Immured Fury shadow nerf? Or am I just on a very unlucky stream?

Unlucky streak, probably. I find 1 fury per cluster on average.

Mid january they did fixed something up regarding immured fury. But it supposed to let them spawn more, not less:

Fixed an issue where The Immured Fury wouldn't spawn.

I keep seeing threads about 'shadow nerfs', is this actually a real thing?

That being said - I think you were quite lucky before finding even 2 per cleansed area. In my experience I find about 1 map every 1-2 cleansed areas.

I'm in the same boat

Huh I was just thinking to myself I’ve been pretty unlucky as well. 12 cleansed areas the last 2 weeks and only had 1 immured fury map pop up

Past few days, I have only found him like once, out of I'll say 7 areas. But I have had dry spells before. Typically I will say I see him about 1 out of 5 times on a average.

I’ve done about 15 clusters and only seen it 3 times -.-

Early on this league I was getting 1-2 frac orbs per cleansed area and didn't even know about the immured fury. Now I can do 2-3 cleansed areas and get nothing and the immures are few and far in-between. Just my personal experience, so not sure if there was a nerf, but feels like something is different. I've commented this same thing on multiple threads, so this isn't an isolated incident.

I’m having the same luck. So it’s not just you.

Whenever you get unlucky, it must be a shadow nerf. This is a unwritten law.

I would say on balance I average a little less than one. Clusters containing 2 are rared than those containing none. But most have one.
