I strolled by the Court of Oryx last week, just to see if anything was going on and if I could get my Tier 3 done (I still needed to kill Kagoor for the grimoire/calcified fragment). There was one guy there. So we ran a couple reciprocals and then a couple stolen runes. I then figured screw it and threw in my antiquated rune. I pulled out Black Spindle and we cut through the ogres like hot knives through butter. I then tethered Kagoor and went in for the kill with my HMG. We got her about two-thirds dead and then I died suddenly from all the thralls that I didn't realize were right behind me. I was thinking "I hope random dude revives me before her shield comes back". All of a sudden I get the Chest Unlocked message on-screen, grimoire cards are popping and my "Tier 3 opponents in less than two minutes" bounty was completed. Dude polished her off all by himself. I gave him a wave, we had a dance and then he went on his merry way. I was totally prepared to return the favour and help him complete his own antiquated rune but apparently he was just there to help whoever needed it. Thanks dude!
