Flaunt your Damage/Equipment Magicians!

The good ole' (.005979 x magic)^2 one. I know it's not 100% accurate, but since it's +/- 3kish damage (as evident by Harrisonized's calculations), I figured it would be fine. Of course mdef isn't factored into it at all, so I knew with a +/- 3k-4kish amount I'd be CLOSE to the cap at Phantoms, while near guaranteed at lower monsters.

When I'm playing around with numbers that close to something I rarely try to get exact; just go over by 5k and you're fine .

Miserable attempt explaining why almost all magic formula becomes unreliable.

You get that effect for exponential equations.
