Circlet of Shadow PC
 

Is the pre nerf insta cast invis helm still in game? If so could someone price check it for me?

CoS prenerf exists in game until 6 months into Velious.

They rot quite often at the chief camp. But get sold around 2-3k.

do they rot enough i could go there invis and wait for one?

I don't think it's a good idea to bank on a Circlet of Shadow rottting; I don't think there's much truth to this when you could easily corpse them or rotate them out.

I've gotten 2 from rots down there. I don't know many people who corpse them...

I corpse like... Rogue and Shaman Epic MQs, but 3k items mehh lol.

To the OP you could be down there for several days waiting on it. I suggest just leveling up and buying it once you get 2-3k.
