Just got to the gacha screen, the TLDR is that it's basically Genshin except you have a 100% guarantee on both the character banner and the weapon banner.
>0.6% 5* rate, 5% 4* rate. Slightly higher rates on weapon banner.
>90 pity on characters, 80 on weapons.
>One time 100% rateup for limited characters, 50/50 for dupes after that.
>Limited weapons are always 100% guaranteed, no 50/50.
>Beginner banner that guarantees a 5* standard character with discounted pulls. Also all the standard are female so you can't brick your account.
