Sucks that we would have to do them again just to get the emblem as opposed to ok the character has the mark/bond/cloak give them the emblem. Had already finished my hunter subclasses and warlock sunsinger and turned them in so lost those emblems for now, but I'm completing the rest and waiting till Tuesday to turn the others in. One less thing to do so I can get into the new stuff. Word of advice, the nerf to orbs really blows for nova bomb so as others have said do omnigul and go to the three yellow hive in the tunnel where you spawn for patrol and get the 7 orbs there. I've bombed groups of 6-8 acolytes and thrall and only max at six since they are all red bar. Was using obsidian mind and bad juju to get the super up quick. Also the ward of dawn one seems screwed up, didn't want to register kills in the bubble for me if I shot or punched enemies. Drop the bubble on a group and then quickly throw a grenade, should get 5-6 kills if your in a good spot. I did the steppes on cosmodrome and as soon as the fallen came up the stairs to get outside from that spawn below that big square garage looking structure, I dropped it on them right as they came up and killed most if not all in one shot.

7 orb voidwalker quest- easiest way- Undying Mind Strike with Obsidian Mind helmet. Keep your super charged until you reach those massive stairs with the yellow bar Vex, make sure you can hit at least 3, and WHAM, 7 orbs, repeat 3 times. IF you miss and they are all dead, don't panic. When you get to the boss, don't attack it, pray the other 2 players don't kill it. Eventually enemies spawn...what you're waiting for is yellow bar enemies to spawn near the entrance, not the enemies near the teleporter. Blast them for your 7 orbs.
