Here is how i did it: get a f8reteam of 3, start up devils lair, the one who needs to create the orbs (you) goes back to the where you spawn at patrol, get your super and use it on the hive majors that spawn to the left of the patrol spawn (there is a little house with stairs to go downstairs, there will spawn 2 major acolyte and a major knight) do that 3 times and get back to your fireteam You need to be in a strike to do the 7 orbs thing, but not in a respawn restricted area
