You don't need to wait for it to be the daily Heroic anymore: you can run it anytime so long as you choose the heroic mode / hard mode. Keep in mind that it's tricky. If you wipe (or die solo) during any darkness zones then you have to restart from scratch. And most of the hard-mode mission is darkness zones. You'll need to find some hidden memory fragments (dead ghosts) all over the place. Again, without dying. There are plenty of videos showing how: I suggest equipping a high-control jump for the first one. Then continue through and beat the normal boss. [b]Then[/b], instead of going to Praedyth's bones to finish the mission, you go to the Jumping Puzzle from the Raid... near the platforms is one more ghost. Getting that ghost will open a Gate which will take you to a secret boss fight. Beat the boss and the Cult Ghost will unlock which you can give to the FWC contact. But the Boss fight is epic... or at least was back during TTK without the high-light RoI gear.
