So I was playing the heroic story for some reason on the moon yesterday. I killed an acolyte to see a purple light fall from his corpse. Primary weapon yes! When I open it though I am greeted by my good friend the ascendant energy. Fortunately it leveled up my cryptarch so I got a legendary engram. Chest engram. I go to open it and I got heart of Praxic Fire!! Am I blessed by RNGesus?!?
