"Hot Time Event" SP Reset

Can someone explain me how this event works?
Do you need to be log on in event time frame? (= leave maple on and you get scroll automaticly)
Do you need to talk with cassandra/accept light bulb in that time frame? (= need to be on and not afk)
Do you need to log on maple in that time frame and accept quest? (= deadly for servers and noone would be able to log on anyways)
Something else?

If soemone could tell me how it works i would really apreciate it. I only need for one char so it doesnt matter if i have to be logged on for whole day.
That if they dont give us reset scroll before event -.- But just taking this event as last option...

What he said, plus: is the sp reset a cash item I can transfer between servers or just a normal item that can be moved only via storage?
