How should Soul Reaper be used in the rotation when you hit 35% on the target?

Soul Reaper Icon Soul Reaper should be used off cooldown if the target's health is 35% or below. You can also use Soul Reaper before the target hits 35%, as long as the target will be 35% or below when the Soul Reaper debuff expires. It is important to save a Rune for Soul Reaper so that you can use it as soon as it comes off cooldown!


How does the buff from Frenzied Monstrosity work?

Frenzied Monstrosity Icon Frenzied Monstrosity applies both a buff to you and your pet. The buff applied to you always lasts 15 seconds and cannot be extended. The buff on your pet lasts as long as Dark Transformation Icon Dark Transformation lasts, meaning it can be extended.


When does the strict Mastery diminishing return hit?

At 68.4% Mastery; that is 1050 rating.


Do I need to play around procs of Runic Corruption?

No. The procs stack on top of each other. Any remaining duration is simply added to the new one if you get another proc.


How does the stat proc off Inscrutable Quantum Device work?

During Bloodlust Icon Bloodlust/Heroism Icon Heroism, your highest stat by raw rating is chosen and the duration is increased to 25 seconds. Outside of Bloodlust/Heroism, one of your top 2 stats (by raw amount) is chosen randomly.
