I don't know any off the top of my head so I'll write a
very basic outline for you here.
- Pre-cast Army 5 secs before pull
- Use Apocalypse when you have 8 stacks of Festering Wounds
- Keep Virulent Plague up 100% of the time using Outbreak
- Keep Festering Wounds above 4 stacks once you have Scourge of Worlds artifact trait
- Pop wounds using Scourge Strike/Clawing Shadows
- Use Ebon Gargoyle/Dark Arbiter to line up with trinket procs/bloodlust
- Use Dark Transformation on CD or delay slightly (no more than ~15secs) for AOE
- Consume Runic Power using Death Coil
For AOE:
- Apply Outbreak when the group is stacked up
- Use 3x Epidemic charges if taken
- Place Death and Decay and begin to spam Scourge Strike/Clawing Shadows, as it turns into AOE within DnD. You have to be standing within DnD in order for SS/CS to cleave - the adds don't necessarily have to.
There's some more depth to it outside of this, specifically with wounds and pooling RP when taking Dark Arbiter, but this is the general, basic outline. Note that in some builds this hasn't always been the case - at one point it was a DPS gain to completely ignore Festering Wounds. However, it is apparent that the list I've given is the way Blizzard intend the class to be played, and as of writing this (Beta Build 22231) list is correct.
