Lets keep this on top so people know... There seems to be alot of confusion about them..heres what im doing, its got me 5 exotic engrams and ive only used around 20-25 coins... the scorge of winter mission on lowest difficulty, on venus, run to the boss at the end. 1 - use 1 coin 2- get his health low 3 - rocket suicde next to him (itll kill both of you) 4 - rinse and repeat Edit 1 .. just got a year 2 monte carlo, so you can get yr 2 exotics from a yr 1 ultra :) ... happy hunting guardians Edit 2.. https://account.xbox.com/en-us/gameclip/5ab3f33e-9b32-41a7-a7fc-a1d0dab34ca0?gamerTag=xBOWLxBREAKERx&scid=03a80100-9ff3-46ea-be76-e00e7fe465df Edit 3.. for all the doubtful guardians.. https://account.xbox.com/en-us/gameclip/49824c36-033e-4538-ac38-f9f7e46ea3c1?gamerTag=xBOWLxBREAKERx&scid=03a80100-9ff3-46ea-be76-e00e7fe465df Edit 4.. as of 210 est.. it is still working. Edit 5.. it wont drop everytime u kill the boss, it might take up to 15 or even 20 tries sometimes, and other time it could only take a few... just be patient
