Felmyst, Healer Guide

Updated 1 week ago for patch 2.5.5 by Preston. View the change log.

Felmyst Dungeon Journal ModelThis page covers a healer-focused strategy for Felmyst in Sunwell Plateau in The Burning Crusade. 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

During this encounter players will be alternating between the two stages.

All Stages

  • Deals light damage over time to all players for the duration of the encounter with Noxious Fumes.
  • After 10-minutes, Enrages, greatly increasing damage dealt.

Stage One - Ground

This stage last for about 60-seconds and begins again following 90-seconds in stage two.

  • The tanks will be dealing with Corrosion, greatly increasing physical damage taken.
  • Don't stand in front to avoid Cleave.
  • Dispel Gas Nova (magic) quickly, starting with healers and mana users.
  • During Encapsulate, move more than 20-yards away from the affected player to avoid the heavy damage over time.

Stage Two - Air

This stage lasts for about 90-seconds and begins again following 60-seconds in stage one.

  • When targeted by Demonic Vapor, run to avoid the beam and resulting poison clouds.
    • This spawns several Unyielding Dead, and will spawn additional if a player touches the cloud.
  • During Fog of Corruption:
    • Avoid the third of the room Felmyst flies over.
    • Players hit by the fog are mind controlled and gain greatly increased damage and healing done.


Resistance Levels

  • All players should use as much Arcane Resistance as possible without sacrificing other stats.

Healing Notes

Quick Notes

The notes below mostly pertain to progression difficulty, meaning if you out-gear the encounter or use extra healers they may not apply.

  • Use Cooldowns
  • Other things to watch for
    • Players will likely be spread out during stage two and some may be out of range of healing.

Debuffs to Track

Major

  • Corrosion can cause the tanks to need additional healing.
  • Gas Nova (dispel, magic) should be dispelled immediately.
