This page covers a healer-focused strategy for Helya in the Trial of Valor. 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 is a three-stage fight where you alternate between fighting Helya and her minions.
During this Stage, you're fighting against Helya. This stage ends when Helya reaches 65% health.
This Stage begins when Helya is at 65% health at which point she submerges and you begin fighting several adds. This Stage ends when enough Gripping Tentacles have been defeated.
Stage Three is a combination of Stage One and Stage Two and ends when Helya reaches 0% health.
Below are the DBM settings I'll be using for Helya. 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 Helya on Heroic difficulty. Again, there is no commentary, only game sounds.
