I have spent about 50 I received a thunder god, champ, and pally. Though over on android same spent and.... Only a pally but that's also with nearly 90 day splayed and all those gems used too lol. Luck is fickle
It's luck based, it's just first impressions, it's the first you've done it and just got 3 assassins! Assassins are great. I got my thunder god via gems and 2 paladins in one 450 spin 30 minuites ago!
