Mathematical Analysis of Magicians and DoT Post-Jump

With the way mist explosion scales I can see it reaching the damage cap very easily. From what I've seen on videos you get a 1.5 multiplier on its damage for every DoT more than 1 (on the video he uses PB, FD, mist and Paralyze).

He does about 70k with each hit of paralyze => 70k/2.57 = 27237
He does about 700k with each hit of Mist Explosion => 700k/(9*1.5*1.5*1.5) = 23045

Seems to fit.
