Currently saving for Britomart, i'm at 480sq and 21tix rn, not that much but with the anniversary coming up (NA) and random campaigns i'll have like 1200 sq and 80 tix for her.
But for the most i ever saved, it was Galatea, saved 830sq and 100tix, only got her np1 initially (still mad about that), "luckily" i got a 2d copy later with interlude/rank up sq. At least i got her on other banners, so now she's np4 (i wouldn't have need to do that if i just had normal luck on her initial banner tho)
Oh, and as for resisting temptation, i just tell myself that i NEED to save to make sure i get my target to a good np lvl. Basically.
