Summon Chaos PortalSetesh channels onto a random location in the room, and opens up a Chaos Portal. When the portal opens, two Void Wurms appear. After another 12 seconds a Void Seeker appears, then after 15 seconds a Void sentinel appears. The Chaos Portal then closes. In Heroic Difficulty the Chaos Portal does not automatically close. Players must attack and destroy the portal to stop additional void creatures from entering the fight. When this Chaos Portal opens, a Void Sentinel appears then two Void Wurms appear six seconds later. In another ten seconds a Void Seeker appears. Then every 15 seconds the Chaos Portal is still alive, two Void Wurms or one Void Seeker appears.
