i dont do any quest cause dont worth it..but well if you want do that quest ...get a lot of millions ( i think that with 400++tickets you can make it but not sure) of pero and play the normal gacha....if want do it more faster then have some card reveal...i had done some like that but really dont worth..

Probably the best reason to use normal gacha is for lvl up cards if dont get bored easily...my sed is not so big either...1.3M still enough for get good rewards...:P
