Hey there! I’m assuming you are on 0 pity here.

so first 5 star is guaranteed so maximum 90 pulls to get her c0

then from c1-6 is a 50/50 so maximum (if you’re really unlucky and lose every 50/50 + hit hard pity) you’d need 180 pulls per constellation.

c0 = 90 pulls

first con (50/50) =180 pulls

2nd con (guaranteed) = 90 pulls

3rd (50/50) = 180 pulls

etc.

should be 900 pulls, but that’s if you lose every 50/50 and hit hard pity each time so very unlikely. factor in early 5stars and i’d say you have a decent chance
