>>14434377There's a historial option to check on the banner so keep this in mind:
counting from the last time you got a 5 star item (character or weapon) there's a countdown to 90 for every pull you make in a type of banner (character banner and weapon banner are treated differently), once you reach 90 pulls in a character banner without getting any 5 star item you have a 50/50 chance of getting the exclusive unit in the banner in this case ganyu, or a 5 star from the standard banner like Qiqi. However the next time you build up for the 50/50 on the SAME TYPE OF BANNER you have a 100% chance of getting the exclusive unit
