[A/N: finally came to the conclusion of how Arthur's flaw works. Before it was of course the insanity but with like a time limit unless he uses more destruction.
However I see destruction in this fanfic as like another person trying to take over Arthur's body a corrupted version of him if you will, so the flaw is now buffed(shiiii).
Now it's like this, once Arthur uses enough destruction he will of course start going mad, but it will only stop after a certain amount of time without using destruction, however for him to not use Destruction in his insane state there cannot and I mean cannot be a single living beeing near him. Then he will start to calm down. Or he has to pass out for a bit even a second and he will come back to his senses.
It's hard to explain but yeah thought you guys should understand how I see it, since it will affect the story a lot.
Please do ask any questions if you are confused.
Today should be a chapter or a longer one tomorrow, since I'm doing a lot better.]
Thanks for reading.
