Hey so, I ran it and got it today, I ran it with 2 other friends who didnt have the time trial either the( honed edge ) one, so we thought we would experiment with it to see what unlocks it. 1st run, killed all adds, sword was placed/ dropped once due to member popping a rift. No deaths in fireteam, sword ran all the way through the end portal after collecting chest. 2:16. No triumph. 2nd run, didnt kill all adds, sword dropped twice, no deaths, sword ran through portal and chest collected. 3:41. No triumph 3rd run, killed all adds, 1 death, one sword drop, chest collected and sword ran through portal, 2.56. No triumph 4th run, killed all adds, did not drop sword, 2 deaths (same guy), chest collected only by the 2 guys who were ahead, sword ran through portal, 3:18. Triump awarded to the members who claimed the chest and went through portal. 5th run to get the triump for the last guy. [i][b]Did not kill all adds. 1 death, waited for member to catch up. Sword was not dropped at all All 3 members collected chest. Sword was run through the portal. 3:13 Triump awarded[/i][/b]. Now, having done the other time trial last week, cant remember the name of it. 3 of us went in 1 dude rushed ahead and cleared the boss and grabbed the chest before we all got to it. (Didnt leave through portal) but gave us all the triumph Keeper of honed edges however seems to be really specific to a degree for awarding the triump, dont drop sword, make sure you collected the chest (everyone that still needs the triumph) leave portal with sword under around 3:30. If that still doesnt work for you, well then im sorry to hear that but thats all i was able to gather with my friends.

I've got the same problem. Been trying all week in multiple characters with no success.
