Prototype Pantheon, Healer Guide

Updated 11 months, 4 weeks ago for patch 9.2.7 by Preston. View the change log.

Prototype Pantheon Dungeon Journal ModelThis page covers a healer-focused strategy for Prototype Pantheon 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

Stage One - War and Duty

This stage begins the encounter and ends when Prototype of War or Prototype of Duty reach 50% health.

  • Prototype of War
    • Interrupt Gloom Bolt to prevent the moderate damage dealt to and the healing absorption effect applied to random players.
    • Dispel Runecarver's Deathtouch (magic) in a controlled manner, once the affected player is more than 8-yards away from other players and inside a Bastion's Ward.
    • During Necrotic Ritual:
      • Avoid the expanding pool of Necrosis. Players inside cannot be healed and take moderate damage over time.
      • All Necrotic Ritualists must be killed to end the Necrotic Ritual.
  • Prototype of Duty

Stage Two - Sin and Seed

This stage begins when one of the Prototypes reaches 50% in stage one, and ends when Prototype of Renewal or Prototype of Absolution reaches 50% health.

  • Prototype of Renewal
    • Interrupt Anima Bolt to prevent the moderate damage and light damage over time dealt to random players.
    • Spawns Withering Seeds across the area.
      • Withering Seed
        • Can be healed by players.
        • When healed to full health, Invigorating Bloom heals all players for a small amount and grants a stacking increased healing done effect.
        • If allowed to die, Withering Nova deals moderate damage to all players and light damage over time.
    • Avoid the path of Wild Stampede.
    • On Heroic, avoid the locations of Animastorms as they rotate around.
  • Prototype of Absolution
    • The tanks will be dealing with Wracking Pain, which increases all damage taken by players and Necrotic Ritualists hit.
    • During Hand of Destruction, move as far away from Prototype of Absolution as possible to lower the damage taken.
    • Avoid the paths of Sinful Projection. Players hit gain one stack of Burden of Sin.
    • At the start of the stage, applies one stack of Burden of Sin to all players, dealing light damage over time.

Stage Three - Pantheon of Death

This stage begins when one of the Prototypes reaches 50% in stage two, and ends when the Prototypes are killed.

  • All Prototypes are active during this stage, and use the same abilities as stage one and stage two.
  • On Heroic, when a Prototype is killed, it begins healing with Complete Reconstruction. This effect is interrupted when all Prototypes are killed.

Mythic Differences

Stage One - War and Duty

Stage Two - Sin and Seed


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


  • Runecarver's Deathtouch (dispel, magic) must be dispelled in a controlled manner.
    • (Optional) Bastion's Ward can be tracked to help indicate when players are ready to be dispelled.
  • Gloom Bolt absorbs a large amount of healing and should be healed off quickly.


  • Pinned causes players to need light healing over time.
  • Anima Bolt causes players to need light healing over time.
