Yeah, with just the story nodes, it is pretty quick. I assume the original event had plenty of farming, possibly a lotto.

Can confirm there was a lotto. I remember this event at Late 2020. I don't really remember whether that's the original event or rerun, but definitely a lotto event.

It's one of the shortest Main Interludes.

Most of them would take hours of 5AP per quest to complete, it feels a lot like one of those "tower climbing" events. (╥﹏╥)

@Stray Bird ,Speaking of Prison Tower, I finished it last week, but I'm the only one waiting for the SERAPH Main Interlude, which may be free, in February or March, to get the BB, and take down Beast III, which was the only one missing, but first, I need to find out the true identity of Beast III when I start doing SERAPH's Main Interlude.
