Loatheb, Healer Guide

Updated 9 months, 4 weeks ago for patch 1.13.6 and Season of Mastery by Preston. View the change log.

Loatheb Dungeon Journal ModelThis page covers a healer-focused strategy for Loatheb in Naxxramas. 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, logs information, and Dungeon Journal information. I'll continue to update it as-needed.

General Mechanics and Abilities

  • Applies Corrupted Mind to all players for the duration of the encounter, allowing only one healing or dispelling spell to be cast every 60-seconds.
  • Stay more than 10-yards away to avoid Deathbloom (dispel, poison).
  • Persistently removes all curse effects from itself with Remove Curse.
  • Spawns Spores frequently throughout the encounter.
    • Spore
      • Upon death, up to 5 players within 10-yards gain Fungal Bloom, greatly increasing spell and melee critical strike chance and stopping threat generation.
  • After 2-minutes in combat, deals moderate damage to all players every 30-seconds with Inevitable Doom.
    • After 5-minutes in combat, this increases to every 15-seconds.

Season of Mastery Differences

  • Currently, I'm not aware of any mechanical differences.
  • There are new quests offered by Archmage Tarsis Kir-Moldir just inside Naxxramas, and it was suggested that these could lead to surprises that "have a significant impact" inside and outside Naxxramas.

Resistance Levels

  • Players generally won't make use of any additional resistances on this encounter.

Healing Notes

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.

  • This encounter forces all healing activity to be very well calculated because of Corrupted Mind. Chances are you'll want to setup a rotation for healing the tanks while leaving DPS to use their own healing items and abilities to keep themselves alive.
  • Helping DPS the boss will also be required, especially while you're healing spells are on cooldown.
