I recently bought an exotic engram from Xûr, and received the Heart Of Praxic Fire. I have heard a lot about how good this chest is, and how rare, so I decided to make a warlock instead of just dismantling the chest piece. Problem is, I don't know anything about warlocks! Does anybody have any ideas for Sunsinger builds to go along with the chest piece? I primarily play pve, but I also play my fair share of crucible. Any suggestions are appreciated!
