I'm confused. Casting Reflective Light toggles Major Prophecy, fine. But specifically how many seconds does it last? Makes all the difference in the world for planning out combat. Right now I cast it once every 4 to 6 skill casts, and just hope that I have Major Prophecy through all of them, but I don't actually know.
Tooltip doesn't say at all, while all the other skills' tooltips I use are very explicit on how long the Major/Minor property lasts.
Thanks in advance to whoever knows the answer.
