Rin looked at the tome of sorcery in her hand, a conflicted expression on her face.
Projection Magic, anyone who has watched Fate would know this skill, it can be called the number one cheat skill in Fate, after all, it's a cheat for the protagonist, absolutely quality guaranteed!
After a slight surprise, Rin unhesitatingly opened the cover and quickly read through it page by page. In fact, Rin had also noticed that after her transmigration, her memory and mental capacity were much better than in her previous life. Anything she wanted to remember, she could firmly imprint in her mind with a little attention, and it wouldn't be forgotten for a long time.
Projection Magic (Gradation Air) is an advanced form of Magecraft, superior to Reinforcement and Alteration, and considered the highest difficulty within this system of Magecraft. In the Nasuverse (Moon World), mana is equivalent to a currency of equivalent exchange between humans and the world. Therefore, Projection Magic is also a form of equivalent exchange, where the user can exchange their mana for the physical manifestation of imagined objects, but only as imitations of the originals.
Exchanging mana for imagined things, that is the basic concept of Projection Magic.
The specific casting process is divided into:
Conceptualization
Basic Structure
Composition Material
Manufacturing Technique
Reliance on Experience
Accumulation of Years
In the original story (yuanzhu), the projected weapons, which seemed to appear and disappear at will, were actually created through the operation of all these processes. Therefore, instantly discerning the material, manufacturing process, age, and internal structure of an object became the basic skill for using Projection Magic effectively.
Instantly seeing through the essence of an item, mentally imagining and analyzing all manufacturing processes, and finally, at the cost of mana, summoning the imagination into the real world.
"That looks so difficult… It seems Tsuchimikado (Reference to Shirou Emiya) wasn't as useless as we thought before he met Archer. At least he knew this technique…"
However, even with these conditions met, Projection Magic was still considered useless. Before the appearance of Red A's Phantasm Collapse, this impression was everyone's perception of Projection Magic, including Emiya Shirou himself. Before Red A's guidance, Emiya Shirou's Projection Magic was also useless.
Because the flaws of this technique were too obvious.
Firstly, there's the flaw in a person's impression of the projected object. Projection is a method of reproducing matter through one's own imagination. If there's a flaw in the mind's impression of the projected object, then the projection will also be flawed. In other words, you will inevitably and subconsciously believe that the replica is flawed, thus the projected imitation will be flawed, potentially having far less ability than the original, leading to wasted magical energy. The problem is that human impressions often have too many flaws.
Another issue is consumption. If one's Magic Circuits are insufficient, projection consumes one's own magical energy. If the Magic Circuits are insufficient, the projection's accuracy will also decrease according to the amount of magical energy, even projecting useless junk that only resembles the original in appearance.
Furthermore, only imitations can be projected. No matter how high the accuracy of the imagination, the projected item is ultimately not the original. Therefore, the effectiveness of the projected item can only infinitely approach the original, unable to achieve a complete restoration of the original.
There's also instability. If the original item's mystery is too high, the corresponding magical energy consumed will become enormous, potentially overloading and burning out one's Magic Circuits, or even leading to death. Once a projected item leaves its master, it disappears, and its own existence time is very short. Because projected things are conjured, not inherent to this world, they are corrected by the world, gradually becoming ethereal as magical energy vaporizes, until they disappear.
In summary, this magic is: not high in quality, high in cost, no guaranteed effect, and prone to producing fakes. Turning to the end of the book, Rin also saw a comment: Perhaps this spell is not successful, but it is undoubtedly a bold conjecture and a courageous attempt, worth commemorating.
To put it bluntly, it means that this thing can only be placed in a museum for people to know it exists.
After finishing the entire book, Rin couldn't help but laugh. It seemed no one in this world had yet realized the power of Projection Magic. The reviews disparaged Projection Magic as utterly worthless and useless, but Rin knew how strong this technique truly was, strong enough to allow a human body to contend against a Heroic Spirit!
Although the threshold for learning Projection Magic is high, if one's imagination is precise enough and Magic Circuits are sufficient, the user can potentially unleash abilities close to true magic. This is mainly because Projection Magic can project almost anything except items created by natural gods, and it will also "borrow" the original user's techniques, unleashing unimaginable power, even comparable to a noble phantasm.
For example, in the Heaven's Feel route of Fate/stay night, Shirou, with the help of Red Archer's arm, projected Heracles' noble phantasm, "Nine Lives," which he couldn't use due to his Mad Enhancement. Although it was only the technique that was projected, a single strike was enough to defeat the Blackened Berserker, whose stats were off the charts. This is something most Magicians would find very difficult to achieve.
One-shotting Uncle B, that cheat is simply peerless!
Therefore, Projection Magic is absolutely a very perfect magic. If defense is needed, project a shield or armor. If attack is needed, project a sword, spear, blade, or bow. Project whatever is needed. As long as there is enough imagination and strong enough Magic Circuits, this is a versatile magic!
Therefore, the Magicians who say Projection Magic is useless are themselves useless! Because they lack the ability to overcome the difficulties of this magic. Those so-called flaws can be completely overcome by personal ability.
So what are you hesitating for? Practice!
Rin closed her eyes, raised her right hand, and began to recall the contents of the book, "Fantasy creation concept, basic skeletal structure, formulaic material composition, hypothetical manufacturing technique, historical empirical basis (the original incantation for projection is forgotten, this is original)... Projection start!"
Her entire Magic Circuits instantly began to operate! The atmospheric life force absorbed from the air was rapidly converted into magical energy and flowed towards Rin's right hand. Emerald green Magic Circuits appeared from her shoulder to the back of her hand, and the materialized magical energy current converged into Rin's palm.
A phantom of a sword gradually formed in Rin's hand...
