Overview
Adventure Guide says
Imperator Mar'gok assaults players with destructive Arcane magic and summons Arcane Aberrations to fight for him. When Imperator Mar'gok reaches 85%, 55% and 25% health remaining, he activates one of the runestones in his throne room, augmenting his abilities with additional effects. The runestones activated at 55% and 25% must be awakened from their dormant state. As they charge, guards arrive to defend the Imperator as Volatile Anomalies pour from the stone. In Mythic difficulty, Imperator Mar'gok maintains the effects of 2 runestones at once and begins to awake a new runestone at 66% and 33% health remaining.
