Be very careful if you want to play or spend in this game... Devs kind of scummy with their tricks, first multiple draw can only get from a group of character and NOT ALL character just like the 2.2% rate in the Pool said.. and first multi (10-20) is also limited to 1 SSR rather than the 2.2% chance.. I reroll 100+ account and thats the result I get..
Also the good SSR were locked behind paywall with no other way to get them.
Im sure they put some trick for re-roller so we dont get many ssr and the specific one EARLY!
