Lihuvim, Healer Guide

Updated 1 year ago for patch 9.2.7 by Preston. View the change log.

Lihuvim Dungeon Journal ModelThis page covers a healer-focused strategy for Lihuvim, Principal Architect in Sepulcher of the First Ones 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 with the encounter, combat log information, and Dungeon Journal information. I'll continue to update it as-needed.

General Mechanics and Abilities

Normal and Heroic

  • On Heroic, stay more than 12-yards away from the tanks to avoid Resonance, which causes alternating blasts of Kinetic Resonance and Sundering Resonance.
  • During Manifest Mote, when targeted by Unstable Mote move as far away from other players as possible to drop the resulting Unstable Mote.
    • Unstable Mote
      • Standing near an Unstable Mote expands its Unstable Mote pool, dealing moderate damage over time to all players inside it.
  • When affected by Deconstructing Energy, stand within 8-yards of Unstable Motes to deconstruct them with the resulting Deconstructing Blast.
    • Affected players take light damage over time and then moderate damage, and then take greatly increased Physical damage.
  • At 100% Energy, during Synthesize:
    • Synthesized Automa begin forming inside construction bays. One of these can be killed before fully forming.
      • Degeneration Automa
        • Stun to interrupt Degenerate to prevent the moderate damage over time dealt to random players.
      • Acquisitions Automa
        • Deals increasing light to moderate damage to all players with Instability.
        • Upon death, stay more than 20-yards away to avoid Detonation.
      • Guardian Automa
      • On Heroic, Defense Matrix Automa
      • Standing inside a construction bay grants Protoform Disalignment, greatly reducing Cosmic damage taken while removing stacks of Protoform Radiance, detailed below.
    • Deals increasing moderate to heavy damage over time to all players with Protoform Radiance.
  • Avoid the impact locations of Protoform Cascade.
  • Deals moderate damage to all players and knocks them back with Cosmic Shift.

Mythic Differences


Healing Notes

Quick Notes, All Difficulties

The notes below mostly pertain to progression difficulty, meaning if you out-gear the difficulty you're on or use extra healers they may not apply.

Debuffs to Track



  • Unstable Mote causes players to need light healing.
  • Degenerate causes players to need moderate healing over time.
