[1.2.253] Attack Belt

Uh, have you ever used Dragon Roar?

Nope.

 magical damage

x is the magic attack, the spell has 140 basic attack. I figured INT = 4/5 of the magic attack.
MAX = (((x^2)/1000+x)/30+(.8x)/200) *140
MIN = (((x^2)/1000 + x *0.54)/30 + (0.8x)/200)*140
Ignore the line in the top middle, my computer doesn't like blank images so I used a filler.

So yeah. It's quadratic, but pretty close to being linear. I sorta wish that I could show you a graph of other classes' damage, but it'd be 3d (4d if you count the secondary stat).
