I counted the Holy Talent that increases damage, actually.
No, I didn’t, buddy. Learn to read.
1.31.
15% from Shadow form.
10% from Darkness.
6% from Shadow Weaving.
3% comes from SW:P application. Another 3% from starting to channel Mindflay.
That only increases your spell power, buddy. Do you even know how your class works?
Well, your crit chance is going to vary, but I can account for the talents, at least.
100 spell power.
100 * .5999 = 60
100 * .2665 = 27
246 direct damage on average.
5% crit from Holy Specialization
(246 + 60) * 1.05 = 321
85 DoT damage
85 + 27 = 112
321 + 112 = 433
433 * 1.1 = 476 / 170 = 2.8 DPM
Sorry, but even accounting for the crit, the DPM is lower.
Fixed it for you.
Still lower DPM, by the way.
