This page covers a healer-focused strategy for The Desolate Host in the Tomb of Sargeras. While it's tailored for healers, other roles may also find the information useful. If you have any suggestions or feedback, you can leave a comment below or tweet @PrestonDvorak.
This guide has been updated and maintained based on my own experiences with the fight as well as Dungeon Journal information. I'll continue to update it as-needed.
This fight takes place across two realms, the Corporeal Realm (living) and the Spirit Realm. Several adds are also present in each realm.
At 30% health, the Engine of Souls releases the Desolate Host. The Desolate Host has several abilities that will be handled differently depending which realm you're in. However, players in both realms are able to see and attack it.
Consider this section in "beta." My goal is to lay out the order of events without necessarily providing an entire strategy for all roles (other sites do that already). The idea being it should help organize your cooldowns or pre-healing. Feedback is greatly appreciated as Tomb of Sargeras is my first time attempting something like this.
The event list lays out major boss abilities based on what time they occurred after the boss entered combat (denoted by [minutes:seconds], along with notes on how to identify or handle the mechanics. Once enough events have repeated to develop patterns, the patterns are noted below the event list. Numbers are based on a 20-man Heroic group.
For The Desolate Host, I've separated the events based on realms. Some information may be a little sparse due to the random nature of which realm I'm in during the fight.
Abilities denoted as "first" may not technically be the first ones of the entire fight, just the first ones I've seen after switching realms. I also wasn't seeing the graphic for Spear of Anguish, I'll add those times as soon as possible.
On Heroic, as long as Soul Queen Dejahna is still alive, the Spirit Realm will still need to deal with Wither, and as long as the Engine of Souls is alive, the Corporeal Realm will need to deal with Spear of Anguish.
Based on the Event List, we can assume the following:
Below are the DBM settings I'll be using for The Desolate Host. You can set them up however you'd like, but these ones should work well as a starting point. Some settings may be Mythic only.
