its called running it by yourself in your own room with "Auto-join" open and attacking the boss while people join. you will get a 100% kill bonus for that part since you were the only one to attack there and also the bonus for the number of members in the lobby. I got a doom ring about once every two runs. sometimes one for each of my runs.
