Opening the Dark Portal, Healer Guide

Updated 3 weeks ago for patch 2.5.1 by Preston. View the change log.

This page covers healer-focused strategies for the Opening the Dark Portal dungeon 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 as well as Dungeon Journal and combat log information. I'll continue to update it as-needed.

The overall goal of this dungeon is to prevent the enemies and bosses from destroying Medivh's shield. Medivh is located near the back of the dungeon by the Dark Portal. All enemies and bosses will attempt to attack him until damaged by a player.

 Trash Mobs

Below are notes for the trash mobs in Opening the Dark Portal. Opening the Dark Portal is a wide open dungeon, however, you're kept in a smaller area due to all trash mobs and bosses coming from random portals near the Dark Portal itself. Due to this setup, any of the trash mobs noted below can come from any portal.

  • The following enemies are scattered around the dungeon and don't come from the portals.
    • Blackfang Tarantula
      • Dispel Ebon Poison (poison) to remove the reduced healing received effect.
    • Sable Jaguar
      • Are initially invisible due to Sneak.
  • One of the following enemies emerges as the mini-boss of each portal that opens (if it's not a boss portal). Defeating them closes the associated portal.
    • Rift Lord
    • Rift Keeper
      • Stay at least 10-yards away to avoid Blast Wave.
      • Interrupt Pyroblast to prevent the moderate damage and light damage dealt over time.
      • Interrupt Shadow Bolt Volley to prevent the moderate damage dealt to all players.
      • Interrupt or dispel Polymorph (magic) to remove the incapacitating effect.
      • Interrupt or dispel Fear (magic) to remove the fear effect.
      • Dispel Curse of Vulnerability (curse) to remove the increased magic damage take effect.
      • Soothe Enrage to remove the increased attack speed and physical damage dealt effect.
  • The following enemies will periodically spawn from any active portal, and are generally weaker.
    • Infinite Assassin
      • The tank will be dealing with the stun from Kidney Shot, possibly leading to a temporary threat drop.
