Chromaggus, Healer Guide

Posted 1 year, 8 months ago for patch 1.13 by Preston.

Chromaggus Dungeon Journal ModelThis page covers a healer-focused strategy for Chromaggus in Blackwing Lair. 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

  • Breath Attacks
    • Two out of the five breaths will be used with each raid reset, chosen at random.
    • The breaths hit all players in line of sight of Chromaggus and all players but the tank should break line of sight to avoid their effects.
    • Breaths
      • Incinerate (red) deals heavy damage to all players.
      • Corrosive Acid (green) applies a damage over time effect that deals moderate damage over 15-seconds and reduces armor.
      • Frost Burn (blue) deals moderate to all players and applies a reduced attack speed effect.
      • Time Lapse (bronze) stuns all players and reduces maximum health by 50% for 6-seconds.
      • Ignite Flesh (black) applies a stacking damage over time effect.
  • Brood Afflictions
    • Applies random Afflictions to all players, regardless of if they're in line of sight of Chromaggus or not.
    • If a player has all five Afflictions at once they are transformed into a Chromatic Drakonid.
    • Afflictions
  • Periodically Shimmers, gaining increased resistance to and increased vulnerability to different schools of magic.
  • Frenzy should be dispelled with Tranquilizing Shot to remove the increased attack speed and spell damage effect.

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.

  • Overall priority on this fight is dispelling Afflictions and keeping players with Brood Affliction: Red (dispel, disease) alive until they're dispelled.
  • Brood Affliction: Blue (dispel, magic) should be dispelled from yourself and other healers quickly.
  • Apply as many heal over time or absorption effects to the tank as possible before breaking line of sight for Time Lapse.
