I checked exactly how many Elvia Calpheon Saunils you need for this title - 10,000. I don't have a proof but I can say I did it within 2 days doing only Saunils nothing else and I started at around 243 monsters in jornual and until 8242 I didn't get any title and today I did 1923 and it this moment I got title All-Nighter. You can trust me and update the missing info, I'm farming titles and always trying to help when there is missing info and gather it by myself.
