also, the battles in the Holy Grail War, like the ones where the Servants use their unique abilities, are really exciting and add to the overall appeal of the story in the Fate Stay Night Novel.

Perhaps in this fanfiction, Shirou discovers a hidden power within himself during the 4th War. This power might be related to his ideals of being a hero. He could use this power to try and stop the more malicious servants from causing too much destruction. For example, he might be able to counter Gilgamesh's arrogance with his newfound strength.

The visualization of mana transfer in the Fate Stay Night visual novel is quite interesting. It can be seen in the form of auras or energy streams. When a Master sends mana to a Servant, the visual novel may show a soft light or a series of lines connecting them, indicating the flow of mana. Also, the expressions on the characters' faces, like the Master looking a bit tired and the Servant looking more vibrant, can be part of this visualization.
