If you're on Xbox 360 and struggling with this "Imprecation" quest, maybe we could team up to help each other out. Send me a friend request on Xbox Live if interested. I did the first two parts and only need help getting 7 kills in a single Crucible match. If anyone's having problems with the PvE part, I can help you find a good place to complete it. The "First Curse" gun may be rubbish but at least it can be infused to upgrade another good weapon. Let me know. Cheers.
