Aeonus's portal does not produce adds, and his arrival is signaled by a distinctive shout. All party members should avoid his angle of approach while resting to full health and mana, if combat permits. Provided that few mobs remain from the previous waves, Aeonus drains Medivh very slowly, and it is possible to recover from a wipe with ~50% shield left.
Positioning is not important in this fight as long as the tank is the sole person within the forward cone of the Sand Breath and aggro is held.
Aeonus stuns the party at irregular times and does not stop attacking. Keeping the tank near full health is your only concern. Healers with HOTs should refresh them frequently. While learning the fight, use your fastest spells. An off-healer and mana regeneration effects (e.g. Innervate) are strongly recommended.
Equip: Increases spell power by 37. Equip: Your direct healing and heal over time spells have a chance to increase your spell haste rating by 320 for 6 secs.
The time has come to shatter this clockwork universe forever! Let us no longer be slaves of the hourglass! I warn you: those who do not embrace the greater path shall become victims of its passing! (It is worth noting that this quote was partially stolen from Medivh...)
