You can keep saying that but... there's no evidence in the story? The story tells us she's at full power with Lola Stuart's body. Mashing together other religious things to try and explain the discrepancy just makes more bullshit.
Where the fuck did you get that? How did you come to the conclusion that Coronzon is at the peak of her powers when she uses her avatar? Do you think I invented the concept that the human body stabilizes the soul?
A twisted woman's smile appeared on the surface of the hair that twisted into the shape of a spear or spike.
"If I was just any old demon, that weakening tactic probably would have worked. Much like it did for Magic God Othinus when she was critically damaged by human hands."
There was a voice.
A wicked voice came from the base of the golden hair beyond the veil of light.
She reminded them of her position and what the title of Great Demon meant.
She seemed to be forcibly distancing herself from something that could never be broken down once it was accepted into the heart.
"But I am Great Demon Coronzon, the only demon to have gained my own body of flesh and blood. Not even Satan and Beelzebub could manage that. The tree is not just to ascend. Descending it every once in a while can be fun. For better or for worse, this cage of flesh stabilizes my soul and makes me sturdy enough to remain unshaken when I command an energy very similar to Telesma."
Telesma could be used to perform a safe summoning by cutting away a small amount within a temple. It could also be removed and imbued into a sword or even directly sent into the human body. It would have been difficult for a human to do the same thing. They would only be confused if they were told to collapse their physical form and enter a sword.
That was what this was.
One could cast off their cage of flesh and ascend the Sephiroth to reach the knowledge there, but that made them more susceptible to external forces. On the other hand, descending the tree placed many different physical restrictions on them, but it gave them a sturdier self. Normal magicians would hate an "unchanging self" as much as a stubborn mind or stiff joints, but it was all in how it was used.
Coronzon had endured.
Need a cite for Index saying this, especially including Magic Gods
> Even ift hey overturned the toy box, could they really find something with equal power to her thatw ould form a pair with her?
[...]
“No.” Index shook her head.
“That isn’t what I mean, Touma. Even if you still had yourr ight hand’s power, that is still something inside the toy box of the world. That does not match Coronzon who is viewing it all from a step removed.”
And a few more quotes about the magical gods being bound to the Surface of the Four Worlds.
wtf Kamachi?
