Can all invaders(Achievement) spawn on normal mode?

Just wondering how far I have to go to farm em for the challenge.

Yup got them all (and all corrupted areas) in normal invasion ;)

I just need Judgement Apparatus for the invader achievement. Been running Vaal Ruins normal for 2.5 hours now zzzzz.

The worst I got in normal was the Black widow spider with 25% attack speed in a vaal map and a White spider in the map before the ledge. It had some sort of blink or smoke mine with blind, life regen and viper strike. I Could not kill it cause i just started the game so i had to have a friend kill it. I also had this massive Bone guy who has the allies cannot die mod right next to a king crab. Naturally i couldn't kill him either. I was just like WTFFFF both times. That's what i like about invasion though its infuriating at times haha.

Found Judgement Apparatus in Normal Caverns 1. It took a while but I can confirm he spawns there.

Just keep clearing from exit to exit until u get him.

But they each _do_ have some minimum area level they can spawn on, right? I tried running Fetid Pool on normal for about 2 hours yesterday (I find it quickest, since it is basically just a straighforward loop around a water pool in the middle), and I only got same 4-5 bosses.

I was going through the same thing. I remember asking general chat if invaders were random after 3 hours of farming forest. IIRC, I found all but 2 in normal; Judgement Apparatus and Firestarter. Someone said they found Judgement in act 1 normal. So if you want my opinion; they can all be found everywhere but either the spawn rates on some are very small or weighted somehow.

Killed fire starter for someone in normal prison earlier today.

Killed them all in Normal difficulty, in my experience most of them have a minimum level requirement, but by A3normal they can all spawn.
I also noticed how some have spawned only in indoor areas ( eg Judgement Apparatus) while others are outdoor only ( Kall Foxfly),but that could have been RNG...

Fetid pool is low lvl, imo you better try A2-A3 areas to find the missing ones.
