So I have a 948 summoning stones from watching the annoying ads then the time limit of the event is gone. I will change this to 5 star if in the next event, I still have those 948 from watching ads! I don't even know if the special monster have a cool look and have a good skills. So if I am watching ads for nothing then I will come back here and rate this 2 stars. Update: And now I can't retrieve my progress from FB. Well, okay, bye "play Ad to win" game.
