And the fun thing is they are not the worst. The new Death Stalker has utterly insane stealth and stealth detection value. Even at level 14 with maxed out stealth, paranoia, 65% stealth detection googles and 10 Perception I cannot even begin to see them before they attack me. What is worse they bring me down to like 25% through a medium frequency shield and their stun dot is now paired with a dot which deals around 80 bio damage if you attempt to use an antidote.
In its current iteration you can already encounter them in Core City during Gorsky's quest line.
Just encountered this fucker while searching for the Ratking, I haven't even been to Core City yet. How is this supposed to be fun in any way? I can't detect it, I can't defend against it as it goes right through my shield. Even if I survive and don't get one-shotted right away, I'm down to 20% or less health and inflicted with that bullshit status effect that kills me if I try to heal or use antidote. Oh joy. The only thing to do is save scum and start throwing flares where I suspect the damn thing is. But even when I do find it, it must have insane defenses as I have next to no chance of hitting it. And I'm not playing on hardest difficulty either.
edit:
I actually thought I had it when I found it, stunned it with critical telekinetic hit and then set it on fire with a molotov cocktail. And then I realized it also regenerates 40 hp every round. Nice one.
edit 2:
Finally killed the fucker my setting a minefield and covering it with caltrops, then drawing him in. When he started taking damage from caltrops (thanks for the tip Tygrende) dropped a cocktail on the whole thing. Up he goes in flame. How this is supposed to work without save scumming I have no idea.
