All of these equations only work for over 100 focus. It seems the dev's combined 2 equations, one for under 100 focus which grows faster (mabye log I haven't figured it out yet) and one equation for over 100 Focus. The equation over 100 focus seems to be a second order polynomial. I hope you are happy with my R^2 values :).

All this data was taken at 690 fire ability and 20 skill points in each skill.

The equations for over 100 focus are as follows: Y is damage and X is focus.

Incinerate (total damage over 20 seconds):

y = -0.0007429x^2 + 0.9437295x + 541.6653104
R² = 0.9996679

Firebolt:

y = -0.0005877x^2 + 0.7416841x + 258.5860696
R² = 0.9999691

Lure of Fire:

y = -0.0003371x^2 + 0.4246321x + 191.6934865
R² = 0.9998995

Also for all non-mathmaticians:

R^2 referrs to how far each point that I plotted was from the equation I gave you. So an R^2 value of 1.000 means that each point was exactly on the line. Since my values were 0.999, it means that each point I plotted was almost exactly on the equation of the line I gave you.

But, If I only had 2 points and found an equation the R^2 would be 1.000 since the two points are both exactly on the line.

This is why it is important to have a high R^2 value AND a lot of points. The spacing between the points doesn't matter. My equations have both a lot of points and a good R^2 value so they are very accurate.

Nice graphs. Dang, now there is another factor that effects damage that I didn't consider, ability. Does anyone know how much damage goes up from ability? Maybe if we are lucky there is a standard factor that we can divide by to get our damage reported abilityless.
