Concealment...

[Kaiser2]

Some people have told me that Concealment doesn't work now, but I know it did around 6 months ago (I quit around that time). Why would it be turned off now?
Another thing, a week or two ago, I was using the skill over and over again, and one time, it said "You fade into the shadows." Perhaps it does work, but just very rarely? I didn't seem to turn invisible either. Perhaps you're only invisible from the perspective of others?

Here, tell me about how it is now.
