I was playing the other day as my mage, and i used what i think is either embers, and used it on a fliffy. It was sleeping, and didn't do anything but sleep even as it became crispy. But when i did the same to a fliffy which was up and running, it would go after me. I'm not sure if this is with all fliffies and other creatures or such which are sleeping, but it was kinda funny. http://myu.icyworlds.net:4901/data/screenshots/1485/71bfe72e.jpg
