I've done this in the past but didn't know the two were connected. While battling 'Emma' a player asked all a question before Emma died.. I left the Emma room to the little notch in wall to answer his question so I wouldn't die.. After answering his question, I returned to Emma and everyone was like WTF? LOL! She had regenerated her power.. So I said Hm.. let me try that again.. After adequately depleting Emma life, I briefly exited her room & typed 'lol' when I returned.. Whola! Her power regenerated again! I did it a 3rd time just to be sure.. Yes, if u leave room to "type" in game chat.. Emma will regen life...
