You can see that today started this event. Here you've the rewards:
Are you ready to claim the rewards?
Do you have gems to spend on this event or do you prefer to save them for another?
I wish I could spend my gems and help, but I'm saving to spend on The Biggest Spender and get some Hero that I don't have (and don't appear rolling).
Ps: Saouri commented on a failure in the description of the event and it's true, they should change the date (Event Duration)of when this event begins and ends.
