Clouds.......

[kelvint23]

I have no idea how you guys are getting so many drops from clouds - I am constantly popping them and hit rate is so low on all reward types.

just set a low bar for it, don't expect too much. I've been playing this game for years and just been aware of this cloud thing few months ago. By that time I already had 20 Cloud Atlas collections. I guess they were accumulated accidentally when I was collecting golds. Just adopted the habit of tapping clouds recently, didn't count but I think the drop rate is 1/100.
