same goes to me, I got the praxic fire from the trollarch (when legendaries engrams were turned to rare items) I got my first praxic fire there it was like all the luck that I had and the luck that I will have in one drop, then I got another one from a exotic engram, then a nightfall reward, then another legendary engram, I didn't want xur to sell it because I wanted to give my 3 extra praxic fire to 3 different warlocks first but with no trading...
