3 mill per Pero spend on N-Gacha give players 95% chance to get a SR Card like Akie.
With normal luck you only have to spend 1 mill to get Akie so the other 2 mill pero can be saved for next event wher you very unlucky.
So if you can collect 1-2 mill pero between every I alwasy have 95% chance to get the SR I need.
Is a free player I find the odd ok. For this first event I didnt know this but I was luck to get Akie anyway.
For future events I will be better prepaired. So far I like PeroPero.
