MOTHER, Healer Guide

Updated 41 minutes ago for patch 8.0 by Preston. View the change log.

MOTHER Dungeon Journal ModelThis page covers a healer-focused strategy for MOTHER in Uldir. 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.

General Mechanics and Abilities

Normal and Heroic

MOTHER only needs to be brought to 10% health to end the encounter.

  • Before the currently occupied chamber reaches 100% energy, players need to move through the Defense Grid to the next chamber.
    • Each player that moves through the Defense Grid deals damage to the group.
      • On Heroic, this also applies a stacking debuff to the entire group that increases their damage taken.
      • Numbers of players that can safely move through at a time: 4-5 on Normal, 3-4 on Heroic, 2-3 on Mythic.
    • Each player that moves through will spawn a Clinging Corruption inside the new chamber.
    • The Defense Grid walls break line of sight, so healing through them isn't possible.
    • At 100% energy, Cleansing Purge is cast inside the chamber.
  • Don't stand in front of the boss to avoid Sanitizing Strike. This ability will prompt a tank switch.
  • Avoid the impact locations of Purifying Flame.
  • During Wind Tunnel, avoid being pushed into the open fire vents at either side of the chamber.
  • Starting in the second chamber, avoid the Uldir Defensive Beam wall that moves across the chamber.
  • Starting in the third, final chamber:

Mythic Differences

  • When passing through the Defense Grid, two new adds will spawn from tanks and healers.
    • Tanks spawn a Resistant Bacterium.
      • Applies a stack of Bacterial Outbreak to the tank, increasing their damage taken from all Embodiment of Containment adds.
    • Healers spawn a Viral Contagion.
      • Applies Endemic Virus to random players.
        • This must be dispelled in a controlled manner when the affected player is at least 10-yards away from other players to prevent Spreading Epidemic from hitting anyone.

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

Major

Minor

  • Sanitizing Strike causes the affected tank to take additional damage.
  • (Optional) Clinging Corruption causes the entire group to take critical damage. Ideally this will never be present.
  • (Optional) Defense Grid causes the entire group to take additional damage depending on the number of stacks.

 DBM Settings

Below are the DBM settings I'll be using for MOTHER. 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.
