De Other Side, Healer Guide

Posted 1 month ago for patch 9.0 by Preston.

This page covers healer-focused strategies for De Other Side dungeon in Shadowlands. 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 and combat log information. I'll continue to update it as-needed.


Below are guides for the bosses in De Other Side, including their abilities, healer notes, and addon settings.

Hakkar the Soulflayer Dungeon Journal Model Hakkar the Soulflayer

  • The tank will be dealing with Piercing Bard.
  • Blood Barrier deals moderate damage to all players and Sons of Hakkar, granting Hakkar a damage absorption shield equal to the damage dealt and making him immune to interrupts while the shield is active.
    • Avoid the impact locations of Blood Barrage and interrupt the channeled cast as soon as the damage absorption shield is depleted.
  • Stay at least 7-yards away from other players to prevent the spread of Corrupted Blood.
  • Son of Hakkar will periodically join the encounter.
    • Son of Hakkar
      • Deal steadily increasing damage to all players with Blood Nova.
      • Upon death, avoid the Spilled Essence pool.
        • The pool gradually shrinks while healing the Son of Hakkar that spawned it. The Son of Hakkar will become active again at full health.
          • On Mythic, the pool no longer shrinks.
      • On Mythic, fixate on random players with Zealous.
