So to start off u will need a noobie or someone who is starting out or anyone who can do the begining quest. Reason why is because if they are doing the GUARDIAN QUEST from shaw Han everytime they go to skywatch a bunch of ORANGE KNIGHTS will spawn. All u need to do is stand on top of the building where u spawn in skywatch and kill the KNIGHT below the building to the right, kill the KNIGHT on the left of building and then a 3rd KNIGHT will spawn beside u on the left again. If u kill them over and over they drop a ton of engrams after about 2 minutes or so.it took me 20 minutes to get all engrams. The great thing about this method is u can farm them non stop as long as your buddy doesn't ho and activate the 3 crystals on the other side of the map. It was sooo easy doing this method instead of all the others. Hope this helps u guys cheers 👍
