While chasing Collector's items (I have since abandoned the Scavenger Hunt)I put my invis on and was exploring the Wakening Lands (my first time!) and wandered near the Dragon Port when I spotted a large dragon. It was the Fabled Wuoshi! I maneuvered around the other side to get a clean screenshot. I got a good shot of her on resting. I got a second shot as she rose and roared (I always play with sound off, so I'm speculating a bit). When I pulled my windows back, I saw that I had taken several thousand hit points and was returning to bind point.
My question: does the screenshot camera use a flash? I fear that my tourist instinct may have given me away despite my invis.
