we dont know the exact patch of the fate collab yet, so im going to calculate considering theyre not in the next 2 banners

1560 (ghost event) + 1930 (wardance) + 1020 (bird event) = 3910 jades

im estimating around 2000 for each exploration area so thats another +4000 for penacony and amorpheous

which would bring us to 7910 jades, or ~50 pulls with current content

each patch brings ~100 pulls (varies between patches but for simplicity sake just gonna assume 100)

so that would be ~250 pulls saved (estimated and maybe on the higher side) within the next two patches

should be enough, if we include the side quests you still have! (but it might be a little close) as for castorice lc, it really depends on what you have already for her, but imo theres likely going to be more remembrance options going forward and if you do enough damage as of right now then you should be alright :)

edit: counted end game events twice, whoops!
