Tip #1 pray to RNJesus (the RNG religious figure) Tip #2 grind bounties to get your vanguard/crucible up to rank 2 so you can have a "steady" supply of shards.(via breaking down legendary gear) Tip #3 use shards from tip 2 to upgrade the many items you get from faith in RNJesus at the VOG. Tip #4 do treasure chest runs. RNJesus gave me a rare ship out of one and engrams help rank up the cryptarch. (Won't help with light unless the cryptarch engram package you get from leveling him up is purple and happens to not be a gun. Remember - in RNJesus we trust.
