• Binding Shadows – Erudax launches a mass of Binding Shadows at the location of a random player. When the shadows reach the targeted location, the shadows drain 7800 to 8200 life every 1 second and immobilize every player within 8 yards of the targeted location. Erudax heals for three times the amount of life drained by the shadows.
• Enfeebling Blow – Erudax lashes out with an enfeebling blow, inflicting 75% of normal melee damage, the Feeble Body effect, and massively knocking back his current target.

  • Feeble Body – The target of Enfeebling Blow is inflicted with Feeble Body, increasing the damage the player takes by 200% for 3 sec.
• Shadow Gale – Erudax begins to gather shadows at a random location within his room, and then 5 seconds later that location becomes the eye of the Shadow Gale. Erudax channels the storm for 10 sec., and damage dealt to Erudax while channeling is increased by 100%. Players located within the eye of the storm take no damage, but the storm inflicts 9750 to 10250 Shadow damage every 1 second and increases their Shadow damage taken by 50% for 3 sec. The chaotic energy of the storm also increases the movement speed of players outside the eye by 50%.
• Faceless Corruptor – After Erudax completes his channeling of the Shadow Gale, a Faceless Corrupter rushes into the room from the room's entrance hallway. The Faceless Corrupter ignores the players, moves to either the right or left side of the room, and begins to channel Twilight Corruption on one of Alexstrasza's Eggs.If the Faceless Corruptor successfully corrupts an egg, then two Twilight Hatchlings emerge from the egg and the Corruptor begins to attack the players.

  In Heroic Difficulty two Faceless Corrupters enter the room instead of one.

  • Twilight Corruption – The Faceless Corruptor channels onto one of Alexstrasza's Eggs, draining 18% of the eggs life every 1 second for 10 sec. If the egg reaches zero remaining life, the egg hatches and two Twilight Hatchlings fly up into the air.

    • Alexstrasza's Egg – Faceless Corruptors channel Twilight Corruption on Alexstrasza's Eggs to create Twilight Hatchlings.
    • Twilight Hatchling – These newly created hatchlings periodically cast Twilight Blast on players.

      • Twilight Blast – A Twilight Hatchling blasts a random player below for 9750 to 10250 Shadow damage.

  • Siphon Essence – After a Faceless Corruptor successfully corrupts an egg, it will cast Siphon Essence on a random player and drain 14625 to 15375 life every 1 second for 4 sec. The Faceless Corruptor heals for three times the amount of damage dealt.
• Shield of Nightmares – Erudax shrouds all nearby Faceless Corruptors with the essence of nightmares for 4 sec. Any player that attacks or casts a harmful spell on a shrouded Faceless Corruptor causes the nightmares to manifest and immediately inflict 19500 to 20500 Shadow damage on every player.
