Here is a small magic circuits/circle component list.
"As a magus I am envious of those with properly working magic circuits. I am only doomed to broken circuits that only allow me to release "sparks", such misfortune had been a result of my ancestors' infidelity. I will never know what I am truly capable of, but any successful magus will make do with what they have at their disposal."
kotomine-kirei:
“Before you go..” Kotomine stopped the young man abruptly as if waiting for the perfect moment to say that. As the young man turned to face the priest again, he continued. “..you never told me your name. I won’t ask further if you wish to withhold that information, but otherwise it would only be common courtesy to name yourself after I did.”
Kotomine used the distraction of that young man, to better look at him, in a spiritual sense. His aura was not particularly overwhelming, but it was not that of a normal human either. Indeed, he was probably blessed with Magic Circuits. Whether the young man realized that or not, Kotomine could not say. Only that if he did..perhaps things would turn out to be interesting, perhaps for both of them. If he didn’t however..then sadly, only that broken priest would be able to find joy at altering this young person’s life completely by disclosing that information in due time..
Togusa faced Kirei with a mild shiver running through his chest. Disclosing his name was something Togusa had not intended to do. No. This interaction. None of it went according to plan or expectation. He opened his mouth once. As he began to speak, Togusa inhaled deeply disrupting his speech.
Damn, he makes a pretty good point. I don't have a choice now, do I?
"T-Togusa. Kiribito Togusa."
There. I said it. Now to disappear forever.
Overwhelming anxiety shook him to the bone, which made his knees buckle and quiver. He never felt more ready to leave a place since moving into his new home. Something about a stranger knowing his name made him feel uneasy, paranoid even — the headache was getting worse. It made his eyes start hurting enough for him to avert his gaze from Kotomine's bland, soulless hues. Though, he could still feel the man's eyes fixated on him. Togusa was marked — the two would definitely cross paths again. Though, it wasn't something Togusa wanted to accept.
do you think that shiro or archer could remake there magic curcuit if it was ever destroyed? i belive he could since when he first started useing magic dident he create a new magic curcuit everytime?
"Go on, kid; explain how to 'create' a magic circuit."
"Shut up, you! You know you were just as confused as I was in your time! Ugh... Anyway, what I was doing before Archer corrected me wasn't proper thaumaturgy. One does not create a magic circuit every time he uses use magic, as I once thought. The circuit is as much a part of a magus as their nerves. It's something that can't be replaced. Destroying someone's circuits takes a unique type of magic, such as my father's Origin bullets. Personally, I can't even consider what it would be like if I lost mine. My Reality Marble is my own mind, so I might not even survive such a tragedy."
