You can get the same buff many times, it's based on promixity. It activates from some timer and there are announcements in the room. Eventually the 'mana orb' is removed.
You also get a sparkly aura, and if you get the buff many times in succession you end up looking like I did here: http://i.imgur.com/UfzZS4E.jpg
EDIT: You can see part of Kardui's message at the top of the screenshot.
do you know how to activate it? based on what u said, does it work like geffenia fountain?
