These two dragons are in the final room in VP. Phara Dar is up on the platform and the Shade of Khalan Dar is down on the floor. You will require two tank groups for this fight.
To start the fight just run into the room as a raid. Have the main tank group grab and hold onto Phara Dar while the off tank group and dps groups kill Shade of Khalan Dar. The Shade of Khalan Dar will heal up twice during the fight. Once the Shade of Khalan Dar is dead the raid turns on Phara Dar.
Phara Dar has an uncurable elemental that it will place on the tank. If you heal the tank while this elemental is on them you will instead heal Phara Dar. So the trick is the off tank rescues it immediately when the main tank calls they have it. And when the off tank gets the elemental the main tank will then rescues it off them. The elemental lasts around 45 seconds.
One other thing to note is that both dragons reflect spells. Once the Shade of Khalan Dar is down you will find Phara Dar reflects less.
This is a very easy fight. It updates mythicals for Monk, Ranger, and Shadowknight.
