This page covers a healer-focused strategy for Krosus in The Nighthold. 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.
According to the Dungeon Journal, there are no ability or mechanical differences on Mythic difficulty.
Healing this fight should be very easy, it has relatively low damage and very predictable damage spikes.
Below are the DBM settings I'll be using for Krosus. 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.
Below is a video of me and my guild defeating Krosus on Heroic difficulty. There is no commentary, only game sounds.
