There is an Ultra on the Dreadnaught. The one you have to use the terminals to open the doors with. Then when you kill him he will give you an emblem the first time. You can actually just hop over the door. Look it up on YouTube. Anyways. I kill him. He takes 15 minutes to respawn. So I do some shit. Fly back and kill him again. I got 3 from him this morning. 1 from a strike. Lastly. My luck was just good this morning. Last night I ran the raid on my Warlock. First time through on that character. I got no loot until Daughters. Then I got Warlock bond. Killed Oryx and I got two Hand Cannons and another Warlock bond. I've learned to stop expecting anything from this game and just roll with it. Less disappointments.
