The Underrot, Healer Guide

Updated 2 weeks, 2 days ago for patch 8.0 by Preston. View the change log.

This page covers healer-focused strategies for The Underrot 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 The Underrot, including their abilities, healer notes, and addon settings.

Elder Leaxa Dungeon Journal Model Elder Leaxa

 Healing Notes

  • Use Cooldowns when Blood Effigies are active.
  • Watch for players with high stacks of Taint of G'huun.

Cragmaw the Infested Dungeon Journal Model Cragmaw the Infested

  • Infested causes Cragmaw's abilities to spawn Blood Tick Larva.
    • These must be stepped on before their Metamorphosis cast finishes or they'll turn into Blood Ticks.
  • Don't be in front of Cragmaw to avoid Indigestion.
  • Targets random players with Charge, knocking back any players hit.
  • On Heroic, at 100% energy Tantrum deals light damage to all players and spawns Blood Tick Larva randomly around the room.

 Healing Notes

  • Use Cooldowns on Tantrum or if too many Blood Ticks are active..
 Debuffs to Track

Sporecaller Zancha Dungeon Journal Model Sporecaller Zancha

  • Taking damage from any ability will apply a stack of Decaying Spores (dispel, disease).
  • Avoid the Spore Pods created by Boundless Rot.
    • These must be destroyed by players affected by Upheaval or by the tank using Shockwave.
  • At 100% energy, Festering Harvest detonates all Spore Pods, inflicting moderate damage to all players and applying a stack of Decaying Spores for each Spore Pod that was active.
  • On Heroic, Volatile Pods creates additional Spore Pods.
