This page covers a healer-focused strategy for the Demonic Inquisition 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.
During this encounter you will be fighting against Atrigan and Belac, who share a health pool.
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 Demonic Inquisition, I've separated the events based on Fel Squall as it's one of the more prominent events in the fight.
Based on the Event List, we can assume the following:
Below are the DBM settings I'll be using for the Demonic Inquisition. 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.
