Does everyone know the spellpower coefficient of the "Boom"/Dispel - Effect of Vampiric Touch?
I've founded no answer on wowwiki and everybody says something different..
After doing the math myself, I ended at 140% before adding talents as Darkness, Shadowform and Shadow Weaving. It might not be 100% right, since I cba respecc to a spriest tree without Darkness to see how it affects the tooltip. But if Darkness affects the basedamage on the tooltip, the coefficient would even higher.
