Missing 1 Trial for Uber LAB

So I've going about a few weeks now and completed over 200 maps from tier 1 to tier 16.

Why am I still missing 1 trial. I know most would say its not important, but it would still increase my damage by 20%.

Am I doing something wrong? Is there a specific map pool for each trial? I've seen all the other trials at least 3 times. I am aware of the usual RNG gate POE likes to force, but this getting a bit out of hand.

As far as I know, there is no pattern or specific maps for trials unfortunately. The best thing one can do is find the global channel and request one or see if it is offered. I think it is 820 but probably verify that. Since I completed mine, I've probably only seen a handful of trials so I feel lucky I found mine when I did.

rng, just buy it

I have tracked Uber lab trials for the last 5 leagues, my personal average is 150 maps to get #6.
One league I was over 200.
SSF btw.

That sounds about right, although I have watched my level. Usually have 5 by low 80s or sooner but almost never get 6 until 90-92.

This league got 5 unique trials in the first 7. All normal. Will find at least 20-30 more before the last one turns up.

Just got my final trial at level 89. Been quite frustrating.
I have spammed low tier maps skipping most of the content to look for trials.
Make sure you take Zana missions and propecies. Since I got a few trials that way.

But this system is just too random and needs a rework. FFS just let Zana give you the trials your missing instead of a complete random trial.
Or something that makes it less RNGish.

Okay, I have to chuckle a bit. Just got the last trial - faster by far than any other league.
