Sartharion, Healer Guide

Updated 8 months ago for patch 3.4.1 by Preston. View the change log.

Sartharion Dungeon Journal ModelThis page covers a healer-focused strategy for Sartharion in The Obsidian Sanctum in Wrath of the Lich King. 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.


Sartharion ModelGeneral Mechanics and Abilities

Lesser Drake Mini-Bosses

Prior to engaging Sartharion, players can kill up to three mini-bosses located around the outside of the central area to reduce the overall difficultly of the Sartharion encounter.

  • Shared Abilities
    • Don't stand in front to avoid Shadow Breath.
    • Avoid the locations of Shadow Fissures, which deal moderate damage to any players inside them with Void Blast.
    • Each Lesser Drake has a different effect to deal with as their Twilight Shift ability, noted below. The following effects are consistent for each Drake.
      • Players inside the Twilight Realm deal reduced damage and take moderate damage over time from Twilight Shift.
      • Upon leaving the realm, players are temporarily immune to Shadow damage due to Twilight Residue.
      • One tank and healer should remain outside the Twilight Realm to continue handling the Drake.
  • Tenebron
    • During Twilight Shift:
      • Occurs about every 30-seconds.
      • Players can enter the Twilight Realm to kill Sartharion Twilight Eggs before they're hatched with Hatch Eggs.
      • Alternatively, players can wait for the Eggs to hatch and the Sartharion Twilight Whelps to emerge from the Twilight Realm.
        • Sartharion Twilight Whelp
          • The tanks will be dealing with Fade Armor, reducing Armor.

      • Occurs about every 30-seconds.
      • Players must enter the Twilight Realm to kill the Acolyte of Vesperon to remove Twilight Torment from Vesperon.
        • While active, Twilight Torment deals light to moderate damage to attacking players.

  • Don't stand behind to avoid Tail Lash.

      • If it's hit by a Flame Tsunami, soothe Molten Fury to remove the greatly increased health and damage dealt effect.

Sartharion ModelHealing Notes

Quick Notes, All Difficulties

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.

  • Use Cooldowns
  • Pre-heal Before (mainly for heal over time classes)
    • Lesser Drakes: entering the Twilight Realm
  • Other things to watch for
    •  There can be periods with a lot of movement, so keeping players near full health and heal over time effects on the tanks can be beneficial.

Sartharion ModelDebuffs to Track


  • Fade Armor can cause the tanks to need additional healing.
  • Flame Tsunami causes players to need moderate healing over time.
