They just don't ever seem to drop. Are these super rare and I just need to keep at it? Or am I doing something wrong? Do they only drop when the trial is done normally, level synced with a group?

Thank you in advance to all replies.

There's a player in my Marilith FC that had managed to collect the entire set last year so it sounds like RNG is holding out on you. All I can suggest is to keep trying and hopefully they drop soon.

I got the whole set in less than an hour soloing on my lala. Didn’t count how many runs it took as the thing dies in about 10 seconds and I was just requing immediately.

Rydio,

I ran that tonight and it took 11 runs to get the entire set - don't know if I'm extremely lucky, you have had extremely bad luck or a bit of both. Each run took 10 to 15 seconds.

We're on the same server - would be happy to help you out and get your last two pieces. HMU anytime mate - Jareck Atessa on Sarg

*spends 30 sec a day with a task*
*complains that he didnt finish it within a total of 10 mins*

you cant make this up anymore..

So, I have come to the conclusion that RNG was, indeed, holding out on me.

I kept running the Trial a few times every other night and then on Friday, the last two pieces I needed dropped, one right after the other...

I appreciate all the replies, suggestions and offers of help! My Dark Knight looks so bad ass now.^^
