RNG frequently shafts us all. I'll share a recent win. I noticed Xur was selling Mida and Alpha Lupi, both of which I wanted for my newly leveled Hunter. I only had enough Strange Coins for one. So I gambled on the thought that I could get Alpha Lupi from the Chest Engram Xur had. I bought the Mida for the Hunter and went ahead with the engram. I went to Rahool, and RNG saw fit to drop Alpha Lupi, just as planned. I love it when a plan comes together!
