Unholy Death Knight Frequently Asked Questions — The War Within Pre-Patch
On this page, we go over several of the most frequently asked questions regarding Unholy Death Knight in World of Warcraft — The War Within Pre-Patch. This will be updated as more common repeated questions surface over the course of the expansion.
How do I use the Legendary?
Use after your first 
Festering Strike in Single Target and then on
CD afterwards (not overlapping other CDs). Use
at the end of pulls in Mythic+
How should Soul Reaper be used in the rotation when you hit 35% on the target?
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!
When does the strict Mastery diminishing return hit?
At 68.4% Mastery.
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.
Is the Disease build viable in Mythic+?
Yes, it is the go-to build everywhere.
Do I need a specific amount of Haste?
There are not any real breakpoints to aim for, generally get as much Haste as you can for single target (raw amount less than Mastery), but also trust your simulations!
