Right now you can do it in the 320 version straight from the director.
Basically you go through the strike until you first see Omnigul at the end of the hallway before the final room. You have a Nightstalker tether her in place so she can't run up the hill like normal, and you kill her there forcing her to drop 2 blues that can go up to 365 Light depending on your own Light level. Either use those as infusion fuel or just equip them and keep increasing your Light level until you get higher blues. Generally people either use the Arc or Solar exotic swords to get enough damage to kill her before she can get away. Helps to have either a Warlock or Titan who can super all of the adds around her to create enough orbs to get everyone's super back by the time she is dead. After that you intentionally wipe (don't go up the hill) and you're back at the checkpoint where she's at the end of the hall again. Rinse and repeat.
