In my memory, I think I had seen it before,
a small icon seems orange like, and it said Auro of focus? You gain +3 concerntrate bonus blah blah blah.

But today I got reset my enhancement and had selected this, no icon showed. And when I standing beside my friends, they told me they have +3bonus on concerntrate skill, but still no icon showed, and when I highlighted their toon in my focus orb and press Z, there is no auro of focus, only auro of courage, auro of good showed.

Do I have a wrong memory or else?

Can someone confirm this for me, thanks!

BTW: I don't have a boost on my concerntrate skill either.
Is this only work on allies?
