The only time I sacrifce my sleep was the tower climbing event. However, because I need to wait for the hp to be restored, the time will be longer, which means around 5-6hrs. I did that by using alarm to wake me up. I still sleep though because I am not a nocturnal person.

So yeah, that's probably the reason why I have never gotten myself into first half ranking due to fierce competition. But other than the tower climbing event, I just participate the other events leisurely.

R.I.P to the Valkyrie Crusade player who died just to get top 300 in rankings.
