Temple of Sethraliss, Healer Guide

Updated 10 months, 2 weeks ago for patch 8.3 by Preston. View the change log.

This page covers healer-focused strategies for the Temple of Sethraliss dungeon. 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 as well as Dungeon Journal information. I'll continue to update it as-needed.


Below are guides for the bosses in Shrine of the Storm, including their abilities, healer notes, and addon settings.

Avatar of Sethraliss Dungeon Journal Model Avatar of Sethraliss

During this fight, players will be fighting against various adds while the Heart of Sethraliss is suspended in the center of the room.

  • The Avatar of Sethraliss must be healed to full health to complete the encounter.
    • The Avatar can only be healed in chunks, first to 70%, then to 100%.
    • At each health break point, a new set of Hoodoo Hexers will spawn, halting healing.
  • Hoodoo Hexer
    • Channels Taint on the Avatar of Sethraliss, decreasing the healing it receives.
  • Heart Guardian
    • Applies Heart Attack to the tank, significantly increasing damage taken.
    • When killed, leaves behind an Energy Fragment.
      • Activate these to grant the Heart of Sethraliss Life Force, healing it for an additional amount each time it receives healing.
