This page covers a healer-focused strategy for M'uru 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

Stage One - Minions of M'uru

This stage begins the encounter and ends when M'uru is killed.

    • Shadowsword Berserker
      • The tanks will be dealing with extra damage while Flurry is active.
    • Shadowsword Mage
      • When possible, interrupt Fel Fireball to prevent the light damage dealt to random players.

  • Void waves occur every 30-seconds and consist of one Void Sentinel and four Void Spawns.

This stage begins when M'uru is killed, and becomes Entropius, and ends when Entropius is killed.

Healing Notes

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

  • while Void Spawns are alive if they're near players
  • during stage two
• Other things to watch for
  • Healing increase quickly during stage two, so conserving mana during stage one may be necessary.
