Harbinger Skyriss is one of the qiraji entities that the naaru kept locked up within the Arcatraz. He is a servant of the Old Gods and seeks to usher in his masters' vision of conquering all of the worlds in the universe.[1] His plans were surprisingly rewarded when he was picked up by the naaru. He must have corrupted Warden Mellichar into releasing all the prisoners in the Arcatraz.

Skyriss uses the same model as The Prophet Skeram, and appears as the 4th and final mob of a multi wave encounter in the Arcatraz wing of Tempest Keep. The encounter is begun by engaging Warden Mellichar. The warden will in turn open the four orbs along the walls of the room, and finally wake up Skyriss. There are two different varieties of each mini-boss. If the mini-bosses are killed quick enough, there's time for regeneration out of combat between them. The encounter can be reset by running out, after a certain wait time Mellichar will respawn, just like after a wipe.

Many of the mini-bosses, as well as Skyriss himself, are based on classic World of Warcraft raid bosses.

Note: The encounter is not able to be reset if you wipe after Harbinger Skyriss appears but before he becomes attackable (this can happen if a party wipes on the final orb mini-boss). An instance reset is required to reset the encounter if this occurs.

Adventure Guide

The naaru believed the persuasive voice of Harbinger Skyriss was silenced when they contained him and forced him into a long, dreamless sleep. The unfortunate warden of Arcatraz learned the naaru were wrong. Skyriss had just enough energy to speak to Warden Mellichar in a still, small voice. Time took care of the rest.


First Prison Cell

When Warden Mellichar enters combat, he opens the first prison cell, releasing either a Blazing Trickster or a Phase-Hunter.

Skyriss behaves much like The Prophet Skeram from the Temple of Ahn'Qiraj. The clones have less hitpoints and a somewhat reduced set of abilities. They have a normal non-stunning Mind Flay which deals less damage than the original, however if Skyriss and the clone both use their flay/rend on the same person that person will most likely die.

Healing is the key to this fight. Secondary healers should wear their best healer outfit. The job of the backup healer is to keep Millhouse alive, and to make sure the main healer survives when he's affected by the mind flay.

How to deal with Skyriss' abilities:

1. Skyriss clones

  • Be sure that the party leader places a raid icon on the original boss so the copies are easily identified and killed ASAP

2. Random Target Mind Rend

  • This deals a total of 3750 damage. This attack hits for a total of 4800 in Heroic. If the healer is hit, an off-healer can be a great help.

3. Mind Control

Shadow Protection buff is helpful to resist or break the MC early as well as the mindflay.

A warlocks Felhunter pet can use "Devour Magic" on fears/mind rends/mind control debuffs.

Mages can blink or ice block out of the mind flay, minimizing the damage they take.

A Rogue in melee range will attract every fear and many mind controls; conscientious rogues will equip their PvP trinket and use it early in the fight to absorb as much CC as they can. Bear in mind that [Cloak of Shadows] can be used by Skyriss while you are Mind Controlled, and break the effect early.

Hunters - make sure to get a Snake Trap out, Skyriss will Mind Flay the snakes, saving you a few Mind Flays and making it easier on your healer.
