Level 2 ring in one day?

Yeah, it's weird. I could get the ring and box for some characters on the second day of the event even though I never logged onto them at all. It didn't work for others though, specifically my CS, Merc, DS since they were created after the Legend update perhaps? For the first day, I didn't even have enough time to log onto every character, so the only character I logged onto was my NL to get the ring from 0 to 1.
