White orbs should be intercepted at range before getting to the boss.
Boss gains a shield at 100% energy, which has to be dps'd down.
The shield causes raidwide damage and sucks players and orbs towards it.
Tanks are targeted with Lightshatter Beam. Causes damage and debuff. Raiders avoid. Tanks taunt swap after each beam.
Giant yellow circles target raiders. Spread out, then move after missile hits, to find a safe spot.
Raiders will get a dispellable debuff that does ramping damage and a ramping slow. Dispel (on heroic, dispel in path of white orb).
at 80% and 50% health boss will move to new location, doing raid wide damage. Follow. Healers be aware of incoming damage.
Whilst moving to a new location, raiders will need to run ahead to break golden orbs, otherwise they may end up knocked back and locked out of the next location.
Use Bloodlust in third room. Soft enrage as damage ramps up and orbs speed up.
