This page covers a healer-focused strategy for Gul'dan 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.
Gul'dan is a three stage fight where Gul'dan gets progressively powerful over each stage.
During this Stage, Gul'dan is hidden inside the Eye of Aman'thul and you fight his Lieutenants instead.
With his lieutenants defeated, Gul'dan joins the fight. At 85%, 70%, and 55% health he will empower his abilities, as noted below.
At 40% health, Gul'dan harnesses the full power from the Essence of Aman'thul.
On Mythic, the fight essentially starts in Stage Two from Heroic, with Gul'dan already in the fight.
This fight has a lot going on, but the healing needed is predictable.
Below are the DBM settings I'll be using for Gul'dan. 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 Elisande on Heroic difficulty. There is no commentary, only game sounds.
