Bug? Unseen cannot be seen

[Sloth]

No pun intended, while playing Torment I encountered this bug that makes champion/fanatic/possessed or semi-unique Unseen monsters really unseen. Here are some pictures for you to make conclusions.







Last two pictures are the same semi-unique monster, first one was another one I have encountered at Horazon.
I couldn't take screenshots of the champion/fanatic/possessed I have encountered but I will and post some if I meet another.

i don't know if this is a bug or intended, but this annoyed me as well.

I don't think it's a bug, they appear only when they are very close to you (2 squares i think) and they must first do their "turn visible" animation, and if they don't do it then they are just invisible, even if you hit them.

Yeah, about that, one of them just came and killed me, and it was invisible as well. But as you said, maybe the "turn visible" animation doesn't trigger and they just remain invisible for me.

try call guardian dragons if you know or suspect those unseen things around. they are unseen but they are just there. dragon head will keep launch fire bolt to their location.

today i got killed by such real unseen things several times in torment mode too , i'd say they shall do it in torment , torment mode shall be more insane to beat. I like to be chase and scared by them but still find them out with golem

Sometimes in Catacombs a uniq Skeleton and his minions have this characteristic, and a uniq Balrog in Hell level 13 (?) is also invisible, but it depends on dungeon roll if they spawn.

Ah now I get it, then it's not a bug, it's just a feature from torment mode to make it more difficult, that makes sense lol
