@KoLA twelve-generation family is even higher than the Archibalds. That's pretty absurdly huge; keep in mind that a generation for magi is longer than it is for normal people because longevity.
Lower either Circuit Quantity or Quality to B.
The Second Magic doesn't violate conservation of energy, just as an FYI.
If you want to store energy in things, you need a Conversion attribute like the Edefelts. The problem is that if you want to pump energy into gold or something, you can't just lock it in place; it'll naturally seep out because that's how the world works. You can use magical energy, but you need a Conversion attribute for that, and jewels are just better for that anyway, so that basically makes you Rin-Lite.
Also, keep in mind that an A rank attack is enough to destroy a small house; the amount of energy you're describing her as being able to use is way too much, and way, way, way too fast. As an example, a kilogram of TNT is more than a kilowatt hour of electricity; you're not getting that stuff "instantaneously". Forget Rin-Lite, this is closer to Rin-EX.
Being an Average One doesn't mean you can deal with any kind of energy, it just means you can use any of the Five Great Elements. Like, there's not "water prana" and "wind prana", it's all just prana that you filter and then pump into a magic foundation so the World will cast a cool spell.
What aspects of the Mercury Moeblob were incorporated? I don't really understand what the point of it is or what makes it special in general.
