How the run goes

One boss under Wyrmrest Temple: Sartharion and his three twilight drakes, Tenebron, Shadron and Vesperon. Killing the drakes first makes Sartharion easier; leaving them alive makes the fight much harder and the rewards better.

Group: Ten or twenty-five players: two tanks (more for drakes-up attempts), healers for the lava waves and the twilight portals, damage dealers.

    • Flame BreathInflicts 8750 to 11250 Fire damage to enemies in a cone in front of the caster.
    • Tail LashA sweeping tail strike hits all enemies behind the caster, inflicting 3063 to 3937 damage and stunning them for 2 sec.
    • CleaveInflicts 35% weapon damage to an enemy and its nearest allies, affecting up to 10 targets.
    • Will of SartharionSartharion's presence bolsters the resolve of the Twilight Drakes, increasing their total health by 25%. This effect also increases Sartharion's health by 25%.
    • BerserkIncreases the caster's attack speed by 150% and all damage it deals by 500% for 5 min.

    Sartharion breathes fire, rains lava and sends walls of lava across the platform. Each of his three drakes left alive joins the fight and opens a twilight portal, which makes it much harder.

    Tanks
    Face him away from the raid for Flame Breath; with drakes alive, a tank for each drake.
    Healers
    Heal through Lava Strike and the lava walls; with drakes up, send healers into the twilight realm with the players there.
    Damage dealers
    Watch for the lava wave and move to the safe side; kill the drakes first for the normal fight.

Before you go

  • Run from the lava waves through the gaps in the wall of fire.
  • Kill the drakes first for a simpler fight, or leave them alive for hard mode.
  • Level 80, no attunement.
